Yes, both our company and all of our technicians are fully insured.
We recommend having your windows cleaned twice a year to prevent hard water accumulation and to extend the longevity of windows and screens.
All windows are cleaned by hand individually. We use standard window washing supplies, squeegees, buckets, and soft cloths.
We use a combination of mild soap and water to wash your windows. It is environmentally safe and it will not leave streaks; it is also non-abrasive.
We do not use any acid based products, ammonia, or vinegar.
Final price is determined before the start of the job. You can view our price list and price guide, which can be found on our Window Washing, Gutter Cleaning, or Power Washing pages. Or, use our Quick Quote Pricing Calculator!
Yes, we typically like to do both inside and outside on your first service. After your first cleaning of the year, you can transition from inside and outside window cleaning to outside only. While inside windows may stay clean for a longer period than outside windows, smoking, children, pets, and other factors may contribute to your need for indoor window cleaning.
Typically, window cleaning can take anywhere from 1 hour to 6 hours, depending on the size of the house, number of windows, and when your last cleaning took place. Storms, screens, or French-style windows will add to the cleaning time.
If you are a first-time customer, we recommend that you are home for your window washing appointment. With this, we can offer a full price quote, ensure the service is to your satisfaction, and answer any questions you may have.
If you are having your gutters cleaned, you aren’t required to be home for your service. We can leave an invoice at your home after your gutters have been cleaned for your convenience. We do ask that you mail in payment within 5 days after the service has been completed. We also ask that you provide a phone number in case any questions should arise.
If you are having your outside windows cleaned, we don’t require that you’re home for this either, as long as storms and/or outdoor screens can be removed from the outside. We do ask that you mail in payment within 5 days after the service has been completed, as well as provide a phone number in case any questions should arise.
We offer same- or next-day service when available. During the busy season (spring and fall), we do recommend that you try to give one week’s notice when possible.
We offer:
8 A.M. -10 A.M. Arrival Time
10 A.M. – 12 Noon Arrival Time
12 Noon – 2 P.M. Arrival Time

Yes, we have Saturday appointments available. During our peak season (spring and fall), we offer Sunday appointments.
We bring our own equipment and supplies. We do ask that all blinds and/or window treatments are open or tied back before our arrival, and that there is a clear path to each window. Please remove any breakables or nick-knacks on or around the window area.
Most maid services use a product like Windex and paper towels, which will not clean your windows. Instead, it will rub the dirt around, which will create a static charge that will attract dirt and dust to your windows—but worst of all, it can scratch the glass. Our window washers use only professional window washing tools and equipment.
There are a few main things that will cause your window to become dirty:
- Dust
- Dirt
- Pollen
- Insect droppings and nest building
We try to closely monitor the current weather conditions. If the weather is questionable on the day of your appointment, please contact our office toll-free at 1-800-820-6155.
No, not if they are clean. When your windows are clean, you don’t have any dust or dirt for the water to adhere to. However, if your windows are dirty, rain simply attaches itself to dirt that is already there, often making them look worse.
The main reason for foggy windows is that you can have a broken or damaged rubber seal. The rubber seal is what keeps the gas between the pains from escaping. Your windows will look foggy because moisture gets gets trapped in between the panes.
We recommend that screen be cleaned once a year.
We cannot guarantee that all stains or spots will be removed during the cleaning of your screen. However, we will do our best to try to remove as many of the stains as possible. Screens that are not cleaned on a regular basis will accumulate a buildup of dirt and grime that can cause stains and spots, and this sometimes becomes permanent.
No, tracks and frames have an additional charge. Basic window washing includes the cleaning of the actual glass and wiping down your window sills. Tracks and frames are priced separately.
It is much more time-consuming to wash each individual pane one at a time as opposed to washing the whole window in one motion.
The floors will be covered with a drop cloth or towels to prevent anything from dripping on the floor. The workers will also be careful not to mark up your walls.
Out of respect for you and your home, our window washers will either remove their shoes or wear shoe covers.
Yes, we are fully insured. We hire only responsible individuals, and we also perform background checks.

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.
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.
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.
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.
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.
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.
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.
It was great. I have no complaints. I will use them again.
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!
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.
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.
I got service the same day I called. They were very prompt. They did a good job. I will call them again.
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.
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.
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.
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.
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.
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.
They washed all my windows, inside and out. They cleaned screens and skylights. It was fabulous and fast work. Excellent crew. No complaints.
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.
