"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."

"Glass Impressions did a wonderful job of cleaning all 19 windows in our home, inside & out, including the inside sills, screens and also 2 glass storm doors. Mr. Waters and his team are very good at what they do. They were very reasonable. I plan to use them again, as needed."

"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."

Glass Block Windows FAQs, 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.

Regular cleaning with non-abrasive cleaners helps prevent buildup and maintains clarity.

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.

Installing glass block windows has benefits and disadvantages, as with most materials. The pros and cons can vary depending on the type of glass block and the window location.

Pros

  • Maintains privacy while letting light into the bathroom

  • Energy efficient

  • Sealed to prevent drafts

  • Aesthetically pleasing

  • Strong and secure

Cons

  • Costly to install

  • Challenging installation

  • Challenging repair

You can still see vaguely into some types of glass block windows at night. Although there won’t be clear definitions, passersby may still see shapes, shadows, and movement through the glass. If you want complete privacy, consider installing diamond glass block windows rather than the typical clear or wavy glass blocks.
