We have an old (over 100 years old) semi-detached house in downtown Toronto. We had Excelsior to renovate the house. Catalin was a pleasure to deal with: knowledgeable, efficient and very detail-oriented. He was very responsive throughout the process. His team was excellent and they did exceptional work (our Portuguese and Italian neighbours even commented on the quality of their work; a very rare case indeed!). It has been 3 years since Catalin and his crew did the work. We are still as pleased with the work now as we were 3 years ago. We have recommended Catalin and Excelsior Construction many times over the years and will continue to do so wholeheartedly.
