Jason was very courteous and prompt. I really appreciated his communication skills. He spent a lot of time on our gutters to make sure that it’s cleaned properly. Would highly recommend him!

Cindy Y. - Colorado Springs

Every winter water would pour out of our downspout and pool then freeze on our driveway causing a hazardous condition. Jason and his team rerouted our downspout to redirect this water into our backyard saving us from broken hips. Thank you Jason!

My windows shine after COS Exterior Services’ fine work. Jason is professional and thorough, knowledgeable and personable. You can entrust your windows to him – he’ll do an excellent job for you!

Barb K. Colorado Springs, CO

Jason, with COS Exterior Services, has earned my trust. He’s cleaned the windows of my home, and I refer him to my own customers for gutter cleaning. Since I own a business, it says a lot about Jason’s professionalism that I trust him with my own clients!

Tracy B. Peyton, CO

We’ve had Jason out twice so far. Once he cleaned out our gutters and the second time to clean all our windows. Both times, he’s done a fantastic job. He did both jobs for a reasonable rate. Highly recommend!
