Your home's exterior takes a beating every single day — sun, wind, rain, impact. When siding fails, moisture gets in fast and damage follows. Forge Siding sends licensed Siding crews across Black Diamond, WA to inspect, repair, and replace with zero guesswork.
We didn't start Forge Siding to push volume — we built it because homeowners in Black Diamond kept getting burned by crews who cut corners on material selection, skipped moisture barriers, and left job sites messy. That's not how we work. Every Siding project starts with an honest assessment: we look at your substrate condition, check for existing rot or moisture intrusion, and talk through your options before a single nail goes in.
Our crews are licensed, carry full general liability and workers' comp, and every lead installer has completed manufacturer certification training. We work with fiber cement, engineered wood, vinyl, and steel systems — and we'll tell you straight which one makes the most sense for your home's structure, your local weather patterns, and your budget. No upselling, no pressure.
Siding doesn't fail overnight — it gives you warning signs first. Catch them early and a repair handles it. Miss them, and you're looking at rot, mold, and structural repairs on top of the siding bill.
Hairline cracks look cosmetic but they're water channels. Once moisture gets behind the panel and hits the housewrap — or finds no housewrap at all — sheathing rot starts within one season.
Buckling almost always means the substrate underneath has moved — often because moisture got behind the panel weeks or months ago. The panel is showing you the symptom, not the cause.
Paint peeling on your inside walls near exterior surfaces is a classic sign that moisture is migrating inward through failing siding. By the time you see it inside, the wall cavity is already compromised.
A missing panel after a wind event or impact isn't just cosmetic damage. That exposed sheathing is collecting rain until you replace it. This is one repair that can't wait for a convenient schedule.
Old or failing siding, particularly if the housewrap underneath has deteriorated, acts like a thermal short-circuit. Your HVAC runs harder to compensate, and the bills reflect it before the siding looks obviously bad.
Heavy algae or mold staining on the exterior surface isn't just cosmetic — it means the surface is retaining moisture long enough for organic growth. That moisture is also working its way into the wall system.
From a single damaged panel to a complete re-side on a large commercial property, we handle the full range of exterior cladding work — and we do it with the same crew standards regardless of job size.
Fiber cement is the workhorse material we recommend most in WA's climate — it handles humidity, impact, and UV better than most alternatives and carries manufacturer warranties that actually hold up. We're certified installers for HardiePlank, HardieShingle, and competing fiber cement systems. Installation follows manufacturer specs to the millimeter: correct lap, correct fastener type and spacing, correct clearance from grade and roof surface, and full housewrap integration on every project.
Done right, vinyl siding is durable, low-maintenance, and cost-effective. Done wrong — wrong gauge, wrong fastener pattern, no expansion clearance — it warps in the heat and pulls loose in wind. We use .044" and .046" gauge panels minimum and follow thermal expansion specs precisely for WA's temperature range. Nail hem fastening at 16" centers, 1/32" expansion gap at all trim terminations, and a fully integrated vinyl accessory system so the corners, J-channel, and window trim all work together.
LP SmartSide and similar engineered wood products split the difference between the look of real wood and the dimensional stability of manufactured products. They're primed at the factory, accept field-applied paint well, and hold up to impact and moisture better than OSB or solid wood. We use LP SmartSide Trim & Fascia alongside the panel and lap systems so the trim package matches — no mixing incompatible products that age differently.
Our repair crews use the same material standards as our full-installation teams — no caulking over gaps as a permanent fix, no missing sealant at transitions, no shortcuts on housewrap at the repair perimeter. If there's rot in the sheathing behind the damaged panel, we address it during the repair rather than covering it up.
We work with metal panel systems, large-format fiber cement, and commercial-grade vinyl for multi-family and light commercial applications. EIFS compatibility work, expansion joint detailing, and coordination with waterproofing and window subcontractors are all in scope. We carry the insurance requirements for commercial GC work and can provide certified payroll documentation for public projects.
Siding that terminates at rotted or missing fascia boards isn't protected — it's channeling water straight into the rafter tails. We routinely pair siding replacement with trim, soffit, and fascia work so the entire exterior envelope is addressed in one mobilization rather than two. PVC trim board, prefinished aluminum coil, and fiber cement fascia are all in our wheelhouse.
We built our process around the two complaints we heard from homeowners most: contractors who didn't communicate, and scopes that changed after signing. Here's exactly how a Forge Siding project runs from start to finish.
We come out, examine your existing cladding, probe for soft substrate, check flashing and housewrap condition at visible penetrations, and give you an honest assessment of what we're working with. No high-pressure sales — just a clear picture of the project scope before we talk numbers.
You receive a line-by-line written estimate: material cost by product and quantity, labor, removal and disposal of existing siding, and any sheathing repair identified in the assessment. We walk through material options with physical samples, not just catalog photos. You sign off on the spec before we order anything.
Your start date is locked at signing. Crew arrives on time, materials are staged and ready, and the site is protected before demo begins. We run a tight job — no leaving panels exposed overnight when rain is in the forecast.
At project completion, we walk the entire exterior with you. Every run of siding, every corner, every trim termination — you look at it before we close out. If anything isn't right, it gets fixed on the spot. Our goal is that you refer us to your neighbor the week after the project wraps.
We don't sub out work to unlicensed handymen to cut costs. Every installer on a Forge Siding project is a W-2 employee or licensed sub with verified credentials and completed manufacturer training.
Upfront pricing means you know what you're paying before a single panel comes off the wall. Change orders require your written approval. We've built our reputation in Black Diamond, WA on the fact that our estimates are reliable.
We run our calendar tightly so the start date we give you is the date we're there. If a legitimate delay comes up — major weather, material shortage — we call you the day before and reschedule immediately, not a week later.
Old siding demo generates a lot of debris — old panels, nails, housewrap, fasteners. We haul it out daily. Your driveway, lawn, and landscaping are clean at the end of every work day — not just at project completion.
Our workmanship warranty covers what we did and how we did it. The product carries the manufacturer's own warranty on top of ours. That means your home is protected twice — by the material the manufacturer stands behind, and by the installation Forge Siding guarantees.

We had three other quotes before calling Forge Siding. The difference was the inspection — they actually walked the whole house with a moisture meter and found soft sheathing behind two panels on the north wall that nobody else mentioned. The estimate covered the sheathing repair too, so no surprise charges when demo day came. Final result is clean and tight. We'd hire them again without hesitation.
I manage a twelve-unit building in Black Diamond and we needed LP SmartSide on three facades before winter. Forge Siding coordinated with our property manager, worked around tenant schedules, delivered materials in two staged drops to keep the lot clear, and finished four days ahead of the original schedule. Commercial billing was clean and documented. They're on our preferred vendor list now.
The fascia and soffit on our older home were rotting away and we assumed it would be a nightmare project. Forge Siding quoted it alongside the siding replacement so everything was done in one mobilization. The crew found two spots where the rafter tails had started to soften — they showed me photos before touching anything and walked me through the repair options. The whole exterior looks like a different house now.
The estimate process was refreshingly honest. The estimator told me upfront that my old OSB sheathing had delaminated in two areas and would need replacement before new siding could go on — with photos and a written line item. No one had mentioned that in the other quotes. Forge Siding fixed the sheathing, installed the HardiePanel system, and the project cost exactly what they quoted including the repair.
Five-star work across the board. The crew showed up when scheduled, worked efficiently, and the lead walked me around the house at the end of each day so I could see progress and raise any questions before the next morning. The final product is outstanding — tight lap lines, perfect miters at the corners, no nail pops. My neighbor has already asked for Forge Siding's contact information.
We had three bids and Forge Siding was the only contractor who physically checked the housewrap condition before quoting. Everyone else just looked at the surface. They found a section of torn WRB behind the garage bay that needed patching and included it in the estimate. When you're spending this much on an exterior, you want a company that checks the whole wall system, not just what they can see from the ground.
