What are skylight repairs & leak fixes?
Across Merseyside, our skylight repairs & leak fixes work covers leak tracing, resealing, actuator repairs and glass replacement. Survey first, fixed price second, fitting third.
Rear kitchen extensions on North West semis often have small domes from decades ago that leak or have yellowed. Stone and brick terraces are typical across the North West, and roof windows in rear slopes are a common way to light attic rooms.

Planning and building rules in England
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.
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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.

How the job runs
- Tell us about the roof. Send the postcode, rough sizes and a photo or two through the form, WhatsApp or the guide-price tool.
- Free survey. For new installations a surveyor measures the opening, checks the roof build-up and talks through glass and options.
- Fixed written quote. You get the product, the work and the price in writing. Nothing is ordered or paid for until you agree.
- Fitting and handover. We fit, seal and make good, then hand over product data, warranties and any certificate paperwork.

Common questions
Do you repair roof windows too?
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.
Can you fix a misted rooflight?
A misted unit means the glass seal has failed. The sealed unit, or the whole rooflight, needs replacing.
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.
Do I need to be at home for the survey in Merseyside?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
