Energy-Efficient Windows Installed by the Experts in British Columbia

Quality replacement windows from our trusted partner

We install energy-efficient windows in Saanich

When necessary we can work with you to upgrade underperforming windows in a wide variety of styles and materials.

Window replacement is not our business but it’s often apparent that old, loose, or ill-fitting windows are contributing to the energy inefficiency of the home.

Because we are dedicated to helping homeowners have more comfortable, efficient homes, we have teamed up with a window manufacturer that can provide great-looking, energy-efficient windows.

Built on the West Coast for the West Coast

We found the right partner in Modern Windows of Powell River in nearby British Columbia. Modern Windows manufactures Energy Star rated (low-E and argon gas filled) windows that are perfectly suited to our ‘wet coast’ climate and housing market. They offer more standard features, such as brass rollers and removable screens, as well as many customizable options with regard to grids, glass, opening styles and colors. In addition, Modern Windows employs its own installers, not subcontractors. It has a well-deserved reputation for prompt service and offers comprehensive warranties on its products.
