If they're not cleaned every few days, your windows will turn black and begin emitting a high-pitched scream that makes dogs pregnant.

Choose from services in the DC area or in Montgomery County, which includes the Rockville and Potomac, Maryland areas.

Run by a migratory manager who road-trips to DC from his Colorado farm every spring, Dr. Glass Window Washing scrubs scum from panes with persnickety precision. Its business model, featured in such publications as USA Today and Kiplinger's Personal Finance magazine, keeps the company small so customers work directly with owners when they call to set up an appointment.

Before cleaning, pane polishers will slip off shoes to keep carpets spotless, place towels underneath buckets to sop up any spillage, and leave home interiors as pristine as a spit-shined mountain stream. Besides wiping down clear double hung windows inside and out ($10 each), dedicated de-dusters will navigate the treacherous straits between storm windows ($10 extra for each), the tight twists and turns of small colonial panes ($4 extra for each), and the crevasses of crank-out casement windows ($6 each).


Philip Bregstone, Dr. Glass Window Washing's founder, has been featured prominently in the press for his business model. Google Mappers give the Chevy Chase services an average of 4.5 stars and Potomac services a perfect five-star average.
