Guardian Windows & Siding Inc. BBB Business Review

Google Review:

“I went with Guardian because of super reviews on Angie's List. I could not have been happier. This company has low overhead (as opposed to big companies like Andersen with inflated costs) and is owned by Marty. He personally visited my house and explained the way his windows are constructed then gave me what I considered a very fair estimate of the cost to replace 45 windows in my house. I was very pleased with the windows that were delivered but, in addition, the installation crew was the best. Headed by Fernando, Dee, Matt, Daryl, Jim and Harry were very considerate, polite, informative and very conscientious about our house and furnishings. They covered everything removing all glass and other debris even vacuuming. These guys were excellent and I can't say enough. If you go with Guardian, you are getting not only an excellent product at a fair price, you are also getting great craftsmen who take great pride in their work...a rare thing these days.”
