At The Window and Door Specialist, we understand that a quality installation is just as important as a quality window. That’s why we employ a team of professional installers who use the latest techniques and materials to ensure a perfect fit every time.
We offer two installation methods to suit your needs and budget: brick to brick and retrofit.
Brick to brick involves removing all components of the existing window for a larger glass area and consistent look, while retrofit is a more cost-effective option that preserves the interior moldings.
In other words, a brick to brick installation involves removing all components of the existing window (sash, frame, interior trims, flashing, brickmould, etc). This method of installation ensures the new window is plumb and level and adequately insulated. Because all components are removed, the opening will be bigger allowing for a larger glass area and a cleaner more consistent look.
But, retrofit method of installation is typically utilized when if you wish to preserve the interior mouldings or when cost is a concern. The existing sashes are removed, and the new window is installed into the old frame. The exterior frame is clad in aluminum.
