Repairs & maintenance
Window & door repairs, sorted quickly
Misted glass, broken locks, dropped doors and draughts — fixed fast and fairly across South Wales. We repair windows and doors of any age, whoever fitted them.

What we fix
Common repairs we carry out
If it lets in draughts, won't lock or has gone foggy, there's a good chance we can put it right.
Misted & failed glass
Foggy or condensation-filled double glazing? We replace the sealed unit only — no need for a whole new window.
Locks & multipoint mechanisms
Sticking, snapped or insecure locks repaired or replaced, including anti-snap upgrades for UPVC doors.
Handles & cylinders
Worn or broken window and door handles, euro cylinders and letterplates swapped quickly.
Hinges & alignment
Dropped doors realigned and tired hinges replaced so everything opens and closes smoothly again.
Draughts & seals
Perished gaskets and worn weather-seals renewed to stop draughts and keep the heat in.
Broken glass replacement
Cracked or smashed panes measured and replaced — toughened and obscure glass available.
