Durability and Efficiency


At our home improvement company, windows are just one of our many specialties. Whether your windows need replacing or you just want to update the look of your home, P.J. Fitzpatrick can help. We offer high-quality Delaware windows in a variety of shapes, sizes, styles, colors, and materials, so we can help you create the perfect look for your home.


Windows from P.J. Fitzpatrick are built from the best materials in the industry, so you can be sure that yours will last for years to come. Our vinyl windows are made from maintenance-free New Generation uiPVC that will never need painting or staining. We also carry fiberglass windows that are made from Ultrex material. This material is eight times stronger than regular vinyl and won’t warp or fade.


When it comes to efficiency, our Delaware windows can stand up to the harshest weather elements. They can also help you save on your energy bills. Because our windows are made from durable material, they’ll create a long-lasting seal that will help keep your home cool in the summer and warm in the winter. Plus, if you’re looking to go green, we carry insulating window glass that is 35% more energy efficient than double-pane glass and 64% more energy efficient than single-pane glass.
