Damp investigation after cavity insulation in Westhoughton

Westhoughton homeowners, buyers, landlords and agents can book a damp investigation with the price agreed first. A damp investigation finds out why an insulated wall is showing damp or mould: rain getting in through defects, bridged or wet fill, debris in the cavity, a breached damp-proof course, or condensation.

Damp investigation after cavity insulation for Westhoughton properties

If your property is in Westhoughton or the BL5 district or nearby Atherton, Tyldesley and Leigh, it is within our Greater Manchester coverage. It is roughly 12 miles west of Manchester.

Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Westhoughton properties, so you can choose who fixes them. Where a Westhoughton 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. Greater Manchester has a mix of moderate and more exposed sites. Hilltop, coastal and west-facing walls take the brunt of wind-driven rain, so the survey records exposure for each elevation before a material is chosen.

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