I was badly disappointed with the work, discussed this with Petru, sent him photos, he was still adamant he had done excellent work. I had to engage another contractor, who I had to pay not only to do the work, but to undo the poor outcome of Petru's work. I hired Petru based on his excellent feedback, and considered asking him to do more work in my home; I regret that decision, and will not hire contractors via websites like this any time again.

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.
