There is no substitute for a local window installation contractor who actually knows Sumas. We've spent years protecting homes across Whatcom County and the Canadian border against everything the Northwest throws at them, and we treat every home like it's our own.
Great window installation starts with understanding Sumas. Our team has worked on homes throughout Whatcom County and around the Canadian border for years, and we bring that local knowledge to every project — from the first free inspection to the final cleanup of your yard.
Fixed scope and fixed price. No surprise change orders once the work begins on your Sumas home.
We protect your landscaping, clean up every day, and finish with a full magnetic nail sweep of your property.
Every material is specified for coastal wet, salt air, wind, and moss — not a generic national product line.
We hold manufacturer certifications from Milgard, Andersen, Shaw — the kind of factory-backed warranties most local window installation crews can't offer.

We're based in Whatcom County and serve Sumas plus surrounding communities including Nooksack, Everson, Lynden. If you're nearby, we're a short drive from your door.
We do. Many Sumas homeowners spread the cost of a larger project over time with flexible financing — ask about current options when you request your free estimate.
The cost depends on the size and scope of your project, the materials you choose, and the condition of what's already there. We give every Sumas homeowner a free, written, itemized estimate so there are no surprises — call us to schedule yours.
Because of our wet, mossy the Canadian border climate, longevity here can differ from drier regions. Quality Milgard materials installed to spec with proper ventilation reach the upper end of their expected life — we'll walk you through the options for your home.
