Existing insulation and guarantee check for Leeds properties

Our West Yorkshire coverage takes in Leeds (LS1) and nearby Morley, Pudsey and Lofthouse. Leeds is one of the main towns we cover in West Yorkshire.

Every inspection point in Leeds is photographed and logged, so you have a record to show a buyer, lender or contractor. Buyers and sellers in Leeds often book this check when a survey report or EPC raises questions about the walls.

Local weather affects which walls can be filled. West Yorkshire has a mix of moderate and more exposed sites. Hilltop, coastal and west-facing walls take the brunt of wind-driven rain, so the survey records exposure for each elevation before a material is chosen.

For regulations, if cavity wall insulation follows in Leeds, 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.
