Signs that you Need Foundation Repairs

Over time, problems described above lead to foundation damage of various extent – hairline wall & floor cracks, sticking windows and doors, deep foundation cracks and more. Make sure to talk to foundation repair professionals if you suspect that your foundation needs repairs. Here is a couple of signs of damaged foundation that we see most often:


  • Basement Wall & Floor Cracks - look for cracks in the interior or exterior walls and even drywalls. The cracks can have different widths from hairline to 1/8 of an inch and wider. Pay attention to diagonal cracks, stair-step cracks, or horizontal cracks, as they can indicate different types of foundation movement.

  • Uneven or Sloping Floors - if you notice that your floors are uneven or sloping, it could be a sign of foundation issues. This is particularly noticeable if you place a ball on the floor, and it rolls in a certain direction.

  • Sticking Doors & Windows - If your doors or windows suddenly become difficult to open or close, or if you notice gaps around them, it may be due to a shifting foundation. As the foundation moves, it can cause the frames to become misaligned.

  • Sagging or Bowing Walls – are likely a result of foundation problems. This is a very serious issue that should be addressed promptly to prevent collapse.

  • Gaps Around Doors & Windows - check for noticeable gaps or separations between the door or window frames and the walls. These gaps can occur as the foundation settles or shifts, affecting the alignment of the openings.

  • Basement Moisture & Water Intrusion – damp basement, wet basement walls & floors, mold growth, pooling water, and other signs can indicate foundation issues, such as cracks that allow water to seep in.

  • Chimney Issues - a leaning or tilting chimney can be an indication of foundation problems. If you notice that your chimney is separating from the house, leaning to one side, or has visible cracks, it's important to talk to an expert.


The list goes on. If you observe any of these signs, it's recommended to consult with a professional foundation repair contractor or a structural engineer. They can assess the situation, determine the cause of the issues, and recommend appropriate repairs to stabilize and restore your foundation.

Why Repair Foundation Damage?

What are the Benefits of Foundation Repairs?

The question answers itself. It is important to deliver foundation repair Mississauga to prevent further damage and to protect your property. Here are some other key benefits of foundation repair:


  • Structural stability - the primary benefit of foundation repair is restoring the structural stability of your home or building. By addressing foundation issues promptly, you can prevent further damage and potential collapse. Repairing the foundation ensures that the entire structure is supported properly, reducing the risk of structural failure.

  • Improved Safety - a stable foundation promotes the safety of occupants and visitors. It minimizes the risk of accidents caused by sagging floors, collapsing walls, or other structural hazards. Foundation repair helps create a secure living or working environment by addressing potential safety risks.

  • Protection of Property Value - your home or building is a significant investment, and maintaining its value is essential. Foundation problems can significantly decrease property value, making it difficult to sell in the future. By investing in foundation repairs, you preserve and potentially increase the value of your property, making it more attractive to potential buyers.

  • Prevention of Further Damage - foundation issues tend to worsen over time if left unaddressed. Small cracks or shifts can lead to more significant problems, such as extensive structural damage, plumbing issues, or roof problems. Repairing the foundation early prevents these issues from escalating, saving you from costly repairs down the line.

  • Improved Energy Efficiency - foundation problems can cause your home to become unlevel, leading to gaps and misalignments in doors and windows. These gaps allow air leakage, making it difficult to maintain consistent indoor temperatures. By repairing the foundation, you can restore proper alignment, enhance insulation, and improve energy efficiency.

  • Peace of Mind - dealing with foundation issues can be stressful for homeowners and building owners. The uncertainty about the safety and stability of your property can take a toll on your peace of mind. Foundation repair provides reassurance and peace of mind, knowing that your property is secure and protected.

Foundation Crack Repair Cost
Mississauga - $1,500-$3,200

Pressure Grouting

Pressure grouting is a technique used to strengthen and stabilize the soil or fill voids beneath a foundation. It involves injecting a cementitious grout mixture under pressure into the ground through boreholes or pipes. The grout fills gaps, compacts loose soil, and improves the load-bearing capacity of the soil, providing additional support to the foundation and preventing further settlement or movement.

Sinking Outdoor Concrete Repair

Sinking concrete is commonly caused by soil settlement, inadequate soil compaction, or poor drainage, which can impact the stability of the foundation. Addressing the sinking concrete typically involves addressing the underlying foundation problems to ensure long-term stability and prevent further damage.

Basement Underpinning (Floor Lowering)

Basement underpinning is a structural foundation repair technique that involves strengthening and stabilizing an existing foundation by extending its depth or breadth. It typically involves excavating beneath the existing foundation and adding new concrete or steel supports to reinforce the structure. Underpinning is commonly used to increase the load-bearing capacity of the foundation, address foundation settlement, or allow for additional basement space. In some cases basement underpinning is used for basement floor lowering Mississauga purposes.

Basement Underpinning Cost $15,000-$50,000+

Mud Jacking

A sump pump is a mechanical device that is used to remove excess water from the basement or crawl space of a building. It is typically installed in a sump pit, which is a hole dug into the basement floor or crawl space. The sump pump is designed to automatically activate when the water level in the sump pit reaches a certain point, and then pumps the water out of the pit and away from the building. A sump pump is a common element of internal basement waterproofing systems.

Bowing Wall Repairs

Bowing walls refer to walls that have developed a noticeable inward or outward curve. This condition is typically caused by excessive soil pressure, poor drainage, or hydrostatic pressure against the foundation. Bowing walls can be a sign of foundation problems and should be addressed promptly to prevent further structural damage or potential collapse.

Foundation Piering Mississauga

Foundation piering, also known as foundation underpinning, is a method used to stabilize and support a sinking or settling foundation. It involves installing steel piers deep into the ground beneath the foundation to transfer the weight of the structure to more stable soil or bedrock. The piers are driven or drilled into the ground until they reach a stable stratum, providing support and preventing further settlement of the foundation.

Cut Off Wall Installation Mississauga

Cut-off walls are a construction technique used in foundation repair to prevent water intrusion and stabilize the soil. They involve excavating a trench around the foundation and installing a vertical barrier, typically made of concrete or a waterproofing material. This barrier blocks the flow of water into the foundation, reduces hydrostatic pressure, and helps maintain the stability of the soil, effectively repairing and protecting the foundation from water-related damage.

Sticking Windows & Doors Repairs

Sticking windows and doors can be related to foundation damage as the shifting or settling of the foundation can cause misalignment of the frames. This misalignment can result in doors and windows becoming difficult to open or close smoothly. It is a common symptom of foundation issues and should be addressed to ensure the stability and functionality of the structure.

What Our Clients Say?


Stephanie G.

Residential Client

I used Aquamaster for two separate home waterproofing projects and I was extremely satasified with their work and price. Their team are highly skilled, thorough and were able to complete the 10.5 hour job in one day. They were even kind enough to seal my window frame after I noticed a minor leak. I would highly recommend Aquamaster for all your waterproofing and plumbing needs.

The Aquamaster team is absolutely fantastic! They went above and beyond to diagnose and correct the problem that I had with my basement plumbing caused by old pipes and persistent tree roots. I used them once in 2012 and in 2020. I cannot say enough good things about this team - Highly recommend.
