Ryann and his team first completed a multiple room ground floor extension for us, including the installation of a new kitchen and bathroom. We were so pleased with the work that we asked him to build an outdoor garden room from scratch and completely refurbish our other bathrooms. We have always found Ryann to be friendly, punctual, knowledgeable and honest and I am more than happy to give my recommendation.

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.

Conversions - General- 30 Jun 2017
The project was a complete renovation of 2 bedroom period flat - adjusting internal walls, new kitchen, 2 new bathrooms, electrics, boiler, rads, new floor etc + full decoration. The Home Design & Build team were fantastic from start to finish - I'd give them 5 stars and would fully recommend. The quality of the work is outstanding - great craftsmanship and attention to detail + a very 'can-do' attitude to the bespoke elements and alterations that occurred throughout the project. The quote was clear and competitive, and the project stayed on budget aside from a few small additions to the scope which were added on at fair and transparent rates. It also stayed within the planned timescales (which is a first from my experience) and the team worked hard to complete on time. Both Lalli (who managed the project) and Mario (who led the work) were great to work with, highly capable and full of helpful and practical suggestions to the detail of the design.

Electrical- 14 Oct 2018
During the cutting phase of our ceilings, the insulation company had to stop the job and asked us to get the electric cables checked by a professional before they seal the foam. It was 6pm by the time I posted at MyBuilder and Rob was very responsive to help us understand whether there is a problem. He came and checked the cables the other day right on time, even talked with the insulation team himself to solve the technical issues. He was very proactive and full of advice and he tested all our electrical cabling system also the other day. We can not thank him and recommend him more. If you need urgent yet professional and friendly support Rob is the right contact. Thank you Rob!

They were not focused as working on different jobs at the same time. Window and plumbing was ok, but the painter was not recommendable. They fixed some shelves which fell next day. One of them came back to fix it but it fell again. They didn’t bother to come back .
