I had the pleasure to discuss the works needed for a full refurb with John. He was very prepared, technical and knowledgable. Despite not being able to work together due to my location (too far from where RPC operates), John still kindly offered to give me a very accurate quote of the costs. This tells you a lot about how much RPC cares about their clients, but most importantly people. I’d definitely recommend RPC!

Raynes Park Construction did some work to help sort out some damp issues in my Edwardian house which involved putting in a new concrete foundation. Jon project managed the work and was available and responsive throughout to help resolve any issues. The company definitely make the effort to provide good service and value having a good relationship with their clients. I would use them again for other work!

Jon, Charlie, and the Raynes Park Construction team did a fantastic job completely refurbishing our one-bed ground floor flat in Raynes Park. The job involved completely stripping everything back to the bare brickwork, re-plastering the walls, new flooring throughout, new kitchen and bathroom. Finished product was like a high-end new built flat. The build was in 2018, and it still looks like new. We liked Jon and Charlie, from the start, and struck up a good relationship. What we particularly appreciated was the clear communication and pragmatic advice. My mother now lives in there, and is very pleased with it all - no greater accolade than that!

Great team, gave me lots of inspiration about what could be achieved, and then it was carried out even better. Never felt talked down to, and very tidy work. Highly recommended.

We are generally happy with Jon and his team for the our kitchen work. They are very responsive in communication and update of the project progress. When there were problems encountered even after the project completion, the team was eager to sort it out asap, they value highly on customer satisfaction.

Jon, Charlie and their team built our loft extension during 2022, and we couldn’t be happier with the service they provided. They were incredibly helpful during the planning of the project, kept everything within budget and even helped source some of my wilder ideas such as a giant custom built window. I was very pleased with the efficient service we received and having now seen the quality of the work, we will be looking to have them back to complete a rear extension in the near future.

We had a very positive experience with Jon and Charlie who were professional, quick to respond and provided a comprehensive and competitive quote. We had a hard time deciding and we went with a different firm in the end - but we enjoyed all of our interactions and appreciated the honest and straight forward approach.

Raynes Park Construction completed a rear extension at our Wimbledon house in 2021. Jon, Charlie and the team were very professional, worked exceptionally fast and delivered on all levels. We have been impressed with their response times and after care and wouldn't hesitate in recommending them. They were at all times honest and clear which made working with them very easy. They were very flexible when providing us with a quote for the work and it was great to work with such a local business. We are very happy with our new kitchen and dining space!

Whilst we didn’t proceed with our project due to external factors- we found Raynes Construction great to deal with. Charlie was very knowledgeable , personable and pulled together a very impressive quote with good detail. Wouldn’t hesitate to contact again.

Kerry Champkin, London
I found Raynes Construction to be conscientious diligent builders who stand out from the rest, they completed my loft extension within a 5 week time frame from start to finish, would use again & fully recommend them!
Jason Raul, London
RPC worked brilliantly for us. They came in and re-laid the beams in the floor of our loft conversion after the original builders hadn’t done the job correctly. They were timely, courteous and very tidy, also providing a good value for money quote. I’d recommend using them for any type of building project and we would definitely use them again.
