A strong foundation is essential to the safety, stability, and long-term value of your home. When cracks, settlement, shifting walls, or other foundation issues appear, identifying the cause early can help prevent more extensive damage and costly repairs.
Leaquida provides foundation repair near me services for homeowners in Toronto and across the Greater Toronto Area (GTA). Our team assesses the condition of your foundation, identifies the factors contributing to the problem, and recommends a repair approach suited to your property rather than relying on a one-size-fits-all solution.
Whether you are dealing with visible cracking, foundation movement, or concerns about the stability of your home, our experienced team can inspect the problem and explain the available options before any repair work begins.
Toronto homes sit on a wide range of foundations — poured concrete, concrete block, stone and mixed-material walls in older neighbourhoods — and each behaves differently when soil moves or water builds up. Our foundation contractors work with all of them and explain, in plain language, what is happening and what it will take to fix it.
Signs Your Toronto Home May Have Foundation Problems
Foundation problems can develop gradually, and the first signs are not always easy to recognize. A new crack, uneven floor, or sticking door may appear to be a minor issue, but these changes can sometimes indicate movement, settlement, moisture, or other conditions affecting the foundation.
Look for signs such as:
New or widening cracks in foundation walls, floors, or masonry
Bowing, leaning, or shifting basement walls
Uneven or sloping floors
Doors and windows that stick or no longer close properly
Water entering through foundation walls or floor joints
Gaps appearing around windows, doors, floors, or exterior walls
Visible settlement or changes in the ground around the property
Not every visible defect means that major structural work is required. Some issues can result from normal concrete shrinkage, minor settlement, aging materials, or cosmetic deterioration. The significance of a particular symptom depends on its location, progression, and relationship to other changes in the property.
If you have noticed one or more of these signs, a foundation specialist can assess the condition of your property and help determine whether the issue requires foundation repair or another type of corrective work.
Types of Foundation Cracks and What They Mean
Not every crack is a structural problem, but every crack is worth understanding. The direction, width and behaviour of a crack tell a foundation contractor a lot about its cause. Use this table as a general guide — only an on-site inspection can confirm what your crack means.
Our Foundation Repair Services in Toronto, Ontario
Every foundation problem requires a solution suited to the condition of the property. Leaquida combines structural repair, stabilization, and water management to address foundation issues throughout Toronto and the GTA. Our foundation repair contractors assess the damage and select the appropriate method based on the foundation type, soil conditions, moisture, and extent of movement.
Foundation Crack Repair
Foundation crack repair can include epoxy or polyurethane injection, depending on the condition of the crack and the presence of moisture. Epoxy is commonly used for suitable dry cracks, while expanding polyurethane is effective for cracks where water is present.
For wider or more significant cracks, repairs may involve interior routing and patching combined with exterior excavation, hydraulic cement repair, and membrane installation. The appropriate method depends on the crack type, location, severity, and condition of the surrounding foundation. A foundation repair contractor can determine the most suitable repair method and address the crack according to the condition of the foundation.
Foundation Structural Repair
Foundation structural repair addresses settlement, shifting, and other conditions that affect the stability of a home. Solutions can include helical piers for lighter structures, as well as push piers and slab piers for heavier homes requiring support at deeper, load-bearing soil layers.
Underpinning and bench footings can strengthen and deepen existing foundation support where additional stabilization is required. The appropriate method depends on the structure, soil conditions, and extent of movement.
Foundation Wall Stabilization
Foundation wall stabilization is designed for basement walls that are bowing, leaning, or shifting due to structural movement or pressure from surrounding soil. Depending on the condition of the wall, stabilization can include carbon-fiber straps, steel braces, wall anchors, or I-beams.
The selected reinforcement method is based on the construction of the wall, severity of movement, and structural requirements of the property. These solutions provide additional support and help prevent further wall movement.
Drainage, Soil & Waterproofing Solutions
Drainage, soil, and waterproofing services address conditions that can contribute to foundation damage and water intrusion. Solutions include interior and exterior drainage systems, weeping tile, French drains, sump pump installation, and exterior foundation waterproofing.
Grading and gutter optimization can also help direct water away from the property and reduce moisture around the foundation. Where soil and water conditions contribute to structural problems, these services can be incorporated into a broader foundation repair service for properties throughout Toronto and the GTA.
Drainage and moisture-control solutions can also include crawlspace encapsulation, where appropriate, to help protect crawlspace areas from excess moisture and improve the overall moisture management of the property.
Underpinning and Bench Footings
When a foundation needs to go deeper or carry more load — for example before lowering a basement — underpinning and bench footings extend support to stronger soil. These projects are planned with structural requirements and permits in mind. More details are on our foundation structural repair page.
Basement Floor and Slab Repair
Cracked, heaved or sunken basement floors are repaired or replaced as part of the foundation project, often together with drainage work under the slab. See our concrete floor installation service.
What Causes Foundation Damage in Toronto and the GTA
Clay Soil That Swells and Shrinks
Much of the GTA sits on clay-rich soil that expands when wet and contracts when it dries. That constant movement pushes on foundation walls and can cause settlement and cracking over time.
Freeze-Thaw Cycles
Water in the soil freezes, expands and thaws many times each winter. The resulting frost heave and soil movement add stress to footings and walls, and water that enters existing cracks widens them as it freezes.
Poor Drainage and Grading
Downspouts that discharge next to the house, negative grading and blocked weeping tile let water collect against the foundation. The result is hydrostatic pressure, leaks and soil that loses its bearing capacity.
Tree Roots
Large trees close to the house can draw moisture from the soil under the foundation and disturb it as roots grow, contributing to uneven settlement.
Plumbing Leaks and Water Pressure
A leaking pipe or failed waterproofing keeps the soil saturated. Water pressure on the walls leads to seepage, efflorescence and, eventually, cracking and bowing.

Our Foundation Repair Process in Toronto
Every foundation project starts with understanding what is happening beneath and around the structure. The foundation repair experts at Leaquida follow a structured process to identify the problem and determine the most appropriate repair approach.
Thorough Inspection. The team examines interior and exterior areas, including visible cracks, foundation walls, drainage, soil conditions, and signs of moisture or movement. Where necessary, the inspection includes crack measurements, moisture checks, photographs, and documentation of affected areas.
Detailed Assessment. The information collected during the inspection is used to determine the likely cause and extent of the problem. This helps establish whether the property requires structural stabilization, wall reinforcement, drainage work, waterproofing, or another solution.
Repair Implementation. Once the appropriate approach is determined, the work is completed by in-house crews using suitable materials and established repair methods. Depending on the project, this may include pier installation, underpinning, wall stabilization, drainage improvements, waterproofing, or concrete floor installation where required as part of the property’s foundation-related work.
Final Review. After the work is completed, the repaired areas are reviewed to ensure the planned work has been properly carried out and the property is left in suitable condition.
Bonds the crack and restores the wall’s continuity
Polyurethane injection
Cracks where water is present
Expands to seal the crack against leaks
Exterior crack repair with membrane
Wider cracks or cracks that keep leaking
Excavation, hydraulic cement repair and a new membrane on the outside
Carbon-fibre straps
Walls with early bowing or horizontal cracks
High-strength straps bonded to the wall add tensile strength
Steel braces, wall anchors or I-beams
Walls with more significant bowing or leaning
Brace the wall against further inward movement
Helical, push or slab piers
Settled or sinking sections of foundation
Transfer the load to deeper, load-bearing soil
Underpinning and bench footings
Deepening or strengthening the existing foundation
Extend footings to provide additional support
All of these methods are already part of Leaquida’s foundation services; the right one depends on the crack type, wall construction, soil conditions and how much movement has occurred.
Permits and Building Code for Foundation Repair in Toronto
Some foundation work is a simple repair; some changes the structure of your home. According to the City of Toronto’s guide on when a building permit is required, structural or material alterations need a building permit, and so does installing a backwater valve.
Building work in Ontario must also meet the Ontario Building Code; the 2024 edition came into effect on January 1, 2025. During the assessment we explain whether your project needs a permit or engineering input, and we plan the schedule so inspections can take place before work is covered.
Our Basement Waterproofing Services
EXTERIOR
Exterior waterproofing is one of most efficient and reliable ways to perform waterproofing of your property.
The cost of foundation repair Toronto homeowners may need depends on the type of damage, accessibility, foundation condition, and repair method. The prices below are approximate ranges based on the services offered by Leaquida:
Service
Approximate Cost
Foundation Crack Repair
from $500 per crack
Structural Piering & Underpinning
from $1,500 per pier
Wall Stabilization
from $800 per section
Drainage & Water Management
from $2,000
A complete project can cost more depending on its scope. For example, structural piering and underpinning may range from $10,000 to $35,000+, while wall stabilization can range from $5,000 to $15,000.
The final price is determined after assessing the property, the extent of the problem, and the work required. A foundation repair contractor can provide a more accurate estimate following an inspection. Contact our team to schedule an inspection and receive an accurate estimate for your project.
Foundation problems rarely stay the same size. Waiting usually means:
cracks that widen with every freeze-thaw cycle;
water seeping into the basement, followed by dampness, odours and mould;
walls that continue to bow or lean under soil pressure;
doors, windows and floors that move further out of level;
a larger, more expensive repair than the one needed today;
problems that surface during a home inspection when you sell.
An early inspection costs nothing and lets you decide with full information.

Foundation Repair vs Foundation Structural Repair
Foundation repair covers the full range of work on your foundation — from sealing a single crack to stabilizing a wall or improving drainage. Structural repair is the part of that work that restores how the foundation carries the house: piering, underpinning, bench footings and major wall reinforcement. If your inspection shows settlement or significant movement, learn more on our foundation structural repair page.
How can I tell if a foundation crack is serious or just cosmetic?
Not all cracks require immediate attention, but some are warning signs of structural issues. Hairline vertical cracks under 1/8 inch are often caused by concrete shrinkage during curing and may not pose a threat. However, you should be concerned if the cracks are:
Wider than 1/4 inch and growing
Stair-step cracks in brick or block walls
Horizontal or diagonal cracks (especially in basement walls)
Accompanied by water seepage or bowing
In these cases, you may need foundation crack repair or full foundation structural repair. A professional inspection is the best way to evaluate the severity and prevent long-term damage.
What is the difference between foundation repair and basement waterproofing?
They serve different purposes but are often related:
Foundation repair fixes structural issues like cracks, settlement, bowing walls, and footing failure. It focuses on restoring the integrity of the home’s support system.
Basement waterproofing prevents water from entering the foundation and interior basement walls, usually through membrane installation, sump pumps, or drainage systems.
In many cases, both services are needed. For example, foundation leak repair may involve stabilising cracks and then waterproofing the area to prevent future issues.
How long does foundation repair take, and will I need to leave my home?
Most minor foundation wall crack repair jobs take 1 to 2 days. Larger repairs, such as installing piers or reinforcing basement walls, can take up to 10–14 days, depending on weather, soil condition, and project scope.
You can usually remain in your home during the work unless there are severe safety concerns, such as wall collapse or floor instability. In rare cases, we may recommend temporary relocation during emergency foundation repair.
Is a warranty provided for foundation repair work?
Yes, at Leaquida Waterproofing, we stand behind our work. Most of our structural foundation repair services, such as underpinning, crack injections, and wall stabilization, come with long-term warranties — some transferable to future homeowners.
This warranty coverage gives you peace of mind, knowing that your foundation repair company is committed to lasting solutions, not quick fixes.
Can you fix a foundation leak from the inside?
Yes. For smaller cracks, we use high-pressure polyurethane injections. However, for serious foundation leaks, an exterior approach is often better to block water pressure before it reaches the concrete.
What is underpinning and when is it necessary?
Underpinning involves strengthening and deepening your existing foundation. It is necessary if your home is sinking or if you plan to increase basement height. We are experienced concrete foundation contractors near me specializing in these upgrades.
How much does foundation repair cost in Toronto?
Foundation crack repair starts from $500 per crack, structural piering and underpinning from $1,500 per pier, wall stabilization from $800 per section and drainage work from $2,000. Complete projects can cost more depending on scope — we give you an exact estimate after a free inspection.
Do I need a permit for foundation repair in Toronto?
Structural or material alterations require a building permit from the City of Toronto, while smaller repairs such as sealing a crack usually do not. We explain the permit requirements for your project during the assessment.
Are horizontal cracks in a basement wall serious?
Horizontal cracks often indicate soil and water pressure pushing on the wall and may come with inward bowing. They should be inspected promptly, because wall stabilization is simpler and less expensive before the wall moves further.
Do you use subcontractors for foundation repair?
No. Foundation projects are handled directly by Leaquida’s own experienced in-house crews.
Reviews about us
Quick, professional and at very reasonable cost. No hidden costs. The installation was complicated as the municipal sewage backed up when the pipe was cut, but the team did not complain despite working in harsh conditions.
Lev, WhitbyVacancy
Leaquida Waterproofing was prompt, courteous and thorough. We would recommend to anyone. We had a backwater valve installed. I called Sunday, got a quote Monday, has the work done the following Monday (including issuing of building permit).
Trisha GrantVacancy
They have installed sump pump system in our house. They were very much on time and during the installation they have worked very clean.
You may rely on their advises.
Highly recommended.
