Adrian and team did a fantastic job on my back garden from it looking like a building site initially! And they did it in less than 1 and a half days, truly amazing! As well as this, the team also fitted in additions to what they thought would look and be better for me overall. Great work, would highly recommend! Am also going to ask for my front garden to be done also.

Edilson was very efficient, communicative, and clean during the job. He explained everything that he was doing, and made suggestions about how to make the most of the space we were using. He even did a few extra odd jobs for me at the last minute. I've now shared his details with all of my family, and they will be using him in the future. I definitely recommend!

What a nightmare! You could be forgiven for thinking removal and refitting of toilet mean they will refit back with no leaks. Not only did they leave me with a leaking bathroom for a week with damage to my walls and ceiling, they then wanted to charge me £150 labour to fix by replacing a valve!! I wish this review gave me the option to add pictures so you can see the extent of the damage and bad job they did. Small positive was that the tiling itself was mostly ok but will NOT use again!
