Welcome to Guardian Windows & Doors: Sudbury and Surrounding Areas

It’s common knowledge that the quality and age of your windows, doors and siding directly affect your home’s value and your family’s comfort. Replacing energy-wasting elements with those that keep cold air out and warm air in is not only environmentally sound, it saves you money. And it also reduces your environmental footprint. Let Guardian Windows & Doors optimize your Sudbury home. We also serve surrounding areas.

Energy Star-Rated

In business since 1996, Guardian Windows & Doors specializes in siding, window replacement, supplying and installing Energy Star-rated windows and doors in Sudbury and throughout the Rainbow Country area. Guardian Windows & Doors is proud to offer environmentally friendly Gentek Building Products, as well as free low-E (low-emissivity) glass coatings and argon gas fill to help seal in your window’s insulation for better performance.

Save Your Money

If you replaced your windows and doors and did not call Guardian Windows, you paid too much! We use the “Super Spacer System” that helps reduce sweating on glass. Ask us about the availability of government grants, which varies on a case-by-case basis, and our senior discounts.
