David was professional and friendly. He did a thorough job cleaning my roof and gutter. He went extra mile to ensure the job is done before the new year and offered me a big discount for the inconvenience of unavoidable schedule changes. It's a rare example of unreasonable hospitality that I have received as a customer! read more

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 window at your home/office, or your skyscraper downtown. read more
