New siding is a 25-to-40-year investment — and its longevity is almost entirely determined by who installs it, not which product you chose. Missed expansion gaps, skipped housewrap laps, wrong fastener schedule: every shortcut shows up in your wall cavity long before it shows up on your surface. Our Seattle, WA installation crews are factory-certified on every cladding system we install and back every project with a written workmanship warranty.

Our Seattle, WA specialists bring the credentials, diagnostic tools, and installation expertise that make the difference between a repair that holds and one that repeats.
Certified on vinyl, fiber cement, engineered wood, and steel. Certification isn't cosmetic — it keeps material warranties in force after we leave.
Every estimate starts with an on-site measurement covering all wall planes, penetrations, and substrate conditions — the foundation of a quote you can actually rely on.
Panels, trim, housewrap, labor, permit — every component listed separately before you sign. The estimate is the contract.
A signed document specifying coverage period and resolution process. Not a verbal promise — something you can actually enforce.
Every service below is executed by our own licensed Seattle, WA crew — not passed to a subcontractor network. Certified installers, manufacturer-grade tools, and written scope on every project.

Complete demo of all existing cladding, substrate moisture inspection with a calibrated meter, housewrap replacement, and full panel system installation. Every trim component — corner posts, J-channel, soffit, fascia — included in scope, not an add-on.

We work from architectural drawings, coordinate directly with framing crews, and sequence our work to hit the construction timeline. Material staged and moisture-checked on-site before any cutting begins.

The starter strip, window rough opening flashing, and roof-wall junction flashing are where most moisture failures originate. We treat them as primary scope — self-adhering membrane at rough openings, step flashing at junctions.

Every installation includes a correctly lapped, seam-taped housewrap integrated with window flanges and sealed at all penetrations. This step separates a weather-tight wall from one that fails within two seasons.

Vented or solid vinyl soffit, aluminum-capped or fiber cement fascia, and all accessory trim installed as a unified system so every component carries the same warranty start date.

When over-cladding is viable, we use a furring-strip drainage system rather than nailing directly to existing siding — maintaining drainage and giving new panels a solid elevated nailing surface.
Our Seattle, WA team follows the same documented process on every project — so you always know what comes next.
We schedule within 24–48 hours, arrive with measuring tools and moisture meter, document all wall planes and substrate conditions, and identify any issues before building the estimate.
Every component listed separately and delivered within 24 hours. The estimate becomes the contract. Material samples presented at this meeting for product selection.
Where required in WA, we handle permit application, filing fee, and inspection scheduling. Start date confirmed in writing before materials are ordered.
Installation in correct sequence — housewrap, flashing, panels, trim. Final walkthrough by elevation. Manufacturer warranty registered in your name. Workmanship warranty document delivered at project close.
The measurement visit was more thorough than I'd expected — they probed the sheathing and found elevated moisture on the west wall before we'd even discussed a product. That diagnostic honesty told me immediately what kind of contractor this was.
Fiber cement, back-primed at every field cut, fastener schedule documented. I've seen other fiber cement installations. I know what the correct process looks like. These crews followed every step of it.
Full home re-side. They found delaminated sheathing during tear-off, called me immediately, showed me the photos, and gave me the change order price before touching anything additional.
Our Seattle-based team covers every community in our Seattle, WA service area — same licensed crews, same upfront pricing, same written warranty on every project.
