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!
Careful, professional service! Thanks for going the extra mile.
Edit: 4 yrs later from initial review. We needed an old egress window replaced and the final glass block basement window installed. Again WMGB was excellent to work with. Danny and Harper were thorough, incredibly knowledgeable, communicated well and were respectful. They truly went above and beyond, and I'm…
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.
Keith came out to review and quote our project. He was timely and informative. Then Thomas came out to install the windows - he was early (AWESOME), polite, completed the task quickly, and cleaned up after himself. We are happy with our windows too - they look great. We'll definitely work with this team again on our future window projects.
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…
Great job installing my front door. Would recommend them again
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 was a great choice for me to replace my window well. I had an existing window but was rotting and threatening to cave in. The team that worked on this was courteous, informative about steps along the way, and did a great job with clean up. Lead time and pricing beat out other competitors and the quality of the…
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!
I had a very good experience with WMGB from the very beginning. Set up an appointment at the home show, and we had Derek come out a couple of weeks later. This is not a place that 'needs both homeowners to be present' for the visit. I HATE those places! Derek showed up when he said he would, and was very friendly,…
Make sure to read the fine print…. Window was installed 3 years ago and they never tied into the drain in our house and it flooded our basement. We had to install a pump in the window well.
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.…
WMGB Home Improvement was so easy to work with, highly recommend.
My wife and I recently purchased a 1940s Cape Cod home in the Grand Rapids area and moved in during the middle of winter. We quickly realized how poorly insulated these older homes can be — especially upstairs and in the basement. The house was freezing! We were referred to WMGB Home Improvement for help, and the…
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…
I had a great and seamless experience with WMGB. They had great communication and professionalism. The finish product was excellent and at competitive pricing. Would recommend for anyone in the market for new windows!
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…
Derek at WMGB came out and went over our window options. Was very professional and explained everything. Sold us a house full of windows on the spot. Install was on time and everything went smoothly. Very satisfied with the experience. A++
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!
My first project with WMGB was a total success. From the initial meeting with Derek Worley (who was awesome) to the finished product (glass block window replacement), my needs were met in a professional and timely manner. So much so that I have another project in the works. Thank you Derek and WMGB!!!
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!
Outstanding experience (again) -- 4th set of glass block windows. Tom and Dan worked exceptionally hard and Derek was delightful to work with on the initial quotes. Great communication and product!!
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…
Darnell replaced our basement windows and they look amazing! He is absolutely fantastic at what he does. Very professional and kind. I appreciate the fabulous job well done!!! Will definitely be coming back for future window replacements!!! Thanks so much!!
Friendly. Great work, installation time very satisfactory.
Have nothing but great things to say about WMGB, from the ease of a remote inspection, to the ease of having the guys come in and do the work.
Old windows were removed and debris taken away. New Glass Block windows look great. Job was done quickly with minimal disruption.
I was very pleased with the service that I received from WMGB. Everyone was very professional.
The overall experience was good. The company was great to work with. They showed up on time, completed their work in a timely manner, and the workmanship was very good. The only reason I didn't rate them 5 stars was the cleanup. They left a mess in my basement. There were pieces of glass, mortar, and spray foam…
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.
I have use WMGB at my own home and at rentals. They always come through.
I was very happy with my new block windows, the guys were friendly knowledgeable and worked very quickly.
WMGB replaced all the windows in our '60s home. Start to finish... great customer service!
Replaced my egress well in one day, also located and fixed the damaged drain tiles causing my basement to flood. All for a bit less than the estimate. New well looks great and includes a ladder.
