Some of what's wrong with your windows is a balance, a seal, or a piece of hardware. Some of it is a failed unit that no amount of caulk will save. We walk the house, tell you which is which, and put it in writing — including the windows we think you should leave alone this year.

What's Actually Wrong With Your Window
Almost every window complaint traces back to one of four failures. Two are repairs, one is usually a replacement, and one depends entirely on what's behind the trim. Here's how to tell them apart — and what we'd do about each.
Fogged Or Filmy Glass
Haze between the panes means the seal failed and the insulating gas is gone. It can't be resealed, and the glass won't clear up. On a newer window we can often replace just the sash or glass unit; on an older one, the rest of the window is usually the same age as the seal.
Sash Won't Stay Up → Repair
A window that slams shut or won't hold position has a broken balance or spring — a part, not a window. Same for a crank that spins, a lock that won't line up, or a sash that's simply painted shut. These are service calls, and we quote them as service calls.
Drafts And Leaks → Depends
Air moving past the sash is often weatherstripping and hardware adjustment. Air and water coming in around the frame is a different problem — that's the seal between the window and the house, and it usually means replacement with proper flashing. We check both before saying which.
Rot, Soft Frames, Water Stains → Replace, And Look Deeper
Soft wood at the sill, peeling interior paint, or staining under the window means water has been getting in for a while. The window has to come out, and we check the framing behind it while it's open. This is the one that gets worse and more expensive every season you wait.
Frequently Asked Questions
The fog itself, no. Haze between the panes means the seal around the insulated glass failed and the argon has escaped — there's no way to reseal it in place, and "defogging" services only clear the appearance for a while without restoring the insulation you lost. What can sometimes be done is replacing just the glass unit or the sash while keeping the existing frame, which is a real option on a newer window in a sound frame. On a twenty-year-old window, the seal failing is usually the first of several parts to go, and most homeowners get more out of replacing the unit.
Per window, repair is almost always cheaper — a balance, a crank, or new weatherstripping is a fraction of a replacement. The math changes when you're repeating it. If we've been out twice for the same window, or if half the windows on one elevation are showing the same failure at the same age, you're funding a replacement in installments and getting none of the energy savings. Our rule: we repair what's genuinely a parts problem and tell you plainly when you're maintaining something that's finished.
Yes, within reason. Hardware, balances, weatherstripping, and glass units on common brands are usually straightforward. Where it gets hard is discontinued lines and proprietary parts — some manufacturers stopped making the hardware their own windows need. If yours is one of those, we'll tell you that rather than order a part that never arrives.
Not usually. Most replacements are insert installations: the old sashes come out, the existing frame stays, and the new unit fits inside it — your interior trim and exterior siding are left alone. Full-frame replacement, where everything comes out down to the rough opening, is what we recommend when there's rot in the frame or sill, or when the original install was never flashed properly. It's more work, and we only call for it when there's a reason you'd agree with once you saw it.
Free in-home estimates are typically scheduled within a few days. If you've got an actively leaking window or broken glass, say so when you call — that gets handled differently than a quote for a project you're planning.
