Stanwood Siding Contractor — Farmhouse, Coastal Exposure, Camano Island Access
Stanwood is a small agricultural town at the mouth of the Stillaguamish River, minutes from Camano Island. The combination of river delta moisture, saltwater proximity from Port Susan, and wide-open agricultural wind exposure makes this one of the tougher environments for siding in Snohomish County. We work on everything here — century-old farmhouses with original lap siding, 1970s ranches, and newer homes where builders didn’t account for the coastal influence.

Real reviews from our Google profile — unedited, from real projects.
“We recently had Paul with GP General repair a damaged corner protector and sidings. His estimate was reasonable, his availability was timely, and his job was excellent. Our home hadn’t been re-painted in a while and the paint had considerably faded, yet he was able to match the color perfectly. Now we know who to turn to when in need of another repair work.”
“GP General replaced LP siding on our garage. Paul was very thorough when he came out to do the estimate; he listened to my concerns and was able to work out solutions on the spot. His crew did a great job and were very courteous. They also were careful about cleaning up (I didn’t find any nails!). Really happy with the job and can recommend GP General.”
“I highly recommend GP General Corp for siding replacement. We recently had our wood siding replaced with James Hardie lap siding, and Paul and his team did an excellent job.”

“Will they catch the damage I can’t see?”
Most siding fails because of what’s behind it — rot, failed flashing, moisture you can’t see from the curb. With 15+ years walking Snohomish County walls, we don’t guess. We probe, document, and re-engineer the wall assembly with drainable WRB, integrated flashings, and rainscreen ventilation built for Pacific Northwest weather.
Building Science First“I’m tired of high-pressure salespeople.”
No same-day discounts. No “this price is only good if you sign tonight.” We give you a free written assessment, a fixed-price contract, and the time to think it over. Most of our work in Stanwood comes from neighbor referrals — you don’t earn that doing it any other way.
No-Pressure Quotes“Will the warranty actually mean anything?”
A warranty is only as good as the install behind it. We’re a certified James Hardie installer, which means every panel goes up to manufacturer spec — gap, fastener, primer, every detail. That’s what keeps your 30-year Hardie product warranty enforceable if you ever need to use it.
Manufacturer-Backed“How do I know they won’t disappear after the check clears?”
Owner-run with 15+ years of Snohomish County siding experience behind it. WA License #GPGENGC830KD backed by a $30,000 contractor bond — both verifiable any time at L&I. You’ll work with Paul start to finish. Same person quoting, walking the job, and answering the phone in year five if a question ever comes up.

Siding Materials for Stanwood Homes
How We Do It
From permit to final walk-through, here’s exactly how a re-side in Stanwood runs with GP General Corp.
We remove the existing siding completely and inspect every square foot of sheathing before anything new goes up. On Stanwood homes we look specifically for salt-accelerated fastener corrosion on water-facing elevations and standing-water cycling at the bottom wall courses on flood-plain parcels. Any compromised sheathing is replaced with new plywood or OSB. This is where we find the hidden problems — failed flashings, missing WRB, saturated sheathing — that caused the old siding to fail in the first place.
We install Benjamin Obdyke HydroGap Drainable as our standard WRB on every job. The integrated drainage gap keeps any moisture that gets behind the siding moving down and out instead of sitting against sheathing. This matters for Stanwood because of ~48 inches annually with coastal flats flood exposure and direct saltspray from Port Susan. Seams are lapped upper-over-lower (6” horizontal, 12” vertical), taped at joints, and integrated with window and door flanges using peel-and-stick flashing.
Head flashings above windows and doors. Kick-out flashings at every roof-to-wall intersection. Step flashings along rooflines. Proper flashing integration at every penetration — vents, hose bibs, electrical boxes, light fixtures. On Stanwood jobs we give extra attention to water-table flashings on flood-zone properties and stainless-upgrade fasteners on all saltwater-exposed elevations. Failed or missing flashings are the number one cause of siding failure we see, so we upgrade these details beyond code-minimum wherever the install justifies it.
HardiePlank installed to James Hardie’s Best Practices manual for the HZ10 climate variant — the PNW-required product (HZ5 voids the warranty here). 1¼” corrosion-resistant nails, blind-nailed, ½” gap at trim, matched to your original reveal. For saltwater-facing walls we install supplemental furring behind Hardie for rainscreen drying airflow. ColorPlus pre-finish carries a 15-year color warranty; primed board gets field-painted within 180 days of install.
Every joint, butt-end, and penetration gets sealed with a high-grade elastomeric sealant rated for siding movement. Salt residue on coastal-exposure walls shortens sealant surface life — we spec marine-grade product on those elevations, so sealant selection and bead size matter — we spec for the widest cycling range each Stanwood elevation will see, not the average. Joints are tooled, not just applied, for full bond contact on both faces.
We walk the property with you at the end of the job to make sure everything looks great and you’re happy with the final result. It’s a 20-point walk: caulk lines, paint touchups, downspout reattachment, gutter reset, and site cleanup. Permit sign-off from the City of Stanwood (or Snohomish/Skagit County on unincorporated properties) is documented and handed off to you.
The Siding Issues We Fix Most in Stanwood
Port Susan is only a few miles from most of Stanwood. Salt air accelerates the breakdown of unprotected wood siding and corrodes standard fasteners. We find cedar siding near the coast failing decades earlier than identical siding installed inland. Material and fastener selection matters here.
Stanwood’s older farmhouses have often been re-sided once or twice without removing the original cladding. We find two or three layers stacked up — each one trapping moisture against the one below it. Full tear-off to the sheathing is the only way to know what you’re dealing with.
The flat agricultural land around Stanwood offers no windbreak. Wind-driven rain hits the siding horizontally, forcing water into joints that hold up fine in sheltered locations. We detail joints and flashings tighter on exposed Stanwood properties to account for this.
What Stanwood Homeowners Say
“Old farmhouse with three layers of siding. Paul’s crew tore everything off, replaced rotted sheathing, and installed Hardie. They also did the shop building. One crew, one project, clean result.”
“We’re close to the water and our cedar was falling apart after 18 years. Paul recommended Hardie for the coastal exposure. Explained exactly why. No pressure, just facts. The install was clean and on schedule.”
“Paul gave us an honest assessment. Told us the north wall needed replacement but the other three walls had years left. Saved us thousands. That kind of honesty is rare.”

Stanwood Areas We Work In
The original town core with homes from the early 1900s. Norwegian heritage community with well-maintained older homes. Wood lap siding is common — some original, some re-sided in the 1970s–1980s.
Farmhouses on larger lots surrounding the town. Many have detached shops and outbuildings. Wind exposure on the flat delta land makes flashing and joint detailing especially important.
Just across the bridge. Direct coastal exposure means salt air, higher humidity, and more aggressive moisture conditions. Corrosion-resistant fasteners and zero-absorption materials are essential here.
Low-lying properties near the river delta and coastline. Ground moisture is the primary challenge. Proper siding-to-grade clearance and WRB are non-negotiable in this area.
