Ralph was terrific. Thorough, professional, just great.
Great experience with Unicorn. Did a great job! Windows looks spotless inside and out. Kept a neat and tidy workspace as they worked through our house. Pleasure to work with!
Update- We had Ralph come do the windows and gutters at our new house and he again did a fantastic job! Ralph did a great job cleaning our windows in our 2-family. He was quick, thorough, and affordable!
One gentleman came to clean 11 windows plus storm windows. He was efficient and did an excellent job. This is the second time I have used this company and I would give them a 5 star rating! Highly recommend their work.
Prompt, professional, and thorough cleaning at a reasonable price.
Great service at a good price! We'll definitely use Unicorn again.
The is the 4th or 5th time these guys have done my windows and gutters. They are fantastic and the place is neat and tidy when they leave. HIGHLY recommend them.
Always exceptional, and so easy to work with. We have a very complicated property and Unicorn has specialized equipment and expertise to do our huge curtain wall windows. Highly recomended !
Amazing work! Lovely guy! And so fast! I will be hiring them again! 🪟 ✨ ✨✨
It was great having Ralph come to clean our windows! He did much more than just that; fixed the old broken ropes in the windows, repaired a broken window, and made the windows sparkle. Then he worked on the gutters that were leaking, screwing them back up and siliconing so they won't leak. He's very thorough,…
great experience- on time, professional and good value for the money and super kind team. It’s my second year using unicorn and definitely not the last!
Fantastic service!
Windows are sparkling. Attentive, responsible service. Will use again.
Kade did a great job on our windows. I got a text when he was on the way and he very efficiently made his way around our condo and cleaned all our windows inside and outside. The price was very affordable. We would definitely hire Unicorn again.
Ralph and his assistant did a terrific job. The windows look great. They cleaned up all the leaves from the gutter cleaning. Ralph was a pleasure to work and schedule with. I will look forward to working with them again!
They were neat, efficient, and my windows look great. Cleaning the interior window sills was very nice also. Will use them again. What
Expert window cleaning. Appreciate the fact that environmentally friendly cleaner was used (soap and water). Windows sparkle.
Best around!!!
I was impressed with Ralph's expertise. He did my small home without disturbing or having to move things or knocking things over and he is a big man. A job well done. I would recomment Unicorn.
Hard working, professional, honest
Our windows are perfectly clean after a visit from Unicorn Window Cleaning. Ralph and his team are a pleasure to work with: friendly, professional, and skilled at the services they provide. Highly recommend them!
Kane did a great job + he was thorough and discreet. We'll have him back!
These guys are AMAZING!!! I never knew windows could be this clean. They worked really hard, were extremely polite, punctual, and professional. I cannot say enough for Unicorn. PS - I never bother to write reviews but this was just too spectacular to keep to myself.
The attention to detail was amazing! I couldn't be happier!
Person who came to clean the windows was extremely conscientious, told us about any broken windows he found. Excellent work, service, and professionalism.
The men where polite, friendly and worked hard to do the best ever job cleaning our windows. I’ll use them again next year.
The owner of Unicorn Window Cleaning, Ralph, is extremely nice and professional. He did a fantastic job. I would highly recommend him to anyone who needs window cleaning in the future.
All around excellent experience!
Ralph went above and beyond. He was extremely honest and did a fantastic job.
Phil did an excellent job!
Great communication and quality job at a very reasonable price!
I hired Unicorn to clean the windows of my house. They hadn’t been cleaned in years. Unicorn did an excellent job. They were responsive, polite, professional, reasonable and high quality. I liked them so much I want to clean my windows regularly from now on. Highly recommend!
Very responsive to email queries. Was able to get an appointment for indoor, outdoor window cleaning. Came a time. Did not make a mess. Will reuse them at spring time.
Don’t look elsewhere! Unicorn is all you need 🦄
