Trusted Company.
Exceptional Team.

At Gilman, we're proud of our long-standing reputation in the community as a trusted HVAC company, but we wouldn't be where we are today without our talented team of technicians, plumbers, and customer service reps. The faces behind the Gilman brand are what make us the company we are today!

Customer Feedback

    They not only replaced my faucet, but did an annual plumbing inspection which I’ve never had and was hugely helpful. I would highly recommend this company for the way they treat their customers and the good service.

  • Janelle H, Sept 23, 2023

    Wonderful first experience with Gilman Plumbing, It's so hard to find good people out here in the NNK. I called them with a non-emergency today and within 30 min they were at my house and repaired everything within 1 hour 40 min from first call to a finished product. Thank you so much Gilman, we are customers for a long time!

    I have used Gilman's for years and have never been disappointed. The men who come out are always polite, respectful, and careful to explain what is going on and what my options are. I cannot say enough how much I recommend them for whatever service you may need.

    I can not say enough good things about the team at Gilman in Kilmarnock. Whenever I have had an issue I get a very timely appointment due to great administrative management. Everyone from front desk to HVAC and plumbing are great to work with. They will not quit until the job is done. Kudos especially to "Noah" for two days of dead ends with a drain clog. He kept a pleasant attitude no matter how messy the job became! I highly recommend Gilman. Thanks for a great job every time.

    We had an area in the kitchen with damp drywall. Gilman sent a technician early the next morning who found the leak, verified where it was coming from, removed damaged pipe and installed new pipe. Our technician Chris was professional, knowledgeable, and completed the job timely. I would recommend Gilman to any of our neighbors.
