WINDOW & DOOR REPAIRS BELFAST
City Glass N.I specialises in window repairs, door repairs and glazing throughout Belfast and surrounding areas. From a single faulty hinge or misted glass unit to draught detection and full home window restoration, we focus on repairing and upgrading existing windows and doors wherever practical.
WINDOW & DOOR REPAIR SPECIALISTS IN BELFAST
With decades of experience repairing uPVC, aluminium and wooden windows and doors, City Glass N.I provides practical solutions for homes, businesses and managed properties across Belfast and surrounding areas. Our approach is simple: if your existing frames are still suitable, we look for the best way to repair and restore them rather than automatically recommending replacement.
Our specialists deal with broken glass, failed double glazing, faulty locks and mechanisms, draughts, leaks, heat loss, noise problems and difficult tilt & turn window faults. We also offer thermal imaging, full home window restoration and energy-efficient Low-E glass upgrades, helping customers get more from the windows and doors they already have.

WINDOW & DOOR REPAIR FAQs BELFAST
Find answers to some of the most common questions about our window repairs, door repairs, glazing and restoration services in Belfast.
CAN MY WINDOWS BE REPAIRED INSTEAD OF REPLACED?
In many cases, yes. If the existing frames remain suitable, problems can often be resolved by replacing worn hinges, locks, handles, gaskets, mechanisms, seals or glazing rather than replacing the complete window.
DO YOU REPLACE MISTED OR FAILED DOUBLE GLAZING?
Yes. We replace failed double glazed units affected by misting or condensation while retaining suitable existing frames. Low-E replacement glazing is also available for customers looking to upgrade their existing windows.
DO YOU OFFER EMERGENCY GLASS REPLACEMENT?
Yes. We provide broken glass and emergency glazing services. As we can make our own double glazed units, same-day emergency replacements can be available where required.
CAN YOU CHECK MY HOME FOR DRAUGHTS AND HEAT LOSS?
Yes. We use thermal imaging to help identify difficult-to-detect air leakage and heat loss around windows and doors before recommending appropriate repairs.
WHAT DOES FULL HOME WINDOW RESTORATION INCLUDE?
Depending on the condition of your windows, restoration can include replacing worn gaskets, hinges, handles, locks and mechanisms, adjusting and resealing frames and upgrading the glazing where appropriate.
WHAT TYPES OF WINDOWS AND DOORS DO YOU REPAIR?
We repair uPVC, aluminium and wooden windows, tilt & turn windows, double glazed and Velux windows, conservatory systems, uPVC and aluminium doors, patio doors and commercial shopfront doors.
