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

AVOID Adil is a smooth talker who hasn't got a clue about work in the industry. Employed to refurbish a full house. A SUMMARY of issues follows. 1 - Plastering done is uneven. 2 - Did not allow plaster to dry before painting walls so already peeling off. 3 - Found number of areas where holes had been left, and had these not been pointed out would have been left. 4 - Wood not sanded before painting, incl. new skirting boards. 5 - Threats when I refused to pay!

The guys were absolutely brilliant. They came round and within 20 minutes they knew what was wrong. They had a new boiler ordered and picked up that night and came back first thing the next day to fix it. Honest, friendly and had my new boiler fitted within a few hours. They found solutions to tricky issues they found due to the build of my flat. They went above & beyond.

Stanley & his team originally came on board to build us a new rear extension which would house our kitchen as well as fit a new bathroom but as the project developed it ended up being near enough an entire house renovation and we're thrilled with the results. We still have work we would like to do to the outside of the house as well as a loft conversion and when we have enough money to take on those projects, we would definitely re-hire Stanley and his team. Highly recommend Stanley & his team.
