What is the warranty on TimberTech composite decking sold in New Brunswick?

TimberTech's premium Pro line carries a 25-year fade and stain warranty along with a 50-year structural warranty, making it one of the strongest warranty packages available on composite decking sold in New Brunswick. The TimberTech Edge line, which is the mid-range product, carries a proportionally shorter warranty but still significantly exceeds anything offered on pressure-treated lumber, which typically comes with no performance warranty at all beyond the preservative treatment itself.

Understanding what these warranties actually cover, and what they exclude, is essential for New Brunswick homeowners before making a purchasing decision. The 25-year fade and stain warranty on the Pro line means TimberTech guarantees the board surface will not excessively fade, stain, or discolour under normal residential use for a quarter century. Given that New Brunswick decks face Maritime sun exposure, salt air along the Fundy coast, heavy precipitation, and sustained humidity, this is a meaningful commitment from the manufacturer. The newer capped composite products like TimberTech Pro resist fading by over 95 percent across 25 years, so the boards you install today will look remarkably similar in 2051.

The 50-year structural warranty covers the integrity of the board itself, guaranteeing it will not split, crack, rot, or suffer structural failure from normal use and weather exposure over five decades. For context, a pressure-treated wood deck in New Brunswick typically starts showing significant deterioration within 8-12 years even with annual maintenance, and most are replaced entirely within 15-20 years. A 50-year structural warranty fundamentally changes the economics of deck ownership.

However, there are important exclusions that New Brunswick homeowners must understand. The most critical one is that TimberTech's warranty does not cover structural damage resulting from improper installation. This specifically includes incorrect joist spacing. All TimberTech composite products require 12-inch on-center joist spacing. If your deck is built with 16-inch spacing, which is standard for wood decks and a common shortcut taken by contractors unfamiliar with composite requirements, any sagging, flexing, or board damage that results will not be covered. This is the single most common reason composite deck warranty claims are denied across the industry.

The warranty also requires that the decking be installed according to TimberTech's published installation guidelines, including proper gapping for thermal expansion, adequate ventilation beneath the deck surface, and the use of approved fastener systems. New Brunswick's temperature range, which can swing from minus 30 degrees Celsius in winter to plus 35 degrees in summer, causes composite boards to expand and contract measurably. If expansion gaps are not left during installation, the boards can buckle, and that damage falls outside warranty coverage.

To keep your warranty valid, TimberTech requires reasonable maintenance, which for composite decking is minimal. Cleaning twice per year with a composite deck cleaner addresses any mildew or dirt buildup that Maritime humidity encourages. No sealing, staining, or painting is needed, and in fact applying such products could void the warranty. For winter care, use calcium chloride for ice removal rather than rock salt.

Warranty claims are handled directly through TimberTech and typically require proof of purchase, installation date, and photos of the issue. Keeping your purchase receipts and a copy of your contractor's installation details is worthwhile insurance for a product that is warranted to last half a century.
