What is Underpinning?

Underpinning is the process of strengthening and deepening an existing foundation that has become unstable, cracked, or insufficient for the structure above it. It's also commonly used to lower a basement floor to create more headroom and living space. At A & A Setting Stone, we specialize in mass concrete underpinning — the most trusted and proven method used across Toronto. Whether your foundation has shifted due to soil movement, age, or a neighboring construction project, our licensed engineers and contractors will assess the situation and restore your foundation's integrity safely and efficiently.

Our 3 Step Process

1. Structural Assessment

We inspect your existing foundation, identify the cause of instability, and develop a custom underpinning plan that meets Toronto building codes and engineering standards.

2. Underpinning Excavation & Pouring

Working in carefully planned sections, we excavate beneath the existing foundation and pour new concrete to extend and strengthen it — without compromising the structure above.

3. Waterproofing & Final Inspection

Once the new foundation is cured, we apply waterproofing protection and conduct a full inspection to ensure your structure is safe, stable, and built to last for decades.

TESTIMONIALS

What others are saying

"I thought I knew what hardworking was"

"I tought I knew what "hard working" means but Bledi, Eric and their team raised the bar so high that I have to reconsider. I had a chance to use their expertise for my house in midtown Toronto and work with no one else as long as they are in business of helping the client with every aspect of the construction project."

- Babak Sharaji

"Amazed by the driveway"

"Totally amazed by the driveway that they did for me! The crew was professional, showed up on time every day, and kept the work area clean throughout the whole project. The finished result exceeded my expectations — the stonework looks absolutely incredible and has completely transformed the front of my home. I've already had neighbors ask me who did the work. Will definitely be calling A & A Setting Stone again for my backyard patio!"

- Ermal Kamperi

"Professional, Clean, & On-Time"

Frequently Asked Questions

Common questions homeowners and businesses ask us before starting an underpinning project.

Question 1: How do I know if my home needs underpinning?

Common signs include cracks in your foundation walls, uneven or sloping floors, sticking doors and windows, and visible gaps between walls and ceilings. If you notice any of these warning signs don't wait — call us for a free assessment before the problem gets worse and more expensive to fix.

Question 2: Can underpinning be used to lower my basement ceiling height?

Yes — this is actually one of the most popular reasons homeowners in Toronto call us. Underpinning allows us to dig down and lower your basement floor, giving you significantly more headroom and turning an unfinished basement into a fully functional living space.

Question 3: Is underpinning safe for my home?

Absolutely. When done by licensed and experienced professionals like our team at A & A Setting Stone, underpinning is a very safe and proven process. We work in carefully planned sections to ensure your home's structure is fully supported at every stage of the project.

Question 4: Do I need a permit for underpinning in Toronto?

Yes, underpinning requires a building permit and structural engineering drawings in Toronto. Our team will guide you through the entire permit process and ensure all work meets Ontario Building Code requirements before we begin.

Question 5: How long does an underpinning project take?

Most residential underpinning projects take between 2 to 6 weeks depending on the size of your basement and the depth of excavation required. We'll give you a clear and detailed timeline during your free consultation so there are no surprises.
