Painting & Decorating- 13 Nov 2025
The team did a solid job on our extension. They were on time, kept the place organised, and stayed easy to reach throughout the project. The extension came out exactly as agreed and the finish looks clean. They also took care of a few extra jobs for us, including painting the exterior, laying new slabs in the garden, and putting down new grass. The whole place looks tidy and well put together now. I would be happy to use them again.

Extensions- 30 Nov 2020
A really excellent set up of builders. Peter was great in evaluating the work and what we needed done. Sue was clear in her communication on costs, and then execution of the works by Taras and his team was superb. The extension was built in fantastic time-frame, and the end result is great. The work-ethic of the builders is what really makes them so good. They are on-time every day, and relentless with working hard each day.

We had the pleasure of working with Alfa Style Limited on our loft conversion and we can recommend them highly and without reservation. Their work is incredible, attention to detail outstanding – our build was done with care and precision. They turned up on time every day, worked incredibly hard and quickly. In addition, they were extremely clean and tidy in the workplace – they never left the worksite in disarray. This is the first time we have done such a big project – Ruslan, Slava and their team were amazing. They were brilliant at explaining what was going to happen, day by day, week by week and translated the more technical information! No question or query was too much. The service after the build had finished has also been great, calls to check everything is OK and any queries we have, they are only a phone call away. We have had so many compliments from family and friends who have seen the finished build … it has made a huge difference to our house, we could not be happier.

Gus and Frank were brilliant. Their attention to detail and care for our project was evident. There was already an issue with our floor which Gus and Frank rectified for us before doing the tiling. The final finish was immaculate. We liked their work so much that we also got them to fit our kitchen worktop. Good communication and clarity throughout the job. Would definitely recommend!

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.

Tiling- 24 Sep 2025
I hired seasouth builds because not only did he give a really reasonable quote, but he also had knowledge of tiling over retrofit underfloor heating - which other tilers seemed to be really hesitant to work with. The job was done to an excellent standard - he’s a real perfectionist. It did take a bit longer than expected, due to some floor level issues which he didn’t account for when he quoted. I was really worried about the price increasing out of my budget when we started running over time, but I was so grateful to find that he was a really honest guy who stuck to the agreed quote and didn’t try to make it my problem one little bit. He was polite and friendly throughout the whole job, turned up whenever he said he would, and kept in constant contact. Really honest (I happily left him unattended in my property). Customer service was excellent, nothing was too much trouble. 10/10 would recommend.

Kitchen Fitting- 7 Jan 2021
My experience with Leszek was entirely positive and I wholeheartedly recommend him. I had recently moved property (converted victorian flat) and required a new kitchen installed, shelves built, radiators replaced, painting throughout and some changes to electrics. The work was undertaken around October 2020. Leszek completed the work to a very high and professional standard and I am really happy with the end result. He was easy to get on with, good natured and commutative which made the whole process easy and less stressful for my first experience in home improvements. Leszek was always happy to answer all my questions and further explain the fine detail from electrics to kitchen installation. When small problems arose, he always had a couple options ready to discuss and called promptly to keep me up to date. The kitchen installation is perfect which also included tiling a backsplash. Lezek built some lovely selves in the recesses either side of my fireplace which look brilliant and very smart. The painter and his work was really professional and speedy. Snagging was dealt with and two neighbours independently and proactively commented that the work was done with minimal disturbance to them. From quote to completion it was all in all an excellent experience!
