About A&B Mechanical Contractors
Initially known as A&B Builders, our company was formed in 2004 by Brian Klein of Sparta, Michigan. Mr. Klein had 20 years experience working in the construction trades and a desire to manage his own business. Under his direction, the company quickly grew and added professional trade licenses and services. Today our family owned company operates as A&B Mechanical Contractors, Inc. and is a single resource for commercial, residential and industrial construction and trade services.
We are unique because we are licensed in Plumbing, Mechanical, Electrical, and Building services; plus, we offer sheet metal fabrication. Our diversification is designed to promote both convenience and cost savings to our clients. Our mission is to provide our customers with the best value in the local mechanical, electrical and plumbing construction industry. We accomplish our goals through competent employees strong on work ethic and motivated by personal responsibility and trust.
