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!
We had 3 glass block windows installed in our basement. The estimate and quote was an easy process. Dan installed each window with care to make sure each unit was a good fit and did an excellent job cleaning up the area after he was done. I appreciated being able to look over the project and ask questions before he left our home.
Exceptional customer service and professionalism! Dan was quick and efficient putting in our new glass block windows for our basement. I would recommend them for anyone who needs a home improvement!
Recently had a Glass Block window installed from WMGB. Absolutely beautiful job! Derek Worley came out, took some measurements, gave me a quote, and in 3 weeks the glass block window was installed. Derek was professional, not condescending in the least, and answered all of my questions. He is a no pressure…
Left unfinished on the inside. What was told in the beginning was not the results. I was told to get a "handy man". The old wood was left around the windows, some nails left that me and family pulled the rest out. Holes left in bottom of the windows where you see dirt at the bottom. I Had to get another company out…
Very customer service oriented. Matt Trumbell's follow up was good.
Fantastic experience with WMGB! From the moment I reached out for a quote, they had excellent communication. Sales Rep was great, personable, and honest about his recommendations for my property. We did have to reschedule my install - but the installer was super considerate, helpful above and beyond, and did a great job. 10/10 recommend
I had a great experience with WMGB. They were prompt with their quote and once I made a decision the turnaround to install was pretty quick. Tom did a great job with the glass block install (and making sense of my old house) and everything was so tidy when he was done! Shout out to Sha’von for her friendly and…
We had a great experience. Dan did a wonderful job. I would highly recommend him.
Professional, quality service. We wanted a new decorative entry way door and the staff was patient and thorough during the selection process. Installers were great. Would absolutely use them again.
Mike and the entire WMGB team was nice to work with. The job went as expected and turned out nice!
Quote was easy to get. Installer called to let me know he was on his way. Did a very nice job and very friendly
Derek, a sales consultant at WMGB, was super responsive, informative, and ready to help us determine the best fit for our grantee. The whole team was great: they installed the windows the date they said they would, the installation was fast and smooth, and the operations side went above and beyond to help us meet…
Derek and the team are wonderful. He went over all the windows & sliding door process. The installer, John and Anthony were great at what they do. They were fast, accurate, concise, and beautiful workmanship. I absolutely love my windows. They make such a difference. I would highly recommend this company.
Derek Worley did an amazing job installing both of our glass block basement windows. I’ve had three done so far and most likely we’ll get the rest done in the future. Each one added great light to our basement and sealed the old leaky windows that were there for many years. Great job great value. Thank you, Robert.
Great company to work with. Professional staff and the installer Tom did an excellent install. After the install couldn't even tell they were there. Fair pricing and Great service!
We reached out to WMGB when we needed our basement windows replaced. They were quick to come out for a quote and measuring, were easy to set up a day for demo and install with, and provided service within weeks instead of months! The guys (Brent and his cat-loving apprentice Connor [if we remember correctly]) were…
Kayden was here on time and ended up finishing an hour early! He did a great job and cleaned up after himself. The windows look great, and I don’t even have to turn the laundry room light on cause the lights show through it. I should have done it sooner!
The guy that came out was very professional and did the work in a timely manner.
The team did an excellent job - they were hard working and dedicated to getting the project done right! I love my new windows - much appreciated!
The glass block window WMGB put in is so much better than the old single pane that was in our basement before. The team were pleasant and professional. I would recommend them to future jobs.
I recently had new vinyl and glass block windows installed by West Michigan Glass Block, and I couldn't be happier with the results. Keith was great to work with during the sales process and helped me choose the right windows for my home. Greg and Nate handled the vinyl window installation throughout the house, and…
Nick, Mark and Andrew all did outstanding job. They were on time and walked me through everything they were going to do. They made sure they had my approval on what they planned. They were professional and very friendly. I couldn’t be happy with the job they have done. I would highly recommend them. They have done…
Great company! Devin went the extra mile. Job well done
Friendly. Great work, installation time very satisfactory.
Sales, management, and install folks were all polite, informative, and responsive. Plus the windows look great and are a good value too.
All the staff we worked with was great. The installers, Victor & Brandon, were very efficient and did a great job of installing our glass block basement windows and left everything neat & clean.
WMGB was great to work with for our whole house window replacement. Communication from everyone (sales, scheduling, install, billing) was open and clear throughout the entire process. The quality and value of the ProVia windows is great and the install team were friendly, respectful and knowledgeable. Based on our…
Very professional, highly recommend. Punctual. Forgiving. Pricing seemed fair. This was all for glass block basement windows.
Great communication throughout the entire process since day 1 when I called to get an estimate. Very professional and personable with every person I met. They were thorough on measurements and when it came time for installation, they were on time (early actually), friendly, and proficient! Didn’t even take very long…
Very friendly staff & installers. Had 3 windows replaced that we didn’t replace 4 years ago. Price of windows was 1/2 the price we were quoted from other places. Actually, we had a hard time finding a company that would take on a small job of 3 windows. We had DJ come out, he had the job done under 3 hours! He…
Windows look great, we love them ❤️ People are very nice and helpful. Excellent service, definitely recommend!!!!
Im very happy with the job this company did in my house thank you
We had WMGB install 3 sturdy, glass block windows in our basement this week and I am very happy with the job they did.
I was very pleased with the service that I received from WMGB. Everyone was very professional.
I love my Provia full glass storm door. DJ did an excellent install. Prompt curious and professional.
This is the 2nd time we’ve used WMGB and both times we were very pleased. They recently installed a slider in our kitchen and their results are beautiful. The slider looks great and the team who did the install were quick, efficient and tidy. 5 stars.
They were professional and did a great job!
Great communication, fair pricing and a fantastic install experience! WMGB installed two egress windows for us to help kick-off our basement remodel project. Job well done! Professional staff/installers and sub-contractors.
I was very happy with my new block windows, the guys were friendly knowledgeable and worked very quickly.
I had four windows and a glass block window installed and I thought they did an excellent job.
We had a basement small window get broken back a bit ago and called WMGB about getting a price and time frame to get a block window Put in. Other company’s told me I would have to get at least 3 window’s done for them to come. This guys just laughed and said no they would come out for the one. Gave us a great price…
Mark T. came early and did a fast and great job in replacing the windows. Will use service again for future window replacements.
We had 3 glass block windows installed in our basement because our previous windows were leaking and letting critters in. WMGB Home Improvement's promotion discount when you install 3 or more windows beat all other estimates we got. The two guys that did the install were very professional and informative. They were…
The workers did the impossible. I didn't think they could do it. My crawl space is so small. They went above and beyond, did a great job 👏
Mark did an awesome job of installing the new glass block windows. Mark also explained the job in detail on what he had to do and cleaned up the job sites when the he was finished. He was very pleasant to talk to. I will definitely recommend west michigan glass block to friends and family.
Mark was the guy who came and, with a little help, put in 6 basement glass block windows. Everything went fine, he was diligent and detail-oriented. We are very happy with the results.
Did a great job
I had glass block windows installed. The quality of the windows is great and two guys who installed them were very knowledgeable and did an excellent job.
This company has been used before installing glass block windows in my home. They were very professional and did the work in a timely manner. Very satisfied.
WMGB did what their name says--glass block window installation. They did a good job at my home, not their place.
Mark and Darnell did a great job on our glass windows. We are very happy with how they look. Superior customer service. Great price.
Wonderful work by the install team (John and Kelum) who went over above to get the job done right and on time. I highly recommend WMGB and the ProVia windows. We are really happy with this install and the new look of our home. Great job fellas!
Brandon and Mark did an excellent job of installing block basement windows for us.
This company was great to work with. Brandon and Mark were very professional and cautious when they were installing the new windows. I would highly recommend this company and these two professional installers.
I had glass blocks windows installed in my basement. I got a great deal at the Home and Garden show. Customer Service is excellent.
We just had glass block windows installed in our basement. These windows were more difficult than the average to install (my opinion) due to the fact that the furnace was in front of them. The installers, Mark and Brandon, did a fantastic job despite the challenge. These two are the pros for sure! Thank you for such detailed, skilled work.
Installer was very good and quick. Windows look great
My 100 year old Michigan basement had 3 windows that were boarded up with plywood. I had them replaced with glass block and it feels like I have a new basement. Everything was great and professional. Good price, and Mark the installer worked quickly, was on time, and a pleasure to work with.
We have used WMGB for two different projects. It has been extremely difficult to work with them both times. We used them the second time because the first hire was during the pandemic and we had some grace. Here were some issues: Failure to call back and give updates on projects. Failure to finish the work that…
Andrew and Mark are amazing individuals who put the customer first and do an amazing job. I highly recommend WMGB for glass blocks if you need them and they have an amazing BOGO free deal going as well!!!
