The first step in window installation is determining the size of the opening. If the window is smaller than the size of the opening, it is important to make any necessary adjustments. When measuring the opening for a new window, take measurements of the height, width, and sides of the new window frame. The contractor will use the smallest measurements to make sure that the windows will fit properly. Then, use an Air Shim bag to nudge the jambs into place.

If the new window will be placed in a wall, you will need to make sure the opening is level and free of obstacles. Remove all clutter from the area. Move any furniture or coverings to four to six feet away from the window openings. Trim any shrubs or landscaping to provide enough clearance for the crews. The space between side jambs should be about two feet. A bow or bay window will require even more clearance. A drop cloth will help protect the surrounding area.

You should hire a certified installer, but check with the Better Business Bureau to determine what certifications the company holds. The American Architectural Manufacturers Association (AAMA) has a certified window installer program, which is a mandatory requirement for those who do business in Canada. You can also ask for references to verify the quality of an installation company.

When choosing a window installer, it's important to choose a company with experience in commercial buildings. These companies specialize in commercial window installation, which means they should know how to handle these types of installations. Additionally, they should understand the different types of installation. If you're replacing an existing window, the installer should be able to install the new one correctly to maximize energy efficiency. If the window installation team doesn't have experience installing windows for commercial buildings, they should not be hired.

During the preparation stage, the installer will need to take care not to cut into the weather barrier, which is a layer of special-coated material designed to keep water out of your walls. Once the window is installed, the window installer will drill holes and shims to ensure that it's installed properly. If the window doesn't fit, the window installation team should adjust the sill to make sure that it fits properly.

A quality window installation can make or break your new window. The best installation will provide you with a seamless and secure window installation. By following these guidelines, you'll have a window that fits perfectly and doesn't leak a drop of water. The proper installation will also prevent broken glass. This can be a difficult task for a homeowner. Luckily, there are professionals who can assist you with the process. If you don't have the time, you can hire an installer to do the job for you.
