Skylight replacement for Slough: the essentials
Our skylight replacement service in Slough 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.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. In Slough, as anywhere, skylight replacement is the usual choice for yellowed domes, misted glass and leaking roof windows.
Neighbouring towns include Windsor (3 km) and Maidenhead (9 km). We offer a survey date when we reply to your enquiry.

Planning and building rules for Slough
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.
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. 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.

Questions about skylight replacement in Slough
Will it mess up my ceiling?
We protect the room and make good the reveal. Minor decoration may be needed afterwards.
Can you replace only the misted glass?
Sometimes, if the frame is sound and the maker supplies replacement units. Often a complete new rooflight costs little more and performs better.
How long does a replacement take?
Usually a day for a standard rooflight on a sound upstand.
Can you work alongside my builder in Slough?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
