clean windows, so i had them clean all the outside windows on my house, which has about twice as many windows as most houses. they quoted a price and scheduled a time. they showed up on time to the minute, and did an outstanding job on the windows. they even took a little longer than estimated in order to do a good job, and did not charge any extra. it is great to have a contractor show up on time and stick with the quoted price. highly recommended.
