Just A Wee Little Bit About Us!

During the early years when residential basements were mainly used for coal, food storage (and the occasional hogmánay) we were one of the first contractors in the Toronto area to realize the incredible benefits of a fully dry, fully usable basement.

1970 – 1975

The Seed Is Planted

“As dearcáin bheaga a fhásann na crainn is airde: mighty oaks from little acorns grow”. John MacRae begins specializing in below grade concrete waterproofing projects with his father.

1975 – 1985


Noreen and John MacRae welcome three children into the world and although times were tough in the early years they always found a way to make ends meet. GJ MacRae slowly begins to gain traction.

1985 – 1995

The Next Generation

The kids become involved on the weekends helping Dad clean up job sites while they study and nibble on timbits. Gavin shows a keen interest in masonry and the seed continues to grow.

1995 – 2000

A New Century

GJ MacRae becomes a full service foundation repair company specializing in basement waterproofing, structural foundation repair and underpinning. The kids work with the crews during the summer and the collective interest continues to expand.

2000 – 2005

The Transition

More specialized projects become attractive as our expertise and experience grows. Platon replaces tintest, weeping tile detail changes within the OBC, John transitions to sales and Gavin starts his first full time crew.

2005 – Present

Four Decades Later

More than 45 years have passed and the mighty oak still grows! GJ MacRae continues to set the bar in all phases of below grade waterproofing, structural foundation repair, underpinning and heritage restoration.
