Skylight repairs & leak fixes in Streatham: what is involved?
Skylight repairs & leak fixes in Streatham means leak tracing, resealing, actuator repairs and glass replacement. We cover the SW16 district and the rest of Greater London, with a survey before any price is fixed.
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. Think of skylight repairs & leak fixes for rooflights that have stopped opening or started dripping.
Streatham sits about 2 km from Balham and 4 km from Clapham, and we cover the whole SW16 postcode district and the roads in between.

Planning, building control and Streatham
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. 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.

Questions about skylight repairs & leak fixes in Streatham
Why is my skylight leaking?
Common causes are a failed seal, a membrane that has split or lifted at the upstand, a low upstand, blocked drainage or condensation mistaken for a leak.
Can you fix a misted rooflight?
A misted unit means the glass seal has failed. The sealed unit, or the whole rooflight, needs replacing.
Do you charge for repair visits?
Yes, repairs are charged. We give the price before the visit.
