Replace Your Windows


Over time, your Pennsylvania windows can lose their seal and start letting your heat and air conditioning escape. This can cause your home’s thermostat to fluctuate, which can lead to you spending more money to keep it at the right temperature. When you replace your home’s windows with durable and efficient ones from P.J. Fitzpatrick, you can save up to 40% on your energy bill. Our windows are expertly crafted and thoroughly tested to make sure that they keep your home warm in the winter and cool in the summer. Plus, they’re low maintenance, so you can enjoy their elegance and richness for years to come.

Environmentally Friendly

At P.J. Fitzpatrick, we’re proud to offer Pennsylvania windows that can help you lower your carbon footprint. With Infinity windows by Marvin, you can enjoy Ultrex windows that are glazed with Low E II insulating glass. These windows are 35% more energy efficient than double-pane glass and 64% more energy efficient than single-pane glass, so you can enjoy lower energy bills and become part of the “go green” movement.
