Every strong home begins with what you cannot see. Beneath every wall and floor lies the foundation that keeps your property safe and stable. In a city like Toronto, where older houses meet new construction, the ground can shift, water can build up, and foundations can weaken over time. At G1000 Home Substructure, we specialize in protecting homes from those challenges with professional waterproofing, underpinning, and concrete services.
We have helped hundreds of homeowners across Toronto strengthen their homes from the ground up. Whether it is a small crack repair or a full basement lowering project, our focus is on doing the job once and doing it right.
Basement Waterproofing for Toronto Homes
Toronto’s climate can be tough on foundations. With spring rains, humid summers, and freezing winters, water finds its way into basements more often than people expect. A small leak can quickly lead to mold, damaged drywall, and structural issues.
That is where our team comes in. We provide long-lasting waterproofing solutions that are custom-fitted to your home and soil conditions. No two basements are the same, so we always start with a careful inspection before recommending the best system for you.
Our waterproofing services include:
- Interior and exterior waterproofing
- Foundation crack injection and repair
- Sump pump and battery backup systems
- Weeping tile and French drain installation
- Moisture barrier and vapor control systems
Each solution we install is designed to prevent future water intrusion, not just stop the current leak. When we waterproof a basement, we protect your investment, your comfort, and your air quality.
Underpinning and Basement Lowering in Toronto
If you live in Toronto, you know space is valuable. Many homeowners want to turn their basement into a livable space or rental unit, but low ceilings or weak foundations make that difficult. Underpinning is the answer.
Our underpinning service allows you to lower your basement floor safely while reinforcing the foundation. This adds height, strength, and long-term stability to your structure.
You may need underpinning if you are:
- Planning to convert your basement into a legal apartment or family suite
- Seeing cracks in walls or floors that keep expanding
- Dealing with uneven floors or settling
- Looking to increase property value and usable space
We handle everything from design and permits to excavation and concrete pours. Our team works under strict safety standards and always keeps your home structurally secure throughout the process.
When done correctly, underpinning can turn an outdated basement into one of the most valuable parts of your property.
QUALITY CONCRETE WORK THAT LASTS
Concrete is one of the most important materials in construction. It supports your home, shapes your landscape, and carries the weight of daily life. At G1000 Home, we believe concrete work should not just look good on day one, but hold strong for decades.
Our skilled concrete team handles everything from new installations to replacements and repairs. Whether you need a new driveway or a complete basement slab, we make sure every surface is level, durable, and built with precision.
Our concrete services include:
- Driveways, patios, and walkways
- Garage floors and basement slabs
- Retaining walls and steps
- Concrete pads for sheds, air conditioners, or hot tubs
- Concrete removal and repouring
All our concrete projects are done with high-strength mixes designed to withstand Toronto’s temperature changes. You can count on smooth finishes, clean edges, and long-lasting durability.
COMPLETE FOUNDATION AND STRUCTURAL SERVICES
Your foundation does more than support walls; it protects your entire home. Along with waterproofing and underpinning, we offer additional structural and drainage services to ensure every part of your home’s base stays secure.
Additional services include:
- Foundation crack repair and stabilization
- Structural beam and support installation
- Basement walkouts and egress windows
- Drainage correction and grading
- Bench footing and partial lowering
We combine engineering precision with field experience to deliver work that is safe, code-compliant, and built to last.

How Much Do Waterproofing and Underpinning Cost in Toronto
The cost of home foundation work depends on several factors, including the size of your home, accessibility, and the type of repair or installation required. On average:
- Waterproofing projects start in the low thousands and depend on the total length of wall treated.
- Underpinning is priced per linear foot and includes excavation, reinforcement, and new concrete foundations.
- Concrete work varies depending on size, depth, and finish type.
We always provide a written estimate after inspecting your home so that you know exactly what you are paying for. Transparency is part of our process, from start to finish.
Frequently Asked Questions
Our exterior waterproofing solutions address foundation cracks from soil movement, basement flooding due to poor drainage, mold and mildew from moisture buildup, sagging floors indicating foundation stress, and drainage issues causing water pressure on foundation walls.
How can I tell if my basement needs waterproofing?
Look for damp walls, musty smells, or white residue on the surface. These are all signs that moisture is entering through your foundation.
Is underpinning safe for older homes in Toronto?
Yes. When done correctly by professionals, underpinning strengthens the original foundation and makes the home even more secure.
How long does a typical basement lowering project take?
Most underpinning projects take between four and eight weeks depending on access and size. We manage the permits, inspections, and construction timeline for you.
Can waterproofing be done from the inside only?
Yes, interior systems can be installed when exterior access is limited. However, exterior waterproofing remains the most durable and long-term solution.
