What customers say about cavity wall insulation removal

“First class service from start to finish, survey carried out the day after an enquiry was made, a thorough inspection of the cavity wall with a camera. Work personnel were extremely efficient and performed a difficult job between two houses with very limited access, which a previous company arrived to do and turned away saying it was not possible. The work was completed in a relatively short time, half a day, very tidy, leaving no trace of any cavity wall insulation around the garden.”

“I can't recommend more highly. Had initial problems with previous company but over the phone and indeed at my home they made my life easier and sorted everything the previous company couldn't.”
Steven B·Hampshire
“Great service. I wouldn't choose anyone else to help sort my damp in my house. Having asthma doesn't help either, so Extract Insulation Limited turned into a real life saver!”
