FAQs
How long does it take to remove cavity wall insulation?
It usually takes between one and three days to remove the cavity wall insulation throughout a whole house.
Can I remove cavity wall insulation myself?
Just like with the installation of cavity wall insulation, removal is a specialist job. It’s recommended to call in specialist contractors, as they have the skill and expertise to remove insulation quickly. A professional also uses the most advanced extraction equipment. This means they can remove all cavity wall insulation without any damage to the walls or the rest of the property.
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 an expert first, before going ahead with cavity wall insulation. It could be that something else is to blame.
You should also watch out for signs (or sounds) of vermin living within the cavity wall insulation. This can cause damage to the insulation, as well as not being very pleasant to live with.
Lastly, you may want to consider replacing your cavity wall insulation if you find that it’s not working very efficiently. If your heating bills are still higher than you’d like, a home insulation assessment could recommend upgrading to a higher performance cavity wall insulation product.
