John M. Jacobs Plumbing & Heating, Inc.

Letter of Introduction

Hello and Welcome to our corporate website!

John M. Jacobs Plumbing & Heating, Inc. is a fully licensed, complete mechanical contractor. Our scope of work ranges from residential plumbing to large industrial process piping. We service the tri-city area of Mid-Michigan, namely Bay City, Saginaw, and Midland.

Our scope of work includes boilers, conveyors, fire protection, gas piping, HVAC, lab plumbing, mechanical equipment, plumbing, pneumatic piping, and refrigeration. We can operate as a sub-contractor (work for another contractor) or a prime contractor (work directly for customer and supervise entire project). Jacobs Plumbing’s capacity as a prime contractor is best suited when the mechanical contract is the largest portion of a project. In addition to working under a contract, Jacobs Plumbing can perform work on a "time and material basis". All our residential work is performed on a time and material basis.

Incorporated in 1973, Jacobs Plumbing started when John became a licensed master plumber in the State of Michigan. Starting as a small residential plumber, John and Karen developed the company to accommodate larger projects. Eventually, the company could accommodate large scale commercial and industrial customers. Now, our workforce (United Association) is both large and talented enough to handle any commercial, industrial, or residential job.

A key instrument of a successful job completion is strong field supervision. Outside of John and Karen, Jacobs Plumbing has highly qualified personnel to effectively lead our projects. Our key field supervisors all have extensive experience in both their workmanship and their supervisory positions. Our key office personnel have advanced degrees of higher education or vocational training, and significant field experience.

Construction can be dangerous if necessary safety precautions and job training do not take place. Jacobs Plumbing ensures a safe working environment for all its employees and contractors through occasional safety talks and continual job training. Employees are required to have certification for operation of heavy equipment, or if working in potentially dangerous situations. Key supervision employees are trained in first aid for on-site medical attention. Our full-time safety director maintains Jacobs Plumbing's efforts to sustain a safe working environment. All employees and owners are annually required to take a drug test.

In addition to key supervision, Jacobs Plumbing is outfitted with the necessary tools and equipment to handle any project. Our equipment includes welders, threading machines, boom trucks, fleet vehicles, and several other large scale construction tools.

Within our office headquarters, we have several high performance computers which are utilized for job tracking, quoting, and bookkeeping. All computers are kept up to date with the best performing software for our needs. Design work is conducted through Computer Aided Design software allowing for electronic transfer of any design project.

Jacobs Plumbing is proud to say it is a State of Michigan Women Business Enterprise. Karen Jacobs is the president of the company. As a WBE, Jacobs Plumbing takes pride in employing diverse and highly skilled employees.

Thank you again for your interest in our Company. If you have any questions, please email us or contact us by phone: (989) 686-3782.
