Maryland, DC, and Virginia’s Favorite Window Washing Company for 40+ Years!
Dr. Glass Founder Philip Bregstone.
Dr. Glass Window Washing is a family-run window washing company offering residential window cleaning services, pressure washing services, and gutter cleaning. Founded in Potomac, MD in 1978, Dr. Glass has been serving Bethesda, Montgomery County, DC, Virginia, and beyond for over 40 years—one squeegee and one window at a time.
ABOUT OUR CUSTOMERS
First and foremost, Dr. Glass exists to service the needs of our neighbors. Our customers—whether in Potomac, Bethesda, or elsewhere in the DMV—know how important it is to regularly maintain their homes. While regular window cleaning certainly makes homes more beautiful, it’s also an important step in home maintenance—especially in our region, where pollen, snow, rain, and high winds can wreak havoc throughout the year.
While our clients want to take proper care of their homes, they may not have the time, equipment, or experience to perfectly and safely clean all their windows. Fortunately for us, they rely on small, independently-owned family businesses like ours when it comes to annual home maintenance. Our customers appreciate the small business touches we’re known for—our master schedulers JC and Molly will always give you an annual call to remind you it’s time to schedule your next cleaning, and we try our best to send out the same crew each year. That way, you get to know us—and we get to know your windows! Because many of our clients have old, historic homes with fragile building materials and delicate home details, we’ve worked hard to become the leading window washing company when it comes to those difficult and complex window washing jobs.
Dr. Glass’s business has changed a bit over the 40+ years we’ve been providing residential window cleaning services. Our team has gotten bigger, our knowledge more expansive, and our tools more advanced. Overall, we’re pretty much the same—and our customers are, too. Many of our clients have been working with us for decades!

ABOUT THE COMPANY
Dr. Glass Window Washing began as a seasonal endeavor helping our founder, Philip Bregstone, cover the cost of tuition as a music student at Syracuse University. He noticed that his neighbors were in need of a window cleaner and so he began offering window cleaning services in Potomac, MD. Over the last four decades, we’ve expanded our team, our service areas, and our network of happy customers to become the preferred window washing company in Maryland, DC, and Virginia. Today, we offer the region’s best residential window cleaning services, pressure washing services, and gutter cleaning.
In addition to providing exemplary window washing and gutter cleaning, our biggest priority is building long lasting relationships with our customers. Customers describe us as professional, thorough, and efficient. With decades of knowledge and professional training, our residential window cleaners are experts in cleaning and caring for all window types and materials.

ABOUT OUR FOUNDER
Philip set up his business to fit with his family-oriented lifestyle, giving him ample time to spend at home with his wife, Roberta, and their two sons, Jonah and Julian, and to pursue his love of music.
He also encouraged the whole Dr. Glass team to do the same. Relationships with customers and employees were always a high priority to him:

"I realized this was all about service, and that 'real service,' the kind that stands out, is about interactions and relationships. With my customers, I share about who I am, and they reciprocate, opening up to me. Service is about becoming a person in someone's life. It's not a uniform or a van, it's the person. For my clients, it's the experience of having a Dr. Glass person in their house. I talk with my clients, let them know the things I care about, who I am, and really listen to them. I get to know them, their children, even their pets.”
— Philip Bregstone, founder of Dr. Glass Window Washing
Our window cleaners were personally trained by Philip to maintain the high standard of window washing services for which Dr. Glass is known. We try to send the same window washers year after year so customers will get to know the window washer that comes to their house personally.
Starting in 2000, Dr. Glass expanded beyond Montgomery County and started franchises in Northern Virginia and Annapolis, all in the mold of the original Dr. Glass Window Washing. These Franchisees still work closely with Dr. Glass headquarters in Maryland to maintain quality and consistency throughout the area.
In 2013, Philip was diagnosed with terminal cancer. This was a very difficult year for all of us at Dr. Glass. Since his passing during the summer of 2014, Roberta Bregstone, his wife, has taken over as the president of the company. The staff here at Dr. Glass has rallied to support her. Philip’s two sons, Jonah and Julian, continue to wash windows in his place—reaffirming our promise of quality service...
