Window Painted Shut or Won't Open — Stuck Window Repair
The window was painted shut years ago, or it swelled in a wet summer, or the crank spins and nothing moves. Before anyone sells you new windows, most of these open again.
A window painted shut that won't open can usually be freed without replacing it. JMB Builders cuts the paint seal, frees the sash, eases swollen wood, and fixes the stops, balances, casement operators or slider tracks, across the Twin Cities. We tell you when a window is too far gone. Priced per window, quoted from photos within one business day.

Stuck windows come in a few kinds. Painted shut is the most common in older houses: the sash has been painted to the stops and the frame, and the paint acts like glue. Swollen is the next: wood sashes soak up moisture and bind in the frame. Racked is when the frame has shifted out of square, and the sash wedges. Casements get stuck when the operator strips or the hinges bind, and basement sliders when the track fills with dirt and corrosion.
Freeing a painted-shut sash is a patient job. The paint line is cut all the way around with a window zipper or a knife, inside and out, and the sash worked loose without prying against the glass. Then the stops come off if they are painted in tight, the edges are scraped and eased where they bind, and the channels waxed so it slides. Broken sash cords or worn balances are replaced while it is apart.
Some windows are past it: sashes rotted through, glass failed, a frame that has moved too far. Those are replacement windows, and we tell you which ones. A basement window you need to get out of in a fire should open; that one gets done first.

Window Painted Shut or Won't Open — Stuck Window Repair: questions, answered
How do you open a window that is painted shut?
The paint line is cut all the way around the sash, inside and out, with a window zipper or a sharp knife. Then the sash is worked free with light taps, never pried against the glass. If the stops are painted in tight, they come off and go back on.
Should I replace a window that won't open?
Not first. Most stuck windows are painted shut, swollen or have a broken balance or operator, and those are repairs. Replace it when the sash is rotted through, the glass has failed, or the frame has moved too far to fix.
Why won't my wood window open in the summer?
The wood swells with humidity and binds in the frame, especially where the paint is thick. Easing the binding edges and waxing the channels fixes it. Sealing bare wood keeps it from happening again.
Can you fix a casement window that won't open?
Usually. A crank that spins is a stripped operator, and a sash that will not move may have seized hinges or be painted shut. Operators and hinges are replaced with parts for your window.
Why won't my basement slider window slide?
The track is full of dirt, the rollers are worn, or the frame has corrosion. Cleaning the track and replacing the rollers where the maker sells them fixes most. A basement window you might need to escape through should open easily.
Do you fix windows with broken sash cords?
Yes. The sash comes out, the weight pocket is opened, and new cord or chain goes on the weights. Or the old system is replaced with spiral balances. The window then stays up where you put it.
