I can attest and verify that Maryland Glass Block is out of business and court records show that a principal of this business is scamming potential customers out of their money. I ordered windows to pick-up and was even sent a contract/order form and reluctantly paid for them with zelle, the person has now ghosted me and I am out of $700. The business is no longer there. BEWARE!!! read more

On September 22 2025, my mother and I had these guys do 7 windows for us and its been a nightmare trying to get them to straighten it out. 5 out of 7 windows are installed misaligned, meaning they literally are not centered in any shape, form or fashion to the foundation wall. This is both visible from outside and especially inside. You can clearly/easily see how one side of each window will be all the way in and one side will be all the way out. 3 windows have damage to the vent screens with 1 of those vent screens actually having a tear in the screen where the corner of a another glass block window actually scratched the vent glass itself. How do I know this? I watched them unload all 7 windows out of the back of a Buick towncar where they couldn't even be bothered to put something in-between each window to help avoid accidental transportation damage. Also one window has chipped glass on the exterior of the window. 6 out of 7 windows have visible product barcodes that you can see in every angle that you look at the windows which is ludicrous that they thought that was acceptable to the customer. Their installers installed damaged windows that they had to have seen/known at the time and just didn't care. Their installers also left me a slop mess under the 1 bathroom wall window with mortar all over the place. My mother and I have called, emailed and I have went to their place of business which was unbelievably closed around noon on a Friday. The owner stated in a email on October 19th that they would make it right which still hasn't happened as of November 2 2025. We would have never used this company had we would have known that we were going to have damaged windows, crooked installations and a plethora of lovely barcodes to look at forever. To add insult to injury it sucks being told your right that they need to make it right and nothing ever happening as a result of it. I have tried to avoid filing a mhic claim but I have to at this stage as they are avoiding both my mother and I at all costs. I would like to make a point in stating that I have not called repeatedly every day all day, I have given a bare minimum of 4 to 5 days at a time to get a response and that just hasn't happened. We want them to either remanufactor every window or refund us as we didn't pay 2802.00 for this kind of sloppy work. I hope this helps someone else as what they did to us is unacceptable and they are doing nothing about it besides dragging it out further with no resolution. When you see this Mr. Scott Fava, I've been incredibly patient, please call one of us and either cut a check and refund us or remanufactor these windows and make it right. Update 11/10/25, we dug into Mr. Fava hard and found he lost his MHIC license in Februrary 2025, he has a 213,000 dollar IRS judgement against him, he has new and prior claims against him and it would seem he hasn't paid any of his debts in a long time. Do Not Under Any Circumstances give this jackass any of your money, time or consideration for his work as he isn't licensed and is literally out here robbing peter to pay paul as we are fairly certain he did this shit to us just as a quick money grab to pay down his judgements against him. Absolutely ridiculous, we did a pretty good overall look at Maryland Glass Block before we did business with them and wish we would have looked into Mr. Fava personally a lot harder. He robbed us of over 2800 with his silicone constructed, misaligned and barcode laden windows all while promising us he would make it right. His failure to make it right for us is going to result in another lawsuit as he committed a fraudulent act against us personally by operationing under the guise of being a legitimate business when he was no longer licensed. I will update this as the matter proceeds. We have already started the process. read more

They did an incredible job and came all the way to Gaithersburg from Baltimore. Highly recommended! The pictures I added speak for themselves. My windows were the boarded, broken down busted up junk and then the after job, by Maryland Glass Block. The crew was fast, friendly and the price was VERY affordable and this company is AWESOME! read more

The windows in my basement were awful. They looked to be original to the 1952 house. The wooden frames were dry-rotted, the glass single paned, and the storm windows stopped half an inch short of the edge. Two of them were also broken in some fashion, but just not worth repairing. The man who came to do the estimate was straight-forward, knowledgeable, nice, and not pushy. We chose "wavy" glass block. One thing I didn't know to ask at the time was what the R-factor of various choices was and whether one type was more secure than another. The wavy just looked best and offered a degree of privacy. FYI: Maryland Glass Block is the only glass block place around that sells custom-sized glass block windows you can install yourself ($99/window if you install them yourself). Home Depot sells one size of pre-made glass block windows for $99. No reason to go with Home Depot over Maryland Glass Block. Personally, I decided against installing them myself because one of my goals was to stop some leaking (air and water). As I didn't have a strong understanding of how to install glass block windows, PLUS I knew those suckers would be heavy, I didn't think I should chance it. (After watching two experienced men working together to level my windows, I knew I'd made the right choice.) I got an estimate and then waited a whole year to decide to go ahead with the job. (I have been doing a lot of work on my house, so I had to get things done in the right order.) Maryland Glass Block stuck by their original estimate with no problem. The installers were lovely. I had ordered two windows with vents and two without. Before cementing the windows in, one installer thought to double check with me if I really wanted a vented window in the laundry room. I said no. Then AFTER he had switched them (but before he had cemented them), I realized that the order was correct--I had indeed wanted the vented window in the laundry room. I felt so bad that I gave them a $30 or $40 tip. But they didn't know that was coming and they were still so nice. They did a great job, too. They leveled the windows much better than I would have been able to do, cemented everything in cleanly, and took away all the mess of the old windows. I'm glad I decided to put the vents in hidden places. They're not the prettiest things. Honestly, I think the vents look a bit trashy if put in a living area. The pure glass block is kind of nice. Having a vent in the laundry room is helpful, though. And I like the idea of having another vent on the other side of the basement, should I need to air things out. It's been 6 months since they were installed, and the basement has been dry ever since. I also feel confident that this company would take care of things should something go wrong. read more
