Wonder Windows did an amazing job on replacing all of the windows on my home. The quality was top notch!!

BEYOND DISAPPOINTED! The quality, craftsmenship and customer service is mediocre at best. Spent over $60,000 on 21 windows, 2 doors and a shower install in 2025. Here are all of the calls/fixes we have needed; one window didn't open/close properly. One was missing a screen. The person came and literally just scraped the broken window frame with a knife and didn't bring the screen so that was another call and visit. The new storm door and frame somehow pinches themselves together if the wind blows it too hard when closing. The only way to open it is to either unscrew the frame and take the bottom of the door apart or rip the frame off the house if you're stuck outside (this happened twice before someone came). The "fix"- a few long screws strategically placed that look cheap and ridiculous. But the actual window install went well enough that we made the mistake of thinking they would be good at replacing an old jet tub with a custom shower. The contract was signed on 11/10/25. Install was suppose to be in about 60 days. Once completed, the shower would be measured so the door could be ordered and installed 4 weeks later. The shower was completed 3/4/26. It looks ok. We were told it would be seemless except the corners but one was added and not centered so it looks a bit stupid and has gaps in the grout. We figured they could regrout when they came back with the door. On 3/25, 3 weeks later, we called to follow up because we had not heard anything. We were assured that the installers had measured and the door was ordered. The door install was scheduled for 4/9 from 10am-12pm. We get a call on 4/8 that they will just be measuring on 4/9 because NO ONE MEASURED THE DOOR. No one even noticed that no one even ordered the door until 1 day before the scheduled install. (And just an FYI, my husband forwarded pics of the newly installed shower on 3/25 because we were concerned about the small bumpout. This was not part of the original layout and we were concerned it would effect the door.) So we get 1 days notice and it will be at least 3-5 weeks late. (I cancelled 5 appointments for tomorrow's install!!) And every person we talked to today says the same thing, "Sorry, best we can do is measure tomorrow, order the door and hope it arrives in the 2-4 weeks". Not one person has said with any sincerity, "I'm sorry, this should not have happened. We dropped the ball." Alan told me "it wasn't his fault cause he is only suppose to order the door so I need to talk to someone else". The last guy, Matt D, said this is not how the company normally operates yet HUNG UP ON ME 4X! He said it was because he was using an app to call me. An app that hides his number. The 5th call back was using his actual phone. As I said in the beginning, we began this shower project 11/10/25, it is now 4/8/26 and the door has not been measured or ordered yet. If you are considering Wonder Windows don't. Just walk away. Once they get your money, they do not care about your business. read more

The window installation itself was good, however, the trim work was not acceptable. They came to check after the windows were done and agreed that the window trim must be redone. They sent the same crew out to redo the trim and with the same result. Some windows were done 3 times. The chalking looks like a 3 year old did it. They never sent anyone to check on the final trim work. Never did a follow up. Very disappointed. Once they get your money they don't want to talk to yound read more

Had an appt for a salesman to come to my house. Wife and I both made sure to be home at that time. No one came, no one called. When I called them to see what was going on no one answered the phone. I'll look at it as the Universe protecting me from doing business with incompetent jerks read more

Request Mike and Harold! Mike and Harold went above and beyond for us and they did and excellent job! Each day when they left you would have never known they were here other then now we have beautiful windows. Our house was built in the sixtes so I was a little worried that there would be issues getting them installed properly but I couldn't be happier! I don't usually leave reviews but in this case I felt I needed to. Our windows came in ahead of schedule and installation was completed as promised. Teresa read more

I had comfort windows put in front windows and Wonder Windows do the rest of the house. The craftmenship and quality of the windows is night and day. The windows themselves are thicker, the parts have metal to help keep them airtight. The aluminum used by comfort windows on the outside is cheap and I already have a dip in the window. You can feel the difference in the thickness by Wonder Windows. I am simply amazed by the windows. The workers who did the trim are artists. I cant say enough about how pleased I am. read more

The staff here is a joke the tell you one thing and then do another or tell you one date for a installation and put something else in the computer there salesman promise you a date they cant keep there promise so in short i will never buy windows from this company again the only reason they put this window in my home is because they would not return it. Turned our world on end when they tell you things that are not true then tell you they never said it when you have them on recording the will try and make you think you did wrong i will tell you how they only have one set of instiller for the window i bought when there a company with a name like wonder window they should be able to install a window read more
