Customer testimonials

02 Apr 2022

Charles and his team did a fantastic job on our loft bathroom/remodel. Everything was completed to such a high standard, they offered their advice throughout when it came to practical layout decisions and explaining how things were done. It was really reassuring to be kept informed of how things were going. I was always amazed at how much was done each day and felt fully at-ease with the house being in safe hands while I was at work. - Lauren

Having encountered problems with builders in the past, we approached this project cautiously. However, the referral we received about Cubit was justified and helped ease our concerns at the first meeting and continued to the project go-live. Any reservations quickly evaporated as Charles and team followed drawings and plans to the letter, also offering valuable suggestions when approached and proactively. The entire team is professional, and their standard of work is very high. When assessing the scope of the project and it’s delivery, we would say that Cubit has been an extremely valuable partner and wouldn’t hesitate in recommending them. - Danny & Claire

Charles and his team built us a huge back extension, which included an office, wet room and hydrotherapy pool room. During the job they were tidy, polite, hardworking and totally trustworthy. The job was completed to a very high standard, attention to detail is spot on. We are absolutely delighted with the work done. Couldn’t recommend them highly enough! I will be using their services again. - Antony Zenonos

There’s wasn’t the cheapest quote but Charles seemed far more competent than others who quoted, and the work included was more comprehensive! Charles and his team did an excellent job, and delivered exactly what was promised. They were professional throughout and kept us well informed at every stage of the process. All costs were laid out upfront, and there were no unexpected add-ons. I thoroughly recommend them. - KN
