New Windows & Installation in Tewksbury, NJ

There’s no honest flat price, because every house is different. The number of windows, the size of each opening, the style, the brand, and the glass package all move the price, and so does any rot we find once the old frame is out. We measure every opening for free and hand you a written quote that lists each window separately.

Yes. We wrap the exterior trim around each new window in aluminum or PVC to match the house, so there’s no bare wood left to rot or paint. It gives the finished job a clean look and keeps water out of the trim.

New windows stop the drafts that come from the window itself, like worn weatherstripping, loose sashes and gaps around the frame, as long as they’re installed right. We insulate around every new window with low-expansion foam and seal it inside and out, which is where many installs fall short. Drafts from doors or outlets are a separate issue.

You get two layers of coverage. The window itself carries the manufacturer’s warranty, and Nail Force backs the installation with a written workmanship warranty. Our workmanship warranty transfers to the new owner if you sell the house. We’ll go over the details of both with you before you sign anything.

Replace it when the fix costs more than it’s worth or won’t last. Fog between the panes means the seal failed, and that can’t be cleaned out. A rotted sill or a frame that lets air through will keep getting worse. If a window just needs a new lock or fresh caulk, we’ll say so and save you the money.

Yes, every window estimate we do is free. There’s no charge for the visit, the measurements, the photos, or the itemized written quote. We’d rather you see our work on paper and decide on your own. Call (973) 713-1053 to book yours.

Each opening is measured on its own, because houses settle and openings are rarely perfectly square. Those measurements set the size for each window so it fits correctly without big gaps to fill. We take all the measurements during your free in-home estimate, so the quote matches your actual openings.

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.

They do, when they’re installed right. Better glass slows heat moving through the window, and a tight install stops air from leaking around it. Both matter. A great window installed poorly still leaks. We seal every opening with low-expansion foam and caulk inside and out.
