How much should I budget for external wall insulation in Weymouth?
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 Weymouth and fixes the total in writing.
Do you cover Dorchester as well as Weymouth?
Yes. From Weymouth we also cover Dorchester, Poole and Yeovil, and the rest of Dorset.

It depends on the walls. Most brick houses in Weymouth 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.
