What affects the price?
- Glass size & thickness — larger panes and thicker units cost more.
- Glass specification — A-rated, Low-E, toughened, laminated or obscure glass each carry different costs.
- Access — upper floor or awkward access can add a small surcharge.
- Hardware brand — branded locks and hinges (Yale, ERA, Mila) cost more than generics but last longer.
- Volume — multiple units quoted together attract a discount per unit.
Repair or replace?
Repair is best when…
- • Sealed units are misted but frames are sound
- • A single pane is cracked
- • Handles, hinges or locks have failed
- • Windows are under 20 years old
Replacement makes sense when…
- • Frames are warped, cracked or rotten
- • Multiple units have failed across the property
- • You want A-rated energy efficient glass
- • Security upgrades are needed
