Addressing the Problem, Not Just the Symptoms

Addressing the Problem, Not Just the Symptoms

Damp and wall defects can have more than one contributing cause, particularly where cavity wall insulation has become saturated or wall ties have deteriorated over time. Our approach is to assess the property carefully, understand what is happening within the building and identify the remedial work that is appropriate for the underlying problem.

Arrange the Right Survey for Your Property

Whether you are buying, refinancing or simply need a professional survey, we can help you choose the right service for your requirements. Surveys for refinancing or property purchase are £150 + VAT, commercial surveys are priced individually, and all other surveys are provided free of charge.

Built on Confidence

We stand behind the quality of our cavity wall insulation extraction and wall tie installations with a free 25-year company guarantee, giving customers long-term reassurance once the work is completed. For wall tie installations, an insurance-backed guarantee through the Wall Tie Installers Federation (WTIF) is also available as a chargeable option for customers who require additional protection.

What Our Customers Say

View all reviews
“I had a fantastic experience with Cavi Clear Ltd and honestly couldn’t recommend them more highly. From the very first contact with Rob, communication was easy, friendly, and professional. Responded quickly and arranged to come out to my home to look at the cavity wall issue in person, no guesswork, just a proper assessment. It gave me a lot of confidence that they wanted to fully understand the problem before quoting. I received a quote the very next day. It was clear, and well explained, with no pressure or hidden extras. What really stood out was how they went out of their way to fit the job in on our preferred day, which made a big difference for us. On the day of the work, they arrived on time, were polite and respectful of our home, and explained exactly what they would be doing. They worked efficiently and kept everything clean and tidy throughout. You can tell they take pride in their work and genuinely care about doing a proper job rather than rushing through it. It’s rare to find a company that combines great communication, reliability, flexibility, and high-quality workmanship, but Cavi Clear Ltd delivered on all fronts. If you need cavity wall cleaning, don’t hesitate — these are the people to call.”

“Cavi clear Ltd We required installation removal from cavity walls. Cavi Clear Ltd provided an excellent service, clean, quick and very reliable. They explained the whole process to us, job completed with 3 days and photos supplied. Would highly recommend.”

“The guys at Cavi Clear are reliable, fast and efficient workers. They get on with the job and leave the site clean and tidy before leaving each day. The work was completed to a very high standard and I was very impressed with the end result. I would definitely recommend them.”

“We had an incredibly helpful guy from Cali Clear come out to give us a quote for CWI removal. It was evident that he knew exactly what he was talking about. We had received a previous quote from another company, and not only were Cavi Clear better value, they had mentioned a few things (such as that they would add a brush to stop the CWI from moving from the unaffected wall to the front - as we only wanted one wall done) - which was really reassuring, and gave confidents that the job they would have done would have been a good one. He was quick, yet thorough to quote. By chance we happened to discover an undisclosed guarantee in place with CIGA for our recently purchased property, who will remove the CWI as part of their agreement, and whilst we did try to ask them if they could use Cavi Clear, they have had to use their pre-aprooved company - and I was disappointed that we won't be needing Cavi Clear for their services as I am certain they would have done an incredible job. Would highly recommend.”

“Literally was a nightmare finding a reputable company to do cavity wall insulation removal. Someone I know recommended these guys and Im very glad of it! Every other company I found seemed dodgy or had bad reviews or was stupidly expensive. These guys were absolutely spot on fair play. Easy to deal with, professional and polite. Didnt recommend a ton of other unnecessary work for the sake of it. Would definitely recommend them to anyone.”

“Great communication from Rob and his team. Cavi Clear’s quote was 50% lower than another we had. The team on site were friendly and considerate. They had a couple issues with a hired compressor (out of their control) but went above and beyond to source a new machine to get the job done, working late to finish that day. Would recommend.”
