What do skylight repairs & leak fixes in Northolt involve?
We handle skylight repairs & leak fixes across Greater London, including Northolt. In short: leak tracing, resealing, actuator repairs and glass replacement. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
London homes often run deep from front to back, so the middle of the ground floor is the darkest space — exactly where an overhead rooflight earns its keep. Skylight repairs & leak fixes suit leaks, condensation, misted units and failed actuators.
Northolt is around 17 km from central London, and we survey and fit throughout that part of Greater London, including the UB5 district.

Do you need permission in Northolt?
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.
Read the planning permission guide before you commit to a design.

Common questions
Do you charge for repair visits?
Yes, repairs are charged. We give the price before the visit.
Why is my skylight leaking?
Common causes are a failed seal, a membrane that has split or lifted at the upstand, a low upstand, blocked drainage or condensation mistaken for a leak.
Can you fix a misted rooflight?
A misted unit means the glass seal has failed. The sealed unit, or the whole rooflight, needs replacing.
