A triple pane sliding glass door to my lanai was ordered at the end of September 2025. I was very impressed with Ryan, my salesman. He said he'd be there for me through the whole process. That was reassuring. But then the wrong door was delivered November 13th. (2 pane glass not 3) and because I had already paid for 90% of the door, with no door in sight,
(I got an email regarding the reorder, but I was hoping to speak to a person regarding this situation, and no one called.)
this was a big problem for me, and I got a little nervous. Remembering what Ryan had said, I called him on December 4th. He said he understood my concerns, and he would check into it and get back to me. He did not. Not wanting to bother him, I let it go. My error. On December 17th, Shea from scheduling called, to let me know my new door was in, and would be installed in a month, as it required a 2 man install. Install date was set for January 14th. So on January 13th I prepped my install area again, but when the installers showed up this time, they only had the glass panels, no frame. I could not believe it!!
Nobody had any idea where the frame was. And in my mind lurked the question how the frame had been separated from the glass panels. (ie when I sent back the 2 paned glass door in November, I had chosen that a whole new door be ordered, not just a glass replacement. So this was confusing. And disturbing. Did I get the right door, or just some piecemeal replacement? I tried to let that worry go.) But to continue. At this point in January, Amy in scheduling had become my contact person, and she was very helpful. She gave me her personal phone line so I could get directly in touch with her. It took 2 days, but they'd found the frame and the installers were to arrive on the 16th between 8am and 11am. Amy reached out to me at 10am, on the day of delivery, letting me know they were running late. The installers arrived at noon, and were very professional and thorough through the entire install process. I had no issues at all with them.
I do believe however, that the measurements taken of my door were a couple of inches too short. The threshold of the bottom runner is so high I have to be very mindful to take a very high step, or I stub my toe. This was NOT an install error, I am sure, They had to fill in the door from the top opening as well as build it up from the bottom to make it fit. Perhaps I should have let somebody know of this, but I was in no frame of mind to go through another ordering process, and decided to just live with it. Whether or not it will become an issue at rersale, remains to be seen.
Champion did give me a 3.5% reimbursement for the delivery issues, which I do appreciate. And Shea was very helpful expediting this process.
The door being too tall is another issue. But since I would not go through another door ordering process, it's a mute point.
But I have stated my concerns, and hopefully they will be duly noted.

While the installation team was professional, the project is not fully complete. We are currently missing three screens, and six screens were measured incorrectly and need to be remade. Although a service request has been opened, we have not received any communication regarding timeline or next steps. More proactive communication and quality control before completion would significantly improve the experience.

Additionally, we were not informed that the black exterior finish is painted rather than integral to the material. There are visible scratches on multiple exterior frames. Given the premium price of these windows, clearer expectations about materials and finish durability would have been appreciated.

Not sure

The Champion of Denver region from the start to the end did nearly everything wrong. Their sales department said they had built a number of four season rooms in the mountain areas of Denver. They said the 4” frame would be right when it didn’t pass the snow load requirement. Not only did it have to be upgraded to 6”, but it required addition beams. This held up the design for several months. They then let it sit in the county building permit department for months, shifting the install/completion date from Aug/Sept to this Feb (a year later). The thing they did do right was not charge us for the mistake to upgrade the design for snow load and bringing out-of-state installers to build the room during the freezing cold months. They also threaten to put a lien on our property when asked three times verbally and twice in writing for the COO from the county inspector before we would pay the final 10%. For this and several other details, we could not recommend the Denver region to anyone. I will say the room addition is a very good product — very good design.

very professional and polite.

If I could give you a -10 I would. Quality of windows is terrible-double hung windows don’t seal-and the solution is weather stripping. One window has been replaced twice in 3 years. Broke siding on house at install and did not tell, I discovered later. It takes months for service to respond. I can NEVER get a hold of a live person in Denver. Have had nothing but issues for 3years and no one there cares. I am sure no one will reach out after reading this either. I have pages of documentation of all the issues. I tell everyone I know NOT to use Champion.

Only if they ask.

Will know more after we have had them for awhile but they are beautiful windows

Overall very professional

The install, quality, and sale was great. They gave us a pretty large window of several months between sale and install. It definitely came within the last week or two of that window but, it was within the window. I just wouldn’t recommend to anyone who is in a hurry or lacks patience.

Currently it is difficult to close the door so that it latches. Have to pull hard and knob

Expensive but good quality

Putting our home on market being delayed.

My experience with Champion Windows has been the worst I have ever had with a company. This project has now extended well beyond a year, despite the original contract signed on July 5, 2024, which included a verbal guarantee by Christian Valdes that installation would be completed within 6–8 weeks.

After that timeframe passed, I made repeated attempts to contact Champion, starting with Christian Valdes and working my way down the list of contacts that were provided to me: Brooklyn Smith, Luisa Sanchez, Chris Trojan, Ana Hernandez. I never received a response from any of these contacts. I then began calling customer service often multiple times per week, and each time I was told "someone from the Denver office will contact you within 24 hours". I never received a response from the Denver office through November 2024 and absolutely zero communication from Champion. Out of frustration, I filed for my first complaint with GreenSky. I requested to cancel the project but was told I would still be responsible for paying 30% of the contract total if I did so.

Once Green Sky was involved they were able to put me in contact with Scott Lenz. Scott informed me that installation would occur in December 2024—yet again, this deadline passed without follow-through. After ongoing efforts on my part, the initial install took place on February 4, 2025 - all three pieces of glass and one frame were either defective or damaged and needed replacement (I'm not sure why they are not inspected prior to leaving the warehouse as the damage was very noticeable before they were ever installed.) During that visit, Enoch explained all tempered glass used by Champion will be stamped or labeled. The replacement was scheduled for February 20, 2025, yet when I specifically asked if the glass had been inspected prior to installation, I was told it was too dirty to determine and would be cleaned following installation. One cleaned, some of the same defects were clearly visible. Additionally, the glass was not stamped or labeled. After speaking directly with the installers, I discovered that the glass was not a Champion product, but had been sourced locally. Even worse, it was of inferior quality, and did not meet code requirements for the size of the. The originally installed tempered glass—required for safety—was replaced with standard, non-compliant glass.

This alone was extremely concerning, but the problems continued. As of April 2025, one of the windows had cracked and began leaking. I notified Scott and Jared of this issue in April 2025 by email with photos included. Jared then looped Mike Smith into the conversation, at which time I requested a written action plan addressing the outstanding problems, along with a timeline for resolution, which I never received. After repeated follow-ups, I did not get a response from Mike or Scott until June 6, 2025. At this point I had water damage to one of my interior walls, so I once again requested a written action plan and timeline, which I did not receive. Mike Smith Informed me the glass had been received and had been in the warehouse since May 2025, but was waiting for the frame to come in to install all at once. Mike Smith did not acknowledge the water leak or take any accountability for Champion's complete failure up to this point and never did provide an action plan or timeline for repair. Fast forward to November 2025, I am finally contacted for the new frame and glass installation. Installation was scheduled for November 12, 2025. When the install team arrives I ask them to inspect the glass prior to install, in which they again find one pane is defective. They decide to install the two they have, but immediately noticed the water damage (which I had informed Mike Smith and Jared Lenz in April 2025) and acknowledge the frame is damaged and need to be replaced. One pane of glass is installed.

Finally January 8, 2026 both pieces of glass and two frames are installed. Unfortunately, due to weather they were not able to fix the mess the original install team left (caulk smeared into my siding, damage to the trim and silicone spots on the windows). Andrew has been in contact and is planning to address these issues next week. Paco and team were very professional, courteous and very detail oriented. I would say the only to bright spot of this awful Champion experience came in January 2026 when working with Amy McGowan and Paco and his team. If they had been involved from the start all of this most likely would have been resolved a year ago.

I have a chain of 30+ emails if you're interested in viewing the lack of response, accountability and acknowledgment your management team provides.

If any of you had a similar experience with a company, would you recommend them to anyone?? A year and a half to install three windows, after I was sold on a 6 - 8 week install by your sales rep...... The amount of my time that was wasted trying to get Champion to fulfill their end of the contract is absolutely ridiculous. I will tell everyone to seek other options and run from Champion Windows!

Good customer service

We had a communication disconnect once our main windows were installed. They needed to remeaaure for our sliding doors and contact us when they were in. But we had to go down every avenue just to get someone to talk to respond back to us. It was poor customer service. We did however get it settled and worked out, but we shouldn’t have had to do that at all.

The project was completed within a month of signing the contract.

Champion Windows consistently delivered professional services throughout the entire project, from initial consultation to final installation. The installation team was highly skilled and efficient, completing the work quickly in a clean and organized manner, demonstrating a high level of professionalism and respect for our property. The windows themselves are incredibly impressive, eliminating drafts, providing increased sun protection and helping with energy efficiency.

I would never ever recommend Champion Windows to anyone. Their shady sales tactics are the most deceitful I have experienced in my 50+ years on this earth. The windows are not of the quality they purport to deliver, and are incredibly overpriced. Their online and radio marketing is a complete lie - "buy two, get two" does not exist. The salesperson even told me the fine print states that you are getting 50% off the cost to make the window, not the retail price. They start you incredibly high and then offer a 40% discount to make you feel like you're getting a deal. But when you do the math, they are still 1.5x to 2x comparable windows. There is no amount of monthly energy savings that can cover a $20,000 delta. Run from these guys.

Referral for peron who referred you to me has not been provided. Don't see much difference with the new windows and what I had

There were some issues at the time installation. Some of the issues are still not resolved.

2 windows were the wrong size. The installer convinced me to sign a paper saying everything was good. It’s been 2 months and champion has still done nothing to put in the correct sized windows. I have heard nothing. I’m never using this company again.

It took a year to build a sunroom, people made statements that were not factual. An in the process we were asked to add an addendum which added additional cost to the contract for an item was originally discussed with the original salesperson but was not to documented

The initial salesman was great. The installers were professional and did an awesome job. During the installation, however, the project manager/inspector attempted to up sell me 3 times while I was trying to work. Even when I bluntly told him that more windows were not in the budget and told him I didn’t need a quote, he pushed it on me anyway. I know how bad the windows in the house are. I live here. I also can’t stand pushy sales people. He even insisted he wasn’t on the sales team but he was CLEARLY trying to push more windows on me. It was a coin toss between champion and pella at the beginning of the project and I will NOT be returning to champion. I don’t remember the name of the initial sales man(who was awesome) and the rest of the people so I won’t be rating below.

I would not. Left 2 different messages and I have yet to get a call back.
