Great service, very nice guys! Installed new windows for our house with Windowsville and could not be happier, so much warmer now with the heating season and looking forward to see how much less I am going to pay while cooling in the summer as well. Also gave me a discount! Keep up the excellent service!

Frequently Asked Quetions
While Low-E coating is not visible (for most of the Low-E grades), it provides year-round solar control and comfort in all types of weather. In hot weather it rejects the sun's heat and harmful UV rays. In cold weather, it reflects heat back into the room. Different levels of Low-E coating are available. Our consultants will be happy to explain available options in greater detail.
Argon is an inert, odourless, safe gas, which is denser than the air. It is used as an insulator between the panes of glass. As a result, windows provide reduced inter-pane convection and yield improved thermal insulation efficiency. Argon helps bring the temperature of the window closer to room temperature, while also offsetting water vapour to prevent condensation. Argon-filled windows provide better energy efficiency.
Caring about windows from Windowsville is easy: you can use mild cleaning solutions for the glass and a cloth with warm water for the frames. Due to the benefits of our quality vinyl construction you avoid a lot of other concerns typically associated with older windows.
With some prominent common features between them, bay and bow windows are sometimes mixed up. A bay window is comprised of 3 panels which are installed at an angle to protrude from the wall into the exterior space. The larger panel is installed in the middle. Bow windows are comprised of more than 3 panels with usually a more rounded appearance and may be wrapped around building corner for panoramic view.
We will send you a preparation reminder before the installation date. Typical actions to be taken prior to the installation are ensuring that someone will be present at the residence to allow Windowsville installers access your home, clearing the driveway where possible for the truck to park, moving furniture away from the windows and doors to be replaced, and removing any additional objects attached to or around your windows (blinds, shades, curtains). The security alarm sensors will need to be removed to be reinstalled by your monitoring provider.
Usually you do not need to keep the same type or style of windows. If there are any limitations due to size or location, our consultants will point them out and will be happy to walk you through the available alternatives. Generally choosing your new windows is a very exciting process as they are an important element of your home and can make a lot of difference to comfort.
