Andover homes span nearly every era of residential construction — from the brick and clapboard houses of Shawsheen Village to postwar subdivisions throughout South Andover and newer developments near the Merrimack College area. Each comes with different window conditions, and each needs a different approach.

Andover has one of the widest ranges of housing ages on the North Shore — from 18th-century homes near the town center to 1970s colonials in Shawsheen Heights and newer construction off River Road. Each generation of home presents different window challenges: original wood frames that have rotted through, 1990s builder-grade vinyl with fogged glass and failed seals, or aluminum-clad units that are drafty and past their insulating life.
It depends on the number of windows, frame material, glass package, and whether you need full-frame or insert replacement. Most whole-house window projects in Andover range from $25,000 to $65,000+. Individual windows typically run $800 to $2,500+ installed depending on size and brand. We provide a detailed written estimate after measuring every opening.
We carry Andersen, Marvin, Pella, Harvey, and Mathews Brothers. Each brand has strengths for different applications — Andersen and Marvin for premium wood-interior and fiberglass options, Pella for a range of price points with strong performance, Harvey and Mathews Brothers for quality vinyl at a competitive price. We help you choose based on your home’s style, budget, and energy goals.
We inspect the existing frames during the estimate. If the wood frame is rotted, water-damaged, or out of square, full-frame replacement is the right approach — we remove everything down to the rough opening and start fresh with new flashing and a properly prepared opening. If the existing frame is solid and the interior trim is in good condition, an insert fits new glass and sash into the existing frame, which is faster and less disruptive.
Yes — especially if you’re replacing single-pane or older double-pane units with failed seals. Modern windows with low-E coatings, argon gas fills, and proper weatherstripping significantly reduce heat loss in winter and heat gain in summer. Many Andover homes from the 1960s through 1980s still have their original builder-grade windows that are well past their insulating life.
Massachusetts building code requires permits for window replacement when you’re changing the size, location, or structural framing of an opening. Like-for-like replacements in existing openings typically don’t require permits but must still meet current energy code. Homes in the Ballardvale Historic District may need additional review from the Historic District Commission. We handle all permitting when required.
Most whole-house projects take 2–5 days of on-site installation depending on the number of windows and complexity. Lead times for window manufacturing can add 4–8 weeks before installation begins, depending on the brand and configuration ordered. Your project manager provides a clear timeline once windows are ordered.
