"Excellent, careful work, always on time and economical." say Anet Tarpoff and Pat Talbert, realtors, Oakland.  We clean windows for all their listings.
 
"We've been doing business with A-1 Window Cleaning since the Oakland Hills fire.  We are always delighted with  the work and know we can rely on you every time," says Mrs Sheila Malcolm, resident in the Oakland Hills.
 
Many of our clients call us back year after year, including Ferrari of San Francisco in Mill Valley.  We safely work in the showroom around multi hundred thousand dollar cars.
 
Last fall we cleaned all the inside windows at the vast Oakland Arena where the Warriors basketball team plays.  We shall be doing the outside in the spring.
 
We count on dozens of real estate agents among our clients including most of Berkeley Hills Realty agents, notably owner Nancy Mueller.  We have also done post construction clean-up on several homes for Robert Mueller, Nancy's husband.
 
Other agencies include Prudential, Red Oak Realty, The Grubb Company, Frank Howard Allen and Coldwell Banker.
 
We've cleaned windows for famous people and star businesses and organizations.  Each year we do the headquarters for Consumers' Union in San Francisco and each month we do all the  Andronico's stores in the Bay Area.  We did the post construction clean-up for the Chabot Space and Science Center, each year clean windows for the author of "Men Are From Mars, Women Are From Venus"and for world class athletes.  Each trust that we will do the job right and on schedule.

"We've been very pleased with your services and would strongly recommend you to other companies for any type of window cleaning. The fact that you've been able to come out at a moment's notice occasionally has been very helpful at those times."
