Damp investigation after cavity insulation for Burnley properties
If your property is in Burnley or the BB10 district or nearby Nelson, Colne and Accrington, it is within our Lancashire coverage. It is about 19 miles east of Preston.
Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Burnley properties, so you can choose who fixes them. Damp in an insulated Burnley home is not always the insulation's fault, so the diagnosis comes before any extraction.
Local weather affects which walls can be filled. Parts of Lancashire 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 Burnley, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Rules in England

Common causes we check
Defective pointing, cracked render and porous bricks letting rain in; leaking gutters and downpipes; fill bridging the cavity where mortar droppings or debris have collected; ground levels above the damp-proof course; and condensation from cooking, drying clothes and too little ventilation.
