About Us
Residential Window & Door Experts on the Sunshine Coast
Built on 30 Years of Window Expertise
We specialize in full-service residential window and door installations across the Sunshine Coast of British Columbia.
Founded by Ken Montgomery—a structural engineering graduate from BCIT with over three decades of hands-on experience—our company exists to make the process simple: measure, source, and install, all in one smooth operation.
We’re not a big-box supplier. We’re a tight crew of skilled professionals who know how to get the job done right—the first time.
The Only Full-Service Window Team on The Coast
Most window companies stop at supply. But we go all the way. Coastmont is the only company on the Sunshine Coast offering start-to-finish residential window and door solutions. From the first measurement to the final install, we handle every step—so you don’t have to juggle trades or guess who to call.
Whether you’re planning a full home renovation, replacing aging windows, or building a custom home, we’re the trusted partner for homeowners who want it done right.
Custom Solutions for Every Home
We’re your go-to experts on window and door replacements during home renovations and remodels. Every project starts with precision measurements and ends with clean, professional installation.
We source windows from three top Canadian suppliers—Centra, Vinyltek, and Jeld-Wen—giving you flexible options in quality and budget. Some packages even include a lifetime warranty.
We cover the full Sunshine Coast, and we’ll even hop a ferry or barge for nearby island projects (yes, there’s an upcharge, but we like to keep it reasonable).
