New Windows & Installation in Leonia, 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.

Usually it’s worn balances, swollen wood, old paint sealing the sash, or a frame that has shifted over time. Sometimes a window can be freed up, but on older windows the problem tends to come back. If the window also drafts or the sill is soft, replacement is usually the better fix. We’ll take a look for free.

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.

We do. Financing for qualified homeowners is available through our financing partner, which helps when a whole-house window project doesn’t fit neatly into one check. Visit our financing page or ask us about it when we come out to measure your windows.

Not always. If only a few windows are failing, replacing those makes sense. Doing the whole house at once keeps styles and glass matching and means one project instead of several. We’ll give you an honest look at every window and price it both ways if you want, so you can decide what fits your budget.

Each window gets the same treatment. Old unit out. Opening inspected for rot, and you see it first. Sill pan and flashing in. New window set, then insulated with low-expansion foam and sealed on both sides. Exterior trim capped to match. When we’re done, we clean up, and you open and lock every window with us during the final walkthrough.

Look for fog between the panes, condensation that won’t wipe off, soft or rotted sills, drafts around the frame, and sashes that stick, slam or won’t lock. Those are signs a window is failing. If only a couple show them, replace those. If most do, a whole-house replacement is often smarter. We’ll give you a straight answer, with photos.
