Purchased 1 window and 3 doors. Salesman was friendly and gave written quote. Installers were very professional and careful. Window seems fine. The doors were Cobra Doors 2000 and also have Novatech stickers. They are not suited to the Winnipeg climate and are very poorly constructed. The weather stripping is very poor and these doors are worse than what I replaced. Window on one door leaks causing condensation and moisture on the outside. All weather stripping on all three doors leaks causing ice to form on the perimeter of the doors. Explanation from Northshield was that the humidity in the house is too high. It is between 35 and 40 that is actually on the low side for a healthy environment. Dehumidifiers cannot even be set below 35. Obviously I am very disappointed and frustrated. The doors were a big mistake.
