If you're thinking about replacing a window, you should know a few things about window installation before you get started.
First, a contractor should assess the windows in your home to determine the best treatment. Depending on the location of the windows, some changes may require alterations to the walls, which can increase the cost. Moreover, if you're replacing a large window, you may need additional help from someone else.
Professional installers should take exact measurements of the opening in order to properly install the window. Most replacement windows are custom made, so the measurement should be exact. In addition to ensuring that the windows fit perfectly into the space, it will also help to create a weather-tight seal. This will keep the elements out, which is important in an outdoor environment. Once this is completed, the installers should clean the area, and dispose of the old windows.
After a window is measured, the installer should use a 20-point checklist to ensure a proper installation. Once the measurements are made, a drop cloth will be used to keep the house clean. The installer will use quality-tested tools and materials to install your windows. Lastly, the contractor should use a metric tape measure to determine the width of the window's opening. Ensure that the measurement is accurate. If it's not, you can always hire someone else to do the work.
