What do skylight repairs & leak fixes in Blackheath involve?
Thinking about skylight repairs & leak fixes in Blackheath? The short answer: leak tracing, resealing, actuator repairs and glass replacement. The longer answer depends on your roof, which is why we survey before we price.
Victorian and Edwardian terraces with narrow side returns are typical of much of London, and a glass roof or long flat rooflight is the usual way to keep the back rooms bright once the return is built over. Typical uses for skylight repairs & leak fixes include leaks, condensation, misted units and failed actuators.
Neighbouring towns include Greenwich (2 km) and Catford (3 km). We offer a survey date when we reply to your enquiry.

Do you need permission in Blackheath?
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.
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.

Can you repair an electric rooflight that will not open?
Often, yes — actuators, controllers and rain sensors can be replaced if parts are available.
