Knock On Glass

I called them because I needed a glass top for my dining room table. They came in the same day to take measurements and their price was unbeatable. They are extremely professional and easy going. I had wanted to install a shower door for a while but I didn’t feel like dealing with contractors and such but since they were already here I asked them about it. They took measurements and gave me estimates on the spot. We decided to have it done by them right away. It has been the best experience I’ve had when it comes to home improvement.
Vitaliy and his father are really wonderful people and they respond to any questions you may have right away. Even after the job is done. HIGHLY recommended!

We have 2 curious cats (too smart for their own good), and we had to install an outdoor glass shield on our terrace to prevent them from jumping off. This has never been done before in our building, but Vitaliy was very responsive and knowledge over emails in helping us with designing the glass shield that’s compliant with our condo board and sufficient for the cats. Scheduling the final estimate and the work were very easy as well. Within a week or so once our materials are delivered, we got the glass shield installed in one day! Really happy with the result. Would definitely work with Knock on Glass again for further glass work around the apartment.

I called numerous glass installers /​contractors and only Knock on Glass was able to understand and commit to my unique project.
I had to uninstall, store, and reinstall a glass partition with sliding glass doors in my high end luxury apartment and Knock On Glass totally surpassed my expectations. The team was incredibly professional, punctual, and trustworthy. They helped explain to both me and my insurance company the unique aspects of the project and required work. Vitaliy was incredibly accommodating to my schedule and was luckily able to start the project right away. He overdelivered in speed both times (uninstall & reinstall) and I could not be happier with the end product.
If I ever need any glass or window related work done, I will definitely be calling Knock on Glass.

These guys did first-​class work at affordable prices compared to the competition. They worked with our specifications and were very quick to install. We had a backsplash on one shower, a double-​sliding door on another, and two glass shelves installed. Everything is custom, and the materials they use is of the highest quality.

AWESOME! Overall, very professional, courteous, delivered on time, and responsive!
Vitaliy did a great job with our completing and installing our order (a glass tabletop with beveled edge). Competitive pricing doesn’t mean skimping on pricing, either. From the time I contacted him initially for a quote through on-​site delivery, he was very responsive to all my questions and requests. Thank you SO much for everything!

Finally a contractor who is timely, responsive and does beautiful work! They were so easy to work with from the quote to installation. I love my custom mirrors.

I am somewhat reluctant to write this so soon as my new glass shower door was just installed yesterday. In a world where so often nothing goes right, Vitaliy showed it can be done right. I had a couple of other estimates, one as much as $ 1100 more than Vitaliy charged me.
I emailed Vitaliy after reading all the positive reviews here. Within 10 minutes he responded. We emailed back and forth discussing what I was looking for, then they came out the very next day to measure. Vitaliy and his father were right on time. They measured the space and happily discussed all of the options available. I was still a bit reluctant at this point as he came in so much cheaper than other places, and he required a 50% down when he came to measure. He said at that point it would be 7 – 10 business days for manufacturing. (One other place told me 3 weeks).
At some point in the following days I emailed Vitaliy as my building required a Certificate of Insurance for delivery. Of course, Vitaliy emailed me the completed form the next day.
The last surprise was that the door was manufactured early and they could come out to install it. I think this entire process went down over the course of 10 days from the day I first emailed Knock on Glass to the day they installed it.
Vitaliy and his Dad work together, and they were super professional, courteous, efficient, neat, and affordable. I know this sounds too good of a review to be real, but I assure you this was my experience. In what was an awful bathroom renovation experience up to this point, the final piece of installing a custom shower door was as smooth and flawless a process as could be. Thanks!

Knock on Glass /​Vitaliy did an awesome job with my glass table top. The quality is excellent and the cost was reasonable. He was extremely responsive and professional and managed to fabricate and deliver the top ahead of schedule. I would highly recommend. Thank you !

I need to give them a five star for the wonderful job, thanks Vitaliy and his father.
I live near port authority and have been bothered with the noise outside since the first day started living here, we started to try to sound proof the windows. After endless search the sound proof companies in the city were cityproof and city quiet, obviously they were too busy to answer a phone call it always led me to voicemail. After reading the suspicious good reviews/​bad reviews of those companies on Unilocal I started to try simply looking for window installation companies.
Thanks to Unilocal I found a few options and after contacting I decided to go for Knock on glass since the price and project closing time were perfect. Vitaliy quickly came measured the windows and made the windows for us for the two bedrooms, the whole thing was done within two weeks! From the view of cityproof they take usually 6 months!
He works productively and responds very fast, most importantly he got the job done fast, right with reasonable price. Thanks to Knock on glass we have quality sleeps and quiet nights in midtown Manhattan. I highly recommend him if anyone needs window installation/​sound proof.

Knock On Glass did an excellent job on our glass shower door. I reached out to several companies when I was searching for «glass shower enclosure brooklyn.» Vitaliy was the first to respond and gave me the most reasonable quote of all the companies I contacted.
I really appreciated how easy breezy it was to get started on the project with Vitaliy. He was super responsive by email and phone, especially compared to other companies that took a long time to respond to my requests to schedule someone to come in and do measurements so I could get a final quote.
Since the enclosure adds value to our condo, we did not have to pay taxes on shower door. Vitaliy provided the form and made everything easy on my end.
If and when we upgrade our second bathroom, we will for sure call Knock On Glass.

who know that some glass and mirrors could totally up the value of my apartment. So happy with the professional, clean and beautiful work Vitaliy and his team at knock on glass completed. Love my new shower door and mirror door! Couldn’t of worked with any one more professional, honest and talented.

Wonderful people to work with. Family owned and operated. Vitaliy came to us the very same day I contacted them. This is rare if you are familiar with how contractors work. You’re lucky if they even call you back. Very professional, respectful, and prompt with their responses to my inquiry and concerns. Project was completed within the quoted time frame. Outstanding service and workmanship. I highly recommend them and will certainly use them again. A+++ for Knock on Glass.

I found this company on Unilocal.The reviews were excellent and with that information I went with them. THEY WERE FABULOUS. The customer service, the work performed, the quality of materials, the timeframe, the installation process were excellent and I would recommend this company without any hesitation. I love my new shower door.

Vitaliy was awesome. I called several places to get estimates for a glass tabletop. He offered competitive prices and was willing to work with me. He called back when he said he would call back. He came to give me an estimate when he said would come. Follow through is key, customer service is key. Knock on Glass has both. Vitaliy was willing to work around the delivery schedule of the wood table I ordered. I really appreciated that. Unfortunately the wood came damaged. He was gracious enough to hold onto my finished glass tabletop — which he made for me very quickly, and offered to try to make it fit for the new wood table I have to buy. I am so thankful and appreciative of this stellar customer service. The damaged wood table is not even their problem, yet, they are helping me. I have already recommended this company to friends. I would definitely use them again. Thank you, Vitaliy!

My custom glass shower door suddenly shattered while I was out of the country on vacation for the holidays. While away, I found Knock on Glass on Unilocal,I took a chance and it paid off — they came the day after my return, measured gave me a better than expected estimate and a week later — my shower doors are intact. The BEST service!

My experience with these guys is top notch. Definitely one of the easier companies to deal with in the neighborhood. I contacted Vitaliy after I looked over his website. We talked for a bit regarding my window installation. He got my order in after some questions and some measurements. He called next day to confirm an appointment for installation and that was it. The guys came, installed and cleaned up. I am impressed and will use again if the need arises. He called back to make sure I was satisfied and at the same time I ordered a mirror from him. They will be coming to install that as well.

I’ve worked with Vitaliy multiple times now and have experienced nothing but the best service. From conception to completion, he provided excellent customer service and exceptional work, especially with custom projects. I look forward to using Knock on Glass again in the future!

Professional team, promptly and timely showed to my home for an estimate.
Extremely knowledgeable. Job was done in little more than a week and was done
with extreme care and diligence.
