Why Doesn’t the Window Fall Every Time You Open It?
A movable window sash has weight.
In hung windows, a hidden mechanism helps counterbalance that weight.
That component is commonly called the:
Sash balance.
What Happens When It Fails?
Common symptoms include:
- Window falls shut
- Sash won’t stay open
- One side feels heavier
- Window becomes difficult to lift
- Sash sits crooked
Does This Mean the Entire Window Needs Replacement?
Not always.
If the rest of the window is:
- Structurally sound
- Weather-tight
- In good condition
hardware repair may be possible.
When Does Replacement Make More Sense?
Look at the complete unit.
Replacement becomes more relevant when balance problems are combined with:
- Frame deterioration
- Failed glass
- Air leakage
- Water damage
A Window That Won’t Stay Open May Have a Hardware Problem, Not a Glass Problem.
Envirotech Exteriors can assess the overall window condition before recommending whether a failing unit should be repaired or replaced.
