The MacRae Clan in the Early Years

During the early years when residential basements were mainly used for coal and 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, entirely 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.
1970 – 1975

1975 – 1985

Specialization

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.
1975 – 1985

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.
1985 – 1995

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.
1995 – 2000

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.
2000 – 2005

2005 – Present

Five Decades Later!

Nearly 50 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.

2005 – Present

1985: Brand New Truck

Back then, pickup trucks were much rarer than today, so our first new pickup truck was an exciting accomplishment for our family!

1993: Noreen and John

Noreen and John in the mid 1990’s in their new home in Orangeville! Every week felt like an adventure in these days!

1981: Early Connections

A reference from Bob Patterson of CFRB (now Newstalk 1010 / Bell Media). It was an excellent opportunity for John in the early years.

1988: The Kids Keep Growing

The kids grew up in these old pickup trucks and were always excited to play in them with Dad after a long week on the job site.

1975: Out Of Town Projects

Ottawa’s Carleton Place contracted John MacRae and his brother Don MacRae for many fulfilling years of reliable repairs and service.

1976: Carleton Town Hall

Another trusted repair by John and Don MacRae on the Carleton Place Town Hall. Referrals have always been an integral part of our success.

Some Kind Words From Our Customers

We had a leak from two sources in our furnace room, that occurred after a moderate to heavy rainfall. We hired GJ Macrae to excavate by the outside wall, repair the cracks and protect the wall with a membrane and mesh. Part of the trench had to be dug by hand, due to a gas line, and part could be done by machine. The GJ Macrae team were all very skilled and professional, and completed the job in three days. Now the trench has been refilled with the earth and gravel and it will take some time for the ground to settle. We have had a few heavy rains since the job was completed, and our basement is now completely dry! We highly recommend GJ Macrae!

From our initial discussion with Dean through to the completion of the project I was most impressed with knowledge and professionalism. We had foundation damage from a tree root and they took the time to explain what was required and the steps involved in rectifying the situation. I highly recommend GJ MacRae for any foundation work you may need.

Honest, courteous, thorough, professional, reliable, on-time, clean and trustworthy. Solved our home’s basement water concerns caused from living on the flood plain (water table). Would definitely recommend GJMacRae Ltd as the company to fix your wet basement. Dean and his crew’s attention to detail solved the various challenges of our 91 year old home.

Dean, came out right away after we noticed water in our basement and provided an estimate. Communication with him was easy and he answered all my questions. Work was done within the week. I had a great experience and will recommend to others.

Gavin and his team did a great job. Right from quoting the job I had confidence they can do the job well and had the experience. Great videos on their website really help you understand what’s involved in foundation repair.

Job was done in 2 days which I was amazed it could be done that quickly! That’s a lot of pails of concrete and rock that had to be shuttled in and out of the house! The guys were all very friendly and let me know everything that was being done and answered all my questions! The bowed wall looks solidly supported now with carbon fibre strapping and the water found beneath the floor is now being safely routed through newly installed Plastic Weeper to our sump. We now have peace of mind that we can finish the basement with no leaks or crumbling walls! Thankyou Gavin, Maggi, Ricardo and Jay!

We would like to express our gratitude to G.J. McRae for the exceptional job they did in restoring our peace of mind. Every time it rained or snowed, our basement would leak, causing us great distress. However, the crew from G.J. McRae arrived promptly, worked diligently, and efficiently resolved the issue. They even left our backyard in excellent condition, cleaning up after themselves. We cannot thank you enough for the outstanding service and for making us feel confident that the problem is now completely resolved. We are so happy to be able to not worry about this any longer.

Workers were on time and professional. Quality and value for money. My only issue was the concrete poured was a little uneven causing a small lip near the drain. We managed to smooth it out. Would highly recommend GJ MacRae Foundation Repair.
