Damp investigation after cavity insulation in Luton

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

Damp investigation after cavity insulation for Luton properties

If your property is in Luton or the LU1 district or nearby Dunstable, Leighton Buzzard and Ampthill, it is within our Bedfordshire coverage. It is roughly 18 miles south of Bedford.

We never cold-call in Luton or anywhere else, and we do not work with doorstep claims companies. Where a Luton 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.

Wind-driven rain is the first thing the surveyor weighs up. Much of Bedfordshire 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.

As for paperwork, if cavity wall insulation follows in Luton, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Rules in England

Filling a cavity is notifiable building work and needs a building notice or competent-person self-certification if insulation work follows.

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.
