Objective:
The aim of this blog is assist homeowners with detailed instructions, estimated expenses, and expert advice from Tru Integrity LLC that features the repairing, preventing, and identifying of foundation cracks for a stable living that lasts.
Step 1: Find Out the Type and Severity of the Crack
Not every crack is the same. It’s normal for hairline cracks to happen. But if you see any of the following, you need to do something right away:
- Cracks wider than 1/8 inch
- Water seepage or damp basement walls
- Horizontal cracks (often more serious)
- Doors and windows that stick
- Interior drywall cracks above doors
- Uneven floors
- Bowing or leaning walls
When these signs show up, the next step is to think about your options for foundation crack repair before the problem gets worse.
Step 2: Assess the Causes of Foundation Cracks
Shifting soil, too much water pressure, inadequate drainage, unstable backfill, or the natural settling of a home can all cause foundation cracks. Some cracks are not dangerous, but others may mean that the structure is moving.
Common reasons include:
- Clay soil that expands and contracts
- Water buildup caused hydrostatic pressure
- Bad grading or drainage
- Changes in temperature
- Settling of the concrete over time
Homeowners who put off repairs often have to pay more to fix foundation crack repair costs, especially when cracks widen or begin to leak.Check out our page on Foundation Crack Repair to find out more about how experts look at these problems.
Step 3: Decide If You Can DIY or Need a Professional
Some homeowners try DIY kits, but they usually only work for small cracks that don’t affect the structure. You need an expert to look at problems with water pressure, walls that are bowing, or structural movement.
- DIY kits are only suitable for minor cracks
- Cracks with water infiltration, structural movement, or wall bowing require expert assessment
- DIY fixes do not stop structural shifting and often fail over time

Step 4: Choose the Right Professional Repair Methods
The correct repair method depends on the crack type. Many homeowners search online for guidance on how to repair a crack in the foundation, but DIY solutions only work for very minor surface cracks.
Professionals use the following proven techniques:
1. Epoxy Injection (Structural Repair)
To put the concrete back together, epoxy resin is injected under pressure. This brings back its original strength. Best for structural cracks that need extra support.
2. Polyurethane Injection (Leak Repair)
The polyurethane foam expands inside the crack, making it watertight. Best for cracks that are wet or have active leaks.
3. Carbon Fiber Reinforcement
Carbon fiber straps are used to keep walls from moving and make them more stable. People often use this to make walls bend or move.
4. Exterior Waterproofing
This means digging up the outside foundation wall and putting in waterproof membranes and drainage systems.
5. Underpinning and Foundation Piers
Used to sink or settle foundations. Steel piers hold the structure up and steady it from below.

Step 5: Estimate the Costs to fix a crack in the foundation
One of the biggest questions homeowners ask is: How much does it cost to repair a cracked foundation?

- Minor crack sealing: $200–$600
- Epoxy/polyurethane injections: $400–$1,000

- Underpinning/foundation piers: $5,000–$20,000+
