Skylight repairs & leak fixes in Chelmsford: what is involved?
Thinking about skylight repairs & leak fixes in Chelmsford? 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.
Flat, open landscape in much of the East means roofs take the wind, so upstand and seal details matter more than the brand of glass. Typical uses for skylight repairs & leak fixes include leaks, condensation, misted units and failed actuators.
From Chelmsford to Billericay, Witham and Maldon, the same survey-first process applies: measure, specify, fix the price, then fit.

Do you need permission in Chelmsford?
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. 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. 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.

Yes — flashings, seals, hinges and glass on pitched roof windows.
Can you repair an electric rooflight that will not open?
Often, yes — actuators, controllers and rain sensors can be replaced if parts are available.

Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
