Mechanical Pipefitting for Steam, Hydronic, Gas and Refrigeration Systems
New piping, replacements and system additions on commercial and industrial mechanical systems, self-performed by an owner-operated contractor.
We install, repair and retrofit the distribution piping for boilers, chillers and HVAC equipment, and we take on standalone piping jobs large and small.
We understand every common joining method and the materials used across steam, condensate, hot and chilled water, gas and refrigeration systems.

FAQ
Questions about pipefitting
What pipe materials do you work with?
Black iron in schedule 40 and 80, copper types K, L, M and ACR, PEX up to 2 inch, and PVC, ABS and CPVC. We join pipe by threading, welding, brazing, flanging and soldering.
Do you take piping jobs that are separate from a boiler or chiller project?
Yes. We take standalone piping work of any size, from a single repair to a full replacement.
Can you replace piping in an occupied building?
Yes. For the Twin Falls School District we replaced worn piping and expansion tanks across multiple buildings, with major shutdowns scheduled for summer and off-school windows.
Who does the piping work?
Matt Grant, the owner, performs most of the work himself. Grant Mechanical self-performs its mechanical scope, so the piping stays with the same contractor as the equipment.
