WHY REMOVE CAVITY
WALL INSULATION?

With over 11 million properties around the UK having had cavity wall Insulation installed, the benefits speak or themselves. However, our damp climate can take
its toll on brickwork, leading to both external damage and water leakage. If left untreated, prolonged water penetration can affect some types of cavity wall
insulation and may result in damp problems affecting inner walls. If mineral wool insulation becomes permanently damaged, the only real solution is to remove it.

The damaged cavity wall insulation material is removed as unobtrusively and cleanly as possible. Compressed air is blown into the cavity while an industrial vacuum collects the damaged insulation from the bottom of the wall through strategically removed bricks.

A boroscope is used to inspect the cavity throughout the process to ensure all damaged insulation has been completely removed. The old insulation is then bagged up and removed, while all the brickwork is made good.

There are several different types of cavity wall insulation on the market, and the cost and difficulty of removal can vary depending on the type of insulation present in your home. Removing Blown mineral fibre Insulation Mineral fibres are rigid, water repellent insulation materials most commonly used in exterior walls. Although they have strong insulating properties, they can cause major issues if incorrectly installed.

If the material is blown at the wrong pressure or an incorrect drill pattern is used, homeowners can be left with large cold patches and voids in the wall where heat can escape and damp can sneak in.

Damp problems are the main reason customers call us for cavity wall insulation removal. It is usually caused by poorly maintained exterior brickwork, severe exposure to wind and rain, lack of protection from other buildings and trees, or a combination of the three. Also with the recent spell of flood weather once cavity wall insulation is wet it must be removed from the property as quickly as possible.

Damp, deteriorated or poorly installed cavity wall insulation can have major negative consequences for your home, from unsightly damp and mould to increased energy bills as a result of inefficient heat retention..
