Our Story
Built by James Sampson, Still Run by the Same Family
James Sampson founded Airtight Vinyl Siding and Windows with a straightforward idea. Homeowners deserved detail-oriented construction work from a contractor who actually shows up, actually knows the trade, and actually stands behind the job once the crew packs up.
Over 30 years later, James is still the general contractor on every project, and his wife Renee still runs the office and showroom. She handles the books, coordinates estimate appointments, and is usually the first person you’ll talk to when you call. Over the years, Airtight has grown from a small local operation into one of the most trusted names for window, siding, and patio door installation in Santa Cruz, Santa Clara, and Monterey Counties.
