"I am very fussy and frequently critical, yet I have only the best things to say about Unicorp window replacement. The owner came to my home - on time - to explain all the options and costs for replacing my windows. It didn't feel like a sales pitch, but more like a discussion of what was best for my home. Unicorp is a local company and makes their own windows, so I knew if there was a problem, there would be someone nearby to call. My windows were installed on time and the crew was very professional. They are very hard workers; they didn't even take a lunch break. I was assured that my new windows would not let the cold air in, as my old windows did. I'll have to wait for winter to test this out, but I have confidence that since these windows were custom-made for me, they fit more tightly. It has been a pleasure to find a local company that has an excellent product, is honest, and reasonably priced."

"This is the second time that we hired Zen Windows for a project, and we could not be more pleased with the service, professionalism and the results on both occasions. They are very responsive, helped us identify the right products and made the entire process as stress-free as possible. Replacing windows and doors is a big project, and having a company you can trust will do it right makes all the difference. Scott and his team are great to work with!"

"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 hired them to replace approximately 32 double hung windows. the price was as good as any and i was in no mood to haggle. the process was very clearly spelled out and the prep that i would have to do was, as well. there were a few snags with them getting the windows (due to supply chain issues that everyone was having) so the dates changed, but i was involved in those changes. when they did start, they got most of the work done on the first day and came back to finish the next day. a few things went wrong, a window was broken, another had a scratch, and many of the windows were over-caulked to the point of being awful looking. the broken window was addressed even before i brought it up, as was the crack. when i told them about the caulking they sent someone the very next day and told me the installation crew had used the wrong caulk (outside caulk) and that they would be back to fix it. they did.... there were a few more windows after that i saw too much caulking on, and they've come out to redo those, too. All in all, their service is amazing. there were so many people involved who deserve a shout out, but i can't recall their names. my team leader or manager was Michael and he was a gem. i wouldn't say the product i bought is the best; the corners aren't perfect and the glass fogs up (i'll let Presidential know when i have a minute), but the windows work great and they look exactly like what i wanted. i was so thrilled with them, that i ordered a replacement for my front door with sidelights and transom! the price was comparable and i already knew what kind of service i was going to get. And i did!"

"Everything went great. They came out a measured my windows. About 3 weeks later, I had 5 custom windows installed. The installers were on time, very neat and look like they did a good job installing the windows. Around the outside, the windows were capped and afterwards they showed me how to open and clean them. I will be calling them up once I save up for my other windows."

"The Premier Windows and Glass has provided an excellent service for me! A frame of one of the windows in my condo was broken, and I looked for a company that would fix it and prolong the life of the window. So, I was very happy to discover The Premier Windows and Glass. Their technician was very polite, professional, and knowledgeable. Not only did he do a quality job on fixing the frame, but he also explained to me what needs to be done to prevent the window from breaking down again and avoid paying a lot of money for its replacement. In addition, the manager and technician responded to my service request in a prompt manner. The problem was solved on the day when I called the company. Last but not least, the company offers competitive service rates and does not push people to spend more money than is absolutely necessary. I would strongly recommend this company to anyone who needs a window to be fixed or replaced."

Glaziers FAQs, answered by experts

There is no blanket number when it comes to glass thickness for soundproofing. Thicker glass does help reduce noise, but it’s only part of the solution. Most single-pane windows use glass that’s ⅛” to ¼” thick. While increasing the thickness can cut down on sound, the real noise-blocking power comes from stacking layers. Double—and triple-pane windows are far more effective for soundproofing. The combination of mass and separation breaks up sound waves better than thick glass could on its own.

Prior to the middle part of the 1900s, glass manufacturers used a technique that involved blowing glass into cylinder shapes that were then flattened out to create sheets used for windows and doors. This technique often left behind ripples and inconsistencies in the glass.

You can purchase standard mirrors up to 98 by 80 inches or larger custom mirrors. However, larger mirrors often need to comprise more than one piece of glass.

Replacing a glass pane is much less expensive than replacing your entire window. The average person will pay between $180 and $400 to replace a glass window pane. This price can vary based on a ton of factors, including labor costs in your area, special window treatments, and the number of panes on your window. 

Distilled white vinegar removes stickers from glass by breaking down the adhesive with its acidic qualities. You can apply the vinegar to the area with a sponge or cleaning cloth. Let it sit for 10 to 20 minutes, and then scrape the area with a plastic scraper or the edge of a credit card.
