Penn Windows & Doors I'm Erin Duffield, 2nd generation owner of Penn Windows & Doors. Penn Windows & Doors has been a local institution since 1948.

I've been working at Penn Windows since 2000, purchasing the company from my father (Rick Hauler) in 2020 and bringing on my son, Michael Duffield to help keep the family business going. Their showroom is located at 1518 Union Boulevard in Allentown, PA. They offer free in-home consultations for their custom vinyl windows, steel and fiberglass doors, storm doors, and patio doors. Call the office at 610-433-4196 to speak with Erin.

Some homes naturally bring people together.

Sliding windows open with a smooth horizontal glide, making them a practical choice for wider openings and living spaces that connect seamlessly with the backyard.

From family cookouts in Macungie to evenings spent entertaining near Whitehall, the right window can make indoor and outdoor living feel even more connected.

Some of the most important parts of a window are the ones you rarely notice.

Window seals play a vital role in helping keep conditioned air where it belongs, improving insulation and supporting the long-term performance of your windows. When seals perform properly, your home stays more comfortable through every Pennsylvania season.

For homeowners in Allentown, Bethlehem, Easton, and throughout the Lehigh Valley, paying attention to these small details can make a meaningful difference over the years.

At Penn Windows & Doors, we believe lasting quality comes from understanding every part of the window, not just the glass you see every day.

The quality of a window or door depends on more than the product itself.

It's the careful details behind the installation that help it perform as intended for years to come. Accurate measurements, proper leveling, dependable sealing, meticulous finishing, and leaving a home as tidy as we found it are all part of doing the work properly.

For homeowners in Allentown, Bethlehem, Emmaus, and throughout the Lehigh Valley, those details may not always be visible, but they're often what make the greatest difference over time.

At Penn Windows & Doors, we've long believed that true craftsmanship is measured not only by what you see, but by the care taken in every step of the installation.

A front door should do more than welcome guests.
It should suit the home behind it.

Fiberglass and steel entry doors each offer distinct advantages. One is valued for its versatility, insulation, and low maintenance. The other has long been appreciated for its strength, security, and dependable performance. The right choice depends on your home, your priorities, and the character you wish to preserve.

For homeowners in Allentown, Bethlehem, Emmaus, and throughout the Lehigh Valley, selecting a new entry door is an opportunity to enhance both beauty and everyday comfort.

At Penn Windows & Doors, we're proud to help families choose entry doors that complement their homes for many years to come.

A comfortable home isn't only about staying warm in winter or cool in summer.

Modern replacement windows can also help reduce the amount of outdoor noise that makes its way inside, creating a quieter space to relax, work, or spend time with family.

For homeowners near Cedar Crest Boulevard, Whitehall, and other active parts of the Lehigh Valley, that added comfort can make a noticeable difference.

Not all condensation tells the same story.

Moisture on the room side of your window can happen when indoor humidity is high. Moisture trapped between the panes often points to a failed insulating seal.

It's one of the clearest signs homeowners throughout Macungie, Easton, and across the Lehigh Valley should have their windows evaluated.

Some window styles have remained popular for generations, and for good reason.

Casement windows are hinged at the side and open fully outward, allowing fresh air to move naturally through the home. When closed, their design forms a secure seal that helps improve comfort and energy efficiency in every season.

They're a fitting choice for many homes throughout Allentown, Bethlehem, and neighborhoods near Cedar Crest Boulevard, where homeowners appreciate craftsmanship that's as practical as it is enduring.

At Penn Windows & Doors, we're proud to help families across the Lehigh Valley choose windows that will serve their homes well for years to come.
