What Our Customers Are Saying

  • Dan Novacek

    Do great work fast and efficient. They did a great job coordinating with our roofer to get the project done.

  • Shari Gustafson

    The polar vortex and -40 degrees (what???) did a number on our 1962 boiler and pipes. I called around town to a number of places and Todd picked up the job, came over to the house earlier than expected and repaired a burst pipe giving us heat again in less than two hours. He was knowledgeable and made a lot of sense in helping us decide our next step. I'm definitely calling them back.

  • Nancy Turrubiates

    I have received excellent service! They always answer the phone or return calls promptly. The technicians are knowledgeable about the work and answer questions. They leave behind no mess and prices are reasonable !

  • Steven Sperling

    At 4:57 pm on 1/30/2019 we noticed it getting cold in the house and our furnace not running so we immediately dialed Robert Gibb & Sons. They answered promptly (as always) and since we are regular customers in their system a service call was easily opened. Our regular tech Vincent noticed the call come in and knowing the on-call after hours tech was very busy (due to many days of subzero temps) he picked up the call (extra mile award here!) and was at our house by 5:30 pm. He had the furnace running within 15 minutes. We are always pleased with Robert Gibb & Son's prompt service, product knowledge, and work site cleanliness.

  • Preston Sternson

    When we moved into our first house, we knew the 32-year-old water heater needed to be replaced. Kipp and the team at Robert Gibb & Sons helped us through the process, helping us compare water heater options and find the best solution. They also came to the rescue over the winter when our furnace started making loud noises. After sending a text to Kipp about the issue, the service team showed up in less than an hour. I know we can count on Robert Gibb & Sons no matter what!
