Damp investigation after cavity insulation for St Neots properties
Our Cambridgeshire coverage takes in St Neots (PE19) and nearby Huntingdon, Cambridge and Peterborough. It is roughly 16 miles west of Cambridge.
Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for St Neots properties, so you can choose who fixes them. Where a St Neots 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.
Every elevation is judged on its own exposure. Much of Cambridgeshire 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 the rules side, if cavity wall insulation follows in St Neots, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

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.
