Our Lancashire coverage takes in Rawtenstall (BB4) and nearby Accrington, Burnley and Darwen. It is about 17 miles east of Preston.

Every inspection point in Rawtenstall is photographed and logged, so you have a record to show a buyer, lender or contractor. Where a Rawtenstall wall shows cold patches or damp, the survey targets those areas first rather than sampling at random.

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.

For regulations, if cavity wall insulation follows in Rawtenstall, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

How to tell if a house already has cavity insulation

Look for a regular pattern of small patched holes in the mortar joints, often about a metre apart. Check the EPC, which may say 'filled cavity'. Ask the seller for a guarantee. The reliable answer is a borescope check, because patched holes can be from a fill that was later removed and EPCs are sometimes wrong.
