Bellingham gets close to three feet of rain in an average year, and most of it falls in the months when nobody is looking at their deck. Then July arrives, the clouds lift off Bellingham Bay, and everyone in town wants to be outside at once. A deck here has to survive eight soggy months to earn four spectacular ones — and that is a genuine engineering problem, not a marketing line.

Decks Designed for a City That Lives Outside in Summer

We build and replace decks all over town: view platforms on South Hill catching the sunset over Lummi Island, family decks behind Sunnyland and Columbia craftsman homes, and big entertaining decks near Lake Padden and Whatcom Falls Park where the trees never stop dropping needles. Shade and organic debris are the two things that kill Bellingham decks early, because both hold moisture against wood long after the rain stops.

That is why we spend as much effort on what you cannot see as what you can. Ledger flashing is the number-one failure point we find on older Bellingham decks — a rotted ledger connection is how decks separate from houses — so ours get proper flashing, standoff details, and structural fasteners rather than the lag-bolts-through-siding shortcut common in decks built decades ago.

Cedar or Composite?

Both work here, honestly. Western red cedar looks at home behind a 1920s craftsman and takes stain beautifully, but it wants maintenance. Modern composite and PVC decking shrugs off the moss and algae that our marine climate grows on every horizontal surface, which is why it has become our most-requested surface for shaded lots. We will walk you through the real trade-offs, not a brochure.

What a Deck Build With Us Looks Like

After 25 years in business and more than 2,000 completed projects across Whatcom County, our process is boringly predictable — in the best way:

  • A free on-site estimate where we measure, check grades and setbacks, and talk through design
  • Footings and framing sized for our wet soils, not a generic span table
  • Hidden fasteners, flashed ledgers, and ventilation details that fight rot before it starts
  • A final walkthrough where you inspect every board and railing with us

We handle permitting with the City of Bellingham and Whatcom County when your project requires it, and we design railings to preserve the view you are paying for — cable and glass panel systems are popular on the hillsides for exactly that reason.

Backed for 25 Years, Because We Plan to Be Here

Every deck we build carries our 25-year workmanship warranty. That is not a number we picked for symmetry; it reflects how we flash, fasten, and frame. If you have a deck that flexes underfoot, shows dark staining at the posts, or simply was not built for how your family actually uses the backyard, get on our schedule for a free estimate — summer in Bellingham is too short to spend it on a deck you avoid.
