I was recommended the company and first impressions were good. 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.

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.

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.

Advanced preservation has been servicing our sump pumps for the last 4 years. They always do a honest job and I would definitely recommend them!

We have used Advanced Preservation twice. Once for a basement, waterproof tanking, and also put a water pump in. The other time was for outside, drain away, taking slabs up and relaying. From start to finish on both jobs Advanced Preservation have been excellent, tidy, always reliable and kept us informed at different stages of the jobs and kept to schedule. I cannot recommend them enough and I will always use them in the future.

Had my sump pump servicing again by AP. Easy to organise, gave me a date that was shortly after I’d emailed to ask for the service. Technician was knowledgeable, polite and talked me through the key points of what he was doing. Very reasonable pricing and very happy with the work. Will use again for the next service!

I recently had full waterproofing of my basement and I was very happy with the service provided. Initially Dave conducted a thorough survey and provided a waterproofing design recommendation and detailed quotation for a cavity drain membrane system. Dave was very professional and knowledgeable and the quote was very competitive compared to other quotes I received. I ordered the work and this was all completed this summer. Everything was done on time, on the dates promised, with the price exactly as quoted with no extra surprises. I found all of the operatives on site to be very professional and they took great care installing everything while looking after my property. My previously wet and damp basement is now perfectly dry and I have been very happy with the performance of the waterproofing system so far. I definitely recommend this company and would happily use them again in the future if needed.

Advanced preservations fixed several areas of damp in our basement flat. They were easy to deal with, did a really good job, kept the place clean and followed up with any queries quickly.
