When your siding fails, it doesn't fail quietly. Moisture gets into sheathing, energy costs climb, and the interior damage that follows is always more expensive than the exterior repair that would have stopped it. Forge Siding puts licensed, manufacturer-certified crews on your Vashon property — crews who diagnose the actual problem, price it in writing, and fix it once.

What makes our Vashon operation different isn't a slogan. It's the fact that every estimate we write is line-item detailed, every project has a named lead installer accountable for the outcome, and every completed job closes with a written workmanship warranty you can actually enforce.
We work across the full project range: single-panel storm repairs, complete whole-home re-siding, new construction cladding alongside general contractors, and commercial multi-family projects for property managers who need consistent quality and documentation across multiple buildings.
Every Forge Siding project closes with a signed workmanship warranty document. Not a verbal commitment — an actual document with coverage period, covered defects, and a resolution process you can hold us to. Manufacturer material warranties are registered in your name at project completion, so the coverage that came with the product stays in force.

These are the signals that experienced crews look for on every Vashon, WA property inspection. Missing them is how a $400 repair becomes a $4,000 wall reconstruction.
Hairline fractures look cosmetic. At arm's reach they look different — especially on fiber cement where surface spalling around impact points creates moisture entry that accelerates sheathing damage.
Interior moisture near windows is frequently misdiagnosed as a window problem. Failed flashing or caulk at the rough opening — a siding-system issue — is the actual source in the majority of cases we diagnose in WA.
Buckled vinyl means panels were installed too tight for the thermal range — no expansion room for seasonal movement. The deformation grows with each heat cycle and eventually opens the panel lock, creating wind and water entry points.
On fiber cement specifically, field cuts that weren't back-primed at installation are the entry point. The paint fails at cut edges first and the pattern makes the cause obvious to anyone who's diagnosed it before.
Dark streaking from nailhead locations on vinyl or fiber cement means non-galvanized fasteners are corroding. As the fastener degrades, its holding strength decreases — a panel secured by a corroded nail is a panel waiting to separate in a windstorm.
Wall air leakage through siding failures can account for 10–20% of annual HVAC energy consumption. Addressing the envelope often produces measurable utility savings alongside the repair value.
Our Vashon, WA team handles the full spectrum of residential and commercial cladding work from single-panel storm repairs to complete building envelope re-siding on large multi-family properties.
New siding installation covers the complete scope: housewrap, flashing at all penetrations, panel installation per manufacturer specification, and finishing trim at corners, windows, doors, and the roofline. We work on new construction alongside general contractors and handle full tear-off replacements on existing Vashon, WA homes and commercial properties. Our crews are certified on vinyl, fiber cement, engineered wood, and steel panel systems — with the documentation to keep every material warranty in force.
We also handle the complete trim system: corner posts, J-channel, soffit panels, fascia wrap, and all penetration accessories. Not as an optional add-on — as part of every installation scope, because a new siding system that terminates into failing trim defeats the purpose of the project.

Root cause diagnosis before any repair work is our standing process. A cracked panel that gets swapped without investigating the housewrap beneath, a caulk joint that gets re-sealed without checking sheathing moisture — these are surface patches over active problems. We find the cause first, quote the actual fix in writing, and then execute.
For insurance-related damage, we produce a panel-level photo documentation package — close-range images by elevation, written damage scope, and material specifications formatted for adjuster review. After the initial adjuster estimate comes in lower than the actual scope, our documentation has supported successful appeals on a significant number of Vashon, WA claims. That documentation service is included in every storm inspection at no additional charge.

Each cladding material has distinct installation requirements that determine whether it performs for 10 years or 40. Our Vashon, WA crews hold certifications specific to the products they install — not one generic approach applied to every material. Fiber cement installation requires back-priming at every field cut, hot-dipped galvanized or stainless fasteners, documented fastener schedules per the manufacturer guide, and silica dust controls during cutting operations. Vinyl installation requires expansion gaps calibrated to the local temperature range in WA. Wood siding requires moisture content verification at delivery, species-appropriate nailing patterns, and end-grain sealing at every butt joint. We address each of these requirements as non-negotiable installation practice.
Beyond installation, we perform professional siding inspections — pre-purchase assessments for buyers, post-storm condition reports for insurance claims, and annual maintenance inspections for property owners who want to catch caulk failures and minor fastener movement before they become moisture damage. These inspections use calibrated pin-type and non-invasive capacitance meters for moisture assessment — tools a general home inspector doesn't carry. The written report you receive ranks deficiencies by priority and includes rough cost ranges for every item.

Vinyl soffit and fascia wrap, HardieTrim boards, aluminum-capped fascia, and fiber cement trim boards are all within our scope. On replacement projects, we replace trim components that are damaged or compromised regardless of the primary panel material — because leaving failing trim behind a new siding installation creates the exact moisture entry point the new siding was supposed to eliminate.

Post-storm inspections document hail and wind damage at panel face level — the close-range evidence that insurance adjusters need for full-scope claim approvals. We've helped Vashon, WA property owners recover claim settlements that significantly exceeded initial adjuster estimates by providing specific, photo-verifiable panel-count documentation rather than general damage descriptions.

Property managers and HOA boards working with us get a dedicated project point of contact, building-by-building scheduling documentation, and a close-out package — permit records, warranty registrations, per-building photos — formatted for board records and institutional property management systems.

These aren't aspirational claims. They're the operational standards our Vashon, WA clients reference when they send us referrals. Each one is documented and verifiable.
Materials, labor, permit fees, and disposal listed separately on every estimate. You know exactly what you're paying for before signing. The estimate becomes the contract, and the final invoice reflects it — no lump-sum numbers we can pad quietly.
We don't schedule jobs we can't start within a reasonable window. Current backlog means a delay? We tell you upfront with realistic dates, not optimistic ones designed to close the sale.
Our WA contractor license number is provided at first contact. Two minutes in the state database tells you our status, our classification, and our disciplinary history. GL and workers' comp certificates are available before work starts — not expired documents or certificates for a different company name.
We also deliver a complete close-out package: permit records, manufacturer warranty registrations, and post-project photos organized by elevation. That file is useful for insurance renewals, property sales, and HOA records long after the project ends.
Staging tarps protect landscaping and driveways before demo starts. We sweep for fasteners every afternoon before the crew leaves. Debris is hauled off-site rather than sitting in a roll-off on your driveway for three weeks after the project ends.
You don't have to call us to find out where your project stands. We tell you, every day, in writing.
The same documented process governs every project we take in Vashon, WA. No mystery, no moving goalposts — you know what's happening at every stage.
You get a real conversation with a dispatcher who knows the product — not a scheduling app that drops your request into a queue. The site assessment is diagnostic, not just a measuring visit.
Delivered within 24 hours of the site visit. Every component — panels, trim, housewrap, fasteners, labor, permit fee — listed separately. We bring material samples to the estimate meeting and walk through the product trade-offs relevant to your Vashon, WA property.
Where permits are required in WA, we handle the application, filing fee, and inspection scheduling as part of standard scope. Your confirmed start date is in writing and the crew assignment is confirmed before materials are ordered.
Morning update from the lead installer confirming the day's scope. Afternoon update reporting what was completed. Unexpected substrate conditions documented same-day with photos and a written change order — never added to the invoice without prior approval.
Close-out package delivered: permit records, manufacturer warranty registrations in your name, post-project photos by elevation, and our signed workmanship warranty document. Everything in one organized file.
Full replacement, line-item estimate, project finished on schedule, and a close-out package with every warranty document organized before I signed off on final payment. This is what a professional siding project actually looks like.
The insurance documentation package they produced — panel-by-panel photos, written damage scope by elevation — got our claim approved at full replacement on first review. The adjuster told us it was the most detailed storm documentation he'd seen that year.
We manage a 34-unit townhome community. The per-building documentation, the building-by-building scheduling, the HOA board close-out package — these are things I'd been trying to get from contractors for years and never received until Forge Siding.
They found rotted sheathing on the west wall during tear-off. Called me within the hour, showed me the photos, issued a change order before doing anything. That's the process working exactly as it should — and it's shockingly rare in my experience with contractors.
The daily morning and afternoon updates from the lead installer were something I hadn't expected. I always knew exactly where the project stood. When the permit inspection happened, I heard about it the same day it passed.
Site was clean every evening — tarps on the landscaping, fasteners swept, no debris left overnight. On the last day of the project, the yard looked better than when they'd arrived. That's a detail that matters.
Proximity matters for response time and for practical accountability. Our Vashon crews work in Vashon, WA communities year-round, building the inspector relationships, material supplier reliability, and local code familiarity that produce better project outcomes than out-of-market operations working from a generic spec sheet.
