  • This is absolutely an outstanding company! Rob and Valerie are wonderful, professional people that have built their business on courtesy, proficiency, punctuality and doing an amazing job in cleaning our windows. For years they have proven that their concept works and we have enjoyed seeing the World a little bit cleaner whenever they get done. You couldn't find a more qualified company and highly recommend them to anyone."
    • Larry T.
  • Fantastic experience with this family owned business. They're fast, thorough, courteous and fairly priced. We're so happy we schedule them on a regular spring/fall basis. Even their work vans are spic 'n span."
    • Paul J.
  • This team was amazing! We moved in a year ago, I don’t think these windows have been thoroughly washed in over 20 years—they were bad. But today, oh my! I can see clearly now and it feels so good to have all that gunk gone. They were timely, efficient, kind, local, and very diligent. Their pricing is reasonable and I am very happy to recommend them to anyone!"

  • I have used Rob and Valerie for years. I have tried to mimic their techniques to clean the windows, but fail miserably. They get everything so spotless, it is amazing. I also used Rob a year ago with a house that I was rehabbing to sell. The finishing touch was getting those windows cleaned and the results were once again, perfection."
