Transforming Basements into Dream Spaces Since 1975
Dreaming of a basement golf simulator but stuck with a ceiling that feels too low? Since 1975, our family-owned team has been Toronto’s trusted partner for custom underpinning solutions. With nearly five decades of expertise and over 10,000 successful foundation projects completed, we’ve helped homeowners turn ordinary basements into multi-purpose living spaces—including state-of-the-art golf simulators.
By carefully lowering basement floors while reinforcing the foundation, we create safe, durable spaces with the proper clearance for a full swing. From higher ceilings for golf simulators to long-term waterproofing, our solutions are built to last.
Why Basement Underpinning for Golf Simulators?
Without underpinning, most basements don’t meet the required ceiling height for a golf simulator setup. Here’s why homeowners choose us:

Adequate Swing Clearance
Gain up to 14ft of basement ceiling clearance for a comfortable golf experience!

Increased Home Value
Finished basements with specialty features boost property value.

Stronger Foundations
Underpinning not only lowers the floor but also reinforces structural stability.

Multi-Purpose Use
Create a golf simulator room and still enjoy extra basement functionality.
Our Underpinning Process
01
Site Assessment: We inspect your basement’s current height, soil conditions, and foundation integrity.
02
Planning & Permits: Detailed designs are created in line with local building codes.
03
Excavation: The basement floor is lowered carefully, section by section, while reinforcing the foundation.
04
Drainage & Waterproofing: We integrate weeping tiles and moisture protection to keep your new space dry.
05
Finishing: Once complete, your basement is ready for golf simulator installation—with all the headroom you need.
The Risks of Skipping Underpinning
Trying to install a basement golf simulator without proper ceiling clearance leads to:
- Restricted swing motion and limited playability
- Higher risk of damaging ceilings or simulator equipment
- Lower property value due to unfinished or unsafe basements
Professional basement underpinning for golf simulators ensures your investment is both functional, secure and long lasting.

Some Kind Words From Our Customers
Rob Fratric2025-05-31 Great job. Fast response to inquiries, job done fast and professionally. Put everything around the area back in place to the point where you wouldn't even know any work was done afterwards. Would 100% recommend calling them if you have a foundation repair issue. Luke Chiasson2025-04-18 Let's just say that there aren't many companies of this calibre around these days. We've been dealing with GJ MacRae for the last seven years for everything sump pump related. Seven years ago the fine folks at GJ MacRae came in and replaced our existing sump with a modern unit complete with a marine battery backup and secondary pump. We have a ton of ground water around here and when it rains our sump fires non stop. Everything has been perfect and when it came time to service our system seven years in, GJ MacRae was all over it. Exceptional service, communication price and product. It's rare to see all 3 these days. Thanks for everything Gavin. Jeff S2025-03-23 Gavin of GJ MacRae and his team did an amazing, quick and clean installation of a sump pump in our basement! I was very impressed with every aspect, from communication, to timing, to the finished product! Absolutely would recommend them! Thanks Gavin! Dave Frei2025-03-08 When you are doing a large scale project like ours (basement dig, under pin, beam replacement and waterproofing), you need an expert team like GJ MacRae. They have the experience and the know-how to give you peace of mind that the job is being done right the first time. Gavin and his team showed up on time every day with a plan and executed it with precision! These guys are the best in the business! The Impolite Canuck2024-10-27 GJ MacRae did an amazing job on my cracked foundation. Highly recommend. Guys were professional, punctual, courteous, informative and left zero mess. They even fixed some rod leaks I discovered after the second deluge last August at no extra charge. Peggy Smith2024-08-25 Very happy with a recent job completed by GJ MacRae Foundation Repair at our home. The service was excellent, the owner and working crew were very courteous and knowledgeable about their trade. They completed the work on time and on budget and they did a great job! I would highly recommend this company for any foundation/basement you may have. Brian Klodt2024-07-15 Used GJ MacRae for a foundation repair at our heritage house built circa 1894. The experience was positive from the quoting through 3 days execution of the work. Was done on time and on budget with a hard working crew who were experienced and left behind a strong and waterproof block wall. Gavin the owner was a pleasure to work with. Would use them again if ever needed. Lisa Kemp2024-07-15 G J MacRae installed a sump pump in my house to help with a water problem in my basement. The workers were professional and knowledgeable and took care with the quality of their work. They did an excellent job. I’m very happy with the result and would recommend them. Kyle Yamamura2024-06-21 Highly recommend the team at GJ MacRae. Excellent quality of work and customer service - which is hard to find these days. The waterproofing of my basement was fast, clean and effective - all at a very reasonable price. Thank you!
