Cavity Wall Insulation Removal
Cavity wall insulation is the most cost-effective method of reducing fuel bills – but installed incorrectly it can cause expensive problems.
It can lead to damp developing and the cost of rectifying this can outweigh the savings made.
House-builders began regularly constructing properties with cavity walls from around 1920, and two decades later it became standard industry practice.
But poor wall cavity insulation can cause an array of problems. Damp can lead to crumbling plaster and fungal decay, and later to more serious structural and timber erosion.
Increasingly rain-lashed winters have resulted in an increase in reports of damp issues in properties. A likely cause of damp is the bridging of the cavity by the earlier installed insulation material. Moisture penetrates into the cavities – more noticeably on weather prevailing walls – and damp gradually builds over the years as the insulation material becomes saturated.
Bluebell Nothwest takes a proactive role to prevent damp occurring. By using machinery which blasts compressed air into the cavity walls, the problematic debris and old insulation is removed. It is usually possible to drill through old holes in the brickwork where the original insulation was inserted.
The debris blown out of the cavity and collected in bags fixed to the external wall. The whole process can be completed within two days – depending on the size of property – and with minimum disruption and mess.
