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

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. Confirm that the thickness of the new TimberTech board is the same as the wooden board it replaces to ensure your deck remains smooth and flat. You can find the thickness of our products on their individual product pages.

Although replacing old wood deck boards with TimberTech boards can be done, it can result in an undesirable patchwork appearance. A better option, if your substructure is code-compliant, would be to replace your entire deck with all TimberTech deck boards.

TimberTech Advanced PVC products do not require pre-drilling.

For TimberTech Composite decking, there are a few instances when you will need to pre-drill. Cortex fasteners require a 7/32’’ pre-drill. 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 boards, as well as for installation in temperatures below 45 degrees Fahrenheit. This is to help avoid splitting the board and screw shearing. For more information, be sure to check out our Decking Installation Guide.

Routing should only be performed to create a 2” groove above each joist when transitioning from solid boards to grooved on a hidden fastener installation. Consult the respective Installation and Maintenance Guide for more information.

Do not use caulk to fasten TimberTech boards or to seal between any of our boards. This will impede the drainage of the board and inhibit the natural expansion and contraction of the boards.

Saltwater does not negatively impact TimberTech decking. All TimberTech deck boards are safe to install near saltwater. We recommend using 316 stainless steel fasteners when installing near saltwater.

Yes, our decking can be installed in any temperature. For best results with TimberTech Advanced PVC decking, keep the boards as cool as possible during attachment.

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 Guide.

While TimberTech products are great for replacing an old deck using an existing sub-structure, TimberTech boards CANNOT be installed on top of existing deck boards.

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 products when face fastening. For TimberTech Composite, the gapping requirements also change depending on the temperature. You can find those specific requirements in the decking Installation Guides. We always recommend contacting a professional builder or contractor before starting your deck project.

Maximum joist spacing on a deck’s surface for standard TimberTech deck boards is 16″ on center for residential applications. TimberTech Advanced PVC MAX boards can span 24″ on center. For stairs, landings, angled installation of deck boards and commercial applications, please refer to our decking installation guides for the joist spacing required. You should always follow local building codes.

Yes, you can install TimberTech deck boards yourself. Installation guides are available for reference. Check out this article that provides more information about what it takes to install it yourself.

TimberTech Decking requires a properly fastened, structurally sound and secure frame. A minimum of a 1 1/2″ sleeper system is required. Be sure to follow all recommended guidelines for installing TimberTech Decking.

Depending on the line of decking you are installing, the stair and landing requirements differ. Refer to the TimberTech Decking install guides and local building codes for requirements.
