Window Replacement and Repair

Did you know you could be losing 25%-35% of your home’s heat through your windows? If your windows are old, outdated, or just poorly made, they’re likely letting your heat or air conditioning out and letting drafts in. This means that not only is your HVAC system working harder to heat or cool your home, you’re also paying more in energy bills to have it do so.

At P.J. Fitzpatrick, we can help you choose replacement windows that not only look great in your home, but also help you save money and stay warm. With so many window manufacturers and materials to choose from, you may be wondering which is best for you. Our experts can help you decide.
