Insulation- 28 Feb 2023
A Great British company who I will call first for all future work. I have multiple properties and seen many traders. Workmen never give compliments to others but two of my regulars were there and both told me his work/team were very good. DBMP treat the work like it is their own property. Good quality work, neat, thoughtful of other workmen/tenants, took all the rubbish away. No mean feat as he replaced skirting & floorboards, installed rock wool and rubber mats, re-fitted carpets, painted woodwork and moved furniture in & out; all while I had tenants in the house. This site is a gamble but I highly recommend this team.

Extensions- 20 Jan 2014
We are so happy we chose to go with Iver construction to do the extension of our home. We shortlisted a few construction companies but liked the way that Mr Sanghani came over to explain their quote and went through how they would go about the job and was able to answer all the small questions I had about how I wanted things to be done. Very professional. The team was also very professional and very hard working. Everyday there would be some sort of noticeable work. they are a tidy team and would tidy any mess made. Obviously with all the dust that an extension can cause there was still some dust left but they cleaned up as much as possible which we appreciated. The communication with Mr Sanghani was very good. He would always pick up the phone when I called or call me back if he was busy no matter what time or day. After the job was completed when I had a few minor problems like cracks they came back to fix these . Even whilst building if there was something I did not like they would do their best to make changes. All in all very good, friendly and hard working builders. I have already recommended them to loads of my friends and family. Can not fault their construction skills.

Restoration & Refurbishment- 19 Apr 2025
Positively, certain aspects of the finishing, particularly tiling, were carried out to a good standard. However, the overall experience was mixed due to significant issues. There were notable challenges during the project involving basic logistics and site management, leading to considerable inconvenience that seemed avoidable. Furthermore, the quality of workmanship was inconsistent; while some parts were good, other areas involving fittings and fixtures showed a lack of attention to detail in the finish, requiring later adjustments. Communication during the process could also be difficult, particularly regarding problem-solving and planning for materials. While we appreciated the parts done well, the project was let down by these inconsistencies and process issues, leading to some ongoing snagging and disappointment.

Extensions- 17 Nov 2025
Freddie, Kaz and Dan are a great team. I felt they were friendly and professional throughout. Any slight niggles were discussed and solutions found, quickly and professionally. They were respectful and went out of their way to get on with all the neighbours. Over all I would say they are a team of very nice people, who care about what they do and take pride in achieving the result their clients are after.

Victor (Vica) laid some engineered oak wood flooring for us in a house that we bought at the end of 2013. The house needed lots of work doing and the new flooring was just one of the many jobs undertaken by Victor and carried out to a very high standard for us. He always paid attention to detail, ensured that the flooring was level and that the new skirting board fitted flush to the floorboards. He was also always able to provide a solution to any problems encountered during the renovation works. I would have no hesitation in recommending Victor as he takes the same pride in his work for others as if he was carrying out work in his own home.

Ahmad and the Beam Developers team did an amazing job on my rear extension. We were very particular with our requests and are generally picky people but they were very patient and accommodating to our every request. We were shown the drawings, made adjustments and managed to tailor the project exactly to what we wanted. The finished results were amazing. No big project for us soon but should we plan to do the loft will definitely use Ahmad and his team again.
