Damp investigation after cavity insulation in Lincolnshire

Damp investigation after cavity insulation across Lincolnshire, 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 Lincolnshire

We cover 10 towns in Lincolnshire, including Lincoln, Grimsby, Scunthorpe, Boston, Grantham and more.

Wind-driven rain is the first thing the surveyor weighs up. Much of Lincolnshire sits in the more sheltered driving-rain zones of the UK, which widens the choice of fill. Exposed elevations, coastal sites and high ground still get checked wall by wall.

Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Lincolnshire properties, so you can choose who fixes them. If your Lincolnshire installation has a guarantee, we check it first; the guarantee route may cover the work.

Building Regulations in England

Filling an existing cavity wall is notifiable building work in England. Either a building notice goes to building control before the work, or the installer self-certifies it through a government-approved competent person scheme such as CIGA's CWISC scheme. The insulation used must also be suitable for the wall it goes into, which is why the survey checks construction, condition and exposure first.

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.
