My wife and I purchased Gutter Helmet through Costco on 8/14/21 at a cost of $6125. Part of the sales pitch included an annual gutter cleaning. After the first year, our gutters were cleaned as promised. When I attempted to have the gutters cleaned after year two, I was told it would cost $150. Gutter Helmet also claims to have a lifetime performance warranty which guarantees the free flow of water without clogging. Our gutters are clogged. The nearest local dealer wants to charge $150 to clean our gutters. What good is a warranty that is never honored? Gutter Helmet is nothing but scam artists selling snake oil! Don't do it!!!
