I had some damp issues in my kitchen and I was worried I had a leak in my roof - I am so glad I had Simon over to check the issue. It turned out it wasn’t the roof and there were relatively straightforward fixes for the problem. He also went through all other damp related issues at my property and provided very practical and to-the- point advice to mitigate the issues. I can strongly recommend Simon to anyone who has damp problems in their property - he is very knowledgable, uses technology effectively and explains the issues in a clear and solution focussed manner.

As a private person it was difficult having a survey recorded in my home, but Simon has been very accommodating with my concerns and requests. The visit was interesting and helpful. Thank you Simon for your advice and responding to my many emails!

Ich möchte diese Bewertung gerne auf Deutsch verfassen, da mir das bei diesem doch recht komplexen Thema leichter fällt als auf Englisch. Schon vor dem Kauf unseres Hauses hat uns das RICS Level 3 Gutachten große Sorgen bereitet. Es wurden unter anderem eindringende Feuchtigkeit, eine angeblich defekte Hohlraumdämmung und eine fehlende Horizontalsperre festgestellt. Auf Empfehlung unseres Hausmaklers ließen wir die Feuchtigkeit von einer Firma begutachten, die Sanierungsarbeiten für mindestens £3.500 empfahl. Zum Glück entschieden wir uns nach dem Hauskauf noch für ein UNABHÄNGIGES Gutachten von Damp Surveys - rückblickend eine der besten Entscheidungen überhaupt. Simon und sein Team waren von Anfang an freundlich, professionell und zuverlässig. Die Kommunikation war ausgezeichnet und wir hatten jederzeit das Gefühl, eine ehrliche und objektive Einschätzung zu erhalten. Simon und Rob nahmen sich viel Zeit für eine gründliche Untersuchung und erklärte alle Zusammenhänge verständlich, anstatt vorschnell teure Maßnahmen zu empfehlen. Dabei stellte sich schnell heraus, dass unser Haus gar keine Hohlwände besitzt und die angeblich defekte Hohlraumdämmung somit gar nicht existieren konnte. Außerdem konnte Simon die vorhandene Horizontalsperre nachweisen und bestätigte, dass es keinerlei Hinweise auf aufsteigende Feuchtigkeit gab. Damit widerlegte er die teuren Sanierungsvorschläge vollständig. Statt unnötiger Arbeiten zeigte er die tatsächlichen Ursachen unserer Probleme auf. Der muffige Geruch in den Küchenschränken wurde beispielsweise durch Kondensation verursacht, und auch andere Auffälligkeiten konnte er nachvollziehbar erklären. Statt kostspieliger Sanierungen erhielten wir praktische, wissenschaftlich fundierte Empfehlungen zur Belüftung, Feuchtigkeitskontrolle und Schimmelprävention. Dieses Gutachten hat uns vermutlich mehrere tausend Pfund an unnötigen Sanierungskosten erspart. Noch wichtiger war aber die Sicherheit, endlich zu wissen, woran wir wirklich sind. Wer einen unabhängigen, ehrlichen und äußerst kompetenten Sachverständigen für Feuchtigkeitsprobleme sucht, ist bei Simon und dem gesamten Team von Damp Surveys genau richtig. Vielen Dank für die hervorragende Arbeit - wir würden uns jederzeit wieder für Damp Surveys entscheiden!

If you believe you have a damp problem or, as in my case, an inscrutable surveyor was reporting a damp problem, you must seek Simon's help. Not only is Simon one of the most straight-talking people I know, but as an authorized expert witness he operates with the upmost of integrity. I live in Australia and was selling my house in South London. You can imagine my anxiety when a surveyor reported a rising damp problem. The reported costs were astronomical and my buyer was spooked and on the verge of pulling out of the sale. I enlisted Simon's help and within a couple of weeks he'd prepared a report -based on real sensor data- and photos which proved beyond doubt that the house was not suffering from rising damp. As a result, the buyer was re-assured and proceeded to completion. I whole-heartedly recommend a chat with Simon about any damp related issue!

If you've noticed damp in your property, I'd definitely suggest speaking to Simon before committing to any work. We had two damp-proofing companies come out to inspect our house and neither correctly identified the cause of the problem. Both recommended installing a damp proof course in our basement, with quotes ranging from £5,000 to £10,000. It turned out the real issue was drainage problems — a blocked pipe and some leaking pipework were allowing water to get underneath the floorboards. The damp proof course they suggested wouldn't have solved anything, and our floorboards would have continued to rot. Simon took a very thorough and methodical approach and was able to identify the source quite quickly. He didn't jump to conclusions or try to sell us a particular solution. He simply investigated the issue, explained what he was finding, and told us what needed fixing. It was an education watching him work through the possible causes. We learned a lot about how damp behaves in older properties and feel much more confident about looking after the house going forward. In the end, Simon saved us a significant amount of money by helping us avoid unnecessary work. Because he's independent, we felt we could trust his advice. In contrast, the other companies seemed focused on selling their own services. I would highly recommend Simon to anyone trying to get to the bottom of a damp problem rather than just being sold a treatment.
