We hired Cani Building Services to replace the front stairs and pathway of our Victorian home with granite pavers in the spring of 2025. When evaluating the builders it was important to us that we found somebody who was professional, reliable, and detail-oriented. Durim offered a competitive quote and promptly started work. ?He completed our job to a high level of quality within a week’s time, and we are very pleased with the outcome. We would absolutely recommend his services to others!

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

We used Kingz for clearance of a very overgrown garden and new fencing. They did exactly what they said they would do in their quote. They worked hard, left the garden tidy, and took away all the waste. They were very pleasant and Emma, in particular, gave good advice regarding ongoing after care of the garden. We were very happy with the results and would definitely recommend this family team!

Harry and Mark were absolutely brilliant. Harry's communication was excellent and he went above and beyond on my bathroom and full flat renovation. He made helpful suggestions, managed parts of the project, sourced a new boiler at a great price, and brought in a fantastic team. I trusted him fully, even giving him a spare key. I felt genuinely prioritised and supported throughout. Would highly recommend.
