About Us

Raising the bar in the home improvement industry was our goal when we started Sir Home Improvements in 1980. Our mission statement is “to offer the best value per dollar in order to fulfill our customers’ home-improvement dreams”. We have a staff of experienced professionals who understand what it takes to give every home we service a custom solution that will stand the test of time. We strive to improve people’s lives, and that is the heart of our business and the heart of our staff, starting with owner Frank Mumford all the way down. That philosophy has led to our growth from two people at the very beginning to a staff of about 40 people who have served thousands of satisfied home owners over the years. We are proud to work with some of the best manufacturers in the industry, allowing us to guarantee product quality and customer satisfaction. Whether you need windows, roofing, siding, or bathroom remodeling, Sir Home Improvements has the right solution for you.
