What Our Customers Are Saying

  • Josh Anderson

    I recently worked with Job Ebsen on having a garage heater installed. He came over and let me know all my options, along with info on heater size suitable for my garage. He had an estimate to me the same day and was able to schedule the work to be done the following week. They did a great job with the installation, even putting a covering over the gas line on the outside of the house to make it look better. I would definitely call Jon again for future work!

  • Linda Lakeman

    We needed our 40 year old tiled shower replaced. Called Robert Gibb & Sons and received prompt, courteous, and expert service. Mike Wollenberg came over to see what we wanted done, gave us an estimate and followed up with the progress. We had a great plumber and carpenter that did professional work and were always making sure the project was turning out like we had planned. We now have a new beautiful surround fiberglass shower. Robert Gibb & Sons care about their customers.

  • Carly Hearn

    I received excellent service from Robert Gibb and sons. Bob Wagner came over and fixed my plumbing issues quickly. He was so kind and patient with me and explained the problems and solutions to me. I would personally recommend Bob and Gibb and Sons for quick and reliable service. I haven’t had any problems since then. Thanks guys!

  • Brian Driscoll
