Great communication. Paul was very thorough and dealt with our sticking patio doors. Although he came a little later than arranged we were kept fully informed and were able to track his journey. Very friendly. Pleased with the price of the work.

Third time using this company and as always, brilliant job. This time for replacement sealed units. Always my first call for glazing work.
When repair isn't worth it, replacement is. Across Southampton, the trigger is usually one of three things: the frame itself has gone (rotted, warped, or simply worn out after 25+ years), the energy efficiency is too poor to be worth keeping (single glazed, or first-generation double glazed with broken seals), or the homeowner is upgrading the look — moving from older brown UPVC or 1990s plastic to a modern flush sash, anthracite finish, or A+ rated unit.
Restoration Glazing is FENSA-registered, which means every full window installation we carry out across Southampton is certified to UK Building Regulations and you receive a FENSA certificate (which you'll need to show when you sell your property). We supply and fit the full range — casement, tilt-and-turn, flush sash, sliding sash replicas for heritage homes, bay and bow, French casements — across every Southampton postcode (SO14 to SO19).
Most UPVC window replacements in Southampton cost between £350 and £800 per window depending on size, glass spec, frame finish and access. A whole-house replacement (typical 3-bed semi, 8 windows) is usually £3,000-£6,000. We provide a free survey and written fixed-price quote; we never use high-pressure sales or "today only" pricing.
