Damp investigation after cavity insulation for Skelmersdale properties

Our Lancashire coverage takes in Skelmersdale (WN8) and nearby Ormskirk, Chorley and Leyland. It is about 15 miles south of Preston.

If your Skelmersdale installation has a guarantee, we check it first; the guarantee route may cover the work. Where a Skelmersdale wall does need work, bricks are lifted and rebuilt in matching mortar, and the cavity is checked with a camera before it is closed up.

Wind-driven rain is the first thing the surveyor weighs up. 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.

As for paperwork, if cavity wall insulation follows in Skelmersdale, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Rules in England
