We build beautiful homes to last a lifetime.
Proudly serving south central Pennsylvania since 1978, J. W. Mumper Construction specializes in designing and building high-quality custom homes. Jim Mumper and his experienced staff and carpenters look forward to working with you to create the home of your dreams.
We will work closely with you to design a beautiful home to fit your needs and lifestyle. Every aspect of the home is completely custom, from the layout to the colors of the light switches. We love incorporating personal details like beams from an old house, an unusual tree trunk as a handrail, or an instrument display case.
We are committed to building high-quality homes, which start with quality materials, including poured foundation walls, custom cabinetry, custom moldings, Andersen windows, 2x6 exterior walls (for better insulation), framed 16 inches on center.
From the position of natural light to foot traffic patterns in your home, we carefully consider every detail, to build a beautiful, comfortable, and livable home.
At Mumper Construction, we include allowances that will allow you to purchase quality materials.
Our company provides ongoing support long after your home is complete. Just call us if you ever have a question regarding materials or anything else related to the original construction.
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.
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.
Jim, and his team of subcontractors, are honest, trustworthy and their craftsmanship is unmatched. They pay attention to small details, while always keeping the larger picture in mind. The entire team takes great pride in their work. Mumper Construction has helped us transform our house into a home.
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.
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, his employees, and his subcontractors were professional and made our lives so easy. Needless to say, the quality of workmanship was stellar. Over the course of 14 years we never had a problem. Many friends told us that building could be a challenge and to think twice about it. Not true!
Over the years, we have had many remodeling projects, some major, some smaller. We always call Jim Mumper for his suggestions and we appreciate that he is willing to consider our thoughts also. Jim’s pricing is fair and his employees and sub contractors are capable and friendly. We highly recommend Jim Mumper Construction.
The new construction, renovation and, most impressively, the integration were of the highest quality with meticulous attention to detail. The staff of Mumper Construction was always available, responsive and professional. Add their superior integrity and they have earned our highest recommendation.
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.
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.
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.
