Gemini Window Services works out of 787 Boston Rd in Billerica, and takes its trade from its name — windows. The Blue Book and BuildZoom both carry a listing for the company. If you're replacing or repairing windows around Billerica, ask for a written scope with a price per opening and a firm install date, and confirm the company's Massachusetts home improvement contractor registration and liability insurance before the first pane comes out.
