Very professional nice workers I highly recommend to use this company for your window cleaning power washing

My windows are so clean it looks as if there is no glass in them! I meant to have Andre clean just two windows, but when I saw how great they looked when he was finished, I asked him if he would clean five more. Andre is very buttoned up and professional, also very nice and pleasant to work with. I highly recommend Collins Window Cleaning! read more

Living in a studio rental in Park Slope, window cleaning is an expense that hasn't always been on my list of priorities. However, the transformation has been like night & day. The highlight of the experience was Andre's personality. He was professional, punctual, and had a great sense of humor. Price was very reasonable and the return well worth having huge windows perfected internally and externally. If you have a small space, the result is transforming. Highly recommend. read more

Ricardo was great! He was fast, thorough and left my windows spotless. Also fixed one of my faulty windows while he was at it. I prepared shower caps for his shoes but he even brought his own shoe covers. Would definitely use these guys again. read more

Collins was very accommodating to our schedule. We got an appointment over the weekend and they did a superb job with cleaning our windows. Very decent prices and gave very good advice about what is needed. Really nice guys on top of everything. Don't hesitate to go with them. read more

Excellent service and very decent prices. Andre and his guys were lovely to have in our home, and a pleasure to work with. I did a lot of research and price comparison, as we had some tricky skylights that needed cleaning. Andre found a way to clean them after 2 other companies had told me it was impossible. I cannot recommend him highly enough! Thanks! read more

This was the worst experience i've EVER had with a contractor working in my home. The owner spent a long time in advance of the job asking me to list every window that needed to be washed. When he showed up one and a half hours LATE, he had no idea what the scope of the job was. He left one man and told me the job would take two hours, when, in fact, the job took three and a half hours. The window washer had a GREAT DEAL OF DIFFICULTY putting my windows back into their respective grooves after tilting them inward to clean the surfaces that faced outward. I actually had to help him. I will NEVER use this company again. I have never posted a review on YELP before, but I felt it was important to warn others about this dangerous incompetent company. NO STARS. read more

Andre did a great job! This was the first time we've ever had our windows cleaned and it is SO WORTH IT. If we had done them ourselves, it would have taken hours of time. Andre came in (very prompt), cleaned all 8 of our windows (plus our skylight that opens up) in under an hour. He's very nice, conversational -- and he was totally chill when my little dog kept barking at him. I think we'll have him start coming at least twice a year. It's a lot less expensive than I thought it would be. Having clean windows lets more light in and just looks nicer. I echo another reviewer's statement when they said it looks like there's no glass in the windows. I just went to close an open window, and then realized it was already closed! He's a local, owner-operated business and I recommend him without reservation. read more

tried the rest? collins is the best, and you will find no more courteous, energetic, and comprehensive window washer in all five boroughs. andré arrived on time. no complaints about the difficult street parking that we hear constantly. prices were as quoted. for a nominal extra fee he removed the screens and cleaned them downstairs. wow! i'm sure they had never been cleaned before. top notch. let there be light! read more

My girlfriend Ashley recommended Andre and all i can say is WOW!! What a difference. My windows look amazing. I highly recommend anyone that needs their windows cleaned to call Andre. He is professional and extremely nice. read more

Andre is not only a perfectionist, doing whatever it takes to get a window clean, which is not always easy with accessing some of the windows on a brownstone, but he is just a lovely person and a joy to have in your home. Cannot recommend enough. My windows have never looked better! read more

Fast, thorough and well-priced. Andre was super sweet and great to chat with. Highly recommend!

Andre a great job cleaning my gutters and now I don't have to worry about heavy rain overloading the drain spouts. He also cleaned the vinyl siding on my house for no extra charge. He is a true professional and I would definitely recommend him to anyone needing his services. read more

Collins was great to work with. Cindy responded really quickly to my request and was able to fit me in within a few days. Andre showed up on time to the appointment, so I was able to get to work on time which is rare when dealing with contractors. The windows themselves are spotless, and I had no clue they could be so perfectly clean - the difference in the amount of light that now gets into the apartment is amazing. I'll definitely use them again, and my building was impressed enough with the work that they want to use Collins to power wash the front facade. read more

Courteous, prompt, professional, willing to work with me on the price (I have a LOT of windows), super careful with my furniture and belongings, and did a terrific cleaning job. Thanks so much, Andre and Elijah - it's great to be able to see outside again!! read more

Great window washing. They arrived on time with all their equipment. They did a wonderful job despite the many difficulties my windows present. I have old windows that do not tilt and bars and non removable air conditioners in some windows. My windows hadn't been washed in a while and we have recently undergone an apartment renovation. The windows were coated with grime. High praise, especially for Ricardo who addressed and overcame all the difficulties. read more

Just had a pretty bad experience with this company. I own a dance studio in Brooklyn Heights and this is the 2nd time they are cleaning our windows. The first time around it was $180. The guy tells me on the phone that his prices have increased since then. Ok I get it, I own a business and we need to increase prices occasionally. When he gets here he gives me a quote of $270. That's quite an increase (50% to be exact). So before he does the job I ask him if there is some sort of price break if we were to schedule a cleaning every 3 months. He says it would be $200 in that case. Which is reasonable. After he's done the job I go to pay him the $200 and he tells me it's $270 for today. Why can't I start the contract today? I'm ready to give him $200 every 3 months for the forseeable future (I have 9 years left on my lease). As a fellow business owner, I'm scratching my head. If a client comes in to take a class at my studio and wants to sign up for a membership, I'm not charging my client a higher rate for today's class. I'm starting the contract right then and there to lock in that income indefinitely. (And also to please my customer). When I asked this question of him (why wouldn't you want to lock it in?), his answer: "I have a lot of customers" ...lovely. Plenty of other vendors out there, give your business to someone who is going to value it. (To be fair, they get 1 star for squeezing me in on same the day I called.) read more

Collins Window Cleaning was a fabulous find for me... I needed LOTS of windows cleaned and sidewalks and patios power-washed. They did a great job, were extremely pleasant to work with and the price was reasonable. Thank you, Andre! read more

I just had the most pleasant experience with Collins Window Cleaning from start to finish. I decided after 10 years in my Brooklyn house that it was time to have the windows professionally cleaned. I did some preliminary research and decided to give Collins a try. I'm so glad I did. I set up the appointment with Lisa who answered all of my questions. Andre showed up on time and was as kind, helpful and professional as could be. He and his colleague cleaned the heck out of my filthy windows. It seriously looks like the windows are open they are so incredibly clean. All for a fair price. Definitely use Collins for your window cleaning needs, you will not be sorry!! read more

I cannot say enough about Collins Window Washing. Andre is extremely professional and excellent at what he does. Our windows are old. We have storm windows in addition to child guards...not an easy situation to deal with. Andre came in, navigated the situation and managed to make our windows look amazing. Even my 5 year old was impressed. Thank you Andre! read more

Andre came out on a Saturday and I don't think those are his regular hours, so I was really grateful for that. I've never had a professional window cleaning before and I am so happy with results. They looked so awesome when he was done, I couldn't even tell there was glass in the windows! He came on time, was so professional and very reasonably priced. I would definitely call him again and recommend him to family and friends. Thank you! read more

Couldn't give a higher recommendation for Andre. He does a great job. He's super courteous, fast and has great prices. We'll be using him again next year. read more
