I am extremely pleased with the preparatory work, the installation, and the follow-up. The staff members through the entire process were professional, attentive and there when they promised to be there. I definitely recommend WMGB!
I have only the highest compliments for the team of installers who reinsulated our attic. Not only were they extremely cordial throughout their stay but absolutely fulfilled all our expectations. This is the second time we've employed this firm and have been impressed both times with the quality of their work.…
WMGB installed two glass block windows for us. We are very happy with the results. WMGB was professional, effecient and courteous from start to finish.
My experience was amazing from start to finish! WMGB is a first-class company!
My technician (Trevor?) was very helpful and courteous even though it was a dusty job replacing windows in the basement of an older house.
Derek was a thoughtful and very personable sales representative. Scott with installation was detail oriented, thorough and also real friendly. WMGB was easy to work with and did a great job replacing our basement windows. The additional light from the egress window and the glass block windows was amazing. We are very happy with the results.
The service was great. Arrived early & had all 4 glass block windows installed before noon.
Everything from the quote to the install to the help with questions/concerns was great.
They were fabulous, on time and super clean up on afterwards
Harper did a fantastic job and was a pleasure to work with.
The four stars was achieved primarily because the installer knew what he was doing and handled the situation professionally. Most of the experience leading up to it was more of a three star experience. They missed the time window on both of the measurement visits. They also had to reschedule the install date with…
Danny and Tra were awesome! Helped with any questions we had and were very personable. Super satisfied with the work they did.
Our installers, Anthony and Trevor, were outstanding! They did a beautiful job and were so nice and efficient. They also were careful of our house and made sure we were satisfied with the result. Great job!
Excellent service. On time, professional and knowledgeable. Highly recommended!
WMGB has been phenomenal to work with. They were timely, efficient, and thorough.
Danny was great . Very professional. I would recommend him highly and hire him again. He does great work.
Exception service! Love the windows and they cleaned up nicely.
Had a glass block window put in my basement crawl space. They did a great job and they were quick and efficient. Would have them out anytime.
had WMGB replace a glass block window that they installed over 30 years ago during a resent walk in shower up grade. Scott our installer and the sales crew were great the Mrs is very happy with it .
Had an Egress window installed in January. The process of the installation was bad enough with them only finishing up when it was convenient weeks after the main installation but… Just last week had an irrigation company come out to get our sprinklers maintained and positioned correctly. Come to find out WMGB ripped…
We discovered this company while visiting relatives in Ohio. Since our initial contact to replace two sets of French Doors, the entire process has been exceptional, simple, and the products are of the highest quality (while not the priciest in the market!) No hesitation to recommend this company to anyone.
Great company to work with and fantastic work, would highly recommend!
WMGB did a great job overall. The final result is a beautiful faux block window that gives the house a very elevated look. There was a little hiccup at first, but it was resolved by Emily in the most professional way. The installer, Thomas, also did a fantastic job with the installation. In the end, it turned out exactly how I imagined it would look.
We had our screen door and front door replaced. Competitive pricing and very much appreciated the no pressure quote. LOVE how the door turned out and it makes such a huge difference on the light inside. At install noticed some slight manufacturer damage and it was immediately taken care of. We have gotten…
We’ve used WMGB for a few projects now. They are always incredibly professional throughout the installation process. The glass blocks that were installed have helped reduce heating & cooling bills while letting in so much more natural light. We couldn’t be happier. Highly recommend!
Hello, I had a great experience with W.M.G.B. on April 6th 2026 Kaden called me about 15 minutes before they arrived at 9 a. m. When they got here, Kaden and Dan introduced themselves, and promptly went to work. They installed my 6 basement glass block vented windows. In addition to cleaning up, and removing all…
WMGB did a great job on quote, quickness and quality. I highly recommend them. I.had a small follow up issue, and they came right out and handled it-perfectly. They’re now put in 3 egress windows for us.
Excellent service and customer experience
2 big thumbs-up for WMGB, and especially our install crew of Thomas and Dan. Both guys were top-notch. Friendly, professional, worked with a sense of urgency - but not rushed. They replaced 6 basement windows with glass block and the results are fantastic. Would definitely recommend WMGB.
Great experience from start to finish. Gave me a great price right a the start no pressure sales pitch, two weeks later they installed seven glass block windows in my basement in three hours.
Great company! Customer service was superb. They were patient as I was deciding how many windows would be cut into the basement. I should have done this years ago - it's so much nicer now that I can see outside!
Had basement windows installed. Very professional job.Installer did a great job and cleaned up the area when he finished.
Everything went smooth, but the whole process took forever. We put the deposit down in November and it took until the end of March before the windows were installed. It felt like an extremely long time for 2 windows.
WMGB transformed the look of my home by installing four new glass block windows. The team (led by Scott) was nothing short of outstanding! They were polite, professional and respectful during the entire installation process. Great job and a heartfelt thank you.
Technician was on time, polite and got the job done quickly and efficiently. The gentleman that came and completed the estimate was also great.
WMGB staff were great to work with. They accommodated our schedule and followed through with any questions or concerns. We used them to replace basement windows in our home with custom fitted glass block. We are pleased with how they turned out and would highly recommend WMGB.
One star is TOO generous for this company. We ordered a new storm door and screen door from them, storm door was supposed to be Robins Egg Blue and I got a Teal door. Screen door has been an issue from day one, it’s falling apart, screen in the bottom half comes out all the time and the door doesn’t latch properly.…
Each and every employee I spoke with/did the work were wonderful. They were prompt, courteous and timely in all work. Work is always done with respect for property, and careful installation. I highly recommend them.
Last spring, I received a quote from WMGB to replace a few basement windows. They were running a special promotion at the time but I wasn’t quite ready to move forward. This past January, I reached back out to Derek; who I had worked with previously, and they were able to honor my original quote. Derek was…
The team did an amazing good! Clean timely Great experience!
