Edmonds Siding Contractor — Bowl Homes, Waterfront, Salt-Air Expertise

Edmonds faces a double moisture attack: salt air off Puget Sound from the west and the natural bowl topography that channels rainwater downhill, keeping lower homes perpetually damp. From the historic downtown to Perrinville’s wooded lots, every Edmonds neighborhood has its own siding challenge. Paul knows them.

“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.”

Why GP General Corp

Why Edmonds Homeowners Trust Us With Their Siding

You’ve probably gotten a few quotes for Edmonds siding contractor work already. You’ve heard the pitches. Here’s what makes us different — and why Edmonds homeowners don’t shop around the next time.

Recent GP projects in the Seattle area:

01

“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
02

“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 Edmonds comes from neighbor referrals — you don’t earn that doing it any other way.

No-Pressure Quotes
03

“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
04

“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.

Installation Process

How We Do It

From permit to final walk-through, here’s exactly how a re-side in Edmonds runs with GP General Corp.

Bowl Drainage Keeps Lower Homes Wet — siding issue on Edmonds home, GP General Corp inspection
01
Tear-Off and Substrate Inspection

We remove the existing siding completely and inspect every square foot of sheathing before anything new goes up. On Edmonds homes we look specifically for salt-accelerated corrosion on west-facing nail heads and corrosion of ferrous fasteners in original sheathing. 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.

Weather resistive barrier WRB installation
02
Weather-Resistive Barrier (WRB) Installation

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 Edmonds because of ~38 inches annually, plus direct saltwater-influenced marine air on west-facing elevations. 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.

03
Flashing at Every Transition

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 Edmonds jobs we give extra attention to marine-grade fasteners at flashings (we upgrade to stainless on saltwater-exposed walls even when manufacturer min is galvanized). 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.

James Hardie ColorPlus Arctic White board installed to spec — Seattle siding contractor GP General Corp
04
Board Installation to Hardie Spec

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. Waterview walls get a WRB lap detail engineered for wind-driven saltspray rather than just rain. ColorPlus pre-finish carries a 15-year color warranty; primed board gets field-painted within 90 days of install.

Caulking and joint treatment on James Hardie siding — Seattle siding contractor GP General Corp
05
Caulking and Joint Treatment

Every joint, butt-end, and penetration gets sealed with a high-grade elastomeric sealant rated for siding movement. Sea-salt residue on west-facing walls shortens sealant surface life — we spec higher-grade sealants on those elevations, so sealant selection and bead size matter — we spec for the widest cycling range each Edmonds elevation will see, not the average. Joints are tooled, not just applied, for full bond contact on both faces.

06
Final Walk-Through

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 Edmonds (or Snohomish/Skagit County on unincorporated properties) is documented and handed off to you.

Common Problems

The Siding Issues We Fix Most in Edmonds

Salt Air Corroding Fasteners — siding issue on Edmonds home, GP General Corp inspection
Salt Air Corroding Fasteners

Homes within a mile of Puget Sound face corrosive marine conditions. Standard galvanized fasteners corrode within a few years in Edmonds’ salt air. We specify 316 stainless steel fasteners and marine-grade sealants on all coastal projects. The Kingston ferry terminal creates wind-tunnel effects downtown that drive salt deeper into neighborhoods.

Bowl Drainage Keeps Lower Homes Wet — siding issue on Edmonds home, GP General Corp inspection
Bowl Drainage Keeps Lower Homes Wet

Edmonds Bowl’s topography channels rainwater downhill. Lower-elevation homes have siding that stays damp from above and from the Sound. We see accelerated rot at the bottom courses and foundation-adjacent walls. Wider siding-to-grade clearance and proper kickout flashings are essential.

60-Year-Old Siding on 40% of Homes — siding issue on Edmonds home, GP General Corp inspection
60-Year-Old Siding on 40% of Homes

Nearly half of Edmonds was built 1940–1969. Original cedar, hardboard, and even some aluminum siding. After 60+ years of PNW marine moisture, most of it is past its useful life. The Historic Preservation Commission reviews changes in the downtown core — we prepare submissions that meet their standards.

Reviews

What Edmonds Homeowners Say

★★★★★

“West-facing wall in the Bowl was rotting at the bottom despite looking fine. Paul explained the drainage pattern and specified wider clearance at grade plus kickout flashings the original builder missed. Root cause fixed.”

Homeowner, Edmonds Bowl
★★★★★

“Our downtown Craftsman needed siding that matched the historic character. Paul worked within the Historic Preservation Commission guidelines and sourced cedar profiles that matched the original 1920s proportions.”

Homeowner, Downtown Edmonds
★★★★★

“Seaview home facing the Sound. Paul specified stainless fasteners and marine sealants without being asked — he just knew. Two other contractors quoted standard galvanized. That’s a $15,000 mistake waiting to happen.”

FAQ

Edmonds Siding Questions

Does salt air really require special fasteners?
Yes. Within a mile of Puget Sound, 316 stainless steel fasteners are required. Standard galvanized corrodes in Edmonds’ marine environment within a few years. Marine-grade sealants are also essential. We specify this on every Bowl and waterfront project.
Do I need Historic Preservation review in downtown Edmonds?
The Historic Preservation Commission reviews significant exterior changes in the downtown core. The city has conducted surveys in 2005, 2011, and 2015 documenting historic properties. We prepare submissions that meet commission standards for materials and design.
Why is the Bowl worse for siding than other Edmonds neighborhoods?
Topography. The Bowl channels rainwater downhill, keeping lower-elevation homes damp from above. Combined with Puget Sound salt air from the west, it’s a double moisture attack. Wider siding-to-grade clearance, kickout flashings, and Hardie fiber cement handle it.
What does siding cost in Edmonds?
HardiePlank with ColorPlus and marine-grade hardware: $14–$20/sq ft installed (the marine-grade fasteners and sealants add cost). Typical Edmonds home: $18,000–$38,000. Historic district projects with custom cedar trim cost more. Get a quote.
How long does a full replacement take?
Two to four weeks for most Edmonds homes. Bowl properties with steep hillside access take longer for scaffolding setup. Historic district work with custom trim details adds time. Timeline in your written quote.
What is the best time of year to install siding in Edmonds?
May through September is the best window for siding installation in Edmonds, with the driest stretch in August. Edmonds Bowl and Edmonds waterfront catch persistent fog and humidity well into October that slows caulk and primer cure, so we schedule those addresses tightly inside the dry window. Inland Edmonds (Five Corners, Maplewood) is more forgiving for shoulder-season installs. Winter work proceeds with strict dry-in protocol but lead times grow in spring as everyone competes for dry-season crews.
How much does it cost to re-side a typical Edmonds Bowl home?
A typical Edmonds Bowl home (1,800–2,800 sq ft floor area, ~2,700–4,200 sq ft of wall area) runs $38,000–$84,000 for a full re-side with James Hardie fiber cement installed. Pricing per square foot of wall area:
  • James Hardie fiber cement (with HydroGap Drainable WRB + vented rainscreen) — $14–$20/sf installed
  • Cedar or Lunawood thermally-modified wood$20–$40/sf installed
  • Hardie Artisan or standing-seam metal$30–$55/sf installed
Edmonds Bowl homes near the waterfront require salt-air-grade stainless fasteners and flashing, which adds $1,500–$3,500 to the materials line. Historic district homes with original profile-matching add another $3,000–$8,000 in custom trim labor.
Do I need a permit to replace siding in Edmonds?
The City of Edmonds does not require a permit for like-for-like residential siding replacement, but Edmonds’ Historic Preservation Commission has design review jurisdiction in the downtown district that includes any visible exterior change. Outside the historic district, like-for-like siding replacement is permit-exempt. Inside the historic district (most of downtown Edmonds), even like-for-like material changes require Historic Preservation Commission review — turnaround is 4–8 weeks. Insulation upgrades, structural framing repair, or material changes that affect fire ratings trigger a building permit anywhere in Edmonds. We confirm permit and HPC requirements on the assessment visit.
Local Knowledge

Edmonds Neighborhoods We Work In

Edmonds Bowl

The hillside descending to the waterfront. Steep lots, scaffold challenges, and the double moisture attack from above and the Sound. Lower homes get the worst of both. This is where siding material choice matters most.

Downtown & Historic District

Walkable core with Craftsman bungalows and historic commercial buildings. The Historic Preservation Commission reviews exterior changes. Original 1920s–40s cedar with ornate trim details that need period-appropriate replacement.

Seaview

Puget Sound views, established homes. Direct marine exposure on west-facing walls. Corrosion-resistant everything. Beautiful neighborhood that punishes cheap materials.

Perrinville

Wooded lots larger than surrounding areas. Homes $500K–$2.25M. Tree canopy creates shade-and-moisture trapping similar to Woodinville’s Hollywood Hill. Less salt air than the waterfront, more canopy moisture.

Meadowdale & Westgate

Family-friendly neighborhoods with beach access at Meadowdale Beach Park. Farther from the Sound, less salt air. More standard siding conditions — still PNW moisture, but without the marine component.
