How we approach skylight replacement in Nailsea
Thinking about skylight replacement in Nailsea? The short answer: replacing tired domes and failed glass with a modern rooflight. The longer answer depends on your roof, which is why we survey before we price.
Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs. Think of skylight replacement for yellowed domes, misted glass and leaking roof windows.
Nailsea is around 28 km from Bath, and we survey and fit throughout that part of Somerset, including the BS48 district.

Consents for skylight replacement in Nailsea
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.
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. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.

Questions about skylight replacement in Nailsea
Will it mess up my ceiling?
We protect the room and make good the reveal. Minor decoration may be needed afterwards.
What do you do with the old unit?
We remove it from site and recycle what can be recycled.
Can I go bigger when replacing?
Possibly. Enlarging the opening means trimming joists, so we check the structure first.
How do I book a survey in Nailsea?
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 Nailsea?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
