Conversions - General- 23 Jul 2025
I recently had the pleasure of working with Teimo and his team on a full renovation of a probate house, and I couldn't be happier with the results. The entire house needed a complete overhaul, including two new bathrooms, a kitchen extension, new doors, skirting, walls, plumbing, electrics, as well as front garden paving, a brick wall, and back garden fencing. The quality of the work is outstanding. Teimo and his team take immense pride in everything they do, and it really shows in the final product. They are not only highly skilled but also incredibly polite and tidy, ensuring the worksite remained clean throughout. They worked hard, from 8:30 AM to 5:30 PM every day, and completed the project on time without any issues. What truly stands out about Teimo is his honesty and clear communication. He’s upfront about everything, and you can trust that the price you’re quoted is the price you’ll pay—there are no surprise cost increases along the way I highly recommend Teimo and his team

My advice is avoid. Poor communication Poor workmanship Poor quality finish Create 'issues' during build to make you pay more than quoted Left project incomplete We pursued through the Court and won the case, but of course he is unable to pay, so we are pursing further through the Court. He will respond to the review with some excuse, but there is absoultley no excuse for poor workmanship and quality. Happy to share pictures and videos on request.

Extensions- 4 Aug 2019
Very constructive input throughout the whole process. We were given a clear idea of timescales for every step of the build, what to expect and how they would minimise disruption to our household which was all done effectively as promised. For the beginning he made clear that the process would allow us to still have a family home running (almost) as normal for most of the build, which was really helpful with our young children! Baz would always answer any questions and welcomes feedback. He would be flexible and find ways to work around problems to ensure the design was achieved and did so beyond our expectations. The build was completed to schedule and to a high standard. He would work with you to make sure everything was done properly and around schedules you have with other services if you are using separate glazing or kitchen suppliers as we did. We’re very happy with choosing Smiley building services and would definitely use again. All his staff are friendly, polite and considerate. Friends and family who have seen the work on our house have already asked for Smileys details for their own build work due to the great finish.

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.

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- 16 Nov 2019
I was very lucky to find Cornel for my building work. His team were extremely hard working, efficient and respectful and the work was done very quickly and to a high standard. Most estimates for the build time were between 8 and 10 weeks - my work was fully complete in 6 weeks. Building control passed all stages of the work without any issues. He is equally proficient at the plumbing, electrics, flooring, tiling and decorating as the heavy building work, even restoring my garden so that it looked better than it did before the build. I am in a conservation area with close neighbours on all sides and Cornel minimised the disruption as much as possible and made efforts to keep everyone happy. His attitude to overcome problems and make sure that in the end you are a happy client drives his approach to the work. I had 10 builders quote for the job and Cornels quote was very competitive and the final costs were exactly as we had agreed. I had spoken to a number of his previous clients before going ahead and they were all very impressed with his work and had good experiences. It can be a difficult decision to choose a builder if you have no previous experience and given the potential for things to go wrong - but we made the right choice. I wouldn't hesitate in recommending Cornel and his team.

Gerti completely renovated both of our bathrooms, and the final results were absolutely amazing—exactly what we wanted. He was extremely flexible, offered valuable advice for other aspects of our home, and consistently went above and beyond. Having done a lot of work on our house, we can confidently say he is the best builder we’ve worked with. His pricing was very reasonable, and we will definitely use him for future projects.

Restoration & Refurbishment- 28 Dec 2015
I did quite a bit of research before choosing Battersea Builders. They didn’t come in with the cheapest quote but I never base my choice on price alone. And it wasn’t miles above the other quotes I got. Instead, I chose them because they ticked a lot of boxes including a) good independent reviews, b) a dedicated PM, c) qualifications, d) quick responses, e) a decent website etc. Overall, they did a fantastic job. The quality of the work and finish is really good. The PM, Tommy, was really helpful throughout and the team was very polite and conscientious. They were also on site every day as promised and didn’t play that old builders trick of getting the job and then going offsite to secure another job elsewhere (resulting in the deadline being missed). Was it perfect? No, but then not many projects are. I have a few minor comments including the fact there was a misunderstanding about the quality of bathroom cupboard I needed so the original quote was insufficient and costs had to be increased half way through the project. Despite this issue, Tommy did his best to keep the extra costs down. One other niggle was that I asked them to keep all the manuals and instructions for all the fittings but they threw them out. Not a big deal but quite annoying. Overall, it wasn’t cheap but I would use them again because the work was done to a high standard and the team were a pleasure to work with.
