Nicolae was great to work with, very accommodating, quick and unphased by bad weather. Did an excellent job with the blockwork at a good price and a good job with the plastering, which was little bit more expensive, but worth the assurance of having the same person do both jobs. Would recommend for similar, quick turnaround jobs.

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.

I was very satisfied with the results of VFurb's external renovation and decoration work, which took 3 weeks in total, extended due to rain. Dragos worked six days a week to keep me informed of progress, answered all my questions, and identified practical solutions to unforeseen problems, supported by detailed costings . He was always present to supervise his team of 2-4 workers, and personally completed the most complex roofing, piping and guttering jobs himself to a high standard.
