Extensions- 5 Nov 2016
Leslie carried out the following works: chemical damp injection to walls on rear extension, reroute down-pipe, repair fracture on rear wall, install gutter hedgehog. Hopefully, this will resolve some of the issues we had with damp, a blocked down-pipe and an overflowing gutter. Leslie arrived on time on the first day but was delayed a few hours the next day. However, the work still was done within two days as expected. Thank you!

Extensions- 25 Jul 2023
Vini and his amazing team became part of our family for the months they were working on our house! Attention to detail and great communication was a top priority for me before starting our large scale renovation, and they delivered above and beyond on every front. Vini’s team helped transform my vision into a reality - they weren’t thrown or intimidated by any of my crazy/creative ideas, and were equally ready to advise and bring constructive ideas of their own to the table, based on their years of experience. We would highly recommend Olaj Brothers as trustworthy, professional and highly skilled tradesmen.

Plumbing- 4 Aug 2026
Gareth arrived early, identified the issue and was really prompt in fixing it. He was very clear in explaining what the issue was and showing me how he fixed it. We also had another issue in the bathroom and he was able to identify it and give tips on how to manage it in the future. I would definitely recommend him and have saved his number in case of the need for future work. His also provides guarantees for his work which gave me alot of peace of mind. Thanks again!

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.

Conversions - General- 4 May 2025
I Hired Em to do my ground floor reno, which included a garage conversion and remodel of my kitchen where 2 internal walls were removed. Very glad I found Em to do the job. Him and his team was efficient, friendly, tidy and hard working. We encountered obstacles along the process (which is normal for any renovation) but Em gave his opinion, listened and we came to the best solutions. Very happy with the result. Em is a reliable, punctual, knowledgeable, fair, down to earth guy and one of the best if not the best contractor I have hired. Highly recommend. Some before and after pictures.

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.
