  • "From planning through construction and finishing, this company has excellent staff and subcontractors; excavation, structural installers, etc. The quality of the finished sun room is excellent, and this is a comment made by everyone who has come to visit since."

    Rob and Sabrina S., Aurora, Ontario

  • "I am extremely particular and each day when I would come home to see what progress had transpired on my sunroom, Chester, my installation person, was patient and answered all my questions. His personal touches made my project unique and special to me. Every detail that I had on my wish list was expertly taken care of."

    Ann W., Unionville, Ontario

  • "The project was not a simple design and required the removal of a wall of the house, and construction of a basement below the existing basement, not to mention you had to work with our contractor and follow the building code, but you dealt with these issues professionally. The sunroom fits in beautifully with the rest of the house and it is everything we wanted and more."

    Mike W., Toronto, Ontario

  • "Not only do we use and enjoy the new sunroom your team installed, but it has also enhanced our property. It receives many favourable comments, not only from our friends and neighbors, but also from strangers who see it from the outside."

    Stanley P., Thornhill, Ontario

  • "My sunroom is completed now and looks lovely and feels great, but that is not the whole story. Peter, I value your thoughtful, informed, and educated sales approach. I never felt pushed or manipulated. It was a joy to work with you in throughout the process."

    Rick L., Etobicoke, Ontario

  • "It was a pleasure to have John and Brett (Installation Crew) install our solarium. The quality workmanship and attention to every detail is as important a component as the Wonder glass technology itself. It was truly a delightful experience to see real experts at work."

    Allan and Rena S., Bolton, Ontario

  • "I want to express to you our profound satisfaction with the job you have done for us. From the outset you were extremely courteous and knowledgeable. The planning was carried out in a very careful manner. You started and finished on schedule and there were no hidden extra costs. The sunroom has already become our favourite place in our home."

    V. Rachlis., Toronto, Ontario

  • "We are delighted with our new Four Seasons sunroom. We were grateful for Rob’s personal commitment to ensure the best possible installation of our sunroom. His extensive knowledge of general construction was invaluable. Rob continued to be responsive and support in answering questions after complete of our sunroom."
