Sash window repair is well worth considering if your single hung or double hung window no longer stays open. If your window suddenly drops down like a guillotine, slides shut on its own, or falls forward when you try to open it, the problem is almost always worn or broken internal parts — not the entire window.
Mr Cranky specializes in sash window repair, restoring safety, smooth operation, and peace of mind without the high cost of window replacement.
Single & Double Hung Window Won’t Stay Open?
If your sash window won’t stay up, the issue is usually caused by one or more of the following failed components:
-
Broken spiral balances or springs
-
Worn or cracked window shoes
-
Failed locking tabs
-
Broken or brittle window locks
-
Age-related plastic fatigue from years of sun exposure
When these parts fail, there’s nothing left to support the sash — which is why the window drops shut or tips forward when opened. It’s a common issue, especially in older vinyl and aluminum windows.
No Window Replacement Needed – We Carry the Right Parts
Our sash window repair specialists carry the most common replacement parts for single and double hung windows, allowing us to complete most repairs on the first visit. In many cases, your window can be restored to like-new operation in under an hour.
Heat, UV exposure, and age cause window shoes and locking tabs to become brittle over time. Once they snap or crack, the window loses its ability to stay open or lock securely. Replacing these small components is far more cost-effective than replacing the entire window.
Stop Propping Your Window Open with Wood or Books
If you’re using a piece of wood, a book, or a stick to keep your sash window open, it’s time for a proper repair. Not only is this unsafe, but a falling window can smash glass, damage the frame, or cause injury.
All of our sash window repairs are backed by a 12-month guarantee, so you can open your windows with confidence again.
To get started, simply contact us with a brief description of the issue. If possible, attach a photo — it helps us identify the problem and ensure we bring the correct parts with us.
