Damp investigation after cavity insulation in County Tyrone

Damp investigation after cavity insulation across County Tyrone, priced before you book, with the findings written up and photographed. 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 across County Tyrone

We cover 4 towns in County Tyrone: Omagh, Dungannon, Cookstown and Strabane.

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.

Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for County Tyrone properties, so you can choose who fixes them. We never cold-call in County Tyrone or anywhere else, and we do not work with doorstep claims companies.

Building control in Northern Ireland

In Northern Ireland, inserting insulation into an existing cavity wall needs a building control application to your council before the work. We make sure the application route is agreed and confirmed in writing before any drilling starts.

Sources: Building Control NI: frequently asked questions; Belfast City Council: what are the building regulations.

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.

What is included

  • Moisture mapping inside
  • External defects check
  • Borescope at affected areas
  • Cause and options in writing
