With a focus on reliability and safety, we help businesses maintain a polished appearance while extending the lifespan of their windows through proper care techniques.
Screen Cleaning
Our screen cleaning service removes dirt, pollen, and debris from standard and oversized window screens. We clean both interior and exterior screens, including specialty styles with internal latches. Pricing starts at $4 for screens under 3' and $10 for oversized exterior models. Regular screen maintenance improves indoor air quality and enhances visibility while protecting your investment in quality window treatments.

Excellent window cleaning service! Peak Window Cleaning are knowledgeable about windows in the high elevation areas of Colorado. The men were respectful of our property, protected furniture, no drips, took care around furniture, and left us with gorgeous views! If you are looking for a longtime reputable company then PWC is your company to contract! Oh, and the prices are very reasonable!

I live in beautiful Evergreen and Peak Window Cleaning has cleaned my windows twice for me. We have the most spectacular view of the front range from our livingroom and having spotless windows is pretty important to me! Both times they did a quality job and if you can please me with this sort of thing you can please just about anyone! Not only are they hard working but professional and friendly! I would highly recommend them to friends and family. My only regret is that I didn't find them sooner! Kay Jacobus, a very satisfied customer

I'm so impressed! Communication with Peak was excellent, they fit me into the schedule VERY quickly, and Nick and Max were polite and friendly and did a great job on our window exteriors. This is the best window cleaning experience I've had, and I would gladly hire Peak again! Service: Interior & exterior window cleaning

I contacted Peak Window Cleaning to clean both inside and outside of our windows. They responded same day and were able to get us scheduled in a timely manner. The young men who performed the work were on time, polite and thorough. This is the best customer service we have had with a service company in Evergreen. Do not hesitate to use Peak Window Cleaning!

I happened to catch them at my neighbor's house and the owner estimated the job on the spot. Very reasonable price and we were on the schedule to be completed within a week after accepting the estimate. As others have said: Spotless. Not a single streak, which I cannot say for my two previous window cleaners. The technician was the most careful and thorough that we have ever employed. If you care about the safety and conscientiousness of the people doing the job, I'd say this is your window cleaning company.
