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.
