"I had a fantastic experience with Fernando's company, Best Glass, LLC. Both Fernando and his wife were incredibly polite and efficient. Arriving on time installed my bathroom shower glass door in under two hours, and the end result is absolutely stunning. Fernando's attention to detail was incredible I appreciate their thoroughness and professionalism not to mention FAIR rates … Best Glass, LLC. Highly recommended!"

"They installed some mirrors in my home and it was amazing. They were fast, efficient and polite. They explained the process step-by-step and showed me the material they were using before hand. They scheduled their appointment promptly after calling and arrived 15 minutes before arriving. The quote was free."

"Somehow, in the line of communication, the separate estimate (including description of window to be cut/installed) did not manifest. A call to Frank Cortes of Castle in Bristol, rectified that and the cost of the additional window was quoted which seemed rather high), and when I verbalized that, it was adjusted downward to a cost that seemed fair and we moved forward. I was told by Castle that they would handle the approval of my window installation with Imagineers, the condo management company. This turned out not to be the case. I had to personally oversee this. Initially, there was a considerable amount of phone calling and emailing that took place to get everyone 'on the same page' relevant to the building permit and the architectural drawing of the new window. Never having owned a condo before, it was a huge learning process for me. There were many twists and turns and at times I was ready to throw in the proverbial towel; but, thanks to the intervention of a wonderful consultant here in Glastonbury who stepped in and took over the reins at the last moment, the proper/necessary information on the actual construction of the new window was accomplished, the building permit achieved, approval from the management company and the condo association board was granted, and a date was set for the install. On the day of the install, a crew of three men arrived. They were extremely well trained, courteous, and respectful of my home. Protective coverings were laid down wherever they were working. They were an impressive team who chattered easily amongst themselves and the install was seamless. The lead installer, Victor, answered any questions I had and made me feel very comfortable that all would go well. His workmanship was impeccable. The cutting into the wall in the bedroom was done with complete attention to detail and the finished product was perfection! It was a long day but worth every single minute. When they were finished, the yard surrounding my condo was strewn with debris that completely disappeared before they departed. I can honestly say that from start to finish, the window installers were nothing less than completely professional. My dealings with Mike at (headquarters?) in New Jersey were always addressed promptly and professionally. There may have been one or two minor glitches, but were more to do with communication and were always resolved. In summary: I have only great things to say about Castle Windows. Do I think I may have spent less with another company? Possibly. But, in hindsight, I do not regret my choice, and I would highly recommend: the company, the employees.....and the product! Class A quality all the way around."

"I'd like to give 15 stars. Stop searching for a stained glass studio. HIRE TERRAZA NOW. I had what I thought was a simple stained glass project, and I knew exactly what I wanted. After contacting a dozen studios, I found that Terraza was the most willing to take a shot at the project, and it offered the best price by far. Donna sat with me, brainstormed and shared her expertise. What I came away with wasn't a thing like I thought I wanted, and yet it was PERFECT. The project wasn't simple. It required engineering outside-the-box for a stained glass studio, and with Donna's eager, enthusiastic advice and involvement, the project was a total success. Along the way, there was a glitch, but Terraza handled it with aplomb. In fact, when the project was delivered personally by Terraza, we were told that unless we liked it, it was going back. Donna was unhappier than she thought we might be with the way something played out, and she practically demanded the opportunity to improve it. All was made right, and now, every time I enter my living room where the project resides, a get a happy feeling about it and my dealings with Terraza. I have another stained glass project at hand, and a simple, quick note to Donna brought Terraza right on board."

"Made an appt. with Castle Rep, James, for 17 windows and vinyl siding. He spent 1 hour talking about how great his company and windows are before finally getting down to the issue. We were told that CASTLE makes and services their own window, with all the best technology and technicians available. The price per window for energy efficient came out to over $1,200 per double-hung window! And since they make their own products, we could not find a way to compare quality and price with other manufacturers. But his per-window price exceeds the average price of $500-700 by A LOT! When we balked, he made a call to his "manager" to see if we qualified for a "special promotional" discount. If we were to commit right there on the spot, we would get an additional 10% off! Still way to high. We said we would think about it (he got sad and snippy), and that we wanted to hear about the vinyl siding quote before we made any decisions. He told us he could not give us a siding quote until his company did an "eagle view" measurement, which would require another appointment! We had no intention of sitting through ANOTHER high-pressure appointment. High pressure, long-drawn out presentation and he would not leave us with anything in writing! No brochures, prices, nothing! He refused to put anything in writing and we could not have a break down of labor and costs. I even asked him if I could have a copyhh of the window warranty and he said "only if you purchase right now." And they did not come prepared with references or previous job locations! When we further researched the company, we found they did make very excellent products, but the #1 complaint was by far that they did not honor their lifetime warranty and that customer service was horrible. In the end, we chose not to do business.."

"they were very good at what they did, the older man knew his stuff and was very polite and a younger son also knew what he was talking about and also was very nice. The wife behind the desk was very polite and funny and good to talk to, I would absolutely do work with this business again top notch company. Don't let the size of them scare you away, even though they are small I will use them over any big glass company around hands down. They are clearly is the best in my opinion"

"For starters, John replied to my messages within an hour throughout our interactions, and there were quite a few more than normal due to my mistake. He was so responsive that I got to checking for a reply within 10 minutes of sending it and there it was! Some of the other 4-5 handymen I reached out to replied after a day and some didn’t at all. Anyway he came the first time and we screwed up so he had wasted his time for this visit as we gave a wrong phone number and didn’t hear the doorbell. John was completely understanding and we re-scheduled for the next day! He took care of the job without any problem and was actually pleasant to have over as our guest during the time! He’s a very understanding, patient, kind and competent guy. So thankful!"

Glass Block Windows questions, answered by experts

Glass block windows come in various patterns and styles that offer privacy and unique aesthetics. Frosted or textured glass diffuses light and enhances privacy. Wave-pattern glass blocks imitate ocean waves with flowing lines. Ice-glass blocks resemble cracked ice. Fluted glass blocks feature parallel vertical grooves, adding texture and depth. Clear glass blocks, similar to glass Coke bottles, offer transparency with some distortion and may have smooth surfaces or subtle textures, adding visual interest.

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.

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.

Glass block installation can be relatively expensive due to the range of material costs and the labor time to assemble this type of specialty window. The process proceeds slowly as the glass does not absorb moisture from mortar and silicone caulk takes longer to harden, leaving spacers to hold up the structure until the caulk or mortar begins to cure. Plus, if your current windows have structural issues or damage, you’ll need to repair them before beginning the project, increasing your bottom line. 

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
