Ken Newman gave us an estimate after walking around and measuring our house. We received four estimates--one was remarkably high (Gutter Helmet/Mr. Fix-it), one was low but didn't have solid gutter covers, the other two were pretty close (including Carefree Gutter Guard's). We went with Carefree because of the lifetime guarantee and the solid reviews on Angie's List. Carefree also gave us references--names and numbers of other users in our neighborhood. I spoke to several of them and the reviews were all positive. There were some scheduling delays due to back-ordered parts but once the crew got here they did great work. Mike and Josh, aided by the salesman Ken, did fast work and were very professional. They kept the place clean, worked really hard, and were excellent about addressing my questions and concerns. There were a few complicated spots and they explained the options, made recommendations, and we decided on the best course. Although we haven't had much rain since then, during our only solid rain I went outside with an umbrella and watched the gutters perform. They worked great. We needed one minor adjustment so I emailed Ken. He came to our house within the hour and did the work personally. Solved the problem completely. I am very pleased with the product and value. The sales pitch was low pressure, the work was done very well, and I'm happy with the gutters. Based on the reviews and the history of success from current owners, I expect these gutters to perform very well for many years. I'm also sure that if we ever have any problems or concerns, they will be addressed quickly and effectively.
