Hear from homeowners like you…

This Birmingham homeowner hired Kooka Developments to put right their cavity wall insulation:

My experience with Kooka was excellent. The cavity walls in my home had been filled back in 2010 as part of a government grant project to insulate houses. But as the years went by we started noticing serious cold spots around windows and corners.

I asked Kooka to investigate. They inserted cameras and we saw that the existing insulation was sparse and had failed in multiple places. They returned later and filled the walls properly. The work was done neatly and the site was cleaned before they left. I am very happy with the result.

Reasons for cavity wall insulation removal

Knowing why your cavity wall insulation needs removing in the first place is the first step to fixing the problem.

Here are the four most common reasons for cavity wall insulation removal:

1. Compacted or degraded insulation:

Over time, some insulation materials can settle or compact, leaving gaps that reduce thermal efficiency and allow moisture to accumulate.

2. Pest or rodent damage:

Rodents and insects can burrow into insulation, creating holes and gaps that compromise performance and lead to damp spots or drafts.

3. Moisture penetration:

Water seeping into walls from leaks or rising damp can saturate the insulation, reducing the insulation’s effectiveness and creating conditions for mould growth. Poor installation can be the root cause – which brings us to…

4. Substandard installation work:

Tell-tale signs of a botched insulation job include poor ventilation or missing or exposed insulation, which can all cause damp and mould.

What does cavity wall insulation removal involve?

Thankfully, the process of removing cavity wall insulation is usually a relatively straightforward. It involves:

1. Survey and assessment – A qualified inspector checks your walls and insulation for signs of degradation or damage

2. Safe extraction – Old or damaged insulation is carefully removed through small drilled holes in the walls using a vacuum extraction system. Sound messy? It’s generally a fairly tidy process (as long as you hire right!)

3. Wall treatment – Damp walls are dried and treated if needed

4. Optional replacement – You may choose to upgrade your insulation to improve your home's energy efficiency

Did you know?...According to the Government's Department of Energy and Climate Change (DECC), making energy-saving improvements to your home increases the value by 14% on average – and up to 38% in some parts of England.

How can I tell if my cavity wall insulation needs removing or replacing?

If you have noticed problems with a damp build-up in your home, the cavity wall insulation could be the culprit. It’s a good idea to get the issue checked out by a cavity wall insulation specialist first, before going ahead with cavity wall insulation removal. It could be that something else is to blame.

How long does it take to remove cavity wall insulation?

It usually takes between one and three days to remove cavity wall insulation from an entire home.

Will my walls need drying after removal?

Yes, if there is damp present, your walls will need drying after the removal of the insulation. Specialists often combine removal with wall drying and treatment.

Is cavity wall insulation removal covered by home insurance?

Usually, cavity wall insulation removal is not covered by home insurance, unless damage was caused by an accident, such as a water leak. If in doubt, check your insurance policy details.

Can I remove cavity wall insulation myself?

Removing cavity wall insulation is a specialist job. We recommend hiring a specialist contractor, as they’ll have the skills and experience to remove it quickly and with minimal mess.

Does cavity wall insulation devalue property?

Cavity wall insulation doesn’t usually devalue a property when it’s installed correctly. In fact, it can make a home more energy-efficient and attractive to buyers.

However, if the insulation has been poorly installed, it could cause issues like damp, mould, or structural damage – and this may reduce your home’s value. In these cases, you may need to have the insulation removed before selling.
