Family owned. Neighborhood trusted. Serving the Philadelphia area since 1963.
Built on Experience
Gallagher Bros. has spent decades helping homeowners improve their homes with quality products, honest service, and professional installation. What started as a local family business has grown through generations, while still keeping the same personal approach that built our reputation in the first place.
For over sixty years, we have served thousands of customers throughout Philadelphia and the surrounding suburbs with windows, doors, glass blocks, garage doors, awnings, siding, and more. We understand the homes, neighborhoods, and practical needs of our customers because this is the community we have worked in for generations.
A Local Name People Know
A big part of our business has always come from referrals, repeat customers, and word-of-mouth. We believe that says a lot. Homeowners continue to call Gallagher Bros. because they know they will be treated fairly, listened to, and guided toward products that make sense for their home and budget.
Two Convenient Locations
Our original Philadelphia location has long served families throughout the city and nearby counties. As the second generation expanded the business, we opened our Hatboro showroom to better serve customers in Bucks and Montgomery County communities as well.
What Matters to Us
We believe good work still matters. That means showing up, measuring carefully, installing correctly, and standing behind what we sell. Whether you need one replacement window or help choosing doors, glass blocks, or an awning project, our goal is the same: make the process straightforward and do the job right.
Thank You for Visiting
We appreciate every customer who gives us the opportunity to work on their home. If you have questions or want to schedule a free in-home estimate, we would be happy to help.
