Good communication all time around. However, the survey required some corrections which has been rectified quickly. Recommend this company.

Lielis Andrews2025-05-23Trustindex verifies that the original source of the review is Google. Quick and efficient service. Would use again. Timely visit to property and survey provided within 5 working days. Excellent communication from start to finish. SALINDER PATEL2025-05-23Trustindex verifies that the original source of the review is Google. Great service, did everything they could to ensure i got this within the timeline. Customer service was 5 stars, kept me updated all through the process. Definitely be using them again. Deborah Dunkley2025-05-21Trustindex verifies that the original source of the review is Google. I chose this company after reading their trust pilot reviews. Initially I spoke to Amber who was very knowledgeable on the telephone and was able to speak to me in technical terms which was reassuring. A survey was arranged and carried out for the approaching weekend. Aslan carried out my Survey and he was thorough. I have now instructed them to go ahead and submit my plans for building regs and I know my project is in good hands. Yasemin A2025-05-09Trustindex verifies that the original source of the review is Google. I recently used paramountbuilt for a structural survey on a property I was purchasing, and I couldn’t be happier with their service. From start to finish, the team was professional and thorough. They provided a detailed report that was easy to understand, highlighting all the key findings and offering clear recommendations. Their expertise and attention to detail gave me complete peace of mind during the buying process. Valentina Ljubchinskaja2025-05-08Trustindex verifies that the original source of the review is Google. I applied for a house extension with Paramaunt Build and submitted a planning permission application through the council. At the start, Sophie and Zoe were very nice and helpful. Later, Sumet came on board and did a great job with the painting. I had a few amendments, including some that came after the application had already been submitted, but the team was always accommodating and made the changes as requested — they were truly kind and supportive throughout. Amber helped speed up the process, and I was told that hopefully by 8th May, the council would approve the project. And today, on 8th May, Amber called with the great news — my application has been approved! Right now, we're halfway through the process with the company, and the next steps will be with the building control department. I hope that part goes just as smoothly and efficiently. Once the whole project is completed, I’ll be happy to leave a detailed review. Thank you, Paramaunt Build team! Robert2025-04-29Trustindex verifies that the original source of the review is Google. The Engineers report was very thorough and his visit was prompt. It took a while for the local Council to get their act together, as they kept trying to find faults, but this is down to their employing sub standard employees. Paramount acted very quickly by answering their problems with facts and calculations. It is rather embarrassing when local councils take out their discrimination of tax paying citizens in full view of a professional tradesman and Company brought in to give a comprehensive report. Remember, the extra costs £600 have been borne by myself, personally the council should be sued for wilful obstruction. Paul Chappell2025-04-25Trustindex verifies that the original source of the review is Google. Was quoted incorrectly from the start, I was clear on what was needed. But we got there in the end, had design work for 2 steels and joist plan.End product is okay, communication was poor through out. I had to chase all the time to get completion. Got what needed in end. Annie Wheeler2025-03-27Trustindex verifies that the original source of the review is Google. We used Paramountbuilt for some drawings and calculations for the removal of a chimney and the chimney breasts on the lower and upper floor of our home. Their quote was very reasonable for a surveyor to come out and a structural engineer to then give us detailed drawings and calculations to assist the builder and for the local authority regulations. The service I received from the team during phone calls I had, was also very helpful. They have lost one star from me due to some payment confusion, but it was all sorted in the end.
