Cavity cleaning and debris removal for Grantham properties
If your property is in Grantham or the NG31 district or nearby Stamford, Spalding and Lincoln, it is within our Lincolnshire coverage. It is roughly 22 miles south of Lincoln.
Where a Grantham 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. If your Grantham installation has a guarantee, we check it first; the guarantee route may cover the work.
Exposure matters for every cavity wall. 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.
On compliance, if cavity wall insulation follows in Grantham, 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.

Why debris matters
A clean cavity lets water that gets through the outer leaf drain away. Debris piled at the base or caught on ties makes a bridge for that water. It is a common cause of damp low on walls and around ties, with or without insulation.
