Jerzy carried out several jobs for us. He has completely refitted our bathroom, he's rebuild a wall, laid front of house path, restored old front door, installed solid wall internal insulation, rebuild window frames, plastered a room and few other bits and pieces. He is extremely reliable and trustworthy. He's always been on time, works really hard and has always been honest about things and up front with any issues. Always consulted us for possible solutions. His work is to the highest standard and if I want a job done well, I always go to Jerzy.

Florin was hired to put up a partition wall between our living room and kitchen and he and his team did a fantastic job. Really quick to respond, were able to do the job on time, on budget and to an excellent standard. The new wall, the electrics and the finish are all perfect and our flat was left spotless. Couldn't ask for more and Florin was always available on his mobile if we had a question. Would definitely use 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.

A great experience. Work was completed quickly and to a good standard with an unexpected extra (sorting out the electrics for a light in the crawl space). Most tidy builders I have ever employed. Quick responses and good communication. I'd happily use Prime Contractors again

Extensions- 23 Dec 2022
ELB Construction completed some major garden works for me and constructed a garden office. It was a big piece of work with a lot of earth moving, significant foundations and a lot of brickwork. The ELB team, specifically Jimmy the site manager, were fantastic, always giving me the right advice about things I was not knowledgeable about, always focussed on a quality finish and flexible when we had some challenges with our neighbours. The finish is great, communication was always open and honest and they were very competitively priced. My brother in law is in corporate construction and was specifically very impressed with the quality of the brickwork that Jimmy and the team produced. Thank you to the whole team!

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.

Danny and the team (Scott, Darren, Dayne, Dennis) were fantastic, consistently working to find more effective, lower cost solutions. We enjoyed working with him so much we then took on a significant amount more work with him, that involved a full fit out of a fitness studio. Danny has a wide network of individuals with many areas of expertise he can call on when necessary. In a couple of the really difficult moments of the project Danny went over and above what you would expect. We were delighted with the work and will be recommending him going forwards - although I’m sure everyone wants his time!

Pawel worked on my son's property in Notting Hill, London. The final result was absolutely wonderful. I found Pawel incredibly helpful, skilful and willing to change things last minute, as I procrastinated over every job! He left the property clean and tidy each day, and the end result was a flat that has been transformed and improved beyond recognition. I would thoroughly recommend Pawel and will definitely use him again in the future.
