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 Seattle property — crews who diagnose the actual problem, price it in writing, and fix it once.

What makes our Seattle 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.
We've completed projects in every climate zone Seattle, WA presents — high-humidity coastal exposures, high-altitude freeze-thaw cycling, urban heat island conditions. That geographic breadth translates to practical knowledge about product selection and installation specification that out-of-market contractors working from a generic spec sheet simply don't have.

Most siding failures start as small, quiet problems. Catching them before they reach your wall cavity changes the repair scope dramatically — and the cost even more so.
Any crack through the panel face is an active moisture entry point. Window corners and butt joints are the highest-risk locations — and the easiest to overlook until they've allowed a full season of water infiltration.
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.
Warped wood siding typically means unpainted back faces — differential expansion between the painted front and the raw back causes curvature that worsens with every moisture cycle.
Exterior paint failing within two to four years of application on wood or fiber cement is almost always a back-priming failure — moisture migrates through the panel from behind and pushes the front paint off. Re-painting without addressing this repeats the cycle.
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.
A compromised siding system — failed housewrap, open panel joints, missed penetration caulk — creates air infiltration that significantly increases HVAC load. If your heating or cooling costs have climbed without obvious explanation, the building envelope is a legitimate first suspect.
Our Seattle, 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.
Installation quality is the variable that separates a 15-year siding job from a 35-year one. The correct expansion gap for your WA climate, the proper back-priming of fiber cement field cuts, the housewrap integration at rough openings — these details determine long-term performance and they aren't optional on our projects.
For full replacement projects, our tear-off process includes substrate inspection with a calibrated moisture meter on every exposed wall section. Sheathing damage found during demo is documented with photos and priced in a written change order before any additional work proceeds — not discovered on the final invoice.

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.
Emergency dispatch for genuine siding emergencies — missing panels with rain incoming, active moisture entry into a wall cavity, structural damage — is available around the clock. A live dispatcher answers, not an answering queue. We triage by exposure severity and send a crew based on actual risk.

Each cladding material has distinct installation requirements that determine whether it performs for 10 years or 40. Our Seattle, 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.
For commercial and multi-family projects in WA, our operation extends to HOA communities, property management portfolios, and new construction cladding for GCs who need a reliable siding subcontractor with documented quality control. Standardized per-building documentation and a single project point of contact make multi-unit work manageable for property managers.

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 Seattle, 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 Seattle, WA clients reference when they send us referrals. Each one is documented and verifiable.
Lump-sum estimates are the contractor's tool. Line-item estimates are the client's. We provide the latter on every project, from a single-panel repair to a full commercial re-siding contract.
Our WA crews operate from locally based dispatch — not a regional hub routing jobs to whoever's available statewide. That means faster arrival windows, familiarity with local building departments, and crews who know Seattle's specific code requirements.
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 Seattle, 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.
The estimate is a document, not a handshake. It becomes the contract, and every line item is visible before you sign. No lump-sum number to parse after the fact.
Material is ordered against the confirmed schedule. We don't stage material before it's needed and we don't start jobs with missing material. Your crew arrives on day one with everything they need.
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.
We walk every elevation with you at project completion. Every scope item verified complete. If anything isn't right, we note it and fix it before considering the project closed. Final payment collected after the walkthrough sign-off — not before.
The moisture meter reading at the estimate visit — before we'd agreed to anything — flagged elevated sheathing moisture behind our north wall. That diagnostic step upfront told me immediately what kind of contractor I was dealing with. The rest of the project matched that first impression exactly.
Overnight storm, eight panels blown off the north wall. Called at 5:45 AM. Someone actually answered. Crew on-site by 9:30, matching panels installed, wall complete before noon. I'll never use another contractor for anything on this house's exterior.
Pre-purchase inspection on a property we were evaluating found sheathing moisture on two elevations the general home inspector had completely missed. Used the written report to negotiate a $12,000 seller credit. The inspection paid for itself about 40 times over.
I verified the license number in the WA database before signing. Current, properly classified, no history. That two-minute check was the most useful thing I did in the entire contractor selection process.
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.
Three bids — two lump sums and one line-item breakdown from Forge Siding. The line-item document made comparison possible in a way the other two bids didn't. When the choice becomes that clear, the decision is easy.
