Damp investigation after cavity insulation for Billingham properties
Billingham is among the towns we cover in County Durham, alongside Stockton-on-Tees, Thornaby-on-Tees and Hartlepool. It is about 17 miles south-east of Durham.
If your Billingham installation has a guarantee, we check it first; the guarantee route may cover the work. Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Billingham properties, so you can choose who fixes them.
Wind-driven rain is the first thing the surveyor weighs up. 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.
In terms of approvals, if cavity wall insulation follows in Billingham, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
