Deck staining and sealing
in Bellingham and Ferndale

A Bellingham deck takes more weather than most. 40 inches of rain, cedar pollen, moss under the rails, and UV when the clouds finally break. Without stain, the wood grays, splits, and rots. A proper stain job every 3-5 years keeps the deck looking new and adds a decade to its life.

Most residential decks in Whatcom County run $770-$2,000 including rails, steps, and spindles. That range covers a recoat on a deck whose finish is still sound. Heavily weathered decks that need mold remediation, sanding back to sound wood, or board replacement price as restorations, typically $3,500 to $5,500 depending on size and condition. We tell you which one your deck is at the walkthrough, in writing. We prefer semi-transparent oil-based stains for new-ish wood and solid stains for anything over 10 years old. The key is prep: pressure wash, let dry for 48+ hours, light sand, then stain in a dry weather window.

What it costs

How the job runs

1. Walkthrough & quote

   We measure the deck, check for rot, look at the existing finish, and write a line-item quote.

2. Pressure wash & sand

   Strip existing finish where needed, pressure wash with deck-safe cleaner, then wait 48 hours for full dry.

3. Stain application

   Apply stain by brush, pad, or sprayer depending on product. Two coats on high-wear surfaces.

4. Cure & walk

   Allow 24-48 hours for full cure before foot traffic. Final walkthrough checks every board.

Deck sealing and staining in Ferndale

Ferndale is about ten miles north of our Bellingham base on I-5, so it is a normal service day for the crew, same $770-$2,000 range as in town, no trip charge. We stain and seal decks in the Ferndale city limits and on the rural properties around it: out Northwest Road, along the Nooksack toward Slater Road, and west toward Birch Bay.

Two things change once you cross the county north of Bellingham. Decks are bigger, so a 1990s rancher on acreage might carry 500 to 700 square feet of boards on two levels where a Sehome bungalow has 180. And the weather splits at the freeway: west of I-5 the air still carries marine moisture and decks grow the same green film we see in Fairhaven, while east of it the boards dry faster and fade in the sun instead. That decides the product. Shaded decks under big-leaf maples get a mildew-resistant semi-transparent stain and a shorter recoat cycle; open, sun-facing decks get a solid or a heavily pigmented stain that holds color.

Sealing and staining are two jobs. A clear sealer stops water and shows the grain but gives no UV protection, so bare cedar still goes gray in one Ferndale summer. A penetrating stain does both. If your deck was sealed three years ago and still beads water, a wash and recoat is usually enough. If it has sat bare through several winters, plan on a full strip, brightener, and probably some board replacement, which prices as a restoration at $3,500 to $5,500.

The dry window is the same as Bellingham: we need 48 hours of dry wood before stain goes on, and the reliable stretch runs mid May through September. More local detail in our Ferndale and north county deck staining guide and on the Ferndale service page.

Common questions

How much does deck staining cost in Bellingham?

Most residential decks run $770-$2,000 or roughly $3.30-$6.60 per square foot including rails and spindles for a recoat on a sound finish. Heavily weathered decks needing mold remediation, sanding, or board replacement price as restorations, typically $3,500 to $5,500. Price depends on square footage, condition, and stain choice.

How often should a deck be restained in Bellingham?

Every 3-5 years for semi-transparent stain, every 5-7 for solid. Shaded decks with moss need more frequent attention. We can do a cleaning-and-recoat for less than a full redo if the finish is still sound.

Ferndale service area and pricing

Yes. Ferndale, Custer, and the Birch Bay side are all inside our regular service area at the same pricing as Bellingham. Estimates are free and we come out to measure, check moisture, and look for rot before writing the number.

Can you stain a brand-new deck right away?

No. New pressure-treated lumber needs 3-6 months to dry before stain can penetrate. Cedar and redwood can be stained sooner. We check moisture content during the walkthrough.
