Remedial work and loft conversion. Dan / LR did a fantastic job at converting our loft space into a lovely storage area, after a previous (unrelated) tradesman damaged our home. They stripped out the previous work and built in new reinforced floors etc. Dan and his team are highly experienced, knowledgable, professional, kind and helpful. They also managed the communications with Structural Engineers and Building Control incredibly well and took the stress away from us. I strongly recommend. 10/10. Couldn’t be happier with the quality of workmanship and customer service / support. Transparency and clear communication from quote to on-time completion. They really went the extra mile and were very empathetic with the challenging circumstances we were in at the time. Dan is the only builder I will use and recommend going forward.

Kitchen Fitting- 9 Oct 2016
Chris came over and seemed very professional, however, since then I know he's not. Chris quoted us a 4 weeks estimate for the works, however took 10 weeks all in all. Chris said he would have someone on site to work every day and that he wasn't doing others jobs, however days went by with no works carried out and he was really hard to reach at times. Since the jobs been completed he is now holding me ransom for extra pay for works he claims I haven't paid for which I have (and some of this work were repair jobs to damages him and his men caused). I have had 2 plumbers out since to fix leaks and both have called him a cow boy. He hasn't returned my house keys and wont give me my gas certificate (and also tried holding back the electrical certificates at one point - which I went behind his back to get). It was cash-in-had so no tax for him to pay. He is also now threatening me with legal action. The guy is a JOKE. DO NOT USE!

Bathroom Fitting- 23 Aug 2019
Very professional. Arrived on time and the two young men did a very good job and tidied up afterwards. A little more expensive than the other quotes we had but I felt that I could trust Lee who came to price up the job which is why we chose this company. I would definitely recommend them and hope to use them again in the future.

Chris and his team completed a large ground floor extension to our 1930s bungalow, along with internal modifications. Chris was reliable and kept us informed about the progress of the build at all times. He was polite, helpful, trustworthy and a tidy worker. Living on site during the build it was really important to have good people around and everyone Chris bought to site also did a great job. We are really pleased with the end result and would recommend Chris for any building works! Would happily use him again.

Extensions- 13 Nov 2019
Mark managed the whole job (which was complex and involved three different rooms; change of use and new build) effectively and efficiently and engaged family members and friends in various trades as needed. With extensive experience Mark was able to make suggestions and put forward many ideas to improve the basic plans that we had which was most helpful. This included raising a ceiling level to a better height than we had envisaged possible and removing the need for a pier so that a wall could be flat throughout the new kitchen. Mark has a good eye for the aesthetics of a job. He is also very amenable to adding on extra smaller jobs in the process and even procuring some materials that I wanted in order to do something myself ! The workmanship and finish is high quality for a competitive price. I would not hesitate to recommend Mark and have, in fact, already done so for another couple of potential jobs. Finally, Mark is a really nice guy and great to have a chat and cup of tea with (two sugars!)
