How we approach skylight replacement in Chester-le-Street
Our skylight replacement service in Chester-le-Street covers replacing tired domes and failed glass with a modern rooflight. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Many North East homes have loft rooms that benefit from larger roof windows with blackout blinds. In Chester-le-Street, as anywhere, skylight replacement is the usual choice for yellowed domes, misted glass and leaking roof windows.
We work across Durham, including Chester-le-Street, and in neighbouring towns such as Washington and Houghton-le-Spring. Access, parking and how the glass reaches the roof are all checked at the survey.

Do you need permission in Chester-le-Street?
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. 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.

Questions about skylight replacement in Chester-le-Street
Will it mess up my ceiling?
We protect the room and make good the reveal. Minor decoration may be needed afterwards.
Can I go bigger when replacing?
Possibly. Enlarging the opening means trimming joists, so we check the structure first.
How long does a replacement take?
Usually a day for a standard rooflight on a sound upstand.
Can you work alongside my builder in Chester-le-Street?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
How do I book a survey in Chester-le-Street?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
