6 Best Siding Contractors in Seattle for 2026

Seattle's housing stock is a real mix. You've got Craftsman bungalows in Ballard and Wallingford with original cedar lap siding that's been through decades of Pacific Northwest rain, vinyl-clad ranches in Burien and Renton, and newer fiber cement installations going up across Beacon Hill and South Lake Union. The region's climate is the defining factor here. Sustained moisture, freeze-thaw cycles in the winter months, and the kind of wind-driven rain that cuts in from Puget Sound means siding takes a beating that it simply wouldn't in drier parts of the country. Contractors who work regularly in King County and Snohomish County know to look for water intrusion behind old wood siding, rotted sheathing around window headers, and failing caulk lines that let moisture wick into the wall assembly. If your home is older and still has the original cedar or redwood boards, there's a decent chance a full replacement will uncover rot or mold once the first panels come off. Budget for that possibility.

The businesses featured on this page were drawn from third-party public business listings and ranked by their public review rating and review count, with a small lift applied to those that show a working website and a reachable phone number. We don't just pull names from a list, though. We check each business's homepage to confirm that siding contractor work is what they primarily do, which keeps unrelated trades or general handyman services off the page. Any listing flagged as permanently closed is removed automatically and won't appear here. Where you see a Trust Verified badge next to a business name, that business has gone a step further and passed our full independent verification process, covering trade qualifications and accreditations, public liability insurance, trading history, customer review history, and registered company information. Visit our How We Verify page for the complete checklist. Businesses without that badge have not been independently verified by us.

Before you book anyone, get at least three written quotes. Siding prices in Seattle vary more than you'd expect. Fiber cement installation, say James Hardie planks, typically runs between $8 and $14 per square foot installed depending on the complexity of the job, while vinyl sits lower at around $4 to $9 per square foot and engineered wood can push above $15 per square foot on complex facades. Ask each contractor whether they're licensed with the Washington State Department of Labor and Industries, which is a legal requirement here, not a nice-to-have. Request proof of general liability insurance and, if they're bringing a crew, workers' compensation coverage too. Get the scope of work in writing before any deposit changes hands, and confirm whether the quote includes removal and disposal of the old siding or whether that's billed separately. That line item alone can add $1,000 to $3,000 to a mid-size job.
