Nex-Gen Windows & Doors

The ordering process and installation was smooth and easy.

After purchasing our home 2 years ago, we knew most of the windows needed replacing. Then the hail came, so we bit the bullet and decided to replace all 15 windows and the patio door as well. We started our homework and research and came up with 4 different companies to have come and show us their product.
As a daughter of a Sears salesman during years of 1970 to 2002, I use to watch him sell appliances to every walk of life. He was one of the few salesmen that tried to sell you what YOU wanted and could afford, not what THEY wanted him to sell you. And he was honest. Still a salesman, but honest. This is what I found in Ted Rajewski. He was efficient, smart and honest.
Everyone from Janice, to Angelo to gentleman that came to measure the windows to the installers. They were all very, very easy to communicate and talk with, which meant things were done efficiently and...

We received excellent service in replacing two large windows in our house. Measurement was expertly done and the windows were delivered on time. The price was reasonable. The installation crew were prompt and both the installation and its supervision excellent. We know because the weather turned really cold so we knew for sure. We have also had a followup visit. This is a local business so I know I can contact them for any additional followup I want.

Their windows appear to be good units. Initially, we had trouble with drainage on slider windows that was eventually remedied, but it took a number of visits to achieve a solution. In the end, it was determined to be a manufacturer-caused issue that once analyzed, was easily remedied. We had damage from a bad hail storm and they lived up to their warranty policy with replacement/repair.

I would not hesitate to recommend this company. Ted Rajewski went above and beyond to help me design and choose a new front door! He was prompt in responding to my texts and came to my home more than once to make sure I was comfortable with my decision. He was professional, knowledgable and friendly. As a customer I was listened to and valued.

Several years ago, Nex-Gen installed Marvin windows in our home. We were extremely pleased with the care and professionalism of the team. Recently, we had an older Marvin patio door with a slight problem. We contacted Nex-Gen. Cari, the receptionist, was very nice. Mike called to set up an appointment to look at the patio door. Again, we were very pleased with the service provided.

We reached out about replacing our windows. We had other quotes but felt pressured and that they weren't listening to what we wanted. Then Ted came over, listened to what we wanted, quoted what we wanted and didn't pressure us into more. Fast forward a couple of months and we were ready to move forward. Ted came back, answered our questions, never pressured us and never over sold us! We are so happy to be working with Ted and NexGen windows! We highly recommend them!!

Windows were installed and I cannot recommend them enough!! The installation was quick and went smoothly. Neil, Shane and Shanoin (sp?) were great with the installation!!

Fast, high quality product. Would recommend Nex-Gen to anyone.

Good quality products and quick work during the installation. Personnel were responsive to concerns. Scheduling the installation was a bit challenging.

Years ago i installed replacement windows fro, NEX-GEN. So when I needed a new storm and main front door, i called them. After talking with other companies, I chose Nex-Gen. I am very pleased. The doors are tight, strong, substantial and easy to open and close. They feel and look great! The installers were pleasant and did a good job.

Neil and his group did a very good job installing and cleaning up after the work was done.

The service was great and the installer, Mike, was very professional and courteous.

I had the pleasure of meeting a couple of Nex-Gen employees - Cari and Mike, when my vehicle broke down stranding me on 25. Cari and Mike stopped to see if their could help and were incredibly gracious and patient with helping me out of a difficult situation; even going out of their way to give me a ride to Denver. I’m from Virginia and in Denver visiting my daughter and haven’t used Nex-Gen services, but if Cari and Mike are an example of the quality of Nex-Gen employee (and I suspect since the company has a BBB 5Star / A+ rating the owner - Brent, is very selective with picking quality, conscientious folks for his Teams - Cari and Mike are just an example), I recommend if you’re looking for services they provide to give them call. I have a feeling you won’t be disappointed.

We recently had Nex-Gen install five new windows in our basement; we had all of the upstirs windows replaced earlier; so this is our second time with Nex-Gen. We could not be happier with the product, their installers and their personal services. Our installers (Ed and Aaron) worked tirelessly and with excellence and kept us informed about each step in the install process. Neil was here three times and followed up with us to ensure we were happy with every detail of the job. This is a GREAT company with people that care about their customers and stand behind their product. We would HIGHLY recommend Nex-Gen to anyone looking to replace their windows and/or doors!

Highly recommended. I would use them again in a heartbeat

Nex-Gen did a wonderful job start to finish. The sliding glass door was just what we ordered and the installation went smoothly. Steve, Arthur and Neil were on-site to make sure the job was done correctly and that we were were satisfied. Definitely a positive experience and a great result for us.

Fantastic job and great service! I would recommend Nex gen to everyone.

What an amazing experience. Over the last couple years we have had so many bad experiences with other companies. We had a new garage door installed (terrible craftsmanship) a new front door (screen door still isn’t right after countless retry’s) a new patio door ( so bad we had Next -Gen replace it after only one year). So we were really hoping that this window replacement would somehow not be a disaster. That’s when we found Next-Gen. from the time Dan the sales representative stepped into our house til the last window was installed we have been so impressed. Great product, great installation. Everything works great and we now love our new patio door. If you are looking for a great window door replacement Next-Gen will deliver!!

We love the windows! The entire house was finished in one day and they cleaned up great. We have no drafts or streaking even after all the rain and wind. And the light is amazing, not to mention the price. We are so happy, we've just ordered doors. Highly recommend

Nex-Gen doors are high quality and come with a lifetime warranty! We had great, thorough service from Thomas and Xavier for some maintenance needs on our front entry door. So happy with this company and product!

I would highly recommend this company. We had these windows installed throughout our house and they look great. The installation was pretty quick. The few issues that came up, the company was quick to resolve.

We had Nex-Gen replace our windows and sliding glass door. Neil Horn was very professional. He answered my calls promptly, addressed every concern I had and has checked multiple times to ensure that we are happy with the work. Roberto and his crew did a good job on the installation. We are very pleased with our new windows and door and would highly recommend Nex-Gen.

I highly recommend Nex-Gen if you are looking for quality attractive windows and doors. I just had them out for the second time to install two doors and two windows. They replaced my other windows and doors a few years ago. I really noticed the reduction in heat and cold and just love the way they look so I knew Nex-Gen would be my go-to Company. I can't say enough about all the staff that I worked with. Justin, the sales rep, was great at coming up with options that met my budget while not sacrificing my wants. He even helped me out with some non-related home issues while here. Steve and Arthur worked tirelessly doing a meticulous job on the installation, making sure I knew everything about the products and made sure everything was cleaned up after the work. Neal did a great job managing the project and ensuring that I was totally satisfied while encouraging me to call with...

They have done it again! Reuben and his crew put in a new window, and my house looks amazing! They took out a fake bay window and transformed the entire look of my house. I can not say how wonderfully respectful, honest, and trustworthy the entire company is...Chris, Janice, Thomas, Reuben, etc....! If you need windows, doors , or now siding, these guys are the ones I would call first (it will be your only call).

Good experience overall. Very professional, good quality windows, and quick install.

In April, Nex-Gen Windows & Doors replaced the entry door along with 8 windows in our home. In the 4 months following the upgrade, we couldn’t be happier. The team was so friendly and helpful through the process. We never felt pressure to buy and there was no upselling or add-ons to the cost. The crew that performed the install was courteous, and I was surprised that the install was completed in a single day. Neil, the project manager, stopped by two times through the day to ensure the project was on track and answer any questions. The quality of the product has been impressive, and we love the look our custom front door. We definitely recommend doing business with Nex-Gen Windows & Doors.
