Bricklaying- 19 Apr 2018
Brett is a nice guy and does do very good brickwork. There were good and bad times... We agreed a payment structure of all material and then money at the end of each week when that stage was completed. It was a disjointed build but he was always asking for more money for the next stage when the previous hadn't been finished. Part way through the build he stated he had taken a job elsewhere and now could not do the next stage (knockthroughs) At this point we had paid him up to and beyond what had been completed but he said he had no money to finish the last bits. After texts asking for the last £1000 because he was so hard up. I agreed to transfer it on the basis he complete the last bits. He never came back as promised. I have since had another builder come in and they have pointed out errors with the work. How the new extension bridges the cavities. These have had to be rectified else would cause damp. Towards the end of the build it was clear our build was not his priority. When he failed to show up when he said he would. I googled his name and previous companies registered to his address. 4 brickwork companies all dissolved. Do your research! I would recommend him for small jobs but not a big build.

Latest review:
Thegreenorigin Ltd worked on a full refurb of our office wash rooms in August last year. We had moved into new offices that had been completely renovated with the exception of the bathrooms, which were 20 years out of date! As a busy recruitment specialist in central London, we have an enormous amount of footfall through our offices on a daily basis, including those through our bathrooms, so the quality and resilience of the work was imperative. Thegreenorigin took time to understand our business priorities and worked throughout the night to allow us to maintain use of the bathrooms while they were doing the job. It meant we could still provide facilities to our clients (and staff) whilst they were being refurbished. This was a very important factor for us. In addition to this, they worked around issues which came to light regarding the building we worked in and old pipe work that was still in place, causing sewage issues and completed the project within the timeline we agreed. I would have no hesitation recommending them to other businesses or personal customers.

Hard Flooring- 23 May 2026
I can’t recommend them highly enough. We ended up hiring them for bathroom renovation including tiles, sub flooring rework, decorating. They maintained a great level of communication, were on time and completed according to the estimated timescales and budget. I would not hesitate to hire them again. We will keep in touch with them to have our patio done over the next year.
