Skylight repairs & leak fixes for Guildford: the essentials
Our skylight repairs & leak fixes service in Guildford covers leak tracing, resealing, actuator repairs and glass replacement. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Think of skylight repairs & leak fixes for leaks, condensation, misted units and failed actuators.
We work across Surrey, including Guildford, and in neighbouring towns such as Godalming and Woking. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning and building rules for Guildford
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about skylight repairs & leak fixes in Guildford
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.
Do you repair roof windows too?
Yes — flashings, seals, hinges and glass on pitched roof windows.
Can you repair an electric rooflight that will not open?
Often, yes — actuators, controllers and rain sensors can be replaced if parts are available.
Can you work alongside my builder in Guildford?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Guildford?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
