Dampness is often misdiagnosed by contractors.
Quite often the correct solution is simple and inexpensive.

Highly professional and detailed service
Customer Service
Jason was incredibly helpful both when requesting information about his services and explaining the final report. He answered all my questions with detailed answers and fast-tracked the report getting it to me several days ahead of expectation.

Professional, thorough and reassuring recommendations
Customer Service
I contacted Jason to complete a damp survey and give us a second opinion following a very scary quote we received from a so called "damp expert company" which recommended us to damp proof all rooms for the cost of 60,000 pounds!!!! We had just bought the flat less than 3 months prior and during our general building survey as part of the purchase process, no damp had been identified so we were terrified with this quote and the huge work recommended!. Since the same company who completed the "assessment" would also carry out the work, we decided to get an independent second opinion by a trusted person registered with PCA. I am so happy that we found Jason from JPM Independent Surveyours. He was professional from start to end completing a thorough investigation, explaining the process and then advising of achievable life style and other affordable recommendations. His verbal recommendations at the end of the survey were followed by a clear report at the end of the same day I would higly recommend Jason to anyone that having discovered condensation and mould in their house want to understand the cause of these and receive trusted and effective recommendations so that it does not spread and deteriorate further.

Detailed damp survey, easily contactable and great advice
Customer Service
I hired Jason for a damp survey on a property I suspected there was damp in. Jason gave very quick responses and acted in a professional manner. If there were any emergency issues with the booking, he would let me know immediately and suggest alternative times which was very impressive. He turned around the report in a short amount of time and gave detailed advice to me to fix particular issues as well as advise on how to look after the property and prevent damp. Would highly recommend to anyone looking for a surveyor. One of the most professional experiences and would certainly use again in future when required. Thanks Jason.

Excellent service, highly recommended.
Customer Service
We have had an offer accepted on a property and asked Jason to do a damp and timber inspection for us. From the first communication Jason was extremely responsive and was even willing to offer weekend dates to accommodate our timelines. He inspected the property and produced a highly thorough and professional report on the same day. He noted all issues identified and helped us prioritise what to fix based on the severity of the defects. After submitting the report, Jason continued to respond to all our follow-up questions in a very timely manner. Couldn't be happier with the service, we highly recommend JPM.

Damp survey
Customer Service
Jason was prompt, professional and efficient. His report was very detailed and with clear recommendations and independent. I would recommend him highly as these traits are difficult to find in a tradesman who was found without any personal recommendation. Definitely recommend highly.

Fast responsive service and comprehensive work
Customer Service
Jason was able to do a damp and timber inspection for us quickly and we got the report back within 2 days. He gave a very comprehensive report with a lot of specific recommendations about what to do. Compared with a damp report from a nationwide vendor Jason's report was a lot more comprehensive. Definitely recommend.

Damp survey
Customer Service
Jason was on time and set out clearly what he would be doing. He was wearing the relevant Covid kit. He covered all the areas I needed checking and when relevant explained the issues thrown up and possible solutions, showing me photos where access was difficult. The detailed report came back within 24 hours.

Endorsement Reference Very happy customer
Customer Service
Jason responded quickly to my request for a damp survey. He listened to the issues we were having and completed his surveys. He was familiar with our area and the type of building we are in. He quickly diagnosed the issue and talked us through his findings and made recommendations for fixing the issue. He then sent through a thorough report with pictures and also a list of products he recommends that we use. We were very happy with his work and explanations and solutions he provided. We would highly recommend Jason.
