Repairs & servicing for N21 homes
For period properties, repairing rather than replacing existing windows can avoid planning complications, particularly where original features are expected to be retained.
On Victorian homes with older uPVC sashes or casements, replacing worn hinges and seals can often cure draughts without disturbing the frames or decoration. Bay windows on 1930s houses often suffer from misted units and dropped sashes, which can usually be fixed with replacement glass and hinge adjustment.
These are houses where originality matters: mock-Tudor details, stained glass toplights and wide bays. We take care to match them rather than fit standard flat frames. The Hertford Loop line runs through, though most roads are quiet. N21 is about 3.1 miles from our factory.
We repair windows and doors of most types, including replacing misted glass units, faulty locks, handles, hinges and worn seals. Repairs suit homeowners, landlords and businesses whose frames are basically sound but not working properly, and can be a sensible alternative to full replacement.
- Replaces misted or broken glass units
- Fixes sticking, dropped or draughty doors
- Extends the life of sound frames
Questions from N21
Do I need planning permission for repairs & servicing in N21?
Repairs such as replacing glass units, locks, hinges and seals do not need planning permission or Building Regulations notification, though replacing a whole window or door frame falls under FENSA rules.
How soon can you fit repairs & servicing in N21?
Lead times vary by product and workload — confirmed with your quote. Being about 3.1 miles from our factory makes surveys, fitting days and aftercare visits easy to arrange.
Do you repair windows and doors you did not install?
We can repair most uPVC, aluminium and composite windows and doors, whatever their age or original installer. Parts for very old or discontinued systems can sometimes be hard to source, so we'll tell you honestly if replacement makes more sense for your N21 property.
Can I see samples before I decide?
Yes. Our showroom is at Unit G, 1 Anthony Way, London N18 3QT (Mon–Fri 8am–5pm), about 3.1 miles from N21. We can also bring samples to your home in N21 at the free survey.
