How we approach skylight repairs & leak fixes in Greenwich
For Greenwich homes and buildings we offer skylight repairs & leak fixes: leak tracing, resealing, actuator repairs and glass replacement. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
London homes often run deep from front to back, so the middle of the ground floor is the darkest space — exactly where an overhead rooflight earns its keep. Skylight repairs & leak fixes suit rooflights that have stopped opening or started dripping.
Jobs in Greenwich 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.

Planning and building rules for Greenwich
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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.
