How much does a sliding glass door cost to replace?
Typical ranges, repair vs. replace, and what to look for in a new patio door.

Short answer: about 90 minutes at your home, a look at your attic, windows and doors, measurements, a product demo, and a written plan you keep, whether or not you hire us. No pressure, no “today only” price.
You request an assessment online or call us, and we find a time that works. It helps to have a recent electric bill handy and a list of the rooms that bother you most, such as a hot upstairs bedroom or a drafty front door.
Our assessment focuses on the attic, windows and doors. It isn't a home inspection, and we don't service HVAC equipment. If we notice something outside our work, like leaky ductwork, we'll tell you and suggest who to call.
Take your time. The plan is yours to keep. If you decide to move forward, we schedule the work, manage the installers and do a final walk-through with you. Want a rough idea first? Try our savings calculator.
