A Window & Door Replacement Project in Apex
One Apex project shows why thoughtful product selection and experienced installation both matter. The homeowners contacted Kelly Window and Door after dealing with fogging between window panes, deteriorating exterior trim, and exterior doors that had become worn, poorly aligned, or uncomfortable. They had worked with Kelly previously and returned to our team when they were ready to address the windows and doors more comprehensively.
The project included made-to-order replacement windows along with several ProVia door solutions, including a sliding patio door, a steel front entry door with a sidelite, and another exterior steel entry door. When the existing hinged patio door was removed, our installers also discovered rotted wood at the bottom of the opening and addressed the damaged material before completing the replacement.
It is a good example of why replacement projects need to account for more than what can be seen from the outside before work begins. Careful evaluation, appropriate products, and an installation team prepared to address existing conditions all contribute to the finished result.
