We really enjoyed working with all the folks at Performance Windows: the appointment scheduler who knocked on our door, our salesman, the window measurer, and the install team. They have all been great!! We also LOVE the windows. They are so beautiful! They are easy to open/close and they block sound great! Our only regret is not replacing ALL the windows in our house. The Performance Windows not only function wonderfully but they give the house an upgraded look. We highly recommend Performance Windows. read more

So far, so good! I'd been wanting new windows for a while when Performance Windows stopped by our house. While I don't love to usually entertain solicitors, they caught me on a good day. Amari was friendly and patient, walking us through the different options and offerings. I was sold! This was the third window quote I'd received, and I really appreciated the straightforward pricing and easy financing options. It took about three months from our initial meeting to installation. On install day, it was super cold and the crew worked efficiently, cleaned up quickly, and communicated well throughout the process. The supervisors kept us informed of their progress and were happy to answer any questions. It's only been a few days, but we haven't had any issues so far. I'd definitely recommend talking to Performance Windows if you're considering a window replacement. read more

BEWARE, this whole "advertising home" thing is a massive scam. Someone came to our home telling us we had been selected as one of two rare advertising homes and said someone would follow up with more info. The pitch was that if we had windows installed and put their sign up in the yard and left them good reviews they would give us 50% off the price of windows and free install. The "marketing coordinator" (salesperson) who came for the follow up informational meeting tried to take advantage of the fact we hadn't done any advanced research (since we weren't actively seeking out quoted for new window, which she knew) and tried to convince us pella/anderson windows for our home would be $75k and so performance windows at $35k were a screaming bargain. This was not an informational meeting, it was a bait and switch sales move. She told us that we had to sign on the spot and drop half the amount ($17k) otherwise when she walked out the door the deal was gone. She was trying to pass completely made up inflated numbers as fake "competitor pricing" in order to make her offer look like a discount so we would fall for the exploding offer. Thank god for chatGPT. A few questions quickly returned a realistic estimate for windows for our home ($18-20k for vinyl windows, not $35k) and explained the whole advertising home scheme, allowing us to call her bluff and decline the so called "deal". I would never do business with a company that uses pressure tactics and preys on unassuming folks who haven't done their research in order to lock in contracts under false pretenses. I hope everyone sees this review before they sign up to be an advertising home or even waste an hour of their precious time talking to Performance Windows sales people. read more

Performance Windows - Salesman ring doorbell with three no solicitors signs - Windows Installation Near Me - Broomfield, Colorado

Scheduled the appointment 3 days prior and never showed up. Poor customer service! Look for professionals not someone who's looking for money read more

After a solicitor came by offering us a deal, that just two houses in the neighborhood would be selected for, urging a speedy decision we decided to move forward with replacing our windows. They were 20 years old and their age was evident. The windows arrived about 7 weeks later, within the expected timeframe. The installers arrived on a Saturday morning at 8:30am with the expectation that they would namely be able to replace all 26 windows before the day was over. The team worked hard and long they ended up working until 9pm. The first several windows were installed professionally and well but as time went on and the sunlight was fading the craftsmanship deteriorated. I'm not sure if it's because the crew could no longer see what they were doing or if they were exhausted but the caulking around the windows was lumpy/bumpy and just straight up messy looking. Additionally, the screens which were made on site were not well done. A quality screen should be taut not loose. Most of the screens are loose and flimsy. Honestly, I feel like my 20 year-old screens were of better quality. We expressed our concerns to the manager when he did a follow up visit after the installation. After taking a look, he agreed about the quality of the screens and caulking and promised they would come back out. The Saturday they were supposed to come out at 10 AM to redo all the screens and the caulking and clean up some foam that had stained our patio and by 11 o'clock no one has showed and the manager is non-responsive. Updated Review: The crew ended up coming back out 2 more times to fix the exterior and interior caulking. It was definitely not convenient but they did come through on their end. While the process with the company was not ideal they did come back and ended up remedying the situation. read more

We had 4 windows replaced today and I'm so impressed. The workers were so nice, cleaned up meticulously, color matched paint to make a seamless install, and made sure I loved the windows in every aspect. My house is so much quieter, no dust coming in and on top of that they are BEAUTIFUL. So happy with the entire process from the first appointment with a sales rep to the workers leaving I highly recommend Performance Windows. read more

Great window replacements for my old builder-grade aluminum windows. The installers were very fast and did a great job of the installation, and a very nice cleanup too. A lifetime warranty makes me feel great about the product, too. It's getting colder at night, and our home feels quite a bit warmer; looking forward to saving on heating costs. read more

Salesman ignored our LARGE no soliciting sign right by the door and knocked anyway. Proceeded to tell me that since 'we had a nice house and it was at the entrance to the neighborhood they would give us 50% off.' Became pushy when I said we'd already gotten quotes and weren't interested. When they kept pushing I pointed out the sign and they turned around and walked away. read more

I am very happy with my high-quality windows from Performance Windows. The temperature in my house has stabilized throughout the house AND I only had half of the windows done (so far). And that is another plus in their favor. When the sales ladies came, and we got done to how much the windows would be for the whole house, I flat out said, I can't do that. I'm on a fixed income. So we came up with a plan to do half of them now and the price I got is guaranteed for 3 years so I can come back in a year and do the rest of the house. The new windows were installed in a few weeks rather than a few months. They brighten the front of house and make it look so fresh. Thank you so much for the customer service and new windows. read more

Performance Windows are quite beautiful. I immediately noticed the noise cancellation, and when it snow again the windows kept out the cold in the basement the old metal windows allowed in. The crew they sent were professional, quick, and very efficient! Nancy read more

Our original windows were deteriorating rapidly and some were dysfunctional or merely pictures windows (I.e., aesthetic vs. able to be opened for fresh air). We were at our wits' end when a representative from Performance Windows happened to drop by to offer a promotion so we scheduled an assessment and received a competitive estimate with the condition they could post a sign and advertise the final product. We agreed to this stipulation and everything went smoothly from that point forward. The staff we interacted with were transparent, respectful, and efficient. The pricing remained the same once we had official measurements and placed our order. Windows came in before the promised date and installation was scheduled quickly from there. The installers were prompt and respectful of the home. They offered to touch up paint on the exterior trim - even where the installation wasn't responsible for the missing paint just to be sure we were happy with their work. Since then, we have been so pleased with the quality of the windows and the care with which the team completed this installation. We just had a follow-up visit where they reviewed our lifetime warranty and made sure we were happy with everything (which we were). We are thrilled with this company and the ease of the process from start to finish. We recommend this without hesitation. read more

The entire process from selection to installation was seamless. The windows are beautiful and the quality is exceptional.

Came to my door, with a no soliciting sign, very clearly hanging on the doorbell, in the middle of the day, rang the doorbell three times while I was trying work. Then insisted it was OK that she rang the doorbell because our windows were old. When she was told they were not old, she continued to argue that I didn't know how old they were, even though we built the house less than 10 years ago. Told us the neighborhood was older than that and we had no idea even if I needed new windows I would never use a company that uses a sales person like this. read more

Incredibly unprofessional experience. They made us promises then demanded to cancel our deal. Badly handled. I would not recommended working with them. read more

Yep, they still repeatedly ring the bells and knock super hard on doors with very clear No Soliciting signs. Guys name was Kyle and he was a shameful representation of this company... I'd never do business with someone who hired such an a$$hole of a solicitor. read more

Installation was no-hassle, they did a great job and the quality of the windows are excellent

Windows installed. Fit and work great! Caulking looks like it was done by a kindergartener. Horrible look. Waiting for 3rd screen door to be installed on patio door. It has been in for weeks, but lack of calling to tell me it was in. I enquired about it. No showed today's appointment to install and fix caulking. Very disappointed with the lack of follow up after installation, so they are not fulfilling their promises for warranty issues. read more

We have had a great experience with the team at Performance windows. Nick and Casey on the sales team were the first connection we had and they were fantastic about providing detail about the quality of the windows as well as the lifetime warranty and the ability to pass that warranty on if we sell in the first 20 years. They were flexible in meeting our needs and helping us find replacements that were in our budget and at a much better price than competitors. They delivered our windows in less time than originally planned and they replaced our windows in a day with an excellent team led by Jose. Jose was professional and treated us and his team with incredible respect - they even let us slightly alter the order of which windows went in first so our kids could play in their toy room. The quality of the work is superb. We had hired another company to replace a couple of other windows about 4 years ago. They are fine, but not quite the same quality and their finish work was not very good. Jose's team did the work quickly and made the finish work look as good as it did when they started. We had some very cold nights immediately after they installed the windows and they have been incredible. No more feeling the drafts of air coming from the windows! I'll also mention that we had a miscommunication regarding one of the windows. Josh took the time to talk through the situation to make it right. I could tell that he wasn't looking for who to blame, but how to make his team better. It was very refreshing and professional. Our experience has been incredible with the upmost professionalism from day one. We highly recommend the Performance Windows team! read more

My new windows look great. The install was quick. I plan to recommend these to my friends.

Please don't be fooled. A fella came by because they were ramping up a marketing effort in my area, in the next few weeks. He came by my 4 year house, which has triple pane, German tilt-turn windows. These windows are used in net zero homes like mine. He told me his windows have more technology in them. I guess I'm hung up on the fact that he called my 4 year old windows, old. Haha. Hey performance, you should ramp up your sales efforts read more

The process was simple from start to finish and the window is great. We will use them again in the future.

Horrible sales experience. Pushy door to door unwanted soliciting and arguing with us about their approach. Dont do business with these jerks. read more

When looking for windows we were not sure who to go with. We decided to try performance windows. So far we have noticed the air conditioning is staying within the home making it cooler for all of us. Now we could not replace all the windows do to our cost but with the ones we did replace we have noticed an improvement. The job was done within one day! We team was professional and there was a small cleanup we had to do after them. Mostly from dirty hands and dust. But that was to be expected. read more

Performance Windows - This is one of the few we got replaced looks amazing - Windows Installation Near Me - Broomfield, Colorado

I wouldn't ever contract with a company that either couldn't read or couldn't abide by my "No Soliciting" sign. Tried to escalate to the local office where they ignored me. Same with corporate office. Just crummy people all around. Pretty sure there's also an aspect of it that is also a pyramid scheme because each of the four people who came to my door was a 22 year old "Marketing Director" or "Entrepeneur". read more

I received my performance windows today and I couldn't be happier. Not only are they of a higher quality than my previous windows, I can already tell that the outdoor noise is significantly reduced. A very busy I70 is at the end of my street, so traffic noise is constant. I am enjoying the quiet. The installation team was efficient, professional and great to work with. I work from home and they were very aware of my time and the noise. They answered all my questions with clarity and clear knowledge of the product they were installing. When they were done they left my house cleaner than when they arrived. My entire experience (from the sales team to installation) with Performance Windows has been so great that I would recommend them to anyone. read more

If I could give negative stars, I would. Rod Woolley came to my house to discuss options for getting my windows updated as part of an advertising campaign. I was interested, so we scheduled an appointment two days later. I shifted a lot of my schedule around to make the appointment time work, but my wife was not going to be present as she was taking care of our two small kids during spring break. I communicated this to them and that we discussed between ourselves what we wanted to ask during the appointment. Rod texted stating that we both needed to be present and that maybe it would be best to reschedule. I confirmed that it would only be possible for myself to be there and that we would be prepared to make a decision by the end of the appointment. My appointment time came and went with nobody showing up. When I asked if they were on their way, Rod informed me then that we were forced to reschedule due to the inability for my wife to be present, without telling me that the appointment had been cancelled and nobody was coming. It was "company policy" that we both had to be there. It is completely unacceptable to demand that my wife must be present. You cannot force our schedule, and impose how you think our partnership is allowed to make decisions. Ignoring the fact that I'm the sole person on the mortgage and the title of the house. I will never do business with this company. Thank you for wasting our time and making me miss work for nothing. read more

Ignored my no soliciting sign and dove right into a high pressured pitch about using our house as a model for promotion/advertising. It looks like they've also disabled Google reviews. Stay away. read more

This company apparently does not care about trespassing on people's property. When asked if they can read the no soliciting signs they stated the signs don't apply to them. They have been upsetting a lot of people in our neighborhood due to ignoring the no soliciting signs. Even saw ring camera video of one of them trying to open someone's door. I can't imagine any professional company conducting themselves in such a manner. Would NEVER use them due to the way the salesmen have been treating potential clients. read more

We have had a very positive experience with Performance Windows. During the 3 days of installation which included 46 windows, George and his team were extremely organized and every person knew what their job was for the installation of our new windows. At the end of the day everything was cleaned up and ready for the next day. Great team of installers! We love our new windows! We can feel the difference in the insulation value that the new windows provide. We appreciate that the Performance Windows product was crafted with the needs of Colorado weather in mind. We highly recommend Performance Windows! read more

Jesus and team were absolutely fantastic! The installation was smooth and the windows operate fantastically. Exceptional value and a high quality product. Definitely recommend Performance windows! read more

First, I've got to say these windows are huge upgrade to my previous installation. Immediately I could tell the windows are much better insulated and are better at soundproofing the house. I no longer feel the cold radiate off the windows and I no longer feel a chill throughout the house. They did amazing job, installing 10 windows and one patio door. Very pleased with the insulation work they did, and the superior caulking job applied to the windows. They completely cleaned up the house and hauled away all the old debris and made sure everything wasn't working order before they left. Outstanding! read more

Overall my experience with Performance Windows was great. I have had the windows for a month now and noticed a reduction in outside noise and how often my air conditioner turns on. I opted to have triple pane windows installed in the front of the house to reduce street noise and based on the cost difference I feel that it has been worth it. My only gripes are on the installation. The trim that was installed around the new windows is a tan color (primer most likely) and seems out of place. I now need to paint the trim to match the windows, which I wasn't expecting. Considering the most common window being installed currently is white vinyl, it would make sense to just use a white trim, or at least ask the homeowner before installation. The installation team also didn't caulk over the nail heads on the trim, just another thing I need to do before painting. There is a different crew that installs the windows vs the one that cleans up and some of the light fixture fasteners that needed to be removed during window installation went missing between installation and cleanup. I now have to go find replacement fasteners at Ace hardware. Not terrible but inconvenient for sure. Overall the windows are really nice and have lots of useful features, only time will tell on durability. The reps from Performance Windows have been really great to work with. I removed a star for lack of communication on what the final install would look like and overall final job condition. When paying for new windows/installation, I expected more of a complete service, not a job that I had to finish up behind them. read more

We needed new windows bad, bad, bad. Most were original to the 1957 house. A sales rep shows up at our door and does a great job, she did a rough measure of the windows and we struck a deal. The final measure was no hassle and quick. The windows were ready sooner than expected and again no hassle on scheduling. The install crew called me the morning of and as a courtesy said they were stuck in traffic (they weren't late at all) They dealt with pulling out our old window very easily and they were very patient and courteous with the children and dogs. They were done and gone by 4:30! The windows look amazing. The features are modern and the materials are great. Now we can move forward with our next update. Thanks again read more
