"I can't recommend this company/Attila enough. I was moving to a newly purchased house where the previous owners broke a window in the garage (and didn't fix it). I needed to have the window fixed in the sliver of time between when I took possession of the house and when I moved in -- and our closing got delayed. Attila was so calm (I was very stressed out) and accommodating. Yes, it was a simple job but it was an important one that was done well and with minimal added stress to me. After I moved in I asked for ideas about how to add screen doors to the french doors because I have indoor only cats that I didn't want to get out. He had some great ideas (and ones which were most cost effective than mine), promptly ordered and installed the screen doors (with special pet screening). When it comes time to replace my living room windows I will be giving him a call because not only does he do quality work, he is very professional and a very nice guy."

The work performed was difficult and the team was absolutely careful of our house when the windows were replaced. I heartily recommend them for quality, honesty, and definitely value for service and parts; 5 stars for sure!. If you choose them, you won't go wrong!"

"Very well.  I was unsure what I needed to really look at buy.  Shawn was very helpful and patient.  He provided me with glass options and the benefits of each.  His recommendation ended up being less expensive than what I was originally going with.  I would definitely recommend this company and plan to use them again soon. I'm very happy with the glass shower, it really completes the look of my master bathroom!"

Glass Block Windows FAQs, answered by experts

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

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

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.

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. 

Heavy glass tends to be more expensive than thin glass because it is stronger and more durable. In most cases, ¼-inch-thick glass is ideal for mirrors, and ⅛-inch-thick glass is ideal for residential windows. Heavier glass isn’t always necessary, and can be more challenging to hang or install. Work with a local window installation pro for replacement or new construction windows.
