Window Replacement NJ

There's no single number because the price is driven by how many windows, the style and material, the glass package, and whether it's an insert or full-frame install. What we can promise is the process: the quote is free, usually by phone and in person for bigger jobs; it comes line by line in writing; and nothing is ordered or removed until you approve it. Multi-window projects batch to keep the per-window price down.

Most insert replacements run about 30–45 minutes per opening once the units are on hand, so a typical whole-house job is one to a few days depending on count. Full-frame replacement takes longer per window because of the tear-out, flashing, insulation, and trim. We schedule around your day and work opening-by-opening so the house is never left wide open.

Crew arrives, floors and furniture get covered, and we work one opening at a time so the house is never standing open. Old sash out, opening checked and flashed, new unit set plumb and square, fastened to spec, then interior and exterior trim and a full cleanup before we leave. We walk through every stage in our guide to what install day actually looks like, including what to move and where we need access.

Only if the opening or its framing changes. Replacing windows in their existing openings — insert or full-frame, one window or the whole house — is ordinary maintenance under N.J.A.C. 5:23-2.7(c)1v and needs no construction permit; enlarging an opening (for example, cutting in a larger egress unit), moving one, cutting a new one or altering the framing does, and a replacement egress window cannot come back smaller in required height, width or net clear opening than the one it replaces. When your job needs a permit, we pull it under our state registration and coordinate the inspection so you don't have to file with the township yourself.

Replacement (insert) windows are built to drop into an existing frame with the wall finishes left intact — the right call for a straight swap. New-construction windows have a nailing fin and go in when the wall is open (an addition, a resized opening, or down-to-studs work). We install both and tell you which your project actually calls for.

We install across all 21 New Jersey counties from our Garfield shop, and quotes are free, usually by phone and in person for bigger jobs. Tell us your town when you call and we'll give you a realistic timeline.

If the frame and sash are sound and only one part has failed — a fogged sealed unit, a snapped balance, a worn crank — a repair costs a fraction of replacement and is the honest answer. Replacement makes sense when frames are rotted, units are single-pane or badly drafty, or you want a whole-house efficiency upgrade. See our window repair hub if a fix is what you need, and we'll tell you honestly which case you're in.
