New basement windows from iFixBasements are double-pane vinyl replacement windows, hopper or slider, that replace the old single-pane units builders put in your foundation wall. They seal tighter, let daylight in, and still open and close.
I personally inspect and design the fix; a licensed & insured certified dealer crew installs it. The estimate is free, and no-money-down financing is available.
This is part of my energy savings work, and it can go in at any phase of my three-phase approach to basement finishing. See all three phases.
Put your hand near an old basement window on a cold January morning and you’ll feel it right away. Builders tend to put the simplest window in the basement: single pane, with a frame that has warped, rusted, or rotted and sashes that don’t seal. They’re some of the leakiest openings in the whole house, and they’re easy to overlook because nobody looks at them.
Signs your basement windows need replacing
- A cold draft at the window, even when it’s shut
- Rusted, rotted, or warped frames and sashes that don’t close tight
- Frost, condensation, or dampness on the glass or frame
- Cracked or fogged glass
- Dirt, leaves, or insects coming in around the edges
- Windows that are stuck shut or hard to open
If a couple of these sound familiar, those windows are probably worth a look.
Why basement windows leak more than you’d expect
In heating season, warm air rises through a house and escapes near the top, which pulls cold air in to replace it at the bottom. The easiest way in is the gaps around basement windows. That cold air makes the basement colder, makes the heating system work harder, and chills the floors above it. A leaky window can also feed dampness: in summer it lets warm, humid air onto cooler surfaces, where it condenses. That’s the same dampness behind wet basements and crawl spaces.
What goes in
- Double-pane glass. Two panes with a sealed space between them, instead of one thin sheet.
- Vinyl frames. They won’t rust or rot the way old metal and wood frames do.
- Hopper or slider. A hopper hinges at the bottom and opens inward; a slider slides sideways. I match the style to the opening.
- Sized to your opening. I measure each window so the new unit fits and is sealed to the wall all the way around.
- Windows that open. They ventilate and, where needed, stay a way out.
Where it should be handled with care
I want to be straight with you about this one. A window that someone might need to escape through, like the window in a basement bedroom, has to stay operable and clear. I won’t fix one shut, and I won’t shrink an opening that someone could need to climb through. At the estimate I’ll tell you which of your windows are in that group. For windows you don’t need to open, a basement storm window is a different option, and I’ll tell you honestly which suits each opening.
How I handle it
- I look at every window. Size, condition, the wall around it, and whether anyone could ever need to climb out of it.
- I explain what I’d do and why. Which windows get replaced, which stay, and what each opening needs.
- I ask what you want fixed. Then we price every line together, and you can take out anything you’d rather do yourself.
- A dealer crew installs it. I personally inspect and design the fix, then a licensed & insured certified dealer crew installs it.

Why homeowners call me
I’ve been doing this long enough to have over 100 five-star Google reviews from people in exactly this situation, and I share a lot of real basement footage — the good, the bad, and the genuinely gross — with about 10,000 followers on Instagram (@ifixbasements) so you can see what these spaces actually look like, not just stock photos.
Where I work
I estimate jobs throughout New York — all five NYC boroughs, Long Island (Nassau and Suffolk), Westchester, Putnam, Rockland, Orange, Ulster, Dutchess, Sullivan, Greene, and Columbia Counties — plus northern and central New Jersey (down through Mercer and Monmouth Counties) and Wayne and Pike Counties in Pennsylvania.

Straight Answers
Frequently asked questions
What kind of windows go in?
Double-pane vinyl replacement basement windows, as a hopper (hinged at the bottom and opening inward) or a slider (sliding sideways). I’ll tell you which suits each opening at the estimate.
Will the new windows open?
Yes. Unlike a fixed storm panel, a replacement window opens and closes, so you can still ventilate and get out.
Can I replace a window that someone might need to escape through?
Yes, and it has to stay operable. A basement window that someone might need to climb out of, such as one in a basement bedroom, must open and stay clear. I won’t fix one shut or shrink the opening, and I’ll tell you at the estimate which windows fall into that group.
Should I get new windows or storm windows?
Storm windows are a clear interior panel over the old window, and they’re fixed, so they only suit windows you don’t need to open. Replacement windows suit windows that are worn out or that you want to keep operable. I’ll tell you which fits each opening.
What drives the cost of new basement windows?
The number of windows, their sizes, the style, and the condition of the opening around each one. I don’t quote a number until I’ve seen it in person; the estimate is free, and no-money-down financing is available.
Who installs it?
I personally inspect and design the fix, then a licensed & insured certified dealer crew installs it.
