Windows and doors are difficult to install. You have probably heard it from anyone that has ever tried it, and certainly from the experts that may come to your home and say a few colorful phrases as they try to make the door or window replacement fit into place. So, what makes the replacement piece so difficult to fit into the existing area, and what steps are taken to try and make one fit into the other? Here is a short version of the actions used to hang a vinyl window replacement.
The old saying about measuring twice and cutting once certainly applies when ordering windows. The measurements must be precise because even 1/2-inch can make a difference in how the window fits into the opening. Other critical dimensions include the opening squareness, the bottom level of the window hole, and the plumb of the frame gap. If the opening is not level and plumb, the window will jam when anyone attempts to slide it open.
Two people are required when hanging a window replacement. For the bottom sash unit, the stop moldings are removed, the bottom sash is inched out in one piece, the holding ropes are cut, and the heavy counterweights must be guarded so they don’t fall into the window. These steps are again repeated for the top sash unit. The area is cleaned, and the replacement is eased into place, one person holding the unit while the other checks for fit. If the fit is a good one, caulk is applied around the area between the new window and the home’s wall. The window is secured against the stop molding, and the level is checked, adjusted, and checked again. Shims are used to adjust the window’s level. The window is secured into place with screws, and the area is finished with a molding.
Professionals use the above steps to make sure your window replacement units are secure, slide easily, and will last for many years to come. It is no wonder you may have heard windows are difficult to hang – they are!
