How it works
Inspect the window
We test the operation, check for drafts and identify any broken hardware or damaged seals.
Repair hardware and seals
We fix or replace latches, balances and weatherstripping so the window closes and seals completely.
Verify the fix
We open and close the window several times, check for air infiltration and make sure it latches firmly.

Window Repair & Weatherstripping — FAQ
What type of weatherstripping works best?
It depends on the window type. V-strip works well on double-hung windows; foam tape suits casements. We choose the right material for each gap.
Can you fix a window that won't stay up?
Yes. Double-hung windows rely on spring or spiral balances. We replace the faulty balance so the sash holds at any height without a prop.
Is it worth repairing an old window instead of replacing it?
For a working sash with minor hardware or seal issues, repair is usually a fraction of replacement cost. We'll give you an honest assessment.
How long does weatherstripping last?
Foam tape lasts a few years; V-strip and door sweeps typically last five to ten years. High-traffic windows wear faster.
