Dr. Glass is the metro area’s premier window-washing company offering award-winning service for more than 30 years.  Residential specialists, we are rated A+ by the Better Business Bureau and have won quality service awards year after year.
The Wall Street Journal
describes our service as impeccable. We've also been featured in the Washington Post, USA Today and on CNN & NBC News 4.
(Please see In the News)

Working together year to year, we become a part of your maintenance team! Rather than getting any old crew of workers (bringing water through the house, moving furniture, taking apart windows, walking through flower beds) we’ve kept our business small. Our customers work directly with one of our owners. You get to know us; we get to know you.

Please click on the different locales to meet us.

Our commitment is to be the best small service company you've ever hired!
