Deck Contractors in Mount Vernon, WA

Mount Vernon summers are the reward for Mount Vernon winters. When the gray finally lifts off the Skagit Valley, the season that starts with the Tulip Festival and runs through long, dry August evenings is exactly what a good deck is for. Alpine Exteriors builds decks across Mount Vernon, from the older neighborhoods near the downtown riverfront to the newer plats climbing Little Mountain, and the valley's particular climate shapes how we build every one of them.

Building for Skagit Valley Moisture

The valley floor holds moisture like few places in western Washington. River fog off the Skagit settles in overnight for weeks at a stretch in fall and winter, and low-lying yards can stay soft well into spring. For decks, that means two things. First, anything wooden near grade lives in near-constant dampness, so ground-contact-rated framing, proper footing depth, and generous clearance under the structure are not optional. Second, unsealed cedar surfaces gray, mildew, and grow slick faster here than on drier ground, which is why most of our Mount Vernon clients now choose capped composite decking that cleans up with a hose.

Hillside homes on Little Mountain and the east side face a different challenge: elevated decks on sloped lots that need real structural design, not rule-of-thumb framing, to carry a crowd safely above the grade below.

Decks That Match How the Valley Lives

Across 25 years of exterior work in northwest Washington, we have built decks for farmhouses, ramblers, and brand-new construction, and we design around how each household actually uses its outdoor space.

• Covered and partially roofed decks that extend the season on both ends of the valley's short summer
• Farmhouse porch rebuilds that replace sagging original structures on Skagit County's older homes
• View decks with cable railing for hillside lots looking over the valley and the river
• Low platform decks that turn flat, soggy backyards into usable outdoor rooms

Repairs and Rebuilds, Judged Honestly

If your existing deck is merely tired, we will say so and quote the smaller job. If the ledger, posts, or joists are rotten, we will show you the screwdriver test rather than ask you to take our word. More than 2,000 completed projects have taught us which decks can be saved and which are past it.
