SIR Home Improvements — A Dedicated Team

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.

SIR Home Improvements has delivered the highest level of customer service since we opened our doors in 1980, as evidenced by our A+ rating with the Better Business Bureau and awards from organizations like Angie’s List and My Home Renovator.
Home remodeling is a major investment, and we understand that homeowners want the assurance of knowing their investment is protected. Many of the top-tier products we offer are backed by lifetime warranties, which we match with unparalleled lifetime labor warranties.
SIR Home Improvements is committed to providing homeowners with the best value per dollar while also fulfilling their home improvement dreams. We live up to our commitment through our selection of top-quality, energy-saving products and our complimentary energy seal program.

A Note from Our Owner – Frank Mumford


I graduated from Western Michigan University with a degree in business. I worked for four years in the home-improvement industry before starting SIR Home Improvements. Since my family didn’t have much money, I had to pay for college myself. I decided my best opportunity was through athletics. I walked on to the football team at Western Michigan University and became a starter earning a four-year scholarship. I believe the challenges in my early life and in college helped prepare me for the challenges I would face in business. I am a licensed builder. I have been a board member of my church for over 15 years. I have been the owner of SIR Home Improvements since its beginning in 1980.

My day-to-day position can be summed up in one word — “service.” I believe I am here to help people at Sir Home Improvement grow and accomplish their personal goals and dreams. It is only through their growth that Sir home improvement has the opportunity to grow. I love my job because there is always something new and exciting to do every day! Our mission statement is “to offer the best value per dollar in order to fulfill our customers home-improvement dreams.” I feel that fulfilling dreams drives me.

I love spending time with my wife and six kids, working on church projects, playing golf and preparing other ways that I can help people in the second half of my life.
