Instant Extraction Estimator

Answer a few quick questions, pop in your details, and get your personalised price range straight away.

What type of property
do you have?

How many storeys is the property?

Failing insulation can cause damp patches, cold spots, mould, and rising heating bills, whatever the size of the property. The more storeys, the more wall area it can affect. Getting it sorted early usually means a simpler, cheaper fix than waiting for bigger problems to develop.

What kind of bungalow is it?

Failing insulation often shows up as damp, mould, or higher heating bills. Dormer bungalows can also feel it in the loft rooms behind the sloped ceilings. Either way, extraction and reinsulation usually takes less than a day, with minimal disruption to your home.

How many walls need extracting?

Each wall needing extraction adds to the job time and material removed, but most homes only need a handful done to make a real difference to comfort and heating costs. A rough count is fine, we'll confirm the exact number on the call.

Is this you?

When should you remove your cavity wall insulation?

Cold spots on walls

Patches that feel noticeably colder than the rest of the wall, even with the heating on.

Damp patches or mould

Damp appearing on internal walls, especially after wind-driven rain, is a classic sign of saturated insulation.

Musty smell indoors

A persistent damp smell that doesn't clear with ventilation, often coming from the cavity itself.

Rising heating bills

Wet insulation stops insulating. If your bills have crept up with no other explanation, it's worth checking.

Selling or surveying

A mortgage survey has flagged the insulation, or you want it sorted before the property goes on the market.

Switching insulation type

Moving to external wall insulation or a different fill means the old material needs to come out first.
