We first heard about Renewal by Anderson at our local Walmart. The associate was very friendly and I though, sure, it's a quote, why not. It's good for a year he said. Fast forward... We had a bad experience before even talking to anyone about an estimate. First off, I wrote my name clearly on they form at Walmart and when I received the email my name was butchered, which shows lack of detail attention. Secondly, we set aside time in our home and family to have someone set up an estimate with us. Nobody showed up. Afterwards we got a notification from our doorbell that someone was at our door. In the video you can see a woman walking up our stairs just a couple steps. She stops, looks at our door, walks back down, stands at our outside door (which was wide open and welcoming into our porch), then proceeds to leave. That shows just how (un)willing their staff is to meet with potential customers and put an effort into meeting people and making a sale. I have never been so disappointed with a company, especially before even getting a chance to talk with anyone about business. Afterwards I was looking at reviews and I read they are way overpriced and not a good company to work with. I would have to agree on the not a good company part from our experience.

I own a 2 family, in Watervliet. Since I purchased the home, in 2003, I have had all 32 windows replaced; by Anderson Windows. I have a large bedroom window; that is out of alignment. I called Anderson on September 22nd; and left a message requesting a call back - no response. I left a 2nd request on October 20 - still no response. This is NOT a reliable company.

This company is very agressive. They scam you with e-mails and do not accept unsubscribe. Actually I never even subscribed, but still the advertising is overwhelming. A quick research online says that this is a huge problem for them, as they do not send everything themself. However the scam e mails are directly attached to their offerings, making me suspect they are behind all the false domains as well. This has been lasting for years and they are not putting in any effort into stopping it. The only thing that can stop it is consumer power - find another vendor. At least - read the reviews of them before making any agreement, plenty of reviews here says the same - "I wish a read the reviews before signing a contract". That tells a lot.

I am so beyond annoyed. Whoever your River Falls Wi door to door to door person is, you need to have a talk with them. I’m a night shift worker in healthcare. I turn my doorbell off and only have it chime outdoors while I sleep. Your salesman should NOT be pounding on my door so hard that it literally shakes my entire upstairs bedroom and sends me running downstairs like my house is on fire. If no one comes to the door MOVE ALONG!

Extremely Overpriced and Unimpressive Products With extensive professional experience in construction, building materials, and custom fabrication, I was thoroughly disappointed with Renewal by Andersen. After evaluating their products and obtaining estimates from several premium window manufacturers, including Marvin and Pella, I found Renewal by Andersen’s pricing extraordinarily difficult to justify. Both Marvin and Pella offered significantly more competitive pricing, even with professional installation included, without compromising on the quality one would expect from premium window manufacturers. The sales presentation was equally disappointing. The representative who visited my home demonstrated surprisingly limited knowledge of the technical specifications of the products he was selling. To make matters worse, the window sample he brought was poorly functioning — hardly an impressive demonstration of a supposedly high-end product. Ultimately, I purchased German-made European tilt-and-turn windows for my entire house. The quality, engineering, functionality, and overall value were substantially more impressive, at a considerably more reasonable price than Renewal by Andersen had quoted. In my opinion, Renewal by Andersen relies far too heavily on premium pricing without demonstrating the corresponding level of product quality, technical sophistication, or value. I strongly encourage anyone considering their windows to explore alternatives, particularly Marvin, Pella, and European window manufacturers, before committing to such an expensive purchase. A premium price does not automatically make a premium product.

Worst company imaginable to work with. Our windows and sliding glass door were installed in July 1 2026, it's now October, 3 months later and they're still not done. Our kitchen window doesn't seal, it shifts back and forth. We are supposed to have a threshold for the sliding glass door, has never been installed. Every time we call we get no answers. Their customer service says they'll let the project manager know and we've never heard from him. Overpriced for what you get. DO NOT expect to get quality from this company.

Every day, this OVERLY LONG advert for this Window company make me violent. That women's voice alone is absolutely irriating, like a combo of overly enthusiastic and patronizing at the same time. To add insult to injury, they add multiple door bell ring sounds to the commercial, which sets my dog off barking each time. Companies that use doorbell or phone ring sounds in their commercials, deserve to meet up with Chapter 11. Based on reviews who have actually used their service, I'd say, stay away.
