Colorado Window Cleaning, Inc

He did a good job of communicating the schedule, very professional, and did a great job-thank you.

On time, stuck to negotiated price, fast efficient and did a great job.

Denny's crew did a fantastic job cleaning our windows!  It'd been five years since our last professional window cleaning, so they had to deal with an embarrassing amount of grime. Their motto is "Windows so clean... you'll think they're open" and I can attest to that! We're getting ready to sell our house, so Denny's ability to get us into his schedule promptly was a huge bonus. I would definitely use his services again, and will recommend him to all my friends. Thank you Denny and crew!

excellent job, especially on screens.  Price per window pane was very good. Highly recommended.

Denny responded quickly to my request for an estimate, and the estimate was very reasonable. We scheduled an appointment for him to come clean my windows, but when he found he had time to do the job a day earlier, he called me to make sure that was OK. I really appreciated that, and the newly cleaned windows look fantastic!

Denny and his team are fantastic! They were so incredibly wonderful to work with. They were professional, thorough, prompt, and thoughtful to our schedule and our pets!!! I have Denny clean my office windows as well. He is always respectful of our office schedule and does an incredible job. I highly recommend Colorado Window Cleaning for all of your window cleaning needs!

All I can say is awesome. Denny was on time, very professional and just an all around great guy. He was very thorough and neat and genuinely cared about his work. He carefully moved any obstacles in front of windows and was careful to put everything back just the way it was and he used a drop cloth and wall protector on his ladder at each window. Our windows look fantastic.

They cleaned all of our windows and screens.  We have very large windows and Denny did great, he didn't waste any time getting the work done.  He told me today that he also repairs screens if you need it.  I can look out our windows and feel like nothing is there.  My wife is a nurse and a neat freak and she thinks they did great.  He cleaned up after himself and wore shoe covers when in our home. Denny was very friendly and professional.  I would recommend him in a heartbeat to anyone who needed their windows or screens clean.  He did really quick work, he estimated that our house normally would take 5-6 hours and it only took him 3.5 hours. He sent us a reminder for the appointment 2 days in advance.  I would give an A+ if I could.

Rolf is extremely professional in the way he handles his business, with excellent communication and reliability. He is also extremely personable and respectful of your home, so I have total comfort having him in the house, even if I'm not home.
I only wish it was in my budget to have Rolf here to make my windows sparkly every month, especially living in dusty Colorado!

Rolf, owner of Colorado Window Cleaning, did a great job cleaning my windows and screens. He was on time, cleaned up after himself, wore booties since the carpets were just washed and even cleaned off my back porch because of a pile up of debris. I didn't ask him to this task, he did it on his own. He left the windows so clean, that it was hard to decipher if the window was closed or if it was open. The screens and window tracks and window sills were also cleaned and he did an excellent job with everything. I am definitely using him for all my future window cleanings. I highly recommend that Rolf clean your windows!
