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.  I highly recommend Mumper Construction.

In 2007, I have developed physical disabilities that required a home that meets all American Disabilities Act requirements for a wheelchair user.  I met with Jim Mumper and his staff with my plans to build a new custom home that was completely wheelchair accessible. This was not a simple task, due to the requirements of the ADA and also approval of the Veterans Affairs requirements and final inspection.  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.  The home was started on time and finished on time.  Jim and his staff were always available to discuss all or any of my concerns and perform any adjustments or changes that were needed in the building process.  I love my custom home and am very grateful that I had J.W. Mumper Construction to build my dream home.  I would recommend Jim and his staff to anyone. I still use them for any improvements and just last Summer, Mumper Construction performed repair work to my garage due to fire damage from a vehicle fire.  My garage now looks new again!

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.

Our family has been working with Mumper Construction for over 30 years – two generations.  We have built new construction, remodeled and even added on – not to mention countless other small projects.  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.

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.

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.

Our residential construction project was complicated and demanding, requiring considerable new construction be integrated with 55-year-old construction, which was extensively renovated.  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.

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. Integrity, sincerity and dedication are hallmarks of his operation. Abby Freeburn, the company’s Operations Manager, is detail oriented, perfect for overseeing day-to-day scheduling and simply a pleasure to work with.

In summary, while we are thrilled with our new home, we’re going to miss working with Jim, Abby and their entire team. It was our pleasure.

Our building experience with Jim Mumper was smooth and enjoyable. It was our first building adventure. 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! Working with Jim was just the opposite. After moving to a smaller home, we decided to finish off the basement. Jim was our first choice. He gave us great advice, saved us money, and did an incredible job. I would whole heartedly recommend Jim Mumper to anyone interested in home building, adding on, or just finishing off extra space. They’re the best!

We initially met Jim Mumper and his team when we built our house in 2006.  Jim is extremely likeable and easy to work with and the process could not have gone more smoothly. Abby, at Jim’s office, is very efficient and is always available.  The attention to detail and the high quality of construction is impressive.  Several years later we finished our basement and, without hesitation, we called JW Mumper Construction to complete the project. 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.  Yes, there were problems, but Jim took care to get things right and the project back on track.  Jim has done multiple projects/remodels over the years for us and always the same quality and attention to detail.   We believe that Jim is a man of integrity and his crews act the same.  We highly recommend Jim Mumper and Mumper Construction for your next project and do not be surprised to discover you have a new friend for many years to follow!
