"A. R. Glass did a fantastic job. Instead of having to replace my windows, they were able to come in and replace the glass for considerable savings. I would definitely have them come again. In fact, I had them come for a second job already."

"I called Advanced glass on monday the 7th for a quote for my newly remodeled bathroom. I spoo to Sam over the phone and he gave me a quote how  much approximately it'd cost. The price was reasonable so I requested an appointment to do the measurment. after that Youness came over the next day he took the measurment and gave me the final estimate of $1175, I approved the quote and payed the deposit right away. On the 17th the installers (i guess one of them was albert) came to my house and install the glass shower door in about one hour and a half, and they told me to not use the shower for 24h. Now i'm using the enclosure and it's fine with no issues. the only thing is when i open the door, the water drops from the door, but i guess that has nothing to do with the job they did.

"oThis was a great experience start to finish. The price is solid, beating out my insurance company's provider by a good $80 - $100, the work was scheduled and performed quickly and the windshield looks good.
I used the $25 off coupon I printed  from Angies list without a problem, which brought the cost from 255 down to 230.
My insurance company's placed wanted $298 plus tax plus $29.95 to come out
to me to fix it. Royal did all that for the flat $255.
Definitely would use them again if I needed to replace any of my car's glass.

"William was great to work with! After my neighbor boarded the door for me, I called him about 9:00 p.m. and he came out the next morning to assess the situation. Since my door was so old I decided to go with a new sliding glass door. He had to order the door which took a few days. He sent a tech out to replace the door and Jimmy did a wonderful job installing it. There were such a pleasure to work with and it made the stress of the break in a little easier to deal with."

Glass Block Windows FAQs, answered by experts

Yes, professionals can install decorative or colored glass block patterns for a unique look.

Glass block mortar is the best choice for glass block window units. It is specifically formulated for glass block window installation. Glass block mortar is usually a mixture of Portland cement, sand, and special chemicals. It is a white mortar that is applicable inside and outside your home. Do not use regular tile mortar because it may not have the binding strength and flexibility required for glass block windows.

Options include tempered, laminated, and tinted glass for various needs.

New glass costs anywhere from $3 to $100 per square foot. More specifically, tempered and insulated glass—a common option for sliding glass doors—costs between $10 and $14 per square foot.

Most installations take 1-3 days, depending on the number of blocks and customization requirements.
