Cannot rate this company highly enough; they were brilliant. The quality of the work was great; they took pride in what they did. They came and quoted, and provided a clear statement of work on what we agreed. They completed the work quickly. Turned up when they said they would, and if they couldn't, they let me know. Really good communication. They were so polite, courteous, and just generally really nice people to have in your house.

Marius and his team are fantastic. They are highly proficient across all the building disciplines so don't need to sub contract out any of the work, This means that the project runs incredibly smoothly and at a very competitive budget. I have nothing but praise for their work ethic, communication and organisation. I would recommend them to anyone. No matter how big the job, from bathroom fitting to multi storey extension, you are guaranteed a great result.

There isn’t enough space on here to describe how happy I am and stress free Rob and his team made the process. I had a major extension to the rear and side of the home which meant I wasn't able to use the bottom area of my home at all. Rob and his team took care of everything and also provided so much extra help all the time any time and keeping up with the consistent service is truly unmatchable. I’m very happy with the work, the finishing and everything else. Choose Rob and his team and you can’t go wrong

Good work (probably) but terrible to deal with. Put a lot of moral pressure on me to pay in full before last bit finished. 'I'm not interested in your money, I'll come and do the last bit anyway' etc .Have not returned and not contactable. No guarantee for most of the work as just not providing one.
