A homeowner with more than 20 windows and doors praised Sean's cleaning, punctuality and efficiency in a July 2026 review of Crystal Clear Window Cleaning. The company says it is locally owned and operated in Spencer, Massachusetts, and provides residential and commercial window cleaning plus gutter cleaning in Worcester County. Another homeowner described glass across three levels of their house in a May 2026 review. Some windows had been out of reach for their own cleaning. They said Sean's price was more than fair and that the glass still looked clean two months after his visit. An April reviewer described windows cleaned inside and out, called Sean trustworthy and said they planned to have him back yearly. A May 2026 customer said their parents had recommended Sean, then praised his communication, professionalism and the cleaning of their own windows. They planned to use him again in the fall. Google reports a 5-star average from six ratings. Earlier accounts also described the service directly. In October 2025, a customer said Sean came out right away to provide an estimate and arrived on time on the scheduled morning; they described feeling comfortable having him in their home. A March 2026 reviewer praised his thoroughness and efficiency and said they would have him back.
Sean did a phenomenal job cleaning my windows and doors. My house has 20+ windows and doors and they have never looked this clean. In addition, Sean was punctual and efficient throughout the process. I strongly recommend his services and will definitely use his services again.
Sean’s work is amazing! He was recommended to us by my parents, whose windows have never looked better. Sean’s communication and professionalism are exemplary. He cleaned our windows impeccably. What a difference! Thanks, Sean! We will definitely have you back in the fall and beyond.
My house has a lot of glass in three levels. Some of which I never cleaned because I had no way to get up that high. We’ve done the other windows a handful of times since we built the house 20 years ago. Always never satisfied with the job we did. So I saw Sean’s Crystal Clear sign and gave him a call to get an estimate. Price was more than fair and I can’t describe how clean my window's are!!! Literally our glass is invisible!! I’ve never seen windows this clean honestly. He did them 2 months ago and they still are amazing. I highly recommend Crystal Clear Window Cleaning!! Having Sean do our house was the best thing I’ve done to it in 20 years! I’m just disappointed I didn’t discover him earlier!! Thanks again Sean!! See you next time!!
Highly recommend Sean with Crystal Clean Window cleaning. He did a fabulous job and my windows have never looked so clean! Excellent service, personable and trustworthy. Windows are done inside and out. You won’t see me up on a ladder doing what he did. He will be back yearly for sure.
I can’t recommend Sean with Crystal Clear Window Cleaning enough! He was thorough, efficient and my windows have never looked better! We will 100% have him back!
