How we approach skylight replacement in Kendal
Skylight replacement in Kendal means replacing tired domes and failed glass with a modern rooflight. We cover the LA9 district and the rest of Cumbria, with a survey before any price is fixed.
Exposed hillside towns in the North West need flashing and seal details that cope with wind-driven rain. In Kendal, as anywhere, skylight replacement is the usual choice for yellowed domes, misted glass and leaking roof windows.
Kendal is around 64 km from Carlisle, and we survey and fit throughout that part of Cumbria, including the LA9 district.

Planning, building control and Kendal
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.
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.

More we do in Kendal
Skylight replacement in Kendal: questions
Can I go bigger when replacing?
Possibly. Enlarging the opening means trimming joists, so we check the structure first.
Can you replace only the misted glass?
Sometimes, if the frame is sound and the maker supplies replacement units. Often a complete new rooflight costs little more and performs better.
What do you do with the old unit?
We remove it from site and recycle what can be recycled.
Can you work alongside my builder in Kendal?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
How do I book a survey in Kendal?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
