What do skylight repairs & leak fixes in Farnham involve?
We handle skylight repairs & leak fixes across Surrey, including Farnham. In short: leak tracing, resealing, actuator repairs and glass replacement. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. Think of skylight repairs & leak fixes for leaks, condensation, misted units and failed actuators.

Do you need permission in Farnham?
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. 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.

Common questions
Can you fix a misted rooflight?
A misted unit means the glass seal has failed. The sealed unit, or the whole rooflight, needs replacing.
Is it condensation or a leak?
Condensation forms on the inside face on cold days and comes back in the same pattern. A leak appears when it rains and often tracks down the reveal.
Can you repair an electric rooflight that will not open?
Often, yes — actuators, controllers and rain sensors can be replaced if parts are available.
