- 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 and where the plank ends meet an adjoining structure or post per our Installation & Maintenance Guide, which can be found in Installation Resources.
- Is there a CONCEALoc® Hidden Fastener installation video available?
Yes. View the “TimberTech Decking Installation using CONCEALoc® Hidden Fastener" video on the TimberTech YouTube page.
- Are special tools required to install the CONCEALoc® Hidden Fasteners?
For our hand-driven 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 the TimberTech Installation Resources guide. The gun pail option of the CONCELoc Hidden Fasteners requires a pneumatic installation tool available through TigerClaw/FastenMaster.
- What are the CONCEALoc® Hidden Fasteners made of?
The CONCEALoc® fasteners are made from 304 stainless steel. The hand-driven screws are stainless steel, while the pneumatically driven screws 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.
- How many end cuts will one bottle of TimberTech® End Coating cover?
Each bottle of TimberTech® End Coating will cover approximately 250 end cuts.
You can purchase TimberTech End Coating on our Online Store.
- Where do I put TimberTech® deck lights on the stairs? How many should I install?
The TimberTech® Riser Lights are typically centered on the stairs. Some areas have codes specific to stair lighting. Be sure to check your local code requirements. We also offer post cap and post accent lights for more illumination at the top and bottom of the stairs.
The number of lights you install on your stairs is personal preference - so have fun with it! For inspiration, check out the TimberTech Lighting page.
- Can TimberTech Cortex™ fasteners be used for all decking?
TimberTech Cortex™ fasteners can be used on all TimberTech® decking for perimeter boards and stairs, except for ReliaBoard® or Terrain profiles. Cortex provides a discrete, hidden fastening solution for perimeter boards and stairs. Combined with TimberTech CONCEALoc® or FUSIONLoc™ for the main decking areas, you can enjoy a complete hidden fastening solution for the entire deck surface.
- What is the wattage on TimberTech® LED deck lights?
The wattage of the TimberTech® LEDs depends on the type of deck light you are using.
- Post Cap: 4 watts
- Island Cap, Accent, Under Rail, and Stair Riser: 2 watts
- In-Deck: 1 watt
- The optional dimmer w/remote for use with the 100W Transformer uses 20W
You can opt to use the transformer with 90 watts or the 150W PowerPack with a built-in dimmer, timer and dusk sensing photo eye. You can use up to 40 watts per circuit and 90 watts per transformer. Check out the TimberTech Photo Gallery to see how TimberTech Lighting can bring life to your dream deck!
- What sizes are available in TimberTech® Gate kits?
Our gate kits provide the components to turn a Premier Rail, Trademark Rail or RadianceRail pack into a gate using composite balusters to achieve either a 36” or 42” gate height to match the railing. Gate kits are available in Black or White both with black hardware.
- Do CONCEALoc® fasteners match decking colors?
CONCEALoc® and FUSIONLoc™ fasteners are not color matched to our decking. These hidden fastening systems are designed to combine ease of installation with the look of a flawless, fastener-free surface. CONCEALoc® --offered in Brown, and FUSIONLoc™, offered in Black--blend with the framing in the gaps between the deck planks.
With the exception of ReliaBoard and Terrain profiles, you can combine with TimberTech Cortex™ - available in multiple colors that complement our decking - for the perimeter boards and stairs, and you can enjoy a complete hidden fastening solution for the entire deck surface.
- Can I cantilever TimberTech® planks on my deck?
Terrain, Tropical, Legacy, TwinFinish, ReliaBoard, and DockSider can be cantilevered a maximum of 1”. Reliaboard and Terrain can only be cantilevered on the ends.
- Can I use glue or caulk with TimberTech®?
Do not use caulk to fasten TimberTech® 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.
- 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?
Routing should only be performed to create a 2” groove above each joist when transitioning from solid planks to grooved on a hidden fastener installation. Full details are available on Page 9 of the Installation and Maintenance Guide.
- What kind of fastener should I use with TimberTech®?
CONCEALoc is our most popular fastener for use with our grooved boards for a fastener-free finish. Cortex or TOPLoc are two other fastener options that can be used for just stairs and perimeters, or the entire deck. Cortex provides a discrete hidden fastening solution, while TOPLoc provides an engineered, color matched option.
Please note that Cortex cannot be used with the ReliaBoard and Terrain profiles. ReliaBoard cannot be grooved. It must only be face-fastened. Grooving ReliaBoard will void the warranty. Also, do not use CONCEALoc Hidden Fasterns or L-Brackets for stair installation.
Refer to our Installation Resources>
- Can I build my TimberTech® deck directly over an existing surface?
While TimberTech products are great for deck re-planking (removing old deck surface planks and installing TimberTech on code-compliant substructure), TimberTech planks CANNOT be installed on top of existing deck planks Please see our Installation Resources for proper ventilation requirements.
In areas with obstructed airflow such as roofs and on-grade applications, a minimum of 1-1/2” sleeper system supported by and connected to the substructure over which the deck is built is required.
- Can TimberTech® be painted or stained?
We do not recommend painting or staining TimberTech® decking. It is possible to paint our traditional composite lines like ReliaBoard, Twinfinish or DockSider. That said, TimberTech cannot guarantee the performance of paint, or other materials, 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 TimberTech® deck was constructed with DrySpace™ and pitches away from the house. Can I install the Combo Bracket tight to the bottom of the joist?
No. The Combo Bracket is a channel which collects water. When the Combo Bracket or Joist Cover is installed tight to the bottom of the joist, water cannot freely flow away from the Combo Bracket or Joist Covers and may have adverse results in the performance of the structural lumber. For full details regarding proper pitch and installation; please refer to the DrySpace Installation Guide.
- 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 view all TimberTech® color inspirations on the Browse by Color page.
- Which product is better for a heavily wooded lot?
Any TimberTech® product can handle a heavily wooded lot. For best performance, we recommend our capped wood composite decking found in the Legacy, Tropical and Terrain collections. Decking in our capped wood composite collections take scratch, stain and fade resistance to an entirely new level as all 4 sides are surrounded with a protective polymer 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, our TimberTech Legacy, Tropical and Terrain Collections come with 30-year Fade & Stain and 25-year Limited Warranties.
- 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, or 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. For grill mats, a natural fiber mat that does not hold moisture will provide the best protection.
- What preservatives are in TimberTech® decks' 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. We also recommend looking into our ADA handrail that meets the Americans with Disabilities Act (ADA) requirements.
- Which TimberTech® decking product resists fading the most?
Our TimberTech Terrain, Tropical, and Legacy Collections come with a 30-year Fade & Stain warranty, however, any exterior product will fade over time due to environmental conditions. Our capped wood composite lines of decking, including our Terrain, Tropical, and Legacy lines of decking will provide you with the best fade-resistant performance. These are backed by our 30-Year 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. All of our TimberTech products are tested to exceed the requirement of lower than a 200 on the flame spread index.
- I have a wood deck and want to do some replanking. Can I replace them with TimberTech® boards?
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 re-planking 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 with the specified pitch,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 TimberTech® DrySpace?
We do not recommend painting TimberTech® DrySpace 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. TimberTech® 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 TimberTech® DrySpace?
No. That would require penetrating the Joist Covers with nails or screws.
- Could I install TimberTech® 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. Read the full details regarding installations with a supporting beam or decks with a cantilevered area beyond the support beam.
- Will chemical treatments or stains damage TimberTech® DrySpace?
While common composite deck cleaners will not damage the DrySpace; any other cleaners should be verified to be vinyl safe.
- Can I install TimberTech® 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.
- What happens to the dirt and debris that falls through the gaps between the deck boards with TimberTech® DrySpace installed?
TimberTech® 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 are able to fall through and be channeled out of the DrySpace panels and through the optional gutter, which helps keep your space below clean and dry. Check out our DrySpace installation video and installation guide for more detailed information.
- Will TimberTech® 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.
- 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.
TimberTech 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.

- 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!

- 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.
