Extensions- 18 Oct 2017
I asked Prohaus to undertake a ground floor side return and rear extension as part of the refurbishment of my flat in Putney. I have used many builders before on development projects but was especially impressed with Naz and his team on this build. It was the first time I used them and won’t be the last. Naz was great to work with, the whole build went smoothly and he always had a positive attitude and solution to any unexpected issue. The build came in on time and budget which was very impressive in itself. All in all I would highly recommend him.

Bathroom Fitting- 15 Oct 2024
Actually, I prefer to call him as Super Mario instead of Loui :) Initially I agreed to work with him just for our bathroom renovation project but he fixed almost everything later on. Pipe installation, plastering, painting, and installation of furnitures are just some points of this work. He made an amazing job while renovating our bathroom, I still could not believe it is ours. I just observed he was very disciplined and working vey clean. He came early 8 AM and left around 5 PM without any delay and more importantly left my property enormously clean (I wish you see my wife’s happiness), almost for a week. He then replaced my garage roof which was leaking after every rain. Fixed my rain gutters and drains. Well, he then fixed all my internal doors and garage doors which were not aligning properly. I am so happy as a customer and I am really happy with the quality of work. Thanks again Loui.

The london Loft and Kitchen Company
Rating: 4.5 out of 5
Extension Builder in Wallington
We are a southwest London Based loft and kitchen extension specialist. Our working area is very small with 90% of our jobs in Wandsworth and any work outside this area is never more than a mile or two away. With over 15 years experience in this area we know inside and out how these properties were built so when it comes to structural alterations you couldn't be in safer hands.

Extensions- 16 May 2017
Initially apprehensive about using mybuilder, we found David easy going, clear and concise from the offset. The work carried out was to a high standard and any changes or questions that arose he was all to happy to answer. We found him to be pro-active in his approach, open and honest with how much items cost and sensible when agreeing monthly valuations. Both of us work in the construction industry and it is enjoyable and a breath of fresh air when you get to work with people as straight forward a David. We hope to do work with him again and would be happy to talk with anyone who is considering taking him on for additional work. Many thanks, Rob and Brom

Ivan and his team completed a full loft conversion at our terraced house, and we couldn’t recommend them more highly. They did a fantastic job from start to finish and were a pleasure to work with. Communication and project management throughout the project was excellent, and their commitment really showed. Nothing was ever too much trouble to ask. The project was completed within the estimated timeframe, which was especially appreciated as it finished just before Christmas. The team was very considerate while working in our home, and we stayed in the house for the entire duration of the project with minimal disruption. In addition to the loft conversion, they also replaced all our doors with fire doors and installed new flooring throughout the house, all to a very high standard. We’re absolutely delighted with the results and would highly recommend Ivan and his team to anyone considering similar work.

Gavin built me an outhouse at the bottom of the garden. The work was tidy and efficient and the result just what we agreed. This involved brickwork, carpentry and electrics, and all was done to a good standard and in a reasonable timeframe, even despite the snow! I would recommend Gavin to do this sort of work and would use him again if needed.

We needed a rear extension built with an internal courtyard. From day one when we first contacted Mert to get a quote he was professional and easy to talk to. His quote was good value for money. During the job he and his team were approachable, careful with our property and always easy to talk to and answer questions we had. The work Mert did was fantastic and our neighbours have already gone on to use him. We will get him back again for more work and highly recommend him.

Extensions- 22 Dec 2022
Imran is a contractor who is personable and is trying hard, but at the end relies on different teams of builders to carry out the work. His knowledge of building work appears at time limited. In our case, this has often led to poor communication/hand-over, extensive delays and often poor (if not careless) craftsmanship. Very stressful. We now have builders (family business) finalising our project.

My house was old and its condition was poor. Much were needed to be fix. The original kitchen layout were also inconvenience to my wife. I need to have all these changed under limited time. This builders have a team of specialists on almost every aspect. They gave me variety on the layout design and choose of materials. This saved me money, time and tons of trouble to find difference contractors. The after service and their respond time are very good too. I hope by sharing my happy experience can save your money and trouble to find a good contractor.

Bathroom Fitting- 14 Mar 2025
My previous bathroom fitters did a very bad job with the bathroom and cloakroom toilet and left it unfinished. I am so glad I went with JM Building service as Joe and Martin completely transformed both rooms. They rectified the previous fitters errors and completed the rooms. Joe didn’t just rush through the job to get it done quickly—he took his time, ensuring every detail was finished to a high standard. He worked meticulously, making adjustments until everything looked exactly as it should, rather than settling for ‘good enough.’ His dedication to quality and precision was evident throughout, and the end result speaks for itself. As well as being very good at what they do, they are friendly, reliable, trustworthy and hardworking. I have already booked them in for another job and requested a quote for another. I highly recommend JM Building services for their professionalism and craftsmanship.
