Cavity cleaning and debris removal in Hampshire

Cavity cleaning and debris removal across Hampshire, priced before you book, with the findings written up and photographed. 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 Hampshire

We cover 18 towns in Hampshire, including Southampton, Portsmouth, Basingstoke, Gosport, Waterlooville and more.

Every elevation is judged on its own exposure. Hampshire 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.

We never cold-call in Hampshire or anywhere else, and we do not work with doorstep claims companies. Where a Hampshire 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.

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
  • Brick removal at low level
