We understand that it’s more than just a house we’re building, it’s your home.  We take the time to get to know you and work with you to design a custom home to match your unique lifestyle.

Whether you already have house plans or just have ideas, we can turn your dreams into reality. We can design a home from scratch based on your ideas, or we can build a home from plans you’ve had designed by an architect or purchased from a house plan service.

If you need help finding a lot to build on, we can help you to find just the right location for your needs.

Communication and comfort-level with your builder is critical. Jim Mumper will work with you one-on-one to will guide you through every step of the process and ensure that everything runs smoothly. Jim is a hands-on builder; he is on-site and in the field daily, with an office support staff at his fingertips to relay and implement all information at a moment’s notice. Jim and the rest of our staff are responsive, friendly, and accessible.

J. W. Mumper Construction, Inc. has built a reputation of having an unwavering commitment to quality workmanship, high integrity, professionalism, and responsiveness to customers. Over our more than 40 years in business, many of our customers have returned to us to finish basements, add a sunroom, and even build a second home as their needs have changed. We have also had the pleasure of building homes for some of our customer’s children.

Our company provides ongoing support long after the home is complete. Just call us if you ever have a question regarding materials used, or anything else related to the original construction.

As first time home builders twenty three years ago, Andy and I feel fortunate that Jim Mumper and his office staff and crew walked us through the process. We could not have been happier with our first custom home.  Over the years, Jim and his employees have continued to help us with additions of a wine room, outdoor fireplace and more recently an addition of a first floor master suite.

Jim and his staff developed a home designed that met all my needs and also all ADA requirements including passing a VA final inspection after the home was built. Mumper Construction did an excellent job! People who have been to my home don’t even realize that my custom home is much different than other custom homes due to Mumper’s designed.

We enjoyed working with Jim and his entire team from start to finish. They all went out of their way to work with us on the special custom details and wood work that makes our home unique and beautiful.

Jim’s attention to detail, extensive knowledge, and integrity beyond reproach, made it a no-brainer to select JW Mumper Construction to build our home. Once selected, through Jim’s leading, we only had two meetings, beautifully built home on budget, time, and ZERO ISSUES! I can’t recommend Jim enough or fast enough when someone inquires on new build or remodel.

J.W. Mumper Construction is breath of fresh air. Honest, open and always willing to listen, Jim Mumper and his team will deliver what you ask for and what they promise. If Jim shakes your hand, it’s a done deal.

- Tom and Tina Schimmer

Jim is honest and does quality work and we will always call JW Mumper Construction for any future home project. Jim and his team are a pleasure to work with and we cannot recommend them highly enough.

In 1989 we signed a contract with Jim to build our home in Green Lane Manor. He said to us, “Have fun with this, there will be problems, but we will work them out”.  That was the start of a friendship that has lasted over 30 years.
