Carpentry- 21 Nov 2016
George designed, built, installed a set of custom-made doors for under my stairwell. Lovely guy, very courteous and pleasant to have around, and the work was precise and pleasing. I had one or two tweaks I needed done to the doors after the job had been completed which he helpfully came back and did for me. Happy to recommend him.

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!)

Bricklaying- 21 Sep 2021
Terry has done a really lovely job on our difficult garden wall. The wall was bowed and leaning in several places and in danger of collapse. We didn’t want to rebuild the entire wall due to the costs involved so we were looking for a builder who could improve what we had and make it safe. Terry used his expertise to suggest some fixes and eventually we settled for a rebuilt section plus a creative solution to one section that was skewed. The team arrived early and worked hard all day. Terry was keen to re-use bricks that were already on site which fitted in with the existing wall structure and also suited our preference of environmental responsibility in recycling resources. It was a long day but the lads worked hard to get finished in one day instead of two, which was the original estimate. All mess was cleared up and driveways hosed down and we are delighted with the finished result. We may have other hard landscaping jobs to do in the future and I will certainly be inviting Terry to quote for the work as he is diligent, an excellent craftsman and a knowledgeable tradesman. Highly recommended.

Latest review:
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.

Repointing- 14 Jun 2024
Joe and his Father are straight dealing, competent, honest and reliable. They did a very good job at a reasonable price. Joe's Father has decades of experience and knowledge and Joe had plenty of energy to attack the job. A third member of the team came in on the second day to help finish the job. A great combo! Repointing around the brickwork of 8 x windows with repair and repaint to window surrounds and masonry. Arrived on time! Finished on time! Cleaned up! Did the job to a high standard. This is not to be taken for granted in this trade and I had a couple of other chancers quote for the job who tried to phase me with very silly high prices at more than double the reasonable job value. So my recommendation is that you have Joe around to offer an honest quote and give this team preference and priority as a safe and satisfactory benchmark to get it done without fear of being ripped off or of having bodgers on the job. RECOMMEND RECOMMEND RECOMMEND!!

Richard did quite extensive refurbishment in record time, including two showers and new wooden floors and he is super reliable, very skilled and efficient, thinks ahead and works really hard, I am very pleased we hired him. We then commissioned him to build a garden office which is great, built to schedule and budget, bespoke and really lovely. Have recommended him widely and will continue to call him when we need work doing.

Extensions- 12 Dec 2025
We couldn’t be happier with the extension work carried out by Martin and his team. From the initial consultation through to completion, everything was handled with professionalism, care, and excellent attention to detail. Communication was clear throughout the project, timelines were met, and the quality of workmanship is outstanding. It was incredible to see the build go up in under 3 weeks. I couldn’t believe how efficient Martin was, everything moved like clockwork and this is testament to him being a true professional. The team was reliable, tidy, and respectful of our home at all times. The final result has exceeded our expectations and has completely transformed our property. We would not hesitate to recommend them to anyone considering building or extension work.
