Derek has done three small fixes at my 77-year-old house. He's super professional, personable and efficient and he takes time to listen, explain what he's doing, and even tidy up the work area afterwards. He's outstanding and I'd reach out to him for any project big or small!
Have worked with Derek on an old house renovation for nearly two years. He has been one of the few professional tradesmen I have dealt with. He is there when he says tidy and conscientious about his work.
Derek is highly professional, extremely well-organized, and very fast. He has extensive experience in both residential and commercial work. I am an architect with over 40 years of experience, and I recommend him highly.
Prompt, professional, honest! Derek and his partner were incredibly helpful and thoughtful with the fixes I needed around my new house. They brainstormed things with me and were helpful! They quickly fixed the things that needed doing and sent over quotes quickly for future projects. I have had many contractors since buying this new house and Derek was exemplary. I would highly recommend his services and I will be reaching out to him for future projects!
