Larry took just over an hour to measure for 10 window replacements and explained the Lead Testing, Torrance regulations, details of the windows we will be receiving, and the process of when to expect the windows.

Ivan and Rolando were the best! Very nice and friendly. They told us what was going to happen .We has a window put in the kitchen. They kept everything neat and you wouldn't know they were there! I would call them again!

They were all incredibly kind and respectful of not only my wife and I, but of my house as well. After they finished, it was as if they were never here (except for the fantastic new windows). As for their work, it is flawless. We got our entire house's windows replaced (about 30-ish windows), and every single last one is perfect. A huge thank you to Edgar and his team!

Ron SharpLocal Guide · 20 reviewsiTotal number of Google reviews Ron has written across all businesses on Google Maps, not just this one.
My uncle is 93 years old and lives in Glendora California. I was talking with him on the phone the other day and he told me he was getting two side windows, one on each side of his big picture window in the front of the house and a new front door which consists of actually two doors because it’s a double door entry. He told me for the two windows and the wood double doors that he is paying $28,000. I just about had a heart attack. I said these guys are rip off artists they advertise on TV far too much and too many other advertisements. That’s one of the reasons their prices is extremely high. There is far better prices out there than what he is paying for this job. Unfortunately, he’s already signed a contract with them and has given them $9000 down payment. What a shame these people are taking advantage of elderly people and charging extremely high prices. I mean you have to understand he bought that house back in the 70s he’s paying more for the front door and two windows and he paid for the whole house. This is absolutely ridiculous and absurd. There should be laws against people like renewal by Anderson taking advantage of people. I’m extremely disappointed in this window company and would highly recommend that anybody looking for windows or doors shop around do not use these high price firms that think their holier than thou and charging extremely high prices. Thank you for reading my article. I never post this kind of stuff, but this is ridiculous

It was a pleasure meeting with Larry for five hours. He was very informative and answered all of our questions and concerns. We are confident that Renewal by Anderson is the right choice. Artemis & Lee Feldman
