Successful cavity wall extraction demands expert knowledge and specialised equipment.

Whether for maintenance, repairs, or upgrading to a more efficient insulation solution, cavity wall extraction is a crucial service for maintaining a comfortable and energy-efficient home.

 

Why may you need this?

Remove your Cavity Wall Insulation

Prevent Damp & Mould

Old or poorly installed insulation can trap moisture within your walls, leading to dampness and mould growth. Removing the compromised insulation helps maintain a dry and healthy living environment, preventing structural damage and health issues.

Improve Energy Efficiency

Over time, insulation can settle or degrade, reducing its effectiveness. Extracting and replacing old insulation enhances your home's thermal efficiency, resulting in lower energy bills and a more comfortable indoor climate.

Avoid Structural Damage

Retained moisture within cavity walls can weaken the structural integrity of your home. By removing ineffective insulation, you prevent potential damage to the walls and foundation, ensuring the longevity and stability of your property.

Upgrade Insulation Quality

Advances in insulation technology mean newer materials offer better performance. Investing in cavity wall extraction allows you to upgrade to modern, more efficient insulation, improving your home's overall energy performance and value.

The Process

How to Remove Cavity Wall Insulation?

Complete the entire project in approximately two days for an average 3-bedroom detached property.

Step 1

Insert a compressed air line into the cavity wall.

Step 2

Attach a flexible suction vacuum by removing a single brick below the air line to collect the fallen insulation.

Step 3

Use the air line to push compressed air into the wall, breaking up the insulation and directing it towards the suction nozzle.

Step 4

Safely extract the damaged insulation material from the cavity.

Step 5

Remove the vacuum and air line & restore any holes and gaps in the wall.

Good work all round, all questions answered promptly and thoroughly, folks knew their stuff and were careful to check the best possible result given existing bits of broken polystyrene in the back wall. Larger than average 3 bed semi done in about 3.5 hours once they were set up. More aesthetic than practical, but I was particularly pleased with how well they matched the morter to the existing one for filling the holes at the end of the job. 25 year warantee was a particularly nice touch. Came sooner than booked due to a cancellation which was a bonus. Really noticing the difference already.

The 2 engineers did an excellent job of keeping the drilling holes to a minimum and cleaned up very well afterwards. In addition to the cavity wall insulation, they also had to fit a new vent due to our wood burner in the living room. They checked with us throughout the project that we were happy with what they were doing and asked for feedback at the end. Very professional and polite guys. We will hopefully learn over the hot summer and cold winter how effective the work has been. Well done team!

Terry Dunford did the surveying for our property he was very knowledgeable and gave very good advice which we check and was correct in everything he said. The men who came do the cavity wall insulation were also very good, they respected us and our home,they explained what they were going to do and warned us about the noise. They cleared up after they had completed the work and asked us to check that we were happy with the way they had left our property which we were. We would highly recommend this company to anyone thinking of having any cavity wall insulation done .
