Do I need to gap my planks when I'm using CONCEALoc Hidden Fasteners?

The CONCEALoc fasteners provide consistent spacing between the sides of the planks. You will need to gap the ends at all butt joints per our Installation & Maintenance Guide, which can be found in the Installation Resources section of our Web site.

Is there a CONCEALoc Hidden Fastener installation video available?

Yes. View the "Grooved Planks - CONCEALoc" video on our web site in the Installation Resources section.

What tools are required to install the CONCEALoc Hidden Fasteners?

No special tools are required when using TimberTech grooved planks - just a drill/driver. We provide a #1 square drive bit with the screws and CONCEALoc clips. If using TimberTech solid planks, a route with TimberTech's CONCEALoc router bit will be needed to create a groove at each joist. You can find complete details on how to install CONCEALoc in grooved and solid planks in TimberTech's online Installation Resources.

What are the CONCEALoc Hidden Fasteners made of?

The CONCEALoc fasteners are made from 304 stainless steel. This material, with its high nickel content, will ensure a long life even in harsh environments. All screws are stainless steel, and numatic nails are coated carbon.

Can CONCEALoc Hidden Fasteners be used on angles?

Yes. Any angle up to 45 degrees can be achieved. On angles; offset the center of the fastener ½” towards the long point of the joist, so the screw will not exit the side of the joist when driven. Reference our Installation Resources for additional details.

Is it possible to replace a plank installed with CONCEALoc Hidden Fasteners, if it gets damaged after installation?

Yes. You can find complete details on how to do this in the TimberTech Online Installation Resources.

Saltwater climates are a perfect application for FenceScape products. Salt water will have no ill effects on FenceScape.

How does heat affect FenceScape?

The effect that heat has on FenceScape is similar to the effect it has on a wood fence. FenceScape was developed with reflective, inorganic pigments that minimize heat buildup.

What is the benefit of using the rail bracket?

The benefit of using our color-matched, powder-coated rail bracket is simply ease of installation. Using the bracket provides an alternative to toe-screwing the rail between the posts, eliminating the need to pre-drill. Rail brackets also give increased structural stability.

What kind of steel is in the rail?

The expanded steel in the rail is galvanized.

Can I use FenceScape with a new or existing wood sub-structure?

Yes. FenceScape posts and post covers may be used in conjunction with a new or existing sub-structure. This is a great solution if you have existing 4x4 posts set that are in good conditions. It also gives you the ability to mix and match components. FenceScape does not warranty product failure due to a failed sub-structure or anything that does not properly secure FenceScape. Be sure to consult your local building codes.


Can I cantilever TimberTech planks on my deck?

Yes. TimberTech Earthwood Evolutions, TwinFinish, DockSider, and ReliaBoard can be cantilevered 1” over the last support. TimberTech Floorizon planks should not be cantilevered.

Can I use glue or caulk with TimberTech?

Do not use caulk to fasten TimberTech Floorizon planks or to seal between any of our planks. This will impede the drainage of the plank and inhibit the natural expansion and contraction of the planks. Some contractors have reported success with Premium PL 2000 construction adhesive to support the fastening of other planks, but it is not recommended as the primary means of fastening the planks or fascia. Again, do not use caulk to seal between the planks.

Can I install my porch pillars or hot tub on top of my TimberTech deck?

Yes. Please remember the underlying joist system, not the TimberTech planks should be the primary structural supporting mechanism. TimberTech is not to be used as a primary structural load-bearing member.

Can I use a router on the TimberTech product?

Yes. If you are installing a solid profile such as our Earthwood Evolutions, TwinFinish, DockSider, or TwinFascia a router can be used. These TimberTech products will route similar to wood. TimberTech offers a CONCEALoc Router Bit to cut the perfect groove in TimberTech Solid Planks to use our CONCEALoc hidden fastener clips.

What kind of fastener should I use with TimberTech?

While installing TimberTech solid planks, we recommend using TimberTech's TOPLoc Face Fastening system or stainless steel or high-quality coated deck screws. For Earthwood Evolutions Plank, TwinFinish Plank and ReliaBoard: use a minimum #8 x 2-1/2". For DockSider Plank: use a minimum #8 x 3". Refer to our Installation Resources for more information. TimberTech grooved planks are installed using the TimberTech CONCEALoc Hidden Fastener. Follow the directions on the CONCEALoc box or bucket.
Our TOPLoc fascia fastening system eliminates the issues experienced with traditional fastening methods. The TOPLoc Fascia Bit and Fasteners are designed for proper fascia installations every time – allowing the fascia to hang in place.
Designed exclusively for TimberTech planks, TimberTech Cortex provides a discrete, hidden fastening solution for perimeter boards and stairs. Combined with TimberTech’s CONCEALoc for the main decking areas, homeowners can enjoy a true complete hidden fastening solution for the entire deck surface. Refer to our Installation Resources

Can I build my TimberTech deck directly over an existing surface?

See below for minimum space requirements for your TimberTech deck planks:
Earthwood Evolutions Plank, DockSider Plank, TwinFinish Plank and ReliaBoard
There must be a minimum of a 2" (nominal) sleeper system supported by and connected to the substructure over which the deck is to be built.
Floorizon Plank
There must be a minimum 12" high unobstructed continuous air space along at least three sides of the deck to allow for cross ventilation. Specific application requirements apply to Floorizon. Please see our Installation Resources for proper ventilation requirements.

Can TimberTech be painted or stained?

Although not recommended, TimberTech products may be painted or stained. TimberTech can not guarantee the performance of anything applied to the product. For painting information contact your TimberTech dealer or a local paint supplier. For further information on painting or staining your TimberTech decking refer to our Care and Cleaning Recommendations.

My deck was constructed with pitch away from the house. Can I install the Joist Covers tight to the bottom of the joist?

No. The Combo Bracket and Joist Cover is a gutter that does collect water. When the Combo Bracket or Joist Cover is installed tight to the bottom of the joist, water cannot freely flow from the Combo Bracket or Joist Covers.

Does TimberTech Decking come in a redwood color?

Our Caribbean Redwood is a great option if you're looking for a redwood color. You can also view all decking color options at Browse by Color or you can use our dealer locator to find a stocking retailer in your area.

Which product is better for a heavily wooded lot?

Any TimberTech product can handle a heavily wooded lot, though for best performance we recommend our capped wood composite decking found in the Legacy, Terrain, and Tropical collections.
Decking in our capped wood composite collections take scratch, stain and fade resistance to an entirely new level with a capped poly shell that protects against the outdoor elements.
With 13 color options across multiple price points, we are confident you will find the perfect decking. Plus, it comes with an added 25-Year Limited Fade and Stain Warranty and the same great 25-Year Limited Warranty that covers material defects, splinters, and damage from termites or rot that covers all our decking options.

What do you recommend to place under grills, chairs, and pots on decking from the Terrain, Tropical, or Legacy Collections?

We recommend using protective plastic, rubber, or felt leg pads on furniture and other items to help protect your Terrain, Tropical, and Legacy deck surface.
As you can see from our Decking Comparison Chart, our Terrain, Tropical, and Legacy collections have a high scratch resistance rating, but it's always beneficial to take the extra steps for protection.

What preservatives are used in the composite core to avoid rotting?

TimberTech composite decking is comprised mainly of high density polyethylene and wood particles, but we also add proprietary ingredients to our composite decking that help offset rotting.

Can TimberTech decking material be used for a wheelchair/walker ramp?

Yes, TimberTech decking and railing can be utilized to surface a ramp. We recommend consulting with a local contractor and check local building codes for requirements and best practices.
It’s also good to use a decking material that is slip-resistant.
You may also want to talk with your contractor about anti-slip strips for the ramp. We also recommend looking into our handrail that meets the Americans with Disabilities Act (ADA) requirements.

Between wood composite and capped wood composite, which TimberTech decking product resists fading the most?

While all TimberTech® products are formulated to help resist fade, any exterior product will fade over time due to environmental conditions. Our capped wood composite lines of decking, Earthwood Evolutions® Terrain, Tropical, and Legacy, lines of decking will provide you with the best fade-resistant performance. These are backed by our 25-Year Limited Fade & Stain Warranty. Traditional Composites like Reliaboard, TwinFinish and Docksider will weather as a result of the exposed wood fiber and surface patterns will blend over time and exposure.

Is TimberTech fire resistant?

Fire regulations and codes continue to become more important in the building industry. TimberTech is committed to manufacturing products that are compliant with these requirements and safe for our customers.
Below is a listing of our products that have been tested and their Flame Spread Rating.

  • XLM® All colors have a Class B Flame Spread Rating, and this is currently being tested for San Diego County requirements.
  • Earthwood Evolutions® All colors have a Class C Flame Spread Rating. Our Natural Terrain, Legacy, and Tropical lines are currently in testing.
  • TwinFinish®, DockSider™ & ReliaBoard™ All colors have a Class B Flame Spread Rating.
You can find a listing of TimberTech compliant products on the California Department of Forestry and Fire Protection Website.

Will TimberTech boards warp?

The benefit of a manufactured TimberTech deck board is that there is consistency among the boards. So as long as the material is properly stored on a flat surface prior to installation, and correctly installed, the product should not warp

Are all TimberTech products okay to use for piers?

All TimberTech® deck planks work well in a dock or pier application. Our low-maintenance decking will leave you with more time to relax near the water or go fishing off your dock! Our most common product used for a dock or pier is DockSider™.
Our DockSider planks, with a unique 24-inch on-center span, are great for heavy-use public places and docks near water. In fact, New Jersey chose TimberTech DockSider decking to rebuild their boardwalk that was destroyed by Hurricane Sandy. It stands up to sun, sea spray and sand very well.
Be sure to take structural framing joists spans into consideration and check your local building codes for the construction requirements in your area before starting any project.

Can carpeting be installed or an area rug be used over a three-seasons glass enclosed TimberTech deck?

Area rugs can be a fantastic way to add color and warmth to any space, including your three season’s room. We suggest that the rug be large enough to anchor and support the gathering space, yet it should allow circulation flow. In fact, airflow is important to prevent moisture build-up from beneath the deck, so check your elevation and ventilation of the substructure so the rug does not impede airflow. Please be aware of the type of decking and the type of area rug that you are considering.
We do not recommend installing carpet over your TimberTech deck, because we have not tested for it.

I have a wood deck and need to replace some boards. Can I replace them with composite decking?

Yes, you can replace wood boards with composite, though there are a few factors to take into consideration. First, you will want to make sure your substructure is code-compliant and can hold the extra weight of a TimberTech composite board. The thickness of the board is also important so that you continue to have a smooth decking surface. You can find with thickness of our products on each of the product pages. So although replacing old wood deck boards with composite can be done – you probably cannot get the look you want, because the boards will not match.
If you want your entire deck to match – which is what we recommend – we do have another option. If your substructure is code-compliant, you may want to think about replanking your entire deck with all composite material!

Is there a problem with heat build-up on composite?

Composite decking products, as with most outdoor building products, can retain heat especially after a long day in direct sunlight. At TimberTech, we have taken steps to minimize heat build-up with certain formulations of our composite decking product. If you're building a deck that will be in direct sunlight, we suggest looking for lighter color decking options.


Will the DrySpace Combo Bracket or Joist Cover cause my deck to rot?

No. When properly installed the Combo Bracket or Joist Cover channels water away from the house and out of the Combo Bracket or Joist Cover. This also allows for airflow between the Combo Bracket or Joist Cover and joist.

Can I paint DrySpace?

We do not recommend it because of the maintenance issues.

Can I splice panels together to save material?

No. There is no way to make a joint between the Joist Covers and/or Panels that will prevent leaks. DrySpace comes in 12’ and 16’ lengths that allow for seamless installations. The 16’ kits are ideal for DrySpace installations where the joist cavities are 8' long.

Can I install a more decorative ceiling under DrySpace?

No. That would require penetrating the Joist Covers with nails or screws.

Could I install DrySpace by using F-Brackets only and not the Combo Bracket (Joist Cover/F-Bracket combo)?

No. The Combo Bracket (Joist Cover/F-Bracket Combo) must be used to collect any water that drains through or around the joist.

Can I run the Panels over the top of a beam?

Panels must always stop 3” from the beam. In most cases the low point of the Panel will interfere with the beam causing water to dam on the Panel. Combo Brackets and Joist Covers should stop 1” from the beam. For more information on beams, refer to our Installation Instructions.

Will chemical treatments or stains damage DrySpace?

No. Common, off-the-shelf stains and chemical wood cleaning treatments have no adverse effects on DrySpace.

Can I use TimberTech DrySpace with TimberTech Floorizon Deck Planks?

Yes. With proper installation, TimberTech DrySpace can be used with Floorizon Planks. The moisture will be carried away from underneath the Floorizon Planks. It is the moisture underneath the Floorizon Planks that could cause cupping. In addition, since the V-Panels are cut 3" from the beam or rim joist, there should be some air flow around the planks.

Can I install DrySpace by myself?

Yes. Complete, easy-to-follow instructions come with your DrySpace purchase or you can refer to our Online Installation Resources. Installation is easiest with two people. You are likely to have the tools and materials you need, or they are easy to find at your local hardware store.

Can I get more information on TimberTech DrySpace?

TimberTech DrySpace is our under deck drainage system that collects and channels moisture from the spaces between your planks. It's ideal for second-story decks and is made of solid extruded vinyl for maximum strength, durability and weather resistance.
DrySpace effectively turns lower level patios into extra leisure and storage space – creating a usable dry space under your deck. It's great for creating more functional space to hang out with friends and family.
The off-white color design lightens and brightens the area under a deck, giving that space a crisp, finished look.

What happens to the dirt and debris that falls through the gaps between the deck boards with DrySpace installed?

DrySpace is a deck drainage system that collects water and debris that falls between the gaps in the planks and channels it away. When a deck is installed using the proper gapping requirements between planks and DrySpace is installed with the proper pitch, dirt and debris is able to fall through and be channeled out of the DrySpace panels and through the optional gutter helping to keep your space below clean and dry. Check out our DrySpace installation video and installation guide for more detailed information.

Will DrySpace fail if snow melts and then freezes on the DrySpace?

If the TimberTech DrySpace has been installed with the proper pitch as defined within the Installation and Maintenance Guide, the majority of the melt off would channel out of the panel rather than freeze. If minimal freezing would occur, TimberTech DrySpace has been tested to support 25 lb/foot. Check out our DrySpace installation video and installation guide for more information.


Are the RadianceRail kits actually a full 6’ and 8’?

All are designed to be 6’ and 8” or measured from center of post to center of post. The additional material is provided to allow for angles and end cuts/trimming.

I have a chip in the cap stock (outer layer) material on my RadianceRail; can I repair it or touch it up?

Yes. Automotive touch-up paint such as Duplicolor 2 in 1 Scratch Fix works well and is available at most department or automotive retailers. For Coastal White use universal gloss white and for Classic Black use universal flat black.

We are installing RadianceRail Express on a curved deck, will the brackets swivel like regular RadianceRail?

While RadianceRail Express Brackets are fixed and do not swivel, however they do accommodate angles up to 45 degrees.

How close to the rails can you safely have a barbecue grill without damaging TimberTech Railing?

The distance from our railing can vary depending on the type of grill and size. Most grill manufacturers will have recommendations for placement in proximity to vinyl siding, and you can follow those same recommendations for TimberTech Railing.
To protect your deck, a grill mat can be placed under the grill to avoid grease spills. You will want to make sure that the grill mat is safe for your composite decking. Happy Grilling!

What different styles do you have for TimberTech railing?

We currently have six different styles of railing.

As you can see in the chart, each railing options offers a different look and features.

What options are available with the TimberTech decking systems for a glass view?

We do offer a Glass Channel Kit that allows for the installation of glass infill with TimberTech railings including RadianceRail®, Evolutions Rail® Contemporary, and Evolutions Rail Builder. The Glass Channel Kits are offered in White and Black and in 6' lengths. The glass is sold separately, and always check your local building codes before starting any project.
If you are looking for a more modern looking railing – check out the TimberTech Evolutions Rail with CableRail infill. This railing will give you those beautiful unobstructed views similar to a glass infill. We have a partnership with Feeney, Inc. for the first composite railing system designed to work with CableRail. You will love your view with this high-style railing!

Can TimberTech railing and decking products be curved or bent?

TimberTech railing and decking products can be curved or bent using heat and force to create custom shapes. Because curving/bending is performed by customers on their own or by third-party fabricators, TimberTech cannot guarantee the integrity or performance of such applications, including the potential effect to the products’ structural rigidity, aesthetics or other product attributes. Any problems to the decking or railing products resulting from curving/bending are expressly excluded under TimberTech’s Limited Warranty. TimberTech recommends that all designs be reviewed by a licensed architect, engineer or local building official before installation.

Care and Cleaning

What do I do for scratches, nicks or cuts?

Scratches and nicks will weather to a similar match in 8-10 weeks; the time frame will vary based on exposure and climate. Surface scratches on the fence boards, rail and the 5-1/4" x 5-1/4" post may be repaired by applying heat to the surface. This can blend the damaged surface area back in by encapsulating the wood fiber and resin back together. This can be performed with a soldering iron such as the LSP-25 manufactured by Wall Lenk Corporation which is a cordless butane powered soldering iron. The LSP-25 retails for approximately $15 and is readily available at most building supply and hardware stores. Standard soldering irons will work as well. Best practice would be to experiment on a piece of scrap material to determine the best heat range as every soldering iron will vary. A rounded tip design will work the best to blend the scratched material back in.
Minwax® Wood Finish™ Stain Markers in an Early American color enable touchups of FenceScape’s steel reinforced rail, fence boards, posts and post covers. Simply apply the marker to the damaged area and wipe off any access wood finish. It dries to a nice color comparable to the FenceScape Mountain Cedar finish.

Can I use rock salt or ice melt on a TimberTech Deck?

We recommend using either rock salt or calcium chloride for ice removal. Either of these can be used without damage to the surface of your deck. These products may leave a white residue, but it can be removed easily by either rinsing with water or a mild soap/water solution once the weather warms up a bit (You don't want that water freezing again). For more information, visit the care and cleaning section on our website!

Can you power wash a TimberTech deck?

First, remember to spray in the direction of the brush/grain pattern to avoid damaging the product. Always take the proper safety precautions when operating a power washer. Be sure to hold the power wash wand at approximately a 30 degree angle. A fan tip must be used on the wand or damage to the decking will occur.
For TimberTech wood-plastic composite and capped-composite decking, the recommended maximum pressure is 1500 psi.
For more information, check out the care and cleaning page.


What is the maximum span of FenceScape?

FenceScape support rails are designed for a maximum span of 8' center-to-center of the posts.

Can I use glue or caulk?

Glue or caulk is not required or recommended to be used with FenceScape products. However, FenceScape decorative post caps may be secured with stainless steel finish nails or exterior caulk.

Can I use a router on FenceScape?

Yes. FenceScape fence boards will route just like wood. Routing of the FenceScape rail is not recommended due to the embedded steel core.

Is it still recommended to create a loop for the TimberTech LED Lighting's wiring?

No, it is not necessary to create a loop with the TimberTech LED Lights. You can end the run at your last light.

What is the maximum joist spacing for the Terrain, Tropical, and Legacy collections using CONCEALoc Fastening?

If you are installing the plank perpendicular to the joist the maximum spacing is 16" on center. When installing on a 45 degree application the maximum joist spacing is 12" on center. For the most up to date installation information, please visit the Installation Resources page.

Do you need to use a TimberTech Transformer with the LED Lighting product?

To maintain the 5 Year Warranty for our Lighting, our LED Lighting products should be installed using the TimberTech Transformer. We have tested our lighting and transformer together, and we are confident in their performance. We think you'll love them!

What is the spacing for TimberTech stair stringers?

The answer depends on the line of decking you are installing. Docksider is 21". Twin Finish is 12". Tropical and Legacy 10". ReliaBoard is 9" and Terrain is 16" when used as a veneer. As always, we recommend consulting a building professional and referring to the TimberTech Decking Install Guide before starting any project. For the most up to date installation information, please Installation Resources.

Can TimberTech Decking be installed in cold weather?

Yes, TimberTech decking can be installed in cold weather, but the installation requirements may change a bit depending on the temperature. For example, for temperatures below 45 degrees Fahrenheit, pre-drilling is required for all TimberTech composite and capped-composite products.
The gapping requirements also change depending on the temperature. You can find those specific requirements in the Decking Installation Guide. We always recommend contacting a professional builder or contractor before starting your dream deck project!

Does TimberTech have a bench and/or planter system?

TimberTech® does not offer a bench or planter kit – but it can be done!
First, there are two things you should remember. Always check your local building codes before starting any project, and TimberTech decking cannot be used as a support or structural system. You will need to build the framing structure first, and then place TimberTech over it. We recommend working with your local contractor to help design and build your benches and planters.
TimberTech benches and planters can be built using any of our decking products, but TwinFinish® decking was specifically designed for this purpose. This two-sided composite decking plank is perfect for built-in decking projects. The plank’s VertiGrain side makes an attractive and slip-resistant walking surface, and the flip side’s serrated texture make the perfect contrast for stand-out deck built-ins.
Not only does it add to the overall look and experience of your deck – but it also completely matches!

How do you install TimberTech railings on concrete?

TimberTech Secure Mount Post is a great option for the installation of TimberTech railing on a concrete surface. The Secure Mount Post can be installed directly on composite decks or concrete surfaces, and no treated 4x4 post is needed!
Check out the Secure Mount Post Installation Guide and the Railing Installation Guide for instructions, and always consult local building codes prior to installation.

Does TimberTech decking require pre-drilling to install?

There are a few instances when you will need to pre-drill while installing a TimberTech deck. If you are using TimberTech TOPLoc fasteners or an alternative composite deck screw, then pre-drilling is required when within 1 ½” of the ends of the planks, as well as for installation in temperatures below 45 degrees fahrenheit. This is to help avoid splitting of the plank and screw shearing. For more information, be sure to check out our Decking Install Guide.

Can I use TimberTech as a joist?

No, you cannot use TimberTech as a joist. TimberTech is not intended for use as columns, support posts, beams, joist stringers or other primary load bearing members. TimberTech must only be supported by a code-compliant substructure. For more information check out our Installation and Maintenance Guides.

    Photos are required to resolve any claim. You may upload up to 5 photos with the initial registration. Additional information may be requested and supplied after registration is complete. Photos should include overall views from each side of the deck to illustrate structure, deck elevation, and general surroundings. For elevated decks, photos of the understructure are helpful. Specific photos illustrating the problem area(s):

  • For concerns of structural movement or warping, placing a straight edge on the deck surface provides a reference point to better illustrate the area of concern. Common straight edges are a builder’s level, board, broom handle, etc.
  • Photos specific to areas with aesthetic concerns do not require a straight edge reference point.
  • Clarity of photos will expedite the review process
  • Each image file is limited to 5 MB
