What we do

From first measurement to final install, we take care of residential windows and exterior doors across the Sunshine Coast of British Columbia.

Renovating, replacing, or upgrading? Coastmont gets it done—clean, professional, and start to finish.

Start to finish, here’s how it works.

  • Two people standing indoors looking out a large window at a lake and forest view.

    STEP 1 - Let’s Talk and Walk the Space

    Every project kicks off with a quick message from you. From there, we set up an initial call to understand what you’re looking for. We then book a time to visit your property in person. On-site, we’ll walk through everything together, talk about styles, materials, and timelines, and make sure we understand exactly what you need.

    STEP 2 - Get a Detailed, No-Surprise Quote

    After we’ve seen the space, we take precise measurements of every window and door involved. Then we work with our trusted suppliers to put together product options that match your budget and style. You’ll get a detailed quote with specific pricing, specs, and timelines—no vague ballparks, no hidden extras. Just a clear plan for moving forward.

    STEP 3 - Professional Install, Clean Finish

    Once the products are ready, we book your install. Our team handles everything—removal of old windows, prep work, expert installation, and a full cleanup when it’s done. We leave your home looking sharp, with high-quality windows and doors installed to last. No gaps, no drafts, no headaches—just results you can feel every day.
