Skylight repairs & leak fixes in Windsor: what is involved?
For Windsor 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.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Think of skylight repairs & leak fixes for rooflights that have stopped opening or started dripping.
We work across Berkshire, including Windsor, and in neighbouring towns such as Slough and Egham. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Glass unit replacement
- Upstand and membrane repairs
- Actuator, motor and control repairs
- Condensation diagnosis
- Planned maintenance visits
- Honest repair-or-replace advice
- Seal and flashing repairs
What to check first
- Commercial roofs need access and fall protection
- Parts availability varies with the age of the unit
Planning, building control and Windsor
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. 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.
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.
Read the planning permission guide before you commit to a design.
