Windsor: walls, weather and approvals
As well as Windsor itself, we quote in Slough, Egham and Staines. It's roughly 16 miles from Windsor to Reading, the largest town in Berkshire. Homes across the South East range from inter-war semis and post-war estates, which are mostly cavity-walled, to older solid-walled cottages and Victorian town terraces.
Much of Berkshire sits in the lower wind-driven rain exposure bands, which keeps the choice of finishes wide — though hilltop, coastal and exposed gable walls can still need a tougher specification, so we check the actual site.
On mixed-tenure blocks in Windsor, we agree access and resident notices with the managing agent before scaffold goes up.

Permissions in England
Before quoting in Windsor, we check whether the property is in a conservation area, under an Article 4 direction or listed, because that decides whether changing the outside needs planning permission.
If the work covers more than half of a wall, or a quarter of the building's whole envelope, it counts as renovating a thermal element, with a target of about 0.30 W/m²K where feasible.
On residential buildings with a storey 11 metres or more above ground, guidance points to non-combustible external wall materials, and combustible materials are banned in relevant buildings 18 metres and over, so we specify mineral wool systems there.
How disruptive is it for residents?
Most work happens from scaffolding outside. Residents may need to allow brief access to extend window cills, vents or flues from the inside. We provide a notice for residents covering dates, scaffold, and how to raise concerns.

Flats and blocks in Windsor: questions
Do you work on high-rise buildings?
Tell us the height and number of storeys. Buildings in the higher-risk category have a separate regulatory route, and we'll say plainly if we're not the right contractor.
Do flats need planning permission for EWI?
Yes. Permitted development rights for external alterations apply to houses, not flats or maisonettes, so an application is needed.
Who pays for EWI on a leasehold block?
In England and Wales, usually the leaseholders through the service charge, depending on the lease, and the landlord must follow the Section 20 consultation process for major works.
Do you cover Windsor?
Yes — we survey and quote EWI for flats and blocks in Windsor (SL4) and nearby Slough, Egham and Staines, with a fixed written price before any work starts.
