Why Choose Trust Build Windows and Doors in St. Thomas
Built for St. Thomas weather & exposure
Open subdivisions west and south of town and lake-effect gusts from the Lake Erie side stress weak frames. Our energy-efficient windows St. Thomas pair Low-E tuned for glare reduction, argon fill, warm-edge spacers to fight condensation, and rigid frames that stay square through freeze–thaw—perfect for homes near Dalewood Reservoir, Lake Margaret, and wind-exposed pockets along Sunset and Fairview.
Precision fit across classic and new builds
Century homes around Talbot/Walnut and the Courthouse district, post-war bungalows off First Ave and Elm, and new builds in Shaw Valley, Harvest Run, and Miller’s Pond don’t share jamb depths or casing profiles. We laser-measure each opening, size jamb extensions/brickmoulds correctly, and match interior casings so your window replacement St. Thomas looks “built-with-the-home”—no oversized caulk joints or wavy lines.
Clean job sites, predictable timelines
We protect floors, stage materials neatly, and remove debris daily. Most 6–12 opening St. Thomas projects finish in 1–2 days with crisp interior/exterior sealing and a thorough walkthrough. Expect smooth hardware, airtight performance, and paint-ready lines—without the mess.
Financing that fits real life
Begin with zero deposit and choose 12-month interest-free (open payments). Whole-home upgrades and bundled door installation St. Thomas projects can use extended terms.

Ray and Vito sold me a new, fairly large sized door. Ray was very patient with us throughout the entire process, he answered all our questions promptly and even told us how we could save some money. Vito worked very clean and efficient, he was pleasant to deal with, and showed up on time for the installation. Very professional company and I highly recommend.
Thanks to Sergei, he well explained how the process of installing windows, patio door, storm door and provided advice so that I can easily understand what the scene will look like after replacing the windows. Also thanks to the team, while they install, they keep it very clean which save us lots of cleaning time.
