Damp investigation after cavity insulation in Thurso

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. In Thurso the visit is priced up front, and any follow-on work is quoted separately so you can choose.

Wind-driven rain is the first thing the surveyor weighs up. Parts of the Highlands and Islands 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 Thurso, no building warrant is needed for insulation within a wall, but the work must meet the building standards.

Rules in Scotland

No building warrant is needed for insulation within a wall, but the work must meet the building standards if insulation work follows.

Sources: Scottish Government: building work not requiring a warrant (schedule 3).

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.
