What does skylight installation in Egham involve?
Skylight installation in Egham means survey, supply and fit — new openings, extensions and fit-only work. We cover the TW20 district and the rest of Surrey, with a survey before any price is fixed.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. In Egham, as anywhere, skylight installation is the usual choice for builders' projects and retrofits into finished roofs.
We work across Surrey, including Egham, and in neighbouring towns such as Staines and Ashford, Surrey. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning and building rules for Egham
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. 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.

Questions about skylight installation in Egham
How long does installation take?
Fitting into a prepared upstand takes about a day. A new opening in an existing roof, including making good, often takes two to three days.
Who handles building control?
We tell you which route applies — building control approval, a building warrant in Scotland, or in England and Wales self-certification by a registered competent person — and supply the product data.
Do you fit rooflights bought elsewhere?
Yes. We check the product and the opening first, and our workmanship terms cover the fitting rather than the product.
Can you work alongside my builder in Egham?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Egham?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
