Zen came round to see job and returned competitive quote quickly. He was able to start a few days later, turned up on time and completed the works with the designated 2 day time frame, working essentially 2 full days (not my experience of builders in UK who are only onsite for 5 hours a day). He cleaned up the site and did a good job. Would use him again.

Hector and his team did a full renovation of my 1960s flat, including boiler, central heating, electricity, bathroom, kitchen, plastering of walls, floors, and painting. From the start Hector impressed me with his attention to detail. He suggested good improvements to the original plans, and had solutions to problems that had stumped the other builders I had been talking to. I trusted Hector to delivery premium quality rather for my home and his team lived up to that expectation. The plastering was especially good. Hector is well organised and advised to have every little detail written down so we can ensure we were on the right page. Along with clear timelines for when materials needed to be ordered for this kept everything running smoothly, and the build completed on time. Hector's man Wilson managed the team day to day. He was always polite, friendly, and helpful when I dropped by to see how the work was going. There were a few small snags after the build (perfectly normal and to be expected for this kind of work) and Wilson and his men sorted them out quickly without any hassle. No complaints from me, I would recommend Hector and his team for your home renovation.

Wonderful work by Conrad to make a small box room into a decent size bedroom by demolishing our existing brick wall between two bedrooms and replacing with a stud work one. Removal of all the rubble, plumbing, electrics and plastering were included in the work and it was all done cleanly and swiftly. I would recommend Conrad highly, he's a lovely chap and very reliable

I can highly recommend Wayne and his team for their recent work. Our job was the conversion of our home from two flats into one house and the job included: - removal of artex and re-plastering - removal of partition walls and re-building of new room corner and door rehang - building spindles and links etc on wooden staircase - fitting electrics: switches and pendants - fitting trims and replacing moldings to match those damaged by previous conversion to two flats In terms of price, I found their quote to be competitive - not the highest and not the cheapest but we chose them as we were impressed by Wayne's attention to detail when he came to look at and price the job. This approach continued throughout and ensured that we were very clear on costs and detail of each element of the job. Also impressive was the job timeline - the team started the day we agreed and finished a day early! (This is a first for any builders we've hired!) And in turn, when it came to the follow-up snags (of which there were just a couple and one was down to faulty product, not an error in build) Wayne was very quick to respond, getting back to us within 24 hours on a weekend too! I will definitely invite them to quote again.

Great job undertaken, all work completed to a high specification and quality. The workers always discussed any items that came up to make sure I got what I wanted. In specing up the job William was very helpful and proactive in assisting me finding the right materials (specific bricks in this case) and managed getting all materials to site in these tricky times. Work areas were always left clean and tools stored away (important with young children) Wouldnt hesitate to use again for any other building works.

External Works and Repairs on Large House for Freeholder We had hired Chiro to complete External Works and Repairs on the Exterior of a building that comprised 2 flats on behalf of the Freeholder. From the outset Octavian and his crew were very professional to deal with in terms of negotiating the price, start date and the works to be completed. The project involved repairing brickwork, roof tiles, ridge tiles, parapet walls, pointing, facia, plaster work, fixing windows/sills and finally sanding and painting etc and required a comprehensive repair of the exterior of the building. Much of the work was quite intricate and required careful repair of damaged areas and often coming up with creative solutions to get a good finish. The workmanship and attention to detail was very impressive and even involved them doing online research to find an alternative to old ridge tiles that were no longer available. Any issues or additional requests that arose were favourably received and dealt with immediately. The project started and was completed on the agreed dates and the site was left clean and looking well. Overall I would highly recommend Octavian and his crew to other clients.

Ermir, Vlad and the Nami team are not only skilled craftsmen, they’re trustworthy and incredible to work with. They turn up on time, they stick to their promises, they proactively communicate to make sure you’re up to date, and they are joyful lovely guys to be around. There were problems with my project due to my building being old & some things being unforeseeable but with every hurdle they came up with practical solutions to make it work. The situation could have been incredibly stressful and upsetting, but Nami worked with me every step of the way with great kindness & a can-do attitude. The final result is gorgeous - even my downstairs neighbours love the work Nami did for me. I cannot recommend them more highly, hire them, you won’t be disappointed.

DBM Contractors have been excellent! Having moved home, had structural work and general renovations done 3 times in the last 10 years, Orgest and his team have been by far the best we’ve experienced and we certainly will not look anywhere else in future. Once we agreed on the schedule of works and price, during which time the communication was polite, clear and consistent, there was a plan set out and the timeline to start work was precise and adhered to. He deployed the right number of people from day 1 - they work at speed but with clear quality and without shortcuts. As a result, we were further along than we expected within the first few days alone. Naturally, we added some work along the way - the communication around this was clear and we felt like we were involved in every step. They shared the smallest of details during the job so that the decision making was a combined effort. The level of communication, politeness, general friendliness and openness to help from the whole team has been very good. As we’re waiting for better weather, all but 1 job has been completed and we are very happy with the finished product – we wholeheartedly recommend DBM contractors for any work you are considering.
