Cavity wall insulation for landlords for Darlington properties

Our County Durham coverage takes in Darlington (DL1) and nearby Newton Aycliffe, Stockton-on-Tees and Thornaby-on-Tees. It is around 17 miles south of Durham.

Blocks of flats in Darlington are surveyed as a whole, because the cavity runs across every flat in the building. For commercial buildings in Darlington, the survey also considers building use and fire requirements before a material is specified.

Exposure matters for every cavity wall. County Durham has a mix of moderate and more exposed sites. Hilltop, coastal and west-facing walls take the brunt of wind-driven rain, so the survey records exposure for each elevation before a material is chosen.

For regulations, in Darlington filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
