Bathroom Fitting- 24 Oct 2025
We had 2 bathrooms refurbished at the same time by Romulus and his team over a 4 week period. Both bathrooms were completed on time and on budget. We were looking for 2 functional bathrooms, but ended up with 2 very high spec bathrooms within our original budget, and couldn't be happier with the high level of service and professionalism by all his team. We will now move forward and have his team refurbish our kitchen.

Conversions - General- 7 Feb 2022
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.

Ged is the perfect builder for someone who does not know what to do, who to trust, or what you might need to do to achieve your ambition. We have used many different trades people, ranging from cowboys to good workers that rip you off. Ged was better than anyone we have used before. He is open, really kind, easy to talk to and most importantly professional. And definitely not a rip off. He priced the job really well, it really was amazing for what I got. He help with loads of advise, worked hard and to a good time table. I cannot express how happy we were to have Ged on our job. He and his team had amazing attention to detail. Polite and helpful. I look forward to having Ged Work on future projects soon. You are in good hands. High praise, but Ged deserves it. If you want someone you can trust, do an excellent job and be easy to communicate with, Ged’s your man.
