Our Customer Reviews
Waleska was very good! She quickly got the window site cleaned up and then built a frame for a double plywood board cover for the window. It looks good and is secure.
Great service and communication. The technicians were both polite and did a great job fixing our glass pane on our front door. Looks amazing!!
It was great doing business with Reza. You can call at anytime with questions and he answers, no voicemail. I had an entire window crack due to heat from our misplaced grill. He offered to replace the window type as is or I can opt for a sturdier tempered glass. I chose the tempered. His quote was competitive, no hidden fees; he showed up exactly on time, finished within 2 hours, and cleaned up after himself.
Replacing window glass was a breeze, on time very quick and efficient. Pleasant demeanor from installer. Window looks like new. Thank you great job.
We had a great experience with Glassma! They had reasonable rates and were able to work around our busy office. They even had a crew come in on their day off to meet our needs and service the office. Most of our conference room window gaskets had been failing or weren’t properly installed and that’s what they came to remedy. All work looks great! The staff was also very friendly and easy to work with. Even their coordinator was very friendly and kept us up to date.
I’d like to give a high rating for the fast and efficient delivery. The delivery team was very friendly, and overall I’m extremely satisfied. Highly recommended!
We had our front door and glass replaced by Reza, Teodoro, and Waleska.They were professional, finished on schedule, and provided great quality at a fair price. Highly recommended!
They were very prompt, fast, and thorough! Will definitely use them again when the knee arises!
Friendly , fast and efficient. I would recommend to anyone .
