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.

Ivan and his team completed a full loft conversion at our terraced house, and we couldn’t recommend them more highly. They did a fantastic job from start to finish and were a pleasure to work with. Communication and project management throughout the project was excellent, and their commitment really showed. Nothing was ever too much trouble to ask. The project was completed within the estimated timeframe, which was especially appreciated as it finished just before Christmas. The team was very considerate while working in our home, and we stayed in the house for the entire duration of the project with minimal disruption. In addition to the loft conversion, they also replaced all our doors with fire doors and installed new flooring throughout the house, all to a very high standard. We’re absolutely delighted with the results and would highly recommend Ivan and his team to anyone considering similar work.

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.

We've been seriously impressed with Pawel and his team. They opened up our rear dining room/kitchen wall using an RSJ, following our engineer's drawings perfectly. They also did a few bits of plumbing and bricked up one of the windows at the rear, which is where the new kitchen will be fitted. They were incredibly tidy and really pleasant and courteous to be around, which my wife was so grateful for given we live in a busy family house (most builders are not like this...), I can't thank them enough! We will definitely be using them again in the not-so-distant future!
