Snohomish Siding Contractor — Historic District, Farmhouse, Custom Profiles
Snohomish’s Historic District earned the National Register in 1974. Queen Anne Victorians, Craftsman bungalows, Gothic Revival — homes dating to the 1860s with original wood siding, ornate trim, and profiles you can’t buy at a lumber yard. Outside the historic core, newer subdivisions ring the town. We handle both, but the old stuff is where we really earn it.
What Homeowners Say
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 Snohomish 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 Snohomish Homes
How We Do It
From permit to final walk-through, here’s exactly how a re-side in Snohomish runs with GP General Corp.

We remove the existing siding completely and inspect every square foot of sheathing before anything new goes up. On Snohomish homes we look specifically for long-cycle moisture damage at the bottom courses on river-adjacent homes, and hand-hewn sheathing variations on homes in the Historic District. 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 Snohomish because of ~42 inches annually, with Snohomish River valley flood exposure on low-lying parcels. 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 Snohomish jobs we give extra attention to water-table flashings above the foundation on flood-zone-adjacent properties get scrutinized more closely than on upland jobs. 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 Historic District homes we preserve original corner-board and cornice detailing, reinstalling restored millwork over new HardiePlank. 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. Wider joint-movement range on the heavier seasonal humidity swing in the river valley, so sealant selection and bead size matter — we spec for the widest cycling range each Snohomish 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 Snohomish (or Snohomish/Skagit County on unincorporated properties) is documented and handed off to you.
The Siding Issues We Fix Most in Snohomish

The Snohomish River crested at 34.15 feet in December 2025, breaking the 1990 record. Homes in the historic downtown and river-adjacent properties sustained water damage to lower siding courses. If your siding was in the flood zone, the bottom courses need inspection even if they look dry — moisture may have wicked into the substrate.

Victorian and Queen Anne homes have siding profiles — wider, thicker, with specific bevel cuts — that modern lumber yards don’t carry. Previous owners sometimes patched with wrong-dimension boards, creating visible mismatches. We source custom-milled profiles from local mills.

The Snohomish River valley creates persistent ground-level moisture. Homes near the river have higher water tables and dampness at the siding-to-grade interface. Proper clearance between siding and grade, plus weather-resistive barriers, are essential for any siding material.
What Snohomish Homeowners Say
“1895 Victorian with original wood siding. Paul found the right mill for custom profiles that matched the original proportions. The Design Review Board approved it immediately. No one else even knew where to source the right material.”
“Our newer home on the north end had standard Hardie work. Paul’s crew was professional, documented everything, and the 30-year warranty is registered. Simple, well-executed.”
“After the December 2025 flooding, our river-adjacent home needed the bottom two courses of siding replaced. Paul checked for moisture wicking into the substrate above the visible waterline. Found damage 18 inches higher than the flood mark. Caught it early.”
