Damp investigation after cavity insulation for Downpatrick properties
We cover Downpatrick and the BT30 postcode district, including nearby Newtownards, Banbridge and Bangor. It is about 22 miles south of Bangor.
Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Downpatrick properties, so you can choose who fixes them. Where a Downpatrick 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 Down 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.
For regulations, if cavity wall insulation follows in Downpatrick, inserting cavity wall insulation needs a building control application to the council before work starts.

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.
