Air-Tight, Water-Tight Frame Design

How would you like to expand, contract, implode, and explode windows? That's what happens when independent testers evaluate windows to meet Massachusetts' minimum standards. Some manufacturers tell the lab to stop the test when the minimum standard is met; we told them to keep going. How much did our frame withstand? Almost three times the minimum.

Maybe you'll never need that much protection. But every time a weather front passes through, atmospheric changes affect the performance of your windows and doors. Think about how much the weather changes in New England - the Great Outdoors can be tough on your Great Indoors.

Quality Materials, Quality Workmanship

The last thing you want to do after you put in new windows is turn around a few years later and find out they need to be replaced again. That's why it's important to install well-engineered frames built from high caliber materials. We use lineals made of heavy ‘virgin vinyl’ resins, sheared with equipment that ensures exact measurements and welded using today's most accurate multi-point welders. We want to be sure our materials and workmanship hold up to the ultimate test: the test of time.

Moving Parts That Don't Wear Out

Moving parts must be built to withstand a lot of wear and tear - which is why they're the second most expensive component in windows. With our years in the business, we know not to skimp. Our expertise assures our customers they're getting the best components available.

Freedom From Painting

We probably don't have to tell you that the most time consuming and expensive part of painting your home is doing the window sash and trim. Aren't you sorry to hear that expense will be gone forever when you install our window replacements, including bay windows, casement windows, and double hung windows?

We offer every shape and style of window you could want, so you don't have to compromise when it comes to looks.  Elements Windows come in a wide variety of styles, including bay windows, bow windows, casement windows, and double hung windows.  Sliders and special shapes are also available.  Unique trademark products in the Elements line include the Garden Vue™ garden window, Thermal Glide™ sliding patio doors, and Bellemeade™ French patio doors.
