"This is the second bathroom that I’ve had Miguel and his team come out to install the glass shower door. They were very professional throughout the process and the price was very reasonable. Great service just like they were with my first bathroom project 7 years ago! Thanks for the great work. Highly recommend Installers DMV"

"I am very happy with the work performed by Advanced Glass. We solicited multiple bids, they were the lowest cost. Also, they were very helpful with design ideas (what works and does not). Install was on time (3 hours); very nice work. Cleanup and low noise. Excellent! Now we have a very fancy glass shower. Wife is very pleased and we saved several hundred dollars over other other bud prices."

"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 from Boston Windows was exceedingly professional and up front. I called him for a quote to replace the windows in my townhouse. He was able to come to my house the next day to take measurements. He has been doing installations since he was 16 and had alot of knowledge. Prior to the visit, he had me send some photos of my windows to try to gage the price of the job better as well. Long story short, Mr. Boston tried to price match one of my quotes for me, but there ended up being a problem with the way my windows were cut in the townhouse on the outside, which would have increased the cost of the job by several hundred dollars because he has to pay staff to do it (vs. the other company, whose labor is all in-house). In other words, he couldn't match the price after all because I was already offered a discount from the other company and the job was so complicated. The other window companies would not have paid attention to the level of detail Mr. Boston had specified, but I ended up making my decision due to budget reasons. Mr. Boston even went and looked at my neighbor's windows to compare the architecture (since town houses are supposed to be built the same). Mr. William did not pressure me in a sale like some other companies and was up front about the cost and what I was going getting myself into if I went with X, Y, or Z. He told me flat out, that if the other similar company could keep everything in-house and could cut me a really good deal, I should go with them. Because of that, I really appreciate it. I would recommend giving BWD windows a chance if you are on the market for windows; he will try his best to work with the prices, being a one-man shop. If you have a really complicated job that would significantly affect the functioning of your house however, I would also recommend having his expertise on the job. I will be calling him if I ever need a repair on a window or door down the line."

"I purchased 8 glass shelves from River Glass. I first contacted them via email to get an estimate and then placed the order via email. The entire experience was great, though there were a few logistical issues with getting the shelves delivered. Approximately two weeks after my order an employee called me and said they were ready and would like to deliver them today. Him and I worked out a time in the afternoon that would work for me so that I could be home to receive the shelves. Midmorning the delivery driver called me and said that he was on the way to my house to deliver the shelves and that he would be there in 20 minutes. I told him that another employee and I agreed that the shelves would be delivered in the afternoon when I would be home. The delivery drive at first was not ok with this arrangement and said that he was in the area and needed to deliver these now and that if I wasn't home he could just leave them on my door step. I was not comfortable with this arrangement because they were expensive pieces of glass and they were very fragile. He told me that he would have to call his supervisor and he would call me back. After waiting a couple of hours without hearing from the driver I went home for the originally scheduled delivery and the shelves were delivered at the tail end to slightly after the delivery window. This caused a minor headache on delivery day but other then that I had a great experience with River Glass and the quality of the shelves is awesome. Their price was much better than any other estimate I received."

Glass Block Windows questions, answered by experts

Their thickness depends on application, but most glass walls are typically 3/8 to 3/4 of an inch thick. Although it’s not as common, single panes of glass can also be 1 inch thick.

Glass block windows typically last for 15 to 30 years, which is slightly less than the 20- to 50-year lifespan of standard windows. You can extend their life by resealing them every few years. Professional installation is also key to ensuring the windows are placed correctly and will function properly for years to come. A professional installer will have the necessary skills, tools, and knowledge to install these features and can identify potential issues like damaged frames or cramped areas during a consultation.

Yes, many professionals provide custom-cut glass replacements for enclosures that require precise sizing.

Glass block windows aren’t fire hazards; fire-rated glass block windows can increase your home’s fire safety. Modern glass blocks are made with materials that can resist high temperatures and prevent fire spread. Most offer a 45-minute fire rating, while some increase it to two hours. Compared to the typical 20 to 90 minute rating for a double-pane window, glass block can increase your home’s safety in the event of a fire.

Luckily, glass block windows need minimal maintenance. Other than regular cleaning, the only maintenance involved in having a glass block window is inspecting for cracks every year and applying sealer to the mortar joints if the blocks are set in masonry mortar. Glass block windows hold up well against wind and moisture better than traditional windows and are not prone to rot.
