Our Story

Started by a Local Contractor

James Sampson started Airtight Vinyl Siding & Windows over 30 years ago with a simple idea. Homeowners deserved a contractor who actually shows up, actually knows what they’re talking about, and actually stands behind the work after the crew drives away.

Three decades later, that idea hasn’t changed. We’re still based out of Soquel. We still use our own crews instead of rotating subcontractors. And we still measure success by how many of our customers refer us to their neighbors, which happens to be about 7 out of every 10 jobs we do.

30 Years of Doing This the Same Honest Way

  • Early 1990s

    James Sampson Starts Airtight, a small, owner-operated window and siding contractor serving Santa Cruz County homeowners directly, with no franchise fees and no corporate ownership.

  • Building the Reputation

    Growth through word of mouth. Rather than relying on heavy advertising, the business grew almost entirely on referrals from satisfied homeowners across Capitola, Aptos, Soquel, and Scotts Valley.

  • Becoming Certified

    Airtight became a certified installer for Anlin windows and doors, CertainTeed Celect siding, and CraneBoard solid-core siding, aligning with manufacturers who build specifically for California conditions.

  • Today

    Still locally owned, still Licensed, still here. Over 30 years later, Airtight remains a licensed (CA #681507), family-run contractor based in Soquel, serving Santa Cruz and Monterey Counties with the same crew-based, no-subcontractor model it started with.
