Nex-Gen Windows & Doors

We have had a GREAT experience with Nex-Gen. Ted Rajewski worked great with us getting us new windows (14!) for our house. We made a BIG mistake and went with someone different a couple years ago for three windows and BOY - Nex-Gen window quality is so much better. Installation was smooth, great communication. All of our interactions with all of their staff, sales, measuring and installers and final inspection was great. We wish we had made the choice right the first time and sooner. Ted listened to our needs and did a great job working with us!

Wonderful Company! Highly recommend them and we have to our neighbors and our son! The staff was very nice, efficient & skilled! They protected our surroundings & cleaned up very well after the job was done. They made sure we were happy! A foreman came by to make sure all was tip top. I finally got my garden window and I’m a happy wife, happy life with view of beautiful Rockies!

Great windows and amazing employees.

What a great company! We had the best experience with Nex-Gen in their replacing some windows for us. Our project seemed to come with a couple of challenges and we could not have had a better outcome! Ted Rajewski was our sales rep who came to look at what we needed. He has a wealth of experience and was confident in a great outcome. We had some additional wood around the interior of the old windows (three windows) for attaching our wood shutters. We wondered if that wood needed to come out for the install. Ted assured us that if that was needed, they would put it all back together and it would look the same. As it turned out, the installers did the job without removing the wood at all! Then there was our old garden window over our kitchen sink, for which we chose an awning window. My concern was we would lose a lot of depth on the interior window sill. Tony, our measuring tech from...

After mixup on initial bid process, all went well. Nex-Gen worked around our schedule, crew was on time, on task, pleasant to have “invade” our home, accommodating, polite, knowledgeable, careful and neat. Crew leader Robert continually checked that we were satisfied at every step. He did a couple of extra “fix ups” in our window openings. The job by nature is messy but they did a complete cleanup. Project Manager, Joe Martinez, checked several times, and reported my concerns with the product to Marvin rep. He also advised on finishing the windows (we will seal the ultrex& wood before Nex-Gen returns to fill/caulk seams). He assured us that even though we accepted the finished installation, if we note additional items, Nex-Gen will return and address those concerns. Although we have some concerns with the quality of the Marvin finish work, we are pleased with our...

A good experience from purchase to installation a professional job well done

Superior product and Joe was a wonderful project manager and his crews really know what they are doing. Thank you, Joe and crew. I would have given 5 stars but there were some glitches in early communication with my install, but they were handled quite well.

Mike did a great job. Would recommend Mike and Next Gen

Nex-Gen did an amazing job installing new windows. Everyone was so professional, courteous & they got the job done in great time. We love our new windows & will be back for more. We highly recommend Nex-Gen.
