FAQ

Choosing a window & door company: straight answers.

What Massachusetts homeowners ask before they pick a company, answered plainly.

Cost

It depends on your home. Price is figured from the number and size of openings, the window style (a bow costs more than a double-hung), the glass package you pick, interior color or finish, and whether an opening needs insert or full-frame work. We measure every opening at a free in-home estimate and give you a clear written price.

Yes, it’s free. We look at your windows and doors, show you real options, and give you a straight price. There’s no cost and no pressure.

Compare the same scope: the number of openings, the glass package, insert or full-frame install, what the written coverage includes (parts, labor, how long, whether it transfers), and the company’s license and insurance. Ask for everything in writing.

Process

Windows are made to measure, so we schedule your install date once they’re ready. Most jobs finish in one day. We give you a date and keep it.

Yes. We pull the building permit for window and door installs; storm-door-only jobs don’t need one.

We protect the work area, clean up and do a walkthrough before we leave.

Most of our work is insert replacement: we set the new vinyl window into the existing frame and keep your interior and exterior trim. If a frame is rotted, we’ll tell you and recommend full-frame for that opening.
