"Very quick service. Good quality work. High value for our money as far as I m concerned. Should have had them do windows at same time which was also a reasonable price. Will use this company again."

Customers say: Terrific value

"Glenn and Matthew were extremely nice and attentive to our needs! They first spent time walking around the house and shed area to see exactly what we wanted to accomplished. Our house and shed came out beautiful...just like new again! We were so happy we did not have to clean water spots off the windows when they were done power washing. Thanks guys for a spectacular job! You get a rating of A+!!!"

Customers say: Quick response

"Kevin and his crew showed up up for us on a very last minute request. He was very helpful and willing to make it work when we were under a time crunch. We had called several companies hoping to get someone out, and he was one of the few who was willing to come out and actually perform the work, rather than just come for an estimate only.  Furthermore, he was prompt in returning our initial phone call, and called us again before he planned to arrive at the house.
The crew was quick, efficient and I believe we were given a very fair price for the amount of windows- cleaned inside and out on a three story home. 
Thanks to Kevin and his crew for making it work for us.
A company who caters to their clients is a real bonus these days, when so often it is the other way around.

"KO cleaners did a terrific job on our house. We were moving out and needed all rooms, bathrooms, kitchen and appliances cleaned. The house truly sparkled when they were done. Appliances looked brand new. I would recommend them to anyone. 5 stars!"

"I recently had New England Shine soft wash my entire house, gutters included, and I couldn’t be happier with the results. My home looks brand new. Every trace of grime, mildew, and buildup is gone. Beyond the incredible work, the owner made the whole experience a pleasure. He’s genuinely down to earth, easy to talk to, and clearly takes pride in doing the job right. He gave me a great price without ever cutting corners on quality, which is hard to find these days. I’m already planning to have him back in the next few months, and I’m especially looking forward to their deionized water window cleaning next, from everything I’ve heard, it leaves windows completely spot-free. If you’re looking for a soft washing company that’s professional, fairly priced, and run by someone who actually cares about their customers, New England Shine is it. Highly recommend!"

Window Cleaning FAQs, answered by experts

Professionals remove dust, allergens, and stains while preserving fabric integrity and enhancing the appearance of window treatments.

For a standard 1,000-square-foot home, you should expect your window cleaner to take between 1 and 3 hours to clean all of your windows. Of course, the size of your home and the number and size of the windows you have will play a role in the timeline. Certain styles of windows—like picture windows, which have no moving parts—also take less time to clean.

A professional cleaning service generally takes a few hours, typically between 2 to 4 hours, depending on the property's size and the severity of any stains. Keep in mind that wet cleaning methods will require additional drying time.

Unless it’s written into the purchase agreement, there’s no legal obligation that a house you’ve bought has to be clean before you move in. The previous owner is generally required to sweep the house, but that doesn’t guarantee everything will be spotless upon your arrival. If possible, discuss the cleaning requirements with the real estate company before moving in.

Window cleaning depends on how the cleaning service defines their deep cleaning tasks, so pay attention to the details. You certainly should make sure window cleaning is included in the package. Some services will include it as an add-on, so you may have to pay extra. Find out if the cleaning includes interior windows only, or interior and exterior windows. Exterior windows may cost more.
