Replacement Windows Denver

We just had our windows replaced on our entire home by Jay Lillien and his team. This whole process was a perfect example of professionalism and expertise that far exceeded or expectations. Jay has an incredible wealth of knowledge, he walked our entire home and gave advice on every window. From the aesthetics, functionality and cost, it was apparent that Jay is an expert in his field. The install team was equally as talented, our windows were measured perfectly and these guys were simply awesome. Their attitude, skill and work ethic were A+. We had shopped 2 other window companies and without question, 303 Windows was far superior in value, execution and cost. My wife and I give this company our highest recommendation and our windows are beautiful!

My wife and I went through 303-WINDOWS after seeing the prices of many of the “Name Brand” companies. We were quoted 25k-30k for 21 windows by these companies. When Jay came out, he explained everything to us and was non invasive. He quoted us at 12k for 21 windows! I was a little concerned about the quality at first, but after talking to a couple other people, those concerns were abated. The windows were installed in 1 day. The crew that installed them was respectful and fast. I couldn’t have been happier with the service I received and the windows are ABSOLUTELY WONDERFUL! The warranty is unbelievable! A mouse chewed through my screen on my basement window, after a 5 minute phone call, Jay had a free replacement on order for me. I would recommend anyone looking at this review to stop wasting their time looking and simply go with 303-WINDOWS.

Thank you again to all the staff at 303-WINDOWS.

Jay, We are extremely happy with the 12 replacement windows for our daughter’s home. They look beautiful, quality is great and function wonderfully and the cost was very reasonable. Thank you for your wonderful recommendation on the picture window as well.

Your crew of worker bees was so impressive! Friendly, courteous, hard working gentlemen and not loafing or taking cell phone calls. Great clean-up job too.

What a superb business you have Jay! We are so happy we found you and your team.

It was a pleasure meeting you and thank you so, so much!!!!

Jay and his crew did an amazing job! I had a patio door installed, and a large window with a half moon! After meeting with multiple window companies, I met with jay. I had used Amerimax windows in a previous home and loved them! The whole process was quick and painless. I have recommended and will continue to recommend 303 windows and also use them to replace the additional 10 windows in my new home!

Jennifer Schneider

Jay is simply a Rockstar! We looked at many window companies and started out having Jay and his crew replace the windows in one of our rental homes. It was done perfectly. We went through the process again with our home windows and narrowed the choice again to Jay. There were other people we interviewed who promised the price no one else will come close too- but Jays price was better out of the gate. We visited other homes that were done by other companies but Jays crew goes the extra mile. I will say we are very picky and Jays crew was simply amazing. I also want to say- we were told products did not exist to solve some of our big window issues, but in fact Jay knew the product line better than the other companies and with a call, he confirmed the products did exist. Thanks Jay- our house looks bigger and the windows are so much better than the original wood windows we had. My Wife and I commented how the quality of the glass was much better than what we had. Thanks again! 5 Stars every day!!

I would recommend 303 Windows to anyone who wants a quality product at a reasonable price-point with quality and accountable service. Their only product, Amerimax, is built in Colorado especially for this altitude, and intense climate and sunshine. The owner is committed to your satisfaction, and the installers couldn’t be nicer or more accommodating. My install had some issues, and the guys worked until they attended every detail.
I am very pleased with the value and service I received. They strive to maintain their 5-star-only rating, and they deserve it.
You won’t be disappointed.

Sonya Riebhoff

Jay and his crew did an amazing job! The entire experience from start to finish was easy and low stress! Jay came out to our house and gave us our options with zero pressure to buy from him. The windows were installed in the timeframe he gave us. The crew finished all 16 windows in a day while it was cold and snowy out too! The price was great and the quality of the Amerimax windows is exceptional. If you need windows call 303windows!!!

Michelle Milholm

We received a wonderful service from 303 Windows and Jay Lillien. We knew the windows replacement could be expensive. We have 52 windows inside our house. So we made sure to work with the window company having a great service, quality and price. 303 Windows is outstanding for every of the category. Their quality is very high, their workers are very professional and custom-oriented, and they provided us many alternative solutions about how to save cost (e.g., combine windows together, even that means more work and less money for them). I did the first job with them in September, and signed up for the 2nd job on the day of their completion. And now the 3rd one. You will be very happy if you decide to go with them. Best of luck to your house project!!!

My experience with this window company was excellent. Jay was incredibly helpful through the process of having our windows replaced after a massive hail storm. He was also very detailed in his inspection. He took the time to investigate our windows and determined that they were upgraded windows (other window companies did not notice and we would have received less quality windows than what we originally had). He communicated with my insurance company and made the process very easy and was able to get like-for-like window replacement. He was available anytime I had a question and was prompt at returning emails. The entire process was very smooth and I would highly recommend this company. My windows look great too!

Christy Anderegg

I LOVE the Amerimax windows and am thrilled with how quickly and easily everything went with Jay and his crew. The windows are beautiful and sturdy, easy to open and close and clean. Jay doesn’t need high pressure sales tactics when the product is such high quality! He also helped me decide on the different options available in the look (who knew there are so many?), and I’m so happy with how great it all looks.We are looking forward to all the fresh air we’ll get come spring, when we will open and close windows with abandon!

Three years ago I had 303 Windows install 10 windows throughout my entire home. Their quote came in the lowest amongst the three I solicited, and I believe their product is among the best available for vinyl windows.

My experience was excellent. The owner himself came out to our home to do the quote, and he was very thorough. He provided an excellent recommendation for a horizontal slider where it would have been inconvenient to have a window that slides open vertically. This is advice that could only have come from an experienced tradesman that was interested in the best solution for our home.

After signing the contract, the owner continued to communicate with us to keep us updated on the progress. Once the windows were ready, the installation was quickly scheduled. The two gentleman that came out on the day of install were professional, thorough, and quick. It only took a single day for all 10 windows to be installed, and they took care of all the clean up.

Three years after install, the windows still look the same as the day there were installed. They operate smoothly, and their white color is still brilliant. I can see no signs of discoloration.

The only recommendation I would make is to ask them to use a higher quality caulk on exterior walls that get a lot of direct sunlight. All interior caulk has held up well, and any exterior caulk that doesn’t get direct sunlight remains okay to this day. I realize that caulk must be replaced, but the caulk that was in direct sunlight was quick to crack and lost a proper seal within a year. There is better caulk out there that can withstand the sun, but it does cost a little more.

Regardless, the product is great, the people are great, and I would highly recommend these guys if you are looking to get vinyl windows.

Mark Derham Lakewood

Great experience from start to finish! Reliable guys, and unbelievable pricing compared to 3 other well known companies we priced out. Our windows came in earlier than anticipated and the install was quick and flawless. The windows are amazing, very high quality and the difference we hear, see and feel is well worth the investment!

Tiffany Fitzpatrick Denver

We can’t say enough good things about our window replacement experience with 303 Windows. First Jay met with us and provided a detailed review of Amerimax Windows and we agree that the windows are of excellent quality. We had 36 windows and a new patio door installed, and Rick and John were so professional and friendly. They replaced all 36 windows in 3 days and they were excellent. They paid extra attention to every detail. We noticed that they blocked noise from outside our home. The quietness over our old windows was an added bonus. The appearance from outside our home looks great. We rate them a strong 5. Couldn’t be happier.

Steve Nixon Centennial

We had our 16 windows installed in a day. Rick and John did a great job, were professional, courteous, efficient, and took great care with our house- all the while keeping the kids laughing as they watched them work. The windows look great, and have already made our house better- canceling sound and allowing us better air flow. Thank you so much.

Paul Nerves Denver

Truly the most professional installers we have ever been associated with! John and Rick were “”top notch” in the way they represented themselves and the company. They were prompt, cleaned up after themselves, and when we had questions, they took the time to ensure our questions were addressed. This wonderful experience started when Jay Lillien came over to provide a quote and spoke about the Amerimax windows. The detail he provided was exactly what we needed to make a decision. He was honest on the arrival and installation date of the windows. He also kept us informed along the way. The windows were installed in a timely fashion and are AWESOME!. We feel like we have a new home! Between Jay, John, and Rick, there are a three words that come to mind; credible, trustworthy, and ethical. They exceeded our expectations and we highly recommend them. Thank you for allowing us to do business with YOU!

After talking with several neighbors and interviewing three companies, I chose to go with 303 Windows a.k.a. Centennial Home Improvement. Jay is easy to work with, lays out the facts clearly and honestly and has a great product with a Amerimax windows. His longtime installers, Rick and John, are pleasant and easy to work with. I am happy to recommend this company.

Jay,

Our new windows have provided an added joy we’ve not had before. Not only this winter did we immediately experience the added warmth and notice on our heating bill, but both friends and family couldn’t get over our “new room” effect.

Thank you.

The Jamisons Lakewood, CO.

Dear Jay.

We’d like to thank you again for our new windows. We were happy with the entire production from start to finish. We had previous negative experiences with hard sell people, so we found your factual, no-pressure approach to be refreshing. We also felt that your prices are very reasonable compared to other dealers in the metro area.

We can’t say enough about the professional installation. They were not only fast, but conscientious and thorough. They even helped remount some of our hard-to-reach window coverings-a job they weren’t required to do by contract, but did anyway. We greatly appreciated their efficiency and good nature.

We don’t have central air, so during the summer we rely on our whole house fan to draw in cool air during the night, then close down the windows during the day. We have been amazed already at how well the windows keep the cooler air in and the hot air out. We have high hopes that they will also keep us from losing heat during the winter. So far, we are extremely impressed with the Amerimax windows and only sorry that we didn’t make the change earlier on.

It’s sometimes daunting for a homeowner to decide what company to choose to make theses sorts of major improvements. We felt like we were treated with respect the entire time and appreciate the quality product and installation you offer. We would be happy to recommend Centennial Home Improvements / 303-WINDOWS to other potential customers.

Thanks again!

Hi Jay,

We had Jay and his installation crew install 4 windows and a patio sliding door about a year ago. They did such an excellent job that we will be having them install the rest of our windows in the near future.

The service was great from the beginning. When we bought our home, Jay was recommended by our home inspector. We called him on a weekend expecting to schedule an estimate later in the week, but he was able to come out immediately. He gave us a quote that day, but we wanted to check out other places since this was our first time buying windows. We were able to get estimates from two other places including Home Depot. Their quotes were so high (one was twice the amount) that we decided to cancel our third estimate!

The installation was done professionally and efficiently by two great installers. They were courteous and very respectful with our new home.

We have been very happy since purchasing our new windows. The quality of these new windows surpass the old windows that we will soon replace. There is a huge difference between the new and old windows! We highly recommend Jay’s Amerimax window’s to anyone.

Dear Jay,

I want to let you how much I appreciated the great service Centennial Home Improvements/303-WINDOWS provided, and the quality of windows that were installed at St. Therese School this past summer (July 2006). It was a pleasure working with you, as well as your installers who installed the 186 Amerimax windows in the school. Your installers were very professional as they worked along side the company that removed the windows and did the asbestos abatement, which helped the process move along smoothly without any difficulties, plus making it much easier for me. The quality of craftsmanship, pride of workmanship, and the daily cleanliness after each workday was great. This makes working with a company a pleasure.

Last winter our heating bills were out of control and we felt that replacing the 50-year-old single pane metal windows would help tremendously in reducing the heating costs. Already we can tell a difference as one of the two boilers in the school has been down for a couple of weeks during some cold days in October, but the school still stayed comfortable with one boiler doing the job. The teachers not only are thrilled with the comfort of the rooms and the ease of opening and closing the windows, but also the quietness in the rooms due to the quality of windo which helps keep the outside traffic and noise down. We have had many comments on the appearance of the windows from parents and parishioners which in itself makes it all worth it.

Again, we are very happy with the windows and I am so impressed with the service from your company that I would highly recommend you to others. If I can be of any help to you in any way, please do not hesitate to call me.

Dear Jay,

I want to thank you for installing the windows in our home. It was a nice change to meet with you. You were not pushy like the other salesmen. You were helpful and informatitive, and I was very impressed with the workmanship and business manner of your installers. I have not had one problem with my windows since they were installed.

As you know our house backs to a somewhat busy street, so the biggest difference I noticed immediately was the noise reduction. Now that our Amerimax windows are in I can’t even hear my neighbors dog barking at night. I noticed the quietness after the first day, when only half of our windows were installed. The windows really make a huge difference.

The other improvement to our house is that the heat from the sun does not fry our family room anymore. Now, in the summer we don’t even run the air conditioner all that much. The technical improvements to the glass make a big difference here with the Colorado sun.

Our Amerimax windows are a great improvemet to our home. Thanks!

Jay,

I am writing this letter to thank you for your services. As most homeowners do, I was dreading having work done on our house. However, you made this experience very pleasant for us. The crew that was sent to our home were extremely efficient and friendly. They made sure that our personal items were cared for, and cleaned up after themselves.

After the work was complete they took the time to do a walk through with us. This says to me that you care about your customers and our satisfaction. So once again, thank you.

Gloria and Bob Hale Denver, CO

Jay,

We are really enjoying our new windows. We had eight quotes and yours was the lowest, but the main reason we had you install our windows was because of your creative recommendations. The casement windows look much better than the sliders would have. Thanks, Jay!
