Skylight repairs & leak fixes for Feltham: the essentials
Our skylight repairs & leak fixes service in Feltham covers leak tracing, resealing, actuator repairs and glass replacement. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. Skylight repairs & leak fixes suit leaks, condensation, misted units and failed actuators.
We work across Greater London, including Feltham, and in neighbouring towns such as Ashford, Surrey and Hounslow. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning and building rules for Feltham
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.
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.
Our planning guide covers each nation in more detail.
