“We had a garden window that the seal broke and there was condensation in between the panes.”

We had a garden window that the seal broke and there was condensation in between the panes. Called Apex to have a quote done. They came out that week and gave a quote way lower than I was anticipating. I called the next day to schedule the repair. They sent someone out right away to do an exact measurement and then had the new piece of glass in the next week. All of the gentlemen that came out to do quote/measurement/install were super nice and professional. Work was completed quickly and seamlessly. Definitely will be calling them again if we have any window issues in the future!!

I've dealt with a lot if contractors over the years and these are some of the best. Responsive, reliable, prompt, fair. You call, they inspect, they schedule, follow up and then show up. They do what they say and do it well. I highly recommend.

“The Apex team is highly proficient at what they do, and their pricing is very competitive compared to the market.”

The Apex team is highly proficient at what they do, and their pricing is very competitive compared to the market. I used their service to fix one of my windows, and they responded promptly by coming to my home for an estimate. They provided a clear and thorough explanation, which I really appreciated. I had a broken double pane glass window, and they fixed it in no time. Overall, a very professional and efficient experience.

“Our Pella window glass shattered due to extreme cold.”

Our Pella window glass shattered due to extreme cold. I called a few places, but Apex Window Werks stood out as the most structured and organized. They were also upfront about their minimum pricing. Their project manager came out within a day or two to take measurements, and the job was scheduled right away. The team replaced the glass the very next day. The cost was reasonable, especially considering how expensive window replacement can be. I highly recommend Apex Window Werks. They’re honest, punctual, and truly great people to work with.

“APEX Window Werks recently replaced 16 foggy window panes in our home, and the entire experience was excellent.”

APEX Window Werks recently replaced 16 foggy window panes in our home, and the entire experience was excellent. The work was completed within one day, and the results are outstanding. We were particularly impressed by the efficiency of their process and the quality of the finished product. Most importantly, all of the new window glass comes with a 20-year warranty, providing us with great peace of mind. Vlad delivered exceptional and professional customer service throughout, and the technicians were friendly, punctual, and highly skilled. They did an excellent job. Highly recommended!

“Apex was very responsive in replacing 3 window panels.”

Apex was very responsive in replacing 3 window panels. They were quick with an inspection and estimate and by far the best price quoted. Their installers were polite, professional and very quick to install the panels. Highly recommended.

“Apex replaced 7 of my windows recently.”

Apex replaced 7 of my windows recently. I live on the 6th floor with a variety of large and small windows. The seals were damaged on seven of the double paned windows. They came and gave an estimate quickly. It was a good price and they were able to return with the new glass within 2 weeks. They also replaced 3 unusual hinges on a few of my vertical windows. These parts took time to get or they probably would have been able to do the work even sooner. overall, great company with professional and talented craftsmen. The windows look amazing and I could not be happier.
