Damp investigation after cavity insulation for Ampthill properties
Our Bedfordshire coverage takes in Ampthill (MK45) and nearby Bedford, Dunstable and Leighton Buzzard. It is about 7 miles south of Bedford.
We never cold-call in Ampthill or anywhere else, and we do not work with doorstep claims companies. Damp in an insulated Ampthill home is not always the insulation's fault, so the diagnosis comes before any extraction.
Local weather affects which walls can be filled. 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.
On compliance, if cavity wall insulation follows in Ampthill, 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.
