Cavity cleaning and debris removal in Wiltshire

Cavity cleaning and debris removal is available throughout Wiltshire, from Swindon to Salisbury and Trowbridge, with the price agreed first. Cavity cleaning removes mortar droppings, brick rubble and builders' debris from the bottom of a cavity or from ties, where it can bridge the gap and carry moisture to the inner wall.

Bricks removed at the base of a wall so mortar debris can be raked out of the cavity

Cavity cleaning and debris removal across Wiltshire

We cover 4 towns in Wiltshire: Swindon, Salisbury, Trowbridge and Chippenham.

Before any material is chosen, exposure is checked. Wiltshire 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.

Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Wiltshire properties, so you can choose who fixes them. Damp in an insulated Wiltshire home is not always the insulation's fault, so the diagnosis comes before any extraction.

Building Regulations in England

Filling an existing cavity wall is notifiable building work in England. Either a building notice goes to building control before the work, or the installer self-certifies it through a government-approved competent person scheme such as CIGA's CWISC scheme. The insulation used must also be suitable for the wall it goes into, which is why the survey checks construction, condition and exposure first.

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.

What is included

  • Borescope check to locate debris
