We chose SWLBC to refurbish a two-bedroom flat. This entailed complete redecoration, replacement of the flooring with a new engineered wood floor, moving old and installing new electrical sockets and light switches, running some new piping and replacing the heating system with a more modern and efficient one. The quote from SWLBC was very competitive and we are really happy with the quality of the work. The flat is transformed and it looks terrific. Ben Toone who is the proprietor of the company is very professional and helpful. He was easy to contact and responded to our questions quickly and thoroughly. We met some members of his team during the works and they are hard working and competent. They also cleaned up the site beautifully after they had finished. Thank you Ben and your team. We are delighted with your work and highly recommend SWLBC.

We initially hired Michael to convert a bathroom into an office. After meeting him and discussing our longer-term plans, we quickly felt confident moving forward with him on much wider renovation works across the property. Michael worked closely with us throughout the entire process—from early ideas and structural planning through to execution. He consistently provided insightful, practical advice that added real value. His ability to anticipate issues early not only prevented problems but also helped us save money by refining the plans to maximise our goals and avoid unnecessary costs. Michael’s broad knowledge and skill set were hugely beneficial on a project of this size and within a tight budget. He made the process far less stressful and, at times, genuinely enjoyable. He kept me informed and involved at every stage, which gave me a great deal of confidence in both the quality of the work and the decisions being made throughout. Michael helped us renovate every corner of our four-bedroom maisonette in West London—from bathrooms and structural opening-up works to a full kitchen renovation, hard landscaping, flooring, and carpentry. The list goes on. His wide skill set and depth of knowledge were truly impressive and exactly what we needed, particularly as we chose to stay closely involved in the renovation rather than hiring a larger construction and project management company. We genuinely don’t feel we could have made a better choice. It’s not always easy to find a builder who is reliable, honest, and trustworthy, so I feel very fortunate to have worked with Michael. I would recommend him without hesitation and will absolutely continue to work with him on future projects, big or small.

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.

Alex and the guys did a brilliant job from beginning till end. They were so helpful in getting a quote and advice on how to best proceed. I also got a clear upfront quote before work started. They did the job exactly as discussed and in the time expected, and it looks really nice. They're also really nice people, tidy and considerate and just no hassle at all. I'll definitely hire them again for any future work. It was only a days' work, and the whole job was finished in less than a week from when I posted the ad. I really can't think of anything negative to say at all.

I recently completed the building of an orangery extension (with skylight) to my semi-detached townhouse in NW London. The extension was to be used as a new kitchen while the existing kitchen converted to a living room. I awarded the contract of building the extension to Anthony and I was pleasantly impressed with the quality of work delivered. Anthony Project Managed the entire process from beginning to end and ensured that all my expectations were surpassed. His hands-on attitude to every detail of the work was quite reassuring. I am glad to say that Anthony and his team are very good professionals and they delivered the project on time and within budget, even going over and beyond the original scope of works in order to ensure that all my latter requests were addressed appropriately.

Restoration & Refurbishment- 4 Sep 2020
Octavian is a really great guy, very reliable, never disappoint, maintained good communication with us all the time. As a customer, obviously the most important part is great craftmanship, we have used other teams before and you can easily tell the difference between his work and the others. From things such as painting (you can tell they have paint and sand multiple times to provide such great finishing), tile installation (the gap between each tile is tiny, and they are very flat), Octavian’s team can get them all done. This job involves a full flat refurbishment, so the flat was completely stripped, knocked down a few walls, install new pipes / wire etc. During his work he has spotted many things that we have not noticed before. Unlike some other contractors who do not care, they will just finish what they were asked to do and leave. Octavian spotted it and recommend us the best solution for it, to provide the best outcome for the project. It is important to find someone who do care about the customer and the project. We will use him again for our future projects. Thanks. Tommy

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.
