Nex-Gen Windows & Doors

We had NexGen Windows and doors replace an old window for us in September. It was replaced with care. Neil, Don and Chris did an outstanding job. I was most pleased with the finish staining of the new window to match our current kitchen done by Chris.
Thank you
We will use them again.

I really appreciated the attention to detail , professionalism, kindness, thoroughness and customer service Neil provided. They were on time, clean, courteous and I would definitely use again. Thank you!

We just had the windows on our main floor of our home along with a sliding glass door replaced by Nex-Gen. We knew that Marvin is considered an excellent company for doors and windows. The bonus was how wonderful Neil Horn, Dan and the crew were every step of the way. I highly recommend Nex-Gen for both excellent product and services.

We have found Neil Horn to be just an outstanding salesman for this product. Mike was a very professional installer. They were both professional and personable. Evidence is that we are buying more windows from Next-Gen. that we had not considered before. Simply put, they are a great representatives for Next-Gen windows.

The men that came to install were very professional and cared for keeping the dust and carpet clean. I would recommend them. There very efficient and friendly.

Smooth process. Neil, Steve & Aurthur we awesome.

We can’t say enough about the excellent service from the NexGen team. Chris came and stained the casing around the ProVia front door, and it matches perfectly. He also stained our new Infinity kitchen door, and did a beautiful job. Our doors are gorgeous! Thank you Chris! Neil always makes sure that we are happy with our windows and doors. He has helped us so much! Thanks NexGen!!

We have 44 year-old Marvin wood windows in our home. The 19 windows are still beautiful. We put storm windows on a few years back, and unfortunately there was a lot of condensation between the primary and storm - especially on our upper story. We were ready to replace them, with a quote of $36,000 from a local contractor. Before this, we called Nex Gen in Fort Collins as we thought a Marvin replacement might be a great solution. The staff was superb - so caring and friendly! In September Ted drove 105 miles (one ways) to Sterling for a consultation. He said our windows were in excellent shape, and he felt three holes drilled in the bottom of the storm windows would provide air flow - and prevent this condensation. My husband did this recently, and the window condensation problem was solved. We couldn’t believe a simple fix like this could solve the issue. Ted didn’t try to...

Salesman Neil was fantastic, and the install team of Steve and Arthur were great. Would highly recommend Nex-Gen

I can’t say enough good things about NEX-GEN! The entire process was professional, and I am extremely satisfied. Neil came out to give me an estimate, explained everything thoroughly, and gave a great presentation. He followed up and was always quick to get back to me. The installation team, Steve and Arthur, were wonderful. They were so nice and professional, and the installation was completed in less time than predicted. Neil came by during my installation to check on things, and I felt really taken care of by this team. They even helped me with a small project on another window that wasn’t being replaced. Just great guys!! They really stand out from their competitors, and I love my new windows!
