Mike Schmidt is an incredibly professional businessman, who provides quality service, incredible work and a great product, in whatever range you need. We had received an astronomical quote from a national remodel chain, and when Mike came by, he took a look at our windows, and asked what I wanted. I told him a good, middle of the road vinyl window with vinyl welded corners. He told me right there the estimated price, he wrote up the estimate, gave a down payment, and he had them installed within weeks. No BS sales pitch, all on his good name, and a hand shake. THIS is how business should be done. As Mike said, and I paraphrase “I have been doing this for 20+ years, and my name is on the business. I can’t afford to do a bad job”.
