How we approach skylight replacement in Cricklewood
We handle skylight replacement across Greater London, including Cricklewood. In short: replacing tired domes and failed glass with a modern rooflight. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. In Cricklewood, as anywhere, skylight replacement is the usual choice for yellowed domes, misted glass and leaking roof windows.
Jobs in Cricklewood are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
Options we can specify in Cricklewood
- Fixed to electric opening
- Dome to flat glass upgrade
- Upstand rebuild and insulation
- Like-for-like size replacement
- Misted glass unit replacement only
- Better thermal performance
- Clearer view and more light
Before you order: points to check
- Old glass and domes are disposed of responsibly
- Upstand and roof condition decide the scope
Do you need permission in Cricklewood?
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. 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. 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.
Read the planning permission guide before you commit to a design.
