Suggested Solution

Cost Impact

Drafty Windows/ Worn Seals

Re-sealing or replacing the rubber gaskets.

Low

Sticking/ Misaligned Windows

Changing hinges, locks, and mechanisms.

Low

Broken Handles and Locks

Changing the specific hardware elements.

Low

Rotted Wooden Frames

Lumber repair or partial frame replacement.

Moderate to High

Shattered Frame (Upvc/Aluminum)
