Vantage Windows was professional, knowledgeable, and transparent from the very beginning. The…read morerepresentative who met with us was courteous, informative, and took the time to clearly explain the process, answer questions, and walk through options without pressure. What stood out most was how organized and straightforward the experience felt. Communication was clear, information was provided openly, and there was never a moment where we felt rushed or uneasy. It was obvious we were dealing with a company that knows its business and takes customer trust seriously. If you're someone who values professionalism, clarity, and a company that shows up prepared and respectful, Vantage Windows delivers exactly that. We appreciated the experience and would absolutely feel comfortable moving forward with them.

I see why you have a strange name, adding 'The' to your name, which adding 'the' does not come up as a licensed business. When I searched this site without 'the' (see pic) its expired. So, you can see I did my research. Let's add when I googled the website on the card, it showed a company out of state. However, I see it today at the very end. Funny. Quick move on your part to add it. In any event, your sales person showed me a flash of a license, but I leaned in and saw it was for another company. Looked like you were hiding something which in turn leads me to believe you're a liar and don't have your business sh!t together, so I will not do business with you or any company remotely related to you. These are my feelings and opinions. First Review: A solicitor for 'Vantage Windows' discussed getting a quote for me. But when she left I checked their license as of 12-16-2025 their license has expired and are not allowed to contract for business. Additionally, I found out there is no company open in California. Hmm.

My split level house is 27 years old, and three of the four levels have original contractor grade…read morewindows. 3 or 4 years ago Renewal by Anderson replaced two windows and a slider door. While I think they did a good job and I like their products, they were super expensive and I still had 14 more windows that needed to be replaced. In May of this year I started to seriously consider getting the rest replaced. Enter Alpine Exteriors. They provided the third bid and landed in the middle price wise. They were considerably less expensive than Champion (no surprise) and slightly more expensive than a no name company that came out selling cheap quality windows. But Alpine Exteriors quality, service, and selection really stood out. I met with the owner, Hiram Molloy, at my home and there was zero sales pressure and no games. He has access to a number of different windows at all different price points, so he was able to find something in my budget and a quality I was happy with. They were installed a couple weeks ago and that was the real test. I'm pretty OCD and I want perfection. I'm never fully satisfied because that would be impossible, but the installers did a nice job. They were friendly and detail oriented. I asked a lot of questions and spent a fair amount of time watching the install and they were courteous and obviously knew what they were doing. They also cleaned up the mess and used preventative measures around my furniture to keep the mess at a minimum. Upon final cleanup they collected all the stickers from the windows and placed them on copy paper so I could apply for the rebate. Hiram followed through on his promise and mailed me all the rebate paperwork with instructions. If you are looking for a quality window company that offers a competitive price and does what they say they are going to do, look no further than Alpine Exteriors.

I made the mistake of signing with someone who rang my doorbell and reminded me of how old and…read moreawful our windows were, and they needed to be replaced. I think I did it out of guilt, but the next day felt terrible. Fortunately, I was able to void the contract and do a search for a better window company. I found it. Alpine Exteriors was by far the best choice. From start to finish, the process was simple, and we have nine great new windows! When we can afford to do the rest, we will definitely go with Hiram Molloy and Alpine Exteriors again.

Well, I'm not used to door to door salesmen, so I'm naive to their gimmicks. Here's what I've…read moregathered. First, the salespeople I spoke with were all very nice. Essentially, they said they were coming to the neighborhood to offer a special deal for just a couple of houses, to update their windows as "model homes" where they give you a bangin' deal in exchange for some advertising (have a sign in the yard for 60 days, write a positive review, allow before/after photos, and share the amount of energy savings after a year of having the new windows). They would cover labor costs, installation, and discount the windows themselves 30%. The first guy took down my number because I said I wanted my husband home before they started taking measurements to give me a quote, and he called later saying the two slots had been filled. The next day or a couple of days later, another guy came to the door saying behold! We opened another spot! So we made an evening appt for another sales person to come and do the measurements. She came, explained their windows, the deal, the lifetime warranty, etc and I have to say, she was very kind and accommodating when it came to our 1.5 year old son and newborn who were vying for attention. But she opened with "I'll need a hard yes or a hard no by the end of this conversation, and my husband hates pressure tactics, so he was already skeptical. Long story short, their "super discounted price" was $45,000. Full price was nearly $92k. I don't think windows should be ~20% the value of our house, sorry. Anyway - we ended up giving a hard no, and I read online that this company gives the same spiel to everyone. There is no model home. I'm guessing their five star reviews are part of the "discounted" exchange. I'm glad my husband is not as easily duped as I! When the time comes for new windows, we will look elsewhere.

Extremely disrespectful and unprofessional I have one large,…read moreclearly visible "NO SOLICITING" signs at the front of my house (one in the front yard and one small, right on my front door). Most people respect this, but a representative from this window company ( PERFORMANCE WINDOWS) totally ignored them and rang my doorbell anyway. I was feeling sick and resting, and only answered because I thought it was an emergency. When I asked him to stop and pointed out the signs, he admitted he saw them but kept pushing his sales pitch about a "30% off promotion." When I declined again, he aggressively questioned why I wasn't interested, making me feel incredibly uncomfortable and cornered in my own home. This company clearly does not train its staff to respect boundaries or homeowners' privacy.

Called my glass guy in California and he said that it was a special fix and that I would have to get the parts from Knapheide and he would install it for $75. So I called Knapheide. They wanted $129.99 for the 9x30 window, outer seal was $11.99 per foot, inner seal $9.99 per foot with a minimum 8 feet each must be purchased. So I was looking at $380.83 without shipping and taxes. I was still far away from home so I decided to give Glass Doctor of Utah County a shot. They were able to fix everything for $239.40 before taxes saving me at least $140. They were super professional and friendly and the person that did my window had over 30 years of experience.

Short version: I…read morerecently had my car's windshield replaced at Glass Doctor in American Fork. It was, bluntly, a TERRIBLE experience. The new windshield cracked in less than two weeks while the car simply sat in my driveway. In spite of all signs pointing towards a manufacturing flaw or installation mistake, Glass Doctor insisted it couldn't be their fault and wanted $150 to replace it (the original job cost $360). When I pushed back, they acted like I was the problem (rather than the failed windshield) and made it clear they had no desire to earn my trust or continued business. Unless you want that kind of grief in your life, I'd strongly recommend taking your business somewhere else. Long version: After the replacement, my car sat in my driveway for 2 weeks (I use a different car for around-the-town driving). Sometime in those 2 weeks, the new windshield cracked. Googling the issue yielded the likely cause of a "stress crack", which are "cracks that appear without visible signs of impact, often starting from the edge of the windshield" and noted that the common causes include "manufacturing defects or poor installation." That fit the circumstances perfectly: no signs of impact at all (and it would be quite the feat to get hit with a rock sitting in the driveway), crack started from the edge, and shortly after installation. When I called Glass Doctor, their attitude could best be described as "that sucks for you." They insisted that replacing it would cost $150 under the terms of their warranty, no matter the cause and in spite of the fact that they could offer no explanation for why it had cracked so quickly. Unsatisfied, I asked to speak with the owner. When she called me, I explained that, in my viewpoint, all signs pointed to either a bad part or an error in the installation. I explained that this should be a "we're so sorry, give us another chance to earn your trust" situation, not a "you can roll the dice again for another $150" situation. She proceeded to accuse me of "bad mouthing" her installer and her company for suggesting that the installer could have made a mistake, because "he's one of the top 20 in the nation." She said I was "bullying" her for being honest that I intended to share my experience, good or bad, in an online review. She insinuated that I was lying about the car not being used, despite my offering to bring in a statement of work from my mechanic showing the mileage the last time it was serviced to prove it. She made it clear that earning my trust and future business wasn't important to her. She insisted it couldn't be a stress crack because they "usually run horizontal" (I couldn't find anything online to support the idea that stress cracks run horizontal). She absolutely would NOT acknowledge that they could have made a mistake. She finally agreed to replace the windshield free of charge ONLY after making it clear that she would never do business with me again (who would want to do business with the company after this anyway?!?) After they replaced the windshield again, I asked if the technician could identify the cause of the crack. She said: "He said it could be a stress crack, but they usually run horizontal. So, no explanation for it. Maybe it was a small rock." Yeah, a small rock that hit a car in a driveway in a residential neighborhood, struck right at the bottom edge of the windshield (where the hood rises up to protect it) and left no signs of impact, yet caused a 10 inch crack almost immediately. Even when ALL INDICATIONS pointed to a stress crack, they preferred to ignore the facts, even when that required them to assume I was lying. They'd rather blacklist you than admit they could've made a mistake and attempt to make it right. This is not the kind of business I would trust. Take my experience as a cautionary tale.
