I had a survey carried out to determine the cause of the damp and felt happy with this being a thorough exploration. I subsequently received a report with recommendations. Unfortunately since then the communication has been very poor. I have being trying to finalise the recommendations, I have sent emails, made calls requesting a call back and emailed the main office, all with no response. I am left with holes in my bedroom floor from the investigation works and have lost faith in works being resolved." > — Customer in Surrey (5.0, via Which? Trusted Traders) > "I have always returned to Advanced Preservations, after the need to find an experienced, reliable local Company, when I had major problems with groundwater flooding, several decades ago. A pump system was installed, after careful listening and appreciation of my concerns, due to my small Grade 2 Listed cottage, which has no Damp Proof Course. They quickly came to solutions for the unusual site. All the staff who carried out the more complicated work than usual, were cheerful, very hard-working and a pleasure to have in the house. The pump system saved me from flooding a week ago, after the latest 'named' storm, which flooded many in my village. Over the years I have called on them for dry-walling work, after some damp was revealed; and recently (2023) to resolve ongoing problems with condensation. I recommend the Company at every relevant opportunity. for the excellent, careful work, on site and in their efficient Admin. Office, where inter-personal skills are immediately appreciated." > — Customer in Hampshire (5.0, via Which? Trusted Traders) > "I wanted to say how pleased I am with the damp remedial carried out recently at my home. Paul did a great job with installing the damp course and plastering work and he was a pleasure to have in my home. Likewise Ollie did a brilliant job replacing the skirting board lovely young man. I was very comfortable having both of them working in my home both good representatives of Advanced Preservations." > — Customer in Surrey (5.0, via Which?
