I found the leaking hybrid water heater tank to be cracked. I replaced it under warranty. Thank you!
Jack was on time and professional upon his arrival to my home. He quickly diagnosed the problem with my hot water heater and had it fixed on the same day. Granite State Mechanical offers unsurpassed customer service and expertise in the area of heating plumbing and cooling. I tell all my neighbors how great they have treated me, and I am so glad I chose GSM to install and service my home HWH and Mini split.
We thank you for sharing your positive experience. It made our day.
