I met Charlie and his team from CM Builders Ltd when they were completing a loft extension and ground floor extension for one of my neighbours. Quotation and budget I was given an estimate subject to drawings as I was on a strict budget that I had to keep to for the build. Charlie was able to help me keep to the budget, both at the final agreed plan and during the build. The project was complex in that whilst it was a loft extension, all of the house was rebuilt. The only thing kept was the external walls and first floor rafters. Whilst the footprint of the first floor was not being changed I wanted to bring it up to current building standards with extra insulation. All of the plumbing and electrics were also replaced including a new boiler. The overall build has come in on budget, save for agreed enhancements that I did not think of at the planning stage and or building regulations such as double ceiling fire plaster boards. There were also items such as the original stairs that I wanted to keep, but Charlie was able to increase the height space in the kitchen making the worktop much more usable for tall people for a larger part of the kitchen. These were suggested to me as potential options as part of the build. Stage payments The stage payments have all been sensible throughout the build and linked to the ongoing work schedule. I have not therefore had any concerns in this regard. Quality of work This was a very complicated build as unlike the ground floor the first and new second floor are “L” shaped. The new 2nd floor included an en-suite and 2 bedrooms. Overall the house has been increased from 2 bedrooms 1 bathroom, to four doubles and 2 bathrooms. The quality of work is excellent and Charlie project manages his team to ensure that they all deliver to a high standard- if it is not done correctlt they do it again, with Charlie spotting any issues. Timeline of build This has generally gone to plan very well. As with any build you have to be realistic as things will happen outside of anyone’s control. When issues have arisen Charlie manages them to a conclusion. Also be realistic if you are having to manage to a tight budget. I had to plan for various stage receipts of cash before I could order the kitchen and bathroom items - make sure you understand how this impacts the build and availability of the work force, recognising that CM Builders have to book kitchen fitters and plumbers. CM Builders are also very helpful in that they have sorted out issues with the brick work of my freestanding garage (nothing to do with the build) and also a neighbour’s wall that could have been dangerous to the public, should it have failed. Conclusion The whole family are very pleased with the outcome and we now have the equivalent of a brand new house that has been built to a very high standard. This has definitely been worth doing both from a valuation perspective and quality of life perspective. I would not hesitate to instruct Charlie and his team again.

Extensions- 17 Jan 2018
A Total disappointment Ricky agreed to install a porch and roofing. He advised us to install new pvc doors agreeing to fit the roof after. This started mid November with a promise to be completed before Christmas. On his instruction we paid other workers to complete the preparation works and then the morning of the Job he sent a text message advising that he will no longer be able to attend the job. Thankfully we were able to find a local reputable roofer -plasterer-tiler who completed the work to a very high standard I feel very let down as I had put total trust in his promise to complete the work. Unfortunately based on this I cannot confidently recommend Ricky to a friend family, or anyone else.

Plastering- 16 Mar 2020
Almed and his team came over to see the two bungalows and gave me a quote and was more reasonable than other quotes I had previously. Almed started the job and stated exactly what he was going to do from the beginning to the end of the job. He is a very professional and knowledgeable person and he and his team did a outstanding plastering job on my two bungalows and I’m very happy with the job and will highly recommend him for future projects. Thanks Zai

Painting & Decorating- 12 Feb 2019
He truly showed professionalism that I had struggled as a guest house operator to get from handy people. He would go out of his way to satisfy. The finished redecorated room project was a masterpiece and took a little longer than planned because of the weather but he gave it his all! I am pleased I took a chance on him as there was no review on his profile when I hired him. I would however, pay attention to work and point out issues as they come up otherwise, you will have dirt and rubbish to content with as the workers leave all the mess after work.
