AVOID ! At all cost, honestly getting flooring done is so expensive and this company came ruined my new purchase herringbone flooring by laying it completely wrong! They don’t know what they are doing and have no skill. They are messy dust everywhere my walls sofa cushions, curtains everything is a mess. I stopped them and told them not to come back after paying an initial £600 wish I never paid anything now going to open a dispute. Awful is me being nice avoid these people!

Fired him for appalling work, no-shows and delays; see his other bad reviews. He's a middle man; does not do any work; got others to do it like a plumber, then a tiler the next day; slow work made worse when someone messed up or did not show up. Ali only shows to deliver materials or check work. Quick to reply when wanting the job. Slow/no response once job starts thinking you wont cancel. Materials I paid not returned; take every receipt and check you keep/use every item as he will even for wipes/tape
