Credentials & honors
  • Registered in both statesWA L&I + Idaho DOPLRegistered in both states. Holds a current Washington L&I registration and a current Idaho contractor registration, so it can legally take jobs on both sides of the state line.

Timber Construction LLC keeps a narrow focus: custom decks and larger outdoor structures, designed and built for homes in Spokane. The service list is short on purpose, centered on the work that happens outside the house rather than inside it. The company advertises work across Washington and Idaho and describes itself as locally owned and family-owned, with a founding year of 2001 on its own site.

Design and construction of custom decks sit at the center of what Timber Construction says it does, along with bigger outdoor builds that go beyond a simple platform off the back door. The work is residential. The company advertises a lifetime warranty, which is its own claim, and the state lists Christopher Patterson as a principal since 2021. Earlier state registration under the same business name dates back to 2012. Work tends to come through referrals and repeat customers rather than advertising. This is a good match for a homeowner in the Spokane area planning a custom deck, from the layout and design through the build. It's an outdoor structures shop, so interior remodels, kitchen or bath work, or structural framing inside a house fall outside the work Timber Construction describes. Anyone planning a deck alongside an addition or interior project would likely be lining up a separate contractor for the indoor part. Before comparing deck bids, write down the size and shape you want, the height off the ground, and how the deck meets the house, since a ledger attached to an older Spokane home's siding is a different job than a freestanding structure. Note the decking material, railing style, and whether stairs, lighting, or a covered section are included. Ask each builder whether the quote covers the permit, footings deep enough for local frost, and removal of any old deck. Get warranty terms in writing so you can compare what each one actually covers.
