David is a solidly reliable, dedicated, hard-working guy. If he says he will be somewhere at a certain time, he will be there 20 minutes early. Very conscientious in his work, and very humble and unfailingly polite, he was a delight to have as a contractor cleaning all my windows, inside and outside. He even made the skylight look invisible! I highly recommend him for all your window washing needs, whether a picture perfect window at your home/office, or your skyscraper downtown.
I rarely comment on home services, but my total experience with DND Window Washing was exceptional from start to finish. I even received a follow up call to ask how everything looked. I would not hesitate to recommend it to my friends and neighbors. There's no doubt that I will use them again in the future. Great Job David and crew!!
I have found the workers to be very courteous and friendly. They are also very neat in their work.”
