My new Marvin windows are in and I am understandably happy with the whole process-though Nex-Gen Exteriors. These new windows are just plan beautiful. I now can open them up and get a cool breeze,though my home in the evening. That is why I love Wyoming and my new Infinity Fiberglass Windows.

Our names are Robert & Terri Costello from Gillette Wyoming. We went with the Infinity fiberglass windows though Nex-Gen Exteriors in Casper Wyoming. This is a great product And Nex-Gen's Installation crew was top of the line in every way. I am a very hard person to please,some people even would call me something else. Terri & I do love everything about our new windows.We can get great thing's done in Wyoming after all.. The only little thing that we forgive them for, it did take awhile to get our windows,they are really busy ,but worth waiting for. You will have your windows from Marvin for ever,done right with Nex-Gen.Thanks to our installer Steve and John also to our rep Larry. Also Maria was aways great to talk to when we called the office. Thanks Nex-Gen Exteriors.

It all came out wonderful with our new windows from Nex-Gen Exteriors. Perfect Installation. We got more than we thought we were getting ,it really is perfect. I love the Everwood interior .Thanks Brent ,Joe and John. From Jill Kohee. Fort Collins Co.P.S.( We made the right chose in Nex-Gen).

We love our " New" home- That's precisely how we feel about the results of the Nex-Gen Exteriors siding we had put on our home. Cost of heating & cooling (dropped) ,beauty of our home,( went up). Over all cost (,worth it.)!!

I was so impressed with their diligence ,courtesy attention to detail and conscientiousness. They worked in a professional manner and were attentive in completing their work until it was done. They made me feel confident that it was done right. I will not hesitate to call your company for other future work .

Thank you Nex-Gen Exteriors-You guy's were great -our new fiberglass windows are great- And now lower heating and cooling would be also great. We love our new Marvin windows.

Our new windows are very-good.infinity from Marvin by Nex-Gen Exteriors fiberglass windows,was worth every penny.All pro in every way-start to finish.thank's Nex-gen-Great job Brent!!!,you are # 1.

Our New windows are (BEAUTIFUL).!!! We bought The Infinity from Marvin fiberglass windows by Nex-Gen Exteriors in Casper wy. This was one of the best thing's that I've ever done. Our sales person, told us about the Quality of the installation crew and they were great!! They were employees of the company. ( NOT SUB-CONTRACTORS). We don't like just having anyone in our beautiful home now day's. Nex-Gen's guy's were clean -neat and you could trust them in your home. Not like the painting company that done the inside of our house two years ago. That was a bad thing to go though. My wife found one of them going though her dresser in her bed room while they were working.( This was terrible}.We are recommending Nex-Gen Exteriors because we need too!!. We Love everything about our new window's and Nex-Gen Exteriors out of Casper Wy. Tony Kale & Veronica Riley Gillette Wy.

This is the second time we contracted with Nex Gen Exteriors for our new windows. We had 4-new infinity replacement windows done in April 2013- .Now they just finished 4-more and a patio door this time. They had a different installer do this job, but the same great results. We do recommend them with out any question. We will be finishing up the rest of our windows in April of 2014 though Nex Gen Exteriors and the Infinity from Marvin Fiberglass windows.

I had windows put in my house in Casper, Wy where the wind blows 50 miles hr. and they have kept the noise out and my gas bill has gone down from $120 last year to $85.00 was highest sence I had my windows installed in October 2012. I also don't hear the teens radios anymore as they drive by. The men that put them in were very polite and did a GREAT JOB. I had a former work person call me and I recommended them to her and she brought some. They have called me to make sure I am happy several times. THANK YOU
