How much should I budget for external wall insulation in Slough?
Budget around £109–£175 per square metre of wall for the system and finish, plus scaffolding priced per house. The survey measures your walls in Slough and fixes the total in writing.
Do you cover Windsor as well as Slough?
Yes. From Slough we also cover Windsor, Maidenhead and Gerrards Cross, and the rest of Berkshire.

It depends on the walls. Most brick houses in Slough suit EPS with silicone render; older stone or lime-built walls suit wood fibre or insulating lime render; and blocks need mineral wool. The free survey recommends one and explains why.
