Posted on Jessica BrodrickJune 29, 2025 I recently engaged Daniel for a Level 3 survey on a property I am buying. He was incredibly helpful. On the day he completed the survey he shared his initial findings over email, and then took the time to have a call to discuss them in detail. He followed up with the full report which presented all his key findings well. I would definitely use Daniel again.Posted on michael proctorJune 26, 2025 Daniel provides a great surveying service. A ‘top man’. He surveyed a flat in a Victorian building for us. His verbal and written report were completely comprehensive and so easy to understand. He described all the issues found and explained the importance and relevance of each. He included an estimate of repair and improvement work should we decide to make improvements which has left us with a priority list to inform our ongoing development of the property. I would recommend him without reservation. If we move again (hopefully this will be our last and forever home) we will be using his services.Posted on Edvyn Andy WongsoJune 25, 2025 Daniel recently completed a building survey for us. Communication is very clear and efficient from the beginning. Daniel is very responsive to any queries we have. We received a summary on the same day after the survey was done. The full report was delivered on time as promised. It was comprehensive and detailed. As first-time buyers, we had many basic questions since we had no experience with construction. Daniel answered all our queries with a clear explanation and assurance. He is knowledgeable and able to recommend solutions for every issue. We are satisfied with Daniel's service and will definitely recommend him to anyone. Daniel will also be the first person to contact when we plan for an extension in the future.Posted on Anna SpreckleyJanuary 16, 2025 Daniel is fantastic! Incredibly knowledgeable, trustworthy and efficient. He adds a human touch too, which makes you feel like he genuinely cares about you and your property. Very thankful that we have used him as we know we’re in good hands. Highly recommend him!Posted on Stephen AireyAugust 14, 2024 Yeah, we're really pleased that we got Daniel to survey a potential property before purchasing. He wasn't only thorough and knowledgeable, but was also on hand to answer any questions we had and chat afterwards. We wouldn't hesitate to recommend him to anyone looking for a survey, or any other services he offers. Thanks Daniel!Posted on Sara GalbiatiMay 15, 2024 Can't recommend Daniel enough. We have recently had a full structural survey completed for a 1930s property we are in the process of buying. From our initial enquiry to the many questions we had once the detailed report came through, Daniel has been quick to get back to us and very thorough in his analysis and recommendations. Worth every penny.Posted on N ThorntonMarch 23, 2024 Excellent. Highly recommend. Prompt, clear information, great value for money.Posted on Hannah PritchardJanuary 31, 2024 Cannot recommend Daniel enough. He was extremely quick to respond and to complete the survey/ report. When I met with him to discuss the property he explained everything very clearly in layman's terms so that I felt I really understood the situation at hand despite being a first time buyer and having very little knowledge in the area. Daniel reassured me and gave me confidence to move forward and for that I can't recommend him highly enough.Posted on Odette MurtlandJanuary 22, 2024 We can highly recommend Daniel who has been incredibly professional, knowledgeable and responsive during a stressful time of dispute with a builder. He provided supportive and informed guidance following his site visit and was always timely in his communications. His report was thorough, detailed and well illustrated.Posted on Sara MendhamDecember 11, 2023 Daniel did a survey in one of our rented properties in York. He was very professional and produced a report quickly. He also answered all our questions regarding the building and helped us to find solutions to the problems. We will use him again and we recommend him to anyone that needs a good surveyor.
