About us
Our team brings widespread management experience, quality
craftsmanship, sound financial support and innovative solutions to
each and every building project

Our History
Founded in 1988, the Grassmere name is derived from Lake Grassmere, which was part of the Wisconsin Glacier approximately 13,000 years ago. Also known as Lake Lundy, Lake Grassmere once covered southern Ontario, half of the state of Michigan and even reached as far east as Syracuse, New York. The name was chosen for its uniqueness and because the company was determined it had something special to offer.
To earn client loyalty, Grassmere prioritizes expert advice, management knowledge, competitive pricing, quality service and on-the-job safety programs. These strengths have built Grassmere’s reputation as a consistently solid, dependable operation that offers superior service to all areas of every building project.

Mike Booth has been a part of the company since 1989 and today is sole owner and President of Grassmere Construction Ltd.
Grassmere continues to follow this vision by providing exceptional service to our clients and maintaining a stellar reputation in the Design-Build Construction Management field for over 30 years.
“At Grassmere each client and project is unique. Catering to our customers is key and providing the best service possible we create a successful partnership with them throughout the construction process. Our goal is to establish lasting relationships with our customers by exceeding their expectations and gaining their trust through exceptional performance by every member of Grassmere’s team. We take pride in our accomplishments and strive to build on them every day!”
