Verified record
Kendall Boiler & Tank Co. is a Chelmsford, Massachusetts, boiler repair business that says it has been family owned and operated for four generations since 1860, offering 24/7 emergency service and naming a service area running from Boston to Providence, RI. Its written record is dated: in a 2018 review a customer called it certified welders for commercial boilers, and in a 2021 review a customer said they showed up on time and did a great job. A patch.com article reported that a school district was billed nearly $37,000 for boiler repair work reportedly performed by the company in November 2021, but an auditor found the boiler inoperable by December 2023.
