Cavity Wall Insulation Inspection & Survey

Our process is as non-intrusive as possible. We drill a hole in the wall to inspect the cavity with our small 8mm cameras. This will allow us to view the condition of the cavity insulation.

When the survey is completed, we will provide you with a detailed report, informing you of the work we have carried out, and what information we have obtained.

All our home property maintenance work is efficiently undertaken, with attention to detail. Work carried out on time and on budget.

Why Should You Remove Cavity Wall Insulation?

It is recently estimated that in the UK, more than 6 million properties have had cavity wall insulation installation.  Cavity wall insulation helps to save energy, however, due to the damp climate, high winds, and sometimes icy conditions, this takes a toll on the brickwork over time, causing gaps to open up in the bricks or in the pointing and water getting into the wall cavity itself. The telltale signs of this are cold spots on your walls or damp patches which are unexplained. This can cause very uncomfortable conditions to live in. Prolonged dampness can rust wall ties which are an integral part of the property, which can mean the outer and inner walls can separate. Do not ignore damp insulation, if you suspect your property of being affected, contact the team at ebm Wales today.

  • Rubble

Problems The Can Occur:

  • Damage to pointing
  • Wall tie corrosion
  • High Humidity / Fungus growth
  • Subsidence and perished Brickwork walls

Cavity Wall Insulation Problems Can Effect Your Health

When cavity wall insulation becomes wet, it can potentially soak up water moving across the cavity and then may affect the wall surface of your property. When your insulation becomes wet, it can be very difficult to dry out. This could cause dampness in your property, increasing your overall energy bills at the property. This could cause your property to be colder, and could then suffer from damp smells and mould. These problems can have a negative effect on the property and the residents of the property. The quality of air inside a property can become negatively impacted by the presence of dampness and mould. These problems can take years to develop even before you begin to notice them at all. Damp could be damaging your walls long before issues present themselves. Your energy costs could become much high due to your heating having to work that much harder to heat your property.

We use high tech equipment and machines to safely and quickly extract the cavity wall insulation without causing any further damage. Our qualified teams follow the best practices to make sure their work is always completed to the best standard.

How To Remove Cavity Wall Insulation

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 good.

The Proccess

The way which the existing insulation material should be removed depends on the type of insulation material which has been installed. The process tends to begin with the removal of bricks at the bottom of the wall to create pockets. Holes will then be drilled in the external wall in strategic positions. Using a cavity wall extraction system, the old insulation material will be sucked out of the wall. The remnants will then be collected in large bags. Our specialists will utilise a borescope to fully inspect the cavity throughout the removal process to ensure that the entirety of the damaged insulation has been removed. Once our specialists are satisfied that the cavity wall extraction process has been completed, the wall will be repaired. A clean the work area surrounding the property will then be completed to make sure that debris is removed.

Cavity Wall Insulation And Damp

One of the main reasons that customers call us for our cavity wall insulation removal service is poorly maintained exterior brickwork with a lack of protection, that has been exposed to the wind and the rain, this could be caused by the brickwork having no protection from other near by buildings or trees, etc. Some areas more than others throughout South and West Wales are more exposed the wind and rain and are more at risk of cavity wall insulation problems.

    I had EBM carry out a lintel replacement and damp proofing. They were brilliant from start to finish. They were clear in their quotation, kept me informed on a start date, turned up on time and got the job done on schedule and took every care in keeping my house clean. I'd highly recommend EBM

    Work is near completion. Chris and the guys have been brilliant - very considerate and hard-working. The job has taken a while due to the consistent rain we have had the last couple of months but Chris has kept in constant communication to update me on when work can continue. Highly recommend.


    Couldn't be happier with the work the team have done. So professional, friendly and have been amazingly flexible throughout the whole process despite a pandemic. Open, honest and always cleaned up. Would recommend anytime and will certainly be calling Chris again for future work
