At MBA Exteriors, we specialize in window replacement and installation in Seattle designed to handle the Pacific Northwest’s rain, wind, and seasonal temperature swings. Our premium, high-efficiency windows improve comfort, reduce utility bills, and elevate curb appeal — all backed by certified installation and a lifetime warranty.
Upgrading to energy-efficient windows will provide a number of benefits. In addition there are significant tax incentives for weather efficient windows that can put thousands of dollars back in your pocket. Our windows are built to last in Seattle’s wet climate. We carry the latest high-efficiency double and triple pane windows in a full range of styles and colors.
Older windows are typically the coldest surface in the room resulting in moisture, condensation, and potential mold in bedrooms and bathrooms. When your windows are better insulated, your home is better able to maintain a consistent temperature throughout making a more comfortable home. New windows can save 20%-30% in heating bills. With energy prices increasing coupled with improved resale value, a window project can pay off in 10 years.

Drafts and higher heating costs
