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.
