Built for Harrow homes

Around Harrow and the wider county, housing stock runs to Victorian terraces, side-return kitchen extensions and flat-roof rear additions where a roof lantern is the default way to pull daylight deep into the plan. We've specified and supplied for exactly these property types across Greater London, so recommendations come from real local precedent.

Every lantern is thermally broken aluminium as standard, glazed with 28mm argon-filled units, and available with self-clean and solar-control coatings. Supply-only orders include kerb specifications and fitting documentation; installed projects carry our written workmanship guarantee on top of the 10-year product cover.

Harrow, Ealing, Enfield and Kingston upon Thames and the rest of Greater London all sit inside standard coverage: free surveys, free quotes, and a response within 1 working hour.

Roof Lantern Repairs in Harrow — common questions

Water is dripping from my lantern — what's the likely cause?

Could be five things: ridge capping, hip junction, perimeter seal, kerb flashing or the flat roof itself, with condensation a sixth impostor. We trace the actual path before quoting, so you pay to fix the real fault.

Can you repair lanterns you didn't supply?

Yes — repairs cover all major aluminium, uPVC and timber systems regardless of who installed them. Photos of the lantern and the fault speed up the first visit.

Is condensation between the panes repairable?

The pane itself isn't — once a sealed unit's edge seal fails it's replaced, not resealed. The frame stays; only the glass unit changes.

When is repair not worth it?

When the frame itself has failed: non-thermally-broken early aluminium running with condensation, or softwood gone soft. We'll tell you straight on survey and price both routes.

Can I book installation in Harrow?

We do. Harrow and the surrounding Greater London towns are core territory for both our installation teams and our supply-only delivery routes.
