Decks and patio covers in Northwest Washington

Decks, stairs and railings, and covers that let you use the yard through the wet months. We build and rebuild them across Skagit, Snohomish, Island and Whatcom Counties, in composite or wood, and match a cover's roofing, flashing and gutters to the house.

How we handle a deck or cover

At the site visit we look at how you want to use the space, where the sun and rain come from, where the water will go, and how the new work meets the house. A cover should look like it belongs there. On a patio cover in Marysville, the shingles, flashing and gutters were matched to the house.

We draw the layout, and bring in a structural engineer when the design calls for one. The written proposal lists the footings, framing, decking or roofing, railings and finishes line by line, so you can weigh composite against wood, or a gable roof against a shed roof.

Rebuilds start underneath. On an apartment walkway in Sedro-Woolley, the rotten joists were replaced and a low section was shimmed level for drainage before any new composite went down.

During the build you get dated progress photos, and every change goes in a signed change order. At the end we walk it with you.

Questions people ask

Composite or wood?

Both work here. Wood can be stained to match the house and repaired board by board. Composite needs less routine upkeep. We can put both in the written proposal so you can compare them line by line.

Can a patio cover match my house?

Yes. We match the roofing, flashing, gutters and trim colors to the house, and we can finish the underside with a stained wood ceiling.

Can you add lights or a fan under the cover?

Yes. Lights, a ceiling fan and outlets under a cover can stay with us under our residential electrical license, WASHIC*743DE.

My deck feels soft in spots. Can it be saved?

Often the framing underneath is the problem, not just the boards. We look under the deck at the site visit and tell you plainly what can stay and what needs replacing.
