Windows in Andover, MA

Replacing windows on an Andover home means choosing units that handle New England winters, meet the town's building code, and fit the style of your house, whether it is a center-entrance colonial or a mid-century ranch. Below is what the job involves on a typical Andover property, from the first measurement to the final walk-through.

What window replacement involves on an Andover house

Most Andover houses we work on have wood framing and original window openings that have settled over decades. We check the condition of the framing, sill and exterior trim at the rough opening before recommending one of two approaches.

• Full-frame replacement removes the old window, casing and trim down to the studs. We install a new-construction window with an integrated nailing fin, flash the opening with tape, and replace the interior and exterior trim. We recommend this when the existing framing has rot, when you are changing the window size, or when we are replacing the siding at the same time.
• Insert windows fit inside the existing frame when it is sound. We remove the old sashes and stops, set the new unit in the opening, and insulate the gap with low-expansion foam. The interior trim stays in place, and we cap the exterior wood trim with aluminum bent to fit, in a color that matches the new window. Inserts keep the interior trim and disturb less of the house when the surrounding wall is in good shape.
• We air-seal every window we install. We foam the perimeter between the window and the framing, which stops drafts and keeps the wall cavity insulation performing as it should through Andover winters.
• On houses built before 1978 we follow Massachusetts lead-safe renovation rules. We contain the work area, use HEPA filtration, and clean up the work area before we leave each day. You get the lead-safe paperwork the rules require.

Window types and frame materials that work in this climate

Double-hung windows suit most Andover houses because they match colonials and capes and are easy to clean from inside. Casements seal tightly against wind-driven rain, picture windows work where you want light over operation, and bay or bow units fit living rooms and porches. We install Harvey vinyl windows and Andersen wood and Fibrex composite windows.

For Massachusetts winters, we recommend low-E glass with argon fill and warm-edge spacers. These cut heat loss and limit condensation. On vinyl frames, fusion-welded corners hold up better than mechanically fastened ones through freeze-thaw cycles.

How a window project runs from measurement to walk-through

We start with a free visit to your home. Your project manager measures every opening, checks the existing frames for rot, and talks through what you want to solve: drafts, sticking sashes, fogged glass, or just an outdated look. That site check shapes the written proposal you receive a few days later. It lists the exact window models, frame material, glass package, grid pattern, and color so the order matches what you approved.

• We apply for the building permit from the Town of Andover and schedule the rough inspection that the code requires.
• Our crew arrives with the ordered windows, drop cloths, and lead-safe containment if your house was built before 1978.
• Each old unit comes out, the opening gets inspected for hidden rot, and the new window goes in with shims, fasteners, and low-expansion foam at the perimeter.
• Exterior trim is wrapped in bent aluminum capping, and interior stops and casing are reinstalled or replaced as agreed in the proposal.
• At the end of each day the crew sweeps the rooms, gathers debris, and keeps the driveway clear.
• Once the inspector signs off, we walk the finished job with you, operate every window together, and confirm the locks, screens, and cleanup meet your expectations.
