Damp investigation after cavity insulation in Renfrew

Damp investigation after cavity insulation in Renfrew is priced before you book, and what we find is written up with photos.

Damp investigation after cavity insulation for Renfrew properties

Renfrew is among the towns we cover in Renfrewshire and Inverclyde, alongside Paisley, Newton Mearns and Greenock. It is about 3 miles north-east of Paisley.

Damp in an insulated Renfrew home is not always the insulation's fault, so the diagnosis comes before any extraction. Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Renfrew properties, so you can choose who fixes them.

Wind-driven rain is the first thing the surveyor weighs up. Parts of Renfrewshire and Inverclyde face some of the heaviest wind-driven rain in the UK, especially exposed coastal and upland sites. Here the survey is stricter: some walls suit only certain certified systems, and some should not be filled at all.

On compliance, if cavity wall insulation follows in Renfrew, no building warrant is needed for insulation within a wall, but the work must meet the building standards.
