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!

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.

Loft Conversion- 5 May 2017
Artjom and his team have done a wonerful job on our loft conversion and house renovation. We are very pleased at the transformation. Although not the cheapest quote we obtained, they were highly professional, kept the noise down and cleaned up after themselves. We also added several other jobs to our initial quote and they undertook these as requested. It is important to keep a record of everything you ask to be done. They worked very fast and were able to complete everything within 2 months - it helped that our house was empty at the time, so they didn't have to deal with us living there at the same time as the works were being carried out. Overall, I would highly recommend Adam Renovations for any building works you need done to your property.

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.

If you are looking for a caring and conscientious builder then look no further than Stephen. Not only is he on your side for your project and budget, he gets the job done with absolute attention to detail. He works incredibly hard and is not satisfied till you, the client, are happy. He has a photographic, encyclopaedic memory for all things building and structural. He, with his extensive experience, is worth more on your project than any architect plans or drawings. Not only is he damned good at what he does, he’s polite and thorough. He also has a fantastic team that he keeps a close eye on at all times. There are no loud radios or requests for coffee. His team have a fixed break/lunch, bring their own supplies and I’m embarrassed to admit, leave your house tidier and cleaner than when they arrived - even when doing excavation/structural work! I offer only one word of caution, once Stephen and team are in, you won’t want them to leave, and you will start asking him to do all those other building jobs you never knew you wanted done! You will be very fortunate if you can secure him for your project. You can complete confidence in him, his team and their work.
