This company started out in the US as a sunroom manufacturer and has extended its technology to windows and doors. Their product is pricey but we are so impressed with the energy savings we have realized and the increased comfort and beauty of our home that we will recommend this company very highly. Service has generally been responsive, the installers were fabulous - quick, clean, and friendly, and the financing option is attractive, with a 1 year no-payment option. We did have to wait an additional 6 weeks for our doors due to problems with the US manufacturer but they were worth the wait. To their credit, the company contacted us numerous times with updates and apologies, and when the doors finally did arrive, they sent their workmen right away to complete the work before a previously planned business trip. Overall, this has been one of our best reno experiences.
