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.  As accredited members of OSCAR, 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.  Update your home with a beautiful exterior paint or weather coating finish, providing you with not only a smart finish but protection for your home against the elements and damp issues.  All work is carried out to the highest standard and we always ensure that the finish is of the quality you require. 

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.

Fencing can both provide essential security and a smart finish to any garden area or commercial space.  We offer a wide range of styles from traditional wood, to composite and metal fencing, all installed by our experts.  We will work with you to provide the design and finish that you require and ensure that the materials we use are of high quality and built for longevity.

To provide customers with top quality home maintenance and improvement provisions delivered with first class customer service and care.
