How we approach skylight repairs & leak fixes in St Helens
For St Helens 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.
Stone and brick terraces are typical across the North West, and roof windows in rear slopes are a common way to light attic rooms. Skylight repairs & leak fixes suit leaks, condensation, misted units and failed actuators.

Planning and building rules for St Helens
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. 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.
