About Us

In 1927, Charles Knoff began cleaning windows under the name of Allston Window cleaning company. In 1981, the company’s name changed to M. Annis and Sons, named after Morris Annis, son-in-law of the late Charles Knoff. Four generations later, M. Annis continues to be the choice of home owners for cleaning windows, gutters, drapery, home repair, upholstery, painting, pressure washing and snow removal.
