Hi, I'm Kirk Kanitz!

I've been a top rated professional window cleaner for 18 years.

Now I'm happy to offer residential and commercial window cleaning in Glenwood Springs and the Western Slope area. As an owner operated company, I can provide my personal guarantee that you'll not just love my work, I'll be the last window cleaner you'll ever need to find.

My work is backed by a 100% money back guarantee and rain guarantee.

Your residential window cleaning expert.

I bring 18 years of top ranked window cleaning experience to every job. You’ll always get me, not employees!

I pride myself on being the type of service person hundreds of customers have trusted and felt comfortable letting into their homes. I love what I do and always strive for perfection. The gentle dance of breezing through your home cognizant of fragile’s, valuables, and white carpet is a skill honed over nearly 20 years cleaning windows in thousands of homes. You’ll always get the best results from a long tenured professional who owns the business and does his own work. There is no substitute for experience!

  • ❑ Owner operated
  • ❑ Fully insured
  • ❑ All work guaranteed


Worried about it raining after I clean your windows?

Worry no more, I have your back with my rainy day guarantee.

The experience you need for your commercial window cleaning projects

With 18 years experience, I can tackle any project.

I believe the key to my success as a window cleaner is the experience and expertise I bring to every job. Employee based companies have neither the quality or commitment to compete with a long tenured owner-operator who cares about every detail of his craft.

  • ❑ Sparkling clean store front windows
  • ❑ Increased sales
