Replacing a window can take anywhere from four to seven weeks after the windows have been ordered. Most businesses can install between ten and fifteen windows in a single day. The process begins with an initial evaluation, followed by the contractor taking measurements to ensure the manufacturer has the correct dimensions. After that, the windows are sorted for a custom fit and delivered to the contractor's warehouse.
Once the installation date is set, a highly qualified window installer can install up to fifteen windows per day. On average, it takes six to eight weeks from start to finish from the date the contract is signed. It's important to note that this timeline can vary depending on the size of the project and other factors. If you're looking for a more accurate estimate, it's best to contact a professional window installer for an assessment of your specific needs.
