Replacement Windows in Westfield, NJ

It depends on how many windows you’re replacing, their sizes and styles, the brand and glass package you pick, and what we find in each opening once the old window comes out. Anyone quoting windows without measuring is guessing. We’ll measure for free and give you a written, itemized price. For a ballpark first, try our window replacement calculator.

Yes. Through our financing partner, qualified homeowners can finance their window replacement instead of paying all at once. We can talk through it at your free in-home estimate, and you can learn more on our financing page before we meet.

We measure each opening, remove the old window, and check the opening for rot, showing you anything we find before it’s covered. Then we set a sill pan and flashing, install the new window, insulate the gap with low-expansion foam, seal it inside and out, and cap the exterior trim in aluminum or PVC. We clean up and walk the job with you.

We do. Sliding windows, the kind where one sash glides sideways past the other. They’re a good fit for wide openings and spots where a window that swings out would get in the way. If your old sliders stick, jump the track, or let in drafts, we’ll replace them and seal them properly.

No charge, no obligation. We come to your home, check every window you’re worried about, measure each opening, and leave you with a written quote that breaks everything down window by window. If you’d rather think it over, that’s fine. Call (973) 713-1053 to book.

Watch for fog between the panes, drafts you can feel, sashes that won’t stay up or won’t lock, soft or rotting wood at the sill, and condensation that keeps coming back. Any one of those is worth a look. Call (973) 713-1053 and we’ll give you an honest read on every window.

Yes. We replace single windows all the time, whether it’s a cracked unit, a fogged seal, or one rotted sill. We’ll match the style and trim to the rest of the house as closely as we can. If other windows show the same problems, we’ll point them out with photos, but the decision is always yours.

Your new windows are covered two ways. The manufacturer warrants the window itself, and we put our workmanship warranty on the installation in writing. If something we installed isn’t right, you call us and we come back. The workmanship coverage transfers to the next owner if you sell.

Many homeowners go with double pane glass that has a Low-E coating and argon fill, and triple pane is available if you want more. But even the best glass can’t stop a draft if the window isn’t sealed right. That’s why we foam-insulate and seal every unit inside and out. Ask us which package fits your house.
