Extensions- 25 Apr 2025
we recently had the pleasure of working with Leon building contractors limited, and i cant recommend them highly enough! They carried out a single story rear extension, an internal garage conversion and porch to the front of the house. On top of that they installed our new kitchen and toilet suite downstairs all finished to a high standard. From start to finish Vic and his team were amazing nothing was too much trouble and were always happy to do anything without a fuss. Their attention to detail was first class. It wasn't only us who was impressed but our neighbors commented how friendly, respectful and hard working they all were and have already asked for his contact details. Vic trade contacts also helped us with windows/bi-folds and quartz worktops all high quality at much cheaper prices i could find myself! Thanks again to Vic and the team for doing such a brilliant job, we have no hesitation to use again in the future!

Extensions- 16 Sep 2025
Steve and his crew did an amazing job turning my fag-packet designs and downloaded images into a proper, wonderful sound proof garden building, concrete external & rockwool cavity He’s a an old-school builder who does things the right way. His approach and mentality are always “how are we going to do this” rather than “I can’t do this,” I picked Steve on price and previous work. He came in middle price wise and was fair, it’s safe to say it was the right choice. He was left to his own devices, worked through all sorts of weather, and although the job took a little longer than expected because of that, he stuck firmly to his original quote. Although steve didn't know at the time, the garden room was my test for both quality, work ethic and trust, and Steve passed with flying colours. On the back of this, I’ve now commissioned him to build me a two-storey extension. I think I’ll buy him his own coffee machine for that project though! ;-) Thank you, Steve
