How we approach skylight repairs & leak fixes in Chorley
We handle skylight repairs & leak fixes across Lancashire, including Chorley. In short: leak tracing, resealing, actuator repairs and glass replacement. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Converted mills and warehouses in the North West often have large rooflights or glass roofs that need specialist replacement. Typical uses for skylight repairs & leak fixes include rooflights that have stopped opening or started dripping.
We work across Lancashire, including Chorley, and in neighbouring towns such as Leyland and Darwen. Access, parking and how the glass reaches the roof are all checked at the survey.

Do you need permission in Chorley?
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.
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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
See our building regulations guide for U-values, glazing limits and self-certification.

Skylight repairs & leak fixes in Chorley: questions
Do you charge for repair visits?
Yes, repairs are charged. We give the price before the visit.
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.
How do I book a survey in Chorley?
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 Chorley?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
