About Siding Vault

Siding Vault is a James Hardie Elite® siding and window replacement contractor based in Bellingham and Anacortes, Washington, serving homeowners across Whatcom, Skagit, San Juan, Island, and Snohomish counties.

While most clients first call us for siding and window replacement, we handle the full building envelope — including framing rot repair, decking, door and roof replacement, and exterior painting — for a seamless, start-to-finish exterior transformation. From our Anacortes location near the ferry, we also serve the San Juan Islands.

A credential you can verify
James Hardie Elite® is James Hardie’s highest contractor designation — their top tier — which means our crews are trained and certified in Hardie’s specification-based installation process, not just general exterior carpentry. You don’t have to take our word for it: our profile is listed on the official James Hardie® website, and our craftsmanship has been featured on James Hardie’s own social media channels.

Who we work with
