Frequently Asked Questions
How much does window installation cost in Concord, NH?
Costs vary by window size, material, and how many you’re replacing. A1 Pro gives you an exact number during a free estimate, not a ballpark guess over the phone.
How long does window and door installation take?
Most installations take one to two days, depending on how many openings you’re replacing. A1 Pro schedules the full job upfront so you know exactly when the work starts and when it’s done.
How do I know if I need new windows instead of repairs?
Drafts, fogged glass, stuck frames, or rising heating bills usually mean replacement makes more sense than repair. A1 Pro inspects your home for free and gives you a straight recommendation either way.
What's the difference between vinyl and wood windows?
Vinyl costs less and needs almost no maintenance. Wood offers a traditional look but requires more upkeep in NH’s climate. A1 Pro can walk you through both options before you decide.
