What Our Clients Say

  • “Eric and his team at Mundfrom Builders were fantastic to work with. All of our (many) questions were answered promptly, professionally and honestly. We always knew the timeline of the build and he communicated any changes as soon as he knew. During the design process, his experience and expertise helped us customize our plan to fit our family's needs, budget and make the best use of the space we had. They were extremely patient as our start date was delayed for reasons on our end. Once construction started, there was consistent progress made and rarely a day without someone on site. Eric helped troubleshoot and adapt to the unique challenges our build site presented. He was always aware of the ever-changing supply delivery timelines and ensured we made our selections early enough to keep our build on track. Eric and his team of vendors/subcontractors were easy to work with and accommodating as our young family continued to run our farm on site during the construction process. In the end, Eric and his team took our ideas and built our dream home, a true legacy, we look forward to passing onto future generations. We highly recommend Eric and Mundfrom Builders for any home building needs.”

  • “The Mundfrom family is a collective group of creativeness! I have enjoyed getting to know them through their family business and see the work Eric can manifest as well as Tiffany’s eye for detail and beauty. I recommend Mundfrom Builders for any future home needs.”
