Cavity Wall Insulation Inspection Services - CIT

Cavity Wall Insulation Inspection

The problems of damp and condensation are a serious cause for concern for Local Authorities and Housing Associations all over the UK. The causes can be numerous and getting to the bottom of it can be costly. All too often, these ‘solutions’ merely involve remedial work based on visual only inspection and the use of a damp testing meter, and this type of analysis may not get to the root of the problem. You need a reliable, unbiased authority to help you make the right decisions in each individual case.

Here are some examples of problems recently investigated by CIT:

The consequences of incorrect installation

This property in Harrogate was inspected due to damp appearing in the kitchen 3 years after the home owner had CWI installed. Company A carried out its own survey’s installs, including the post inspection, effectively marking its own homework and has now gone out of business. The guarantee supplier referred the liability back to the Energy company who originally funded the install and asked to have an Independent inspection report done on the property.

Our investigations found that the damp was caused by a parapet wall which was not sealed, allowing water to ingress into the cavity below. The property was in a bad state of repair with cracks all over the render and no D.P.C.  The install should not have proceeded until these issues had been addressed. As a result, the cavity walls in the property had to be cleaned to allow the property to dry out and ensure suitability for re insulation.

The consequences of incorrect diagnosis

The home owner requested an Independent Inspection because a local builder had advised that CWI was the cause of a damp problem that had appeared around the patio door in the lounge.

Our investigations found that the CWI was dry inside the cavity. After further inspection, we also discovered that the window seals were in poor condition, and all that was needed was for the offending window to be re-sealed, after which the lounge wall dried out and there was no recurrence of dampness.

As you can see, there’s plenty to look out for when making important property decisions, and the above are just two examples of how easy it can be to be miss-informed and take the wrong course of action. As well as providing independent investigation services, CIT also run a series of training courses designed to provide Local Authorities and Housing Associations with a solid, fact based understanding of what to look for, so that when they are dealing with problems related to cavity wall insulation, you make the right investment decisions for local housing stock.
