Thank you Ionut and the team, im so happy to have a space where I can be proud of! I needed the existing paving slabs removed and to put in place decking, artifical grass, and planters put in. They provided the materials and kept me informed in the process. They are hardworking and I saw a huge difference for every day they came. Thank you once again for taking on this project, and I'm so happy this has all been done before summer has started! Would hire again!

The day before he was due to start, he cancelled with a lame excuse. Totally left us looking very stupid and the client very upset. Do yourself a favour and look elsewhere.

More broken slabs has been replaced by him 3 times in 6 months. He has refused to respond to my calls. He texted back calling me. STUPID when I texted him to say I will report him to RatedPeople and the authorities. More slabs broke 2 days ago. Sent him the picture. He simply texted back: MOVED TO DEVON NO LONGER WORKING.
