Wall tie replacement for Blackburn properties
If your property is in Blackburn or the BB2 district or nearby Darwen, Accrington and Chorley, it is within our Lancashire coverage. It is around 9 miles east of Preston.
If your Blackburn 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 Blackburn properties, so you can choose who fixes them.
Exposure matters for every cavity wall. 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 the rules side, if cavity wall insulation follows in Blackburn, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Signs of wall tie failure
Horizontal cracks in mortar joints at regular vertical intervals, bulging brickwork, or lifting of the roof verge. Older galvanised ties, especially in walls built before the 1980s, are the usual suspects.
