RCB Design & Build Contractors

Vasi and co did a great job removing the two old student showers and joining them together to make a single bathroom in our house. The work was done to a high standard, but what stood out was the communication. They gave an update of the work performed at the end of each day and we're very responsive to message. This was appreciated as it made me a lot less anxious about the work being done.

Bathroom removal and fitting

" I had a lot of problems with my conservatory, I.e cracked walls and dropped floor. I contacted RCB Design & Build, could not have chosen a better company. They were so helpful, explaining and outlining the reasons for my problem. They completely rebuilt from the base upwards, very hardworking, friendly and professional. Anca was on hand to oversee the progress of work and answer any questions I may have had. I can thoroughly and truly recommend this company for any kind of building work. "

Conservatory rebuild

From start to finish, we couldn’t be happier with our experience. The team is incredibly thorough—every detail of the quote was clearly explained, giving us full confidence there’d be no surprise costs. The workmanship is excellent, and the quality of the finish shows how much they care. Anca (our project manager and co-owner along with her husband) regularly check in to ensure everything runs smoothly. Even with a toddler, the mess was minimal! We’re already planning to have them do the rest of the house!

Exceptional quality, transparency, and care throughout

RCB continues to impress with their professionalism, quality and promptness. Got them to do the planning application including the architect drawings after a disappointing experience with another architect. RCB turned out the drawing in no time and got everything right first time. They are all set to submit the planning application in less than a week. Pleased that I chose them. I am sure they will carry this superb work onto the rear extension as well.

Planning Application Submission in quick time and of top quality

Vasi was extremely helpful on the phone and although doesn't exactly do the types of jobs we were looking for was extremely friendly, help and offered some really useful advice of where to try and find the right type of handyman. Thank you

Very helpful and friendly

We have decided not to go ahead with our project but communication with Vasi and his team was excellent and highly professional. I would certainly consider hiring them for a future project.

Great communication
