ABOUT Cavi Clear Ltd

Industry leading cavity wall insulation removal, damp proofing and property renovation experts offering our services across Wales and the South West.

What sets us apart? 

We remove your cavity wall insulation following the safest, most effective process, which does not cause any further damage to the property,  utilising industry-leading equipment and technology, our highly skilled technicians adhere to industry best practices to ensure that their work is always of the highest quality.  All our team members are fully qualified and regularly audited to ensure the maintenance of first class working practices and customer service. We strive to provide a friendly, smooth and cost effective solution from initial survey to provision of our Certificate of Guarantee. 

We are very aware that simply removing faulty cavity wall insulation is a major solution to damp problems, however, if you have other damp issues that require rectifying, our damp proofing service is second to none. We will carefully assess your property to establish the type and cause of the damp you are experiencing and provide you with the best solution to solve the issues.  All jobs are carried out to the highest standard and we always ensure that you are satisfied with our work. 

Wall ties are another hidden area that many home owners are not aware can fail or cause issues.  Over time, cavity insulation that has become saturated will effect the integrity of the wall ties, causing them to rust and fail.  We have many years experience at replacing wall ties and will ensure that the completed work is both structurally sound and the external aesthetic finish matches your existing finish.

We provide a comprehensive range of waste removal and disposal services, rather than hiring a skip, call us for a quote with the added benefit that our friendly, efficient team do all the work for you!


We work in partnership with an established financial service - Priors Mortgages, to provide suitable options for funding solutions.  Once you have confirmed your intent to engage us, we will provide your details to Priors who will contact you directly to discuss your options.
