Window Replacement

A new window can only perform as well as it’s installed. That’s why our replacement process includes a sill pan, flashing, low-expansion foam and sealant on every unit. You get a written workmanship warranty on the install and the manufacturer’s warranty on the window itself.

The Window Contractor Clark Can Count On

No fluff. Just what you can count on.

Five-Star Rated

Read our Google reviews and see what homeowners say about working with us. Then compare that with anyone else you’re calling for a quote.

Rot Shown First

If we find rot once the old window is out, you see it before anything is covered, and how it’s handled is put in writing.

Final Walkthrough

Before we call it done, you open, close and lock every new window with us right there. If something isn’t right, we deal with it.

Written Warranty

Your installation is covered by our written workmanship warranty, on top of the manufacturer’s warranty that comes with the window itself.

Measured Per Opening

Every window is measured on its own. Houses settle and openings vary, and guessing sizes is how you end up with gaps and drafts.

Trim Capped to Match

We wrap the exterior window trim in aluminum or PVC capping to match the house, so there’s no bare wood left to paint or rot.

How to Choose a Window Installer Near Clark

Watch how they measure. A careful window installer in Clark measures every opening individually instead of eyeballing a few and assuming the rest match. Ask what they do when the old window comes out and the sill is soft. Ask whether the new window gets a sill pan and flashing. Ask how it’s sealed, inside and out. Good contractors answer those questions easily. Vague answers usually mean corners get cut in the places you’ll never see once the trim goes back on.

That’s the standard we hold ourselves to on every window in Clark. Licensed and insured, five-star rated on Google, and a written workmanship warranty that transfers if you sell. Put us on your list and call (973) 713-1053.

What Clark Homeowners Ask About New Windows

Honest answers about windows, pricing and installation.

What should I budget for window replacement in Clark?∨

The price is driven by a handful of things: the number of windows, their size and style, the brand (we install ProVia, Andersen, Pella and Marvin), the glass package, and any rot or trim work. The best way to get a real number is a free in-home estimate. You can also get a rough idea with our window cost calculator.

How do you install replacement windows in Clark?∨

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.

What is Low-E glass and do I need it in Clark?∨

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.

Is your window warranty transferable if I sell my Clark home?∨

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.

Which window installer in Clark has the best reviews?∨

Pick the contractor who can show you proof of licensing and insurance, gives you a detailed written quote, and explains the install step by step. Reviews help too. We’re a licensed and insured window contractor, five-star rated on Google, and we’ll give you a free estimate so you can judge us yourself.

What happens at a free window estimate in Clark?∨

Yes. We’ll come to your home, look at the windows you’re concerned about, measure each opening, and give you a written, itemized quote at no cost and with no obligation. You’ll also get photos of any problems we find along the way. Call (973) 713-1053 to set it up.

Can I pay for replacement windows in monthly payments?∨

Yes. Qualified homeowners can finance their windows through our financing partner, so you can replace the worst windows now instead of waiting. We’ll explain how it works at your free estimate, or you can read more on our financing page.

Do you haul away the old windows?∨

Yes. Every old window, all the trim we remove, and the job debris leaves with us. We clean up inside and out and walk the finished windows with you before we go. You won’t be left with a pile in the driveway.

When is it time to replace windows instead of repairing them?∨

Honest answer: it depends on the window, not the house. We often find a few windows that need replacing and others that are fine. We’ll mark which is which, show you photos, and quote only what actually needs to go. That’s how we’d want to be treated.

How are replacement windows measured?∨

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.
