The amount of time it takes to replace old windows can vary depending on several factors, including the number of windows being replaced, the type and size of the windows, the installation method, and the experience level of the window installer.
On average, a single window replacement can take anywhere from 30 minutes to a few hours, depending on the complexity of the installation. Full-frame replacements, where the entire frame is removed and replaced, can take longer, typically a few hours per window.
For larger projects, such as replacing all the windows in a house, the time required can range from a few days to a few weeks, again depending on the factors mentioned above. The window installer should be able to provide an estimated timeline based on the specific project details.
It’s important to note that the installation time is just one part of the window replacement process. The entire window replacement process, including ordering the windows, preparing the installation area, and any necessary finishing work, can take several weeks or even months, depending on the scope of the project.
