Windows That Won’t Stay Up, Stick or Won’t Latch:
Balance Springs and Sash Hardware
A window that slams shut when you let go has a broken balance. It’s one of the most common window findings, and usually one of the simpler fixes.
At 81 houses, Russ found windows that didn’t work as intended. Failed balance springs were the biggest single title, with more than 20 findings across a few wordings, followed by windows that wouldn’t latch, were stuck, or were hard to slide or open.
These rarely make a report summary. They’re still the thing a new owner notices the first warm evening they try to open a window.
Balance springs
Single-hung and double-hung windows have a sash that slides up and down. A balance in each side track holds it wherever you let go. Older wood windows used ropes and weights. Most vinyl and aluminum windows use a coil spring, a spiral rod in a tube, or a block-and-tackle spring.
When a balance breaks, the sash drops or creeps closed. A Vancouver report described many single-hung windows with balances not working as intended: the window won’t stay open on its own, which makes it hard to use and can be a safety hazard. The recommendation was a qualified window repair professional to service or replace them. Balances are replaceable parts on most windows.
Windows that won’t latch
A sash lock only works if its two halves meet. In a Vancouver house, the primary bedroom window didn’t latch in the locked position. In Salem, a bedroom window had its latch hardware missing. Causes range from a bent or broken latch to a sash that has dropped slightly or a frame that has racked.
Sometimes it’s as simple as the sash not being pushed all the way down. Russ notes it when the latch won’t engage with the window closed.
Sticking and hard to open
In a Portland house, several double-hung windows had one or both sashes that couldn’t be opened during the inspection. Old paint, dirt in the tracks, swelling wood and failed balances all play a part. Sliding windows get gritty tracks and worn rollers. Casements get stripped cranks. The Pella casement post covers one brand’s specific problems.
On old wood windows, a sash painted shut is common. The single-pane wood window post covers that type.
Bedrooms and emergency exits
A bedroom window may be the second way out in a fire. If it’s stuck, painted shut, missing its crank or too small, it can’t serve that role. Russ checks bedroom windows for operation and notes when one appears too small or too high for emergency escape. The egress window post covers the size and height rules.

What Russ checks
He operates a representative number of accessible windows, checking that they open, stay open, close and latch, and looks for failed seals, damage and signs of water at the sills. He doesn’t repair or adjust hardware. Operating problems get a recommendation for a qualified window repair contractor.
- Open each window partway and let go: does it hold?
- Close it fully and try the lock
- Listen for grinding in sliding tracks
- Make sure each bedroom has at least one window that opens fully
- Look for paint sealing a sash to its frame
Windows that wouldn’t stay up, stuck, or wouldn’t latch came up at 81 of Russ’s inspections. Failed balance springs were the most common cause, and they’re replaceable parts on most windows. Bedroom windows that don’t open get the closest look.
