Damp investigation after cavity insulation in Omagh

Omagh 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 Omagh properties

Our County Tyrone coverage takes in Omagh (BT78) and nearby Strabane, Cookstown and Dungannon. Omagh is one of the main towns we cover in County Tyrone.

If your Omagh installation has a guarantee, we check it first; the guarantee route may cover the work. Where an Omagh 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.

Local weather affects which walls can be filled. Parts of County Tyrone 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 Omagh, inserting cavity wall insulation needs a building control application to the council before work starts.
