Why Choose Replacement Over Repair?
At Restoration Glazing, we always try repair first — it's usually cheaper and less disruptive. But sometimes replacement is the smarter long-term investment:
- • Windows or doors over 20 years old — older frames lose thermal efficiency and structural integrity
- • Severely damaged or warped frames — repair costs can approach replacement costs
- • Energy efficiency upgrades — modern A-rated windows can cut heat loss by up to 80%
- • Security upgrades — new windows and doors meet current PAS 24 security standards
- • Aesthetic refresh — new windows and doors transform the look of your home

Frequently Asked Questions
UPVC window replacement typically costs £350–£800 per window depending on size and specification. Full house projects (8–10 windows) usually range from £3,000–£7,000. Composite front doors start from around £900. We provide free, detailed quotes with no obligation.
In most cases, no. Like-for-like window and door replacements in non-listed buildings fall under permitted development. As FENSA registered installers, we handle all building regulation compliance and certification on your behalf.
A typical 3-bedroom house with 8–10 windows takes 2–3 days. Single window or door replacements are usually completed in half a day. We always aim to minimise disruption.
If individual components have failed (handles, locks, hinges, seals, glass units) but the frames are sound, repair is usually the better option. If frames are warped, cracked, or over 20 years old, replacement offers better value long-term. We offer both and give honest advice.
