Could not have asked for better. Jon was attentive and professional during negotiations. His guys were prompt, neat, and extremely competent. They left everything… in the same condition as they found it. Highly recommend.

Jon’s Window Cleaning is always professional, punctual, communicative, efficient, and does a thorough job. I had exterior windows done and next time will schedule exterior and interior. Fantastic work!

Excellent, I have no restraint when it comes to giving critical review and in this case fully support all of the other positive reviews for Jon’s Window Cleaning. Staff were professional, quick, and performed a top job.

“In a time when true “home grown”, owner-operated, professional, quality, customer service companies are becoming more and more scarce, it is reassuring to know there is a firm that remains committed to the “customer first”! Clearly built upon integrity, it is a genuine privilege to have such quality staff attend to our needs! Equally important is the comfort to know that Jon’s team can work around family and friends whether they are home or not. This speaks to the impeccable high standards Jon and his staff hold themselves to. Yes, it was a genuine pleasure from the initial introduction and greeting at the front door to their completion and sincere farewells! I am walking around our home singing ‘I can see clearly now, the grim is gone’!! Want excellent quality service the first time? Call Jon and his team of dedicated ‘window warriors’!”

I am a contractor that owns a stucco remediation company. We asked Jon and his crew to clean all the windows and doors for us. The client said their windows have never looked so nice.

They did a great job! I will use them again and highly recommend Jon’s Window Cleaning! The guys did an amazing job on my dirty old windows and storm windows. The house actually sparkles.

Jon came out gave me a quote for the work. The price was very fair and we agreed on a date. Joe and Drew showed up on time. Very professional, and did a great job. The windows never looked cleaner.

“I am thrilled with the job Jon, Brandon and Nick did on the windows of our home. There is a vast difference in the way the house looks and feels to us, inside and out. The team was incredibly kind and considerate, and very respectful of our belongings. We appreciate how careful they were to see that the ladders were clean, that they cushioned the ladders leaning against the house, and used drop cloths throughout the house. I would say that Jon and his team exceeded our expectations, but that really doesn’t go far enough. I would rate the experience and result as perfection. Many thanks to Jon, Brandon and Nick. We’ll see you next fall.”

“I have Jon and his professional team take care of my gutters and window cleaning. Jon is very responsive and offers a very fair price for the great work that they do. The windows look amazing when they are finished cleaning them!! I have several difficult to reach upper story windows that would be way too dangerous for my husband and I to clean on our own. Speaking of dangerous, our very high gutters are very difficult for us to reach safely! Jon’s team does a great job cleaning out the gutters and leaving the property clean. Today I had an emergency with an overflowing difficult to reach gutter. The water was coming into my basement and John rushed over to unclog the corner at the downspout. He was so responsive to my call for help that he saved the basement from getting flooded.”
“After years of trying to keep up with annual screen cleaning and window washing myself, I finally decided to hire a professional. Jon and his crew were most certainly professional. From beginning to end, Jon was responsive and reliable. His pricing was competitive. His crew arrived promptly and worked diligently. By lunchtime the screens, interior/exterior windows and sills were spotless. My husband and I are thrilled! Jon’s service was top notch. I plan to reach out to Jon next year to schedule again. I highly recommend Jon’s Window Cleaning to others in the area!”
The windows look great, Service was done in a professional manner. There was nothing to clean up after he finished. We’ll be glad to have him back, the next time the windows need cleaning.

Jon’s team did a great job this week. Will definitely have them back routinely. The windows look great and having the screens removed and washed definitely worth it. Good team!

Terrific. They showed up on time and were efficient, yet did a thorough job. I have a lot of windows in my house and they all look great. I will definitely hire the company again next year.
