They are very professional and did a fantastic job. I have used McMahon Window Washing for 2 or 3 years and have recommended them to others in my building. If I need to reschedule because of rain, they are very accommodating. They always leave everything neat and clean.
Michelle and Greg in Chicago
McMahon Window Washing did an excellent job, and they were really professional and nice as well. I highly recommended them. I have a 2-story Victorian-style house with complicated windows, storms, and screens. It normally takes my wife and I 2 full days to clean our windows (we are both in our 60’s); it took them 4 hours. We will never clean our windows ourselves again. I will call McMahon Window Washing to do it for us. It was great. A job well done.
Ralph in Oak Lawn

The workers showed up on time. They worked quickly and efficiently, and they were very nice. They cleaned out the gross cicadas and leaves in my gutters. They did a fantastic job.

Nancy in North Barrington

Very friendly and helpful when setting up my appointment. I made a Saturday appointment for window washing. The window washers showed up on time. The guys went right to work; they were done about an hour later. They didn’t seem to have any trouble with the various shrubs around the house. They washed the inside and outside of the windows. It has been 3 weeks, and they still look great.

Dave in Elmhurst

They did a great job! I called them in the fall to have my gutters cleaned. I work full time and I am a mom of 3, so I don’t have much free time on my hands. I could not be home for the gutter cleaning appointment; they told me that they would do the work in the next few days and then leave me a bill….When I came home from work that day…much to my surprise, I discovered they had already been there to clean out my gutters.

Sara in Naperville

This company is the best! This was the 3rd time that I have used them. The two men were very nice and also on time. They were very professional and polite. Our house is surrounded by a lot trees, and there are a ton of leaves and twigs to be cleaned out of the gutters. They hauled away all the leaves in bags for me. They did a great job. As for my windows, they look so clean and shiny! The whole job took about three hours, and the men did not take a break. I am a very happy customer and recommend them to everyone and anyone!

Kathy in Lombard
They washed all my windows, inside and out. They cleaned screens and skylights. It was fabulous and fast work. Excellent crew. No complaints.
Sandy in Crystal Lake
I got service the same day I called. They were very prompt. They did a good job. I will call them again.
Debbie & Baby Ella in Hinsdale
Two men arrived exactly on time; they did a perfect job and were extremely respectful with our property. We’ve tried a couple other window washing companies in the past and were not happy. I saw a coupon from McMahon and I thought we would try them. We were most satisfied with this company. I will only use McMahon from now on. Our windows are not easy to access and these men never missed a beat. We found this to be a very professional company and will continue to use them in the future.
Gwen in Lake Forest
They were on time and very good at doing their job quietly. I have a baby, and they were good about making the least amount of noise around the area where my baby was sleeping.
Nancy in Orland Park
They are really great. They fit me in right away when I said I was having water problems with my gutters. I guess for a new customer to call out of the blue, that was very nice of them to do that for me. I was so impressed with the two men that came out to do my gutters that I asked if they had time to do my windows…and they did….I have the cleanest windows and gutters on my block…They look so good that my neighbors have called to book appointments with McMahon Window Washing for themselves.
John in Chicago
They have a good service. We were very pleased. I never knew that my windows could look that good. They are efficient and neat. I will rehire them again and recommend to friends.
Alice in Huntley

It was great. I have no complaints. I will use them again.

Theresa in Carol Stream
I was very pleased with the work the men did when they cleaned my windows. I thought the quality of the cleaning and the price was excellent. I recommend them and will use them again.
Sarah & Don in Palatine

The crew was friendly and they worked very hard. They cleaned about 50 windows. Nice guys—they even did my garage windows. They have a customer for life.

Nikki in Barrington

I called on a Saturday and was given a quote for the work over the phone. It was scheduled for that next Monday afternoon. It took the 2 workers about a half an hour to 45 minutes completely clean out and flush my gutters. They swept leaves, branches, and other debris off my roof, and picked up most of the debris and took it away. They worked very quickly, and were extremely nice men.

Nicole from Oak Brook
The two gentlemen were on time; they were polite, worked very quickly, and did a great job. My windows have never been so clean. They were done in just under 90 minutes. We were very satisfied with their work.
Ron & Marge in St Charles
They did the job in about 2 hours. It was an excellent job. They were right on time. I thought the price was excellent too. I was very happy with the whole thing.
Jan in Winnetka

The crew was friendly and they worked very hard. They cleaned about 50 windows. Nice guys—they even did my garage windows. They have a customer for life.

Heather in Wheaton
I called to schedule an appointment at the last minute before a party, which was in a few days. They were able to fit me in at the last moment. The workers were very efficient and careful in their work, which was finished in one hour. Afterward, the windows really sparkled for my party.
