Should I get cavity wall insulation?

Here at Extract Insulation, we know that deciding to undertake work on your property is a complex one. We regularly handle queries from a range of customers, including these frequently asked questions.

Is cavity wall insulation suitable to all properties?

No. There are some conditions that means cavity wall insulation is not always suitable for a property. For this reason, we always carry out extensive assessments before recommending the right service to you. Having cavity wall insulation installed when it isn’t suitable for the property can cause a range of issues, such as damp or structural damage.

The property may also affect the type of materials that can be used to fill the cavity.

Why have cavity wall insulation installed?

Within homes the walls and loft are the main source of heating loss. Insulation provides an extra barrier, preventing the warm air from escaping as much. As a result having cavity wall insulation and loft insulation can dramatically reduce household energy bills. It will also improve a property’s EPC rating, which can in turn raise property value and ensure the home meets basic energy efficiency standards.

There are many reasons why the insulation in cavity walls may be removed.

In some cases, it may be installed incorrectly or a property may not have been suitable in the first place. It’s also possible for damage to cause problems with the insulation, such as damage occurring to the external brickwork

Many problems with insulation stem from the insulation becoming damp. This not only means you don’t receive the maximum benefit of the insulation but it can cause further issues to. Properties that need their cavity wall insulation removing are likely to experience damp and mould inside, for example.

We also receive mails from troubled home owners who are looking to know about the cost of cavity wall extraction. The cost obviously varies from one project to another, depending on the size and need of the house. I am providing a very rough and basic idea on the cost.

Well, our service for a semi detached 3-bed property would be something like £1,300 – £2,000 while it would be £1,000 – £1,500 for one three-bed bungalow.
