What Our Clients Say

  • “Just a quick note to tell you how much we are enjoying the construction phase of our sunroom. Allan and Rolly are doing a superb job, the quality is evident at every step. Curtis, we need your assistance with replacement of the 2 wings, so that we can minimize the inconvenience to all parties. Thank you and best wishes to the crew in Cambridge.”

    The Drynans

  • “Scott and I would like to extend our heartfelt thanks, we love our new sunroom! From start to finish everyone has been so professional and conscientious. We would like to have either breakfast or lunch sent to your office as our way of saying thank you.”


  • “I’m writing this letter to thank Complete Home Construction and their workers for all their hard work. Over the period of the last 3 weeks, it’s been nice to have Allan, Ernie, Sean, Chad and Don at our house. The men were very professional and kept the work area clean and tidy. We are happy with the room, and look forward to using our space in the up-coming months. Again, thank you so much.”

    John Fage

  • “Thanks Curtis, our sunroom looks GREAT! Kim and Mal, thank you so much for your ongoing support, direction and assistance through this sometimes difficult journey in making my dream come true. The room is everything I could have hoped for and even more. Please also pass on my appreciation and thanks to Brad, John, your electrician, and everyone that was involved.”
