Kristen F.Home Owner
Vitaliy is just phenomenal. His response time is prompt & professional. I hired him to install a shower door in a new apartment that I purchased. Installation time was approximately 1.5 hours. I contacted another company and still have not heard back from them. In that time frame, Vitaliy measured the shower dimensions and installed the door. It was such a seamless process. Thank you.
Colby G.Home Owner
They are absolutely the best! Responsive, professional and wonderful all around. Couldn’t recommend them more and their work is beautiful.
Adam S.Home Owner
I needed a glass shower door added and these guys did a *great* job – explained my options and made quick good work at a fair price, with attention to a bunch of little details and aesthetics. see photos.
Rivky B.Home Owner
Great job with my shower doors! Service and communication from start to finish was professional, friendly and efficient. Cost was similar to other quotes I received so they are priced fairly. In comparison with other companies I spoke to, they had the best response time and most personalized service, from the owner himself.

Vitaliy just finished a job for my renovation project involving measurement of our shower, custom fabrication of low-iron glass doors, and installation of double-bypass frameless Cambridge system hardware. The outcome far exceeded my expectations. The shower doors were just an afterthought for me going into this, but they ended up serving as the centerpiece for our beautiful new bathroom. I had not anticipated the value that they would bring to this space. This made an otherwise nice bathroom into a dazzling one.

I called Vitaliy a few years ago, based on Yelp reviews, for a glass shower enclosure in my new apartment. Service, quality, and workmanship were amazing. So wonderful, that when I return from Morocco with a cocktail table in need of a glass top, I got in touch with Vitaliy again. Again, amazing all around! Neither project was cookie cutter; The shower enclosure is in an irregular, pre-war building. The glass table top is for an antique Berber door, made into a table. Measurements were difficult, but everything is perfect. Highly recommend!
