Suitable properties for cavity wall insulation

Most properties built after 1935 have cavity walls. The majority of properties will be suitable for wall insulation. However certain types of houses are not suitable such as, timber framed, concrete houses, steel framed, and other system built houses. If your property suffers from damp, your surveyor will need to determine what type of damp you have.

 

If your home has black mould on cold external walls then cavity wall insulation may help. If your home has a problem with penetrating damp then cavity wall insulation will not be suitable. Penetrating damp can be either coming from below the ground or across the walls. Penetrating damp doesn’t appear as black mould but the plaster will be bubbling and coming away from the wall. Your surveyor will give you further advice.

How it's installed

Before cavity wall insulation is installed, a survey needs to be carried out to ensure that your property is suitable for cavity wall insulation. If your home is suitable, your home assessor will make all the necessary arrangement to get the work carried out. This includes completing all paperwork to claim the grant. If your assessor deems you are eligible to have the work done free then you pay nothing at all and the grant is paid directly to the appointed contractor once you sign to completion form saying that you are happy with the work.

 

The work in most cases is carried out all from the outside. Small holes, around 22mm (about the size of a 10p coin) is drilled through the mortar joints. The insulation is then blown in. The holes are then made good with matching mortar.

 

If your house is rendered then your installer will have to drill directly through the rendering. Some companies will touch up the holes with a similar coloured paint if it is of a standard colour such as white, cream or magnolia. If your home is not one of these standard colours then you may need to supply the paint or make arrangements in the future to get it touched up yourself. If we come across a rendered property we will always try to put you with an installer that will touch up the paint work.

 

All installers on the scheme are approved by the British Board of Agrement (BBA) and offer the 25 year guarantee issued by the Cavity Insulation Garantee Agency (CIGA).
