How we approach skylight repairs & leak fixes in Tonbridge
Our skylight repairs & leak fixes service in Tonbridge 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.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. In Tonbridge, as anywhere, skylight repairs & leak fixes are the usual choice for leaks, condensation, misted units and failed actuators.

Planning, building control and Tonbridge
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. 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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. 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
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 charge for repair visits?
Yes, repairs are charged. We give the price before the visit.
Can you fix a misted rooflight?
A misted unit means the glass seal has failed. The sealed unit, or the whole rooflight, needs replacing.
How do I book a survey in Tonbridge?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Can you work alongside my builder in Tonbridge?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
