They worked with us from the beginning to select materials, while keeping our budget in mind. During the renovation, their team was clean and professional. We are very happy with their work.”

  • “Rahul is the best contractor I have ever worked with in Toronto. He's sharp, on time and communicates well and his prices are fair! If anything comes up, I will be asking Rahul and his team at One Oak... Outstanding workmanship and integrity to boot!”

    - Chris, Toronto
  • “I have been looking to renovate our unfinished basement for a while now. I am very particular when it comes to who I hire, but when it came to choosing One Oak there was no competition. Rahul's speedy and excellent customer service was very impressive, but not as impressive as the actual work done! We went from having a unfinished basement to an amazing space with hardwood floors, crown moulding, and beautifully painted walls. Job well done One Oak!”

    - Mary, Whitby
  • “I'm very happy and pleased with the home renovations that was managed by Rahul on behalf of One Oak. Our house needed some major renovations - wiring, new flooring, the removal of a couple walls. He was great to deal with in terms of pricing and was happy to explore various ways to help reduce the cost of the project without any sacrifices in quality. Rahul handled the project very professionally and dealt with a number of issues - including fixes for venting, flooring and wiring with ease. We are very happy with the result of the renovations as well as the cost. I'd be more than happy to recommend One Oak in the future.”
