Existing insulation and guarantee check for Grimsby properties

If your property is in Grimsby or the DN32 district or nearby Cleethorpes and Scunthorpe, it is within our Lincolnshire coverage. It is roughly 30 miles north-east of Lincoln.

The written result for your Grimsby property is plain English: what we found, what it means and what, if anything, to do next. Buyers and sellers in Grimsby often book this check when a survey report or EPC raises questions about the walls.

Before any material is chosen, exposure is checked. 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.

In terms of approvals, if cavity wall insulation follows in Grimsby, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

How to tell if a house already has cavity insulation

Look for a regular pattern of small patched holes in the mortar joints, often about a metre apart. Check the EPC, which may say 'filled cavity'. Ask the seller for a guarantee. The reliable answer is a borescope check, because patched holes can be from a fill that was later removed and EPCs are sometimes wrong.
