If you’ve noticed cracks in your walls, uneven floors, or doors that no longer close properly, your home may be experiencing foundation issues. These problems can be stressful, but the good news is that foundation repair is a well-understood process, and with the right guidance, you can make informed decisions.
In this comprehensive guide, we’ll walk you through everything you need to know about foundation repair, including the warning signs, causes, repair methods, costs, timelines, and how to choose the right contractor.
What Is Foundation Repair?
Foundation repair refers to the process of correcting structural issues in a building’s foundation. This can involve lifting and stabilising a sinking slab, reinforcing damaged piers and beams, or addressing soil-related issues causing movement.
Why it matters: A compromised foundation can affect your home’s structural integrity, reduce its value, and even become a safety hazard.
Common Signs Your Home Needs Foundation Repair
Early detection can save you money and prevent further damage. Look out for:
- Cracks in walls, ceilings, or floors
- Doors and windows sticking or misaligned
- Uneven or sloping floors
- Gaps between walls and ceilings or floors
- Moisture intrusion in basements or crawl spaces
- Separation around garage doors or chimney
- Exterior brickwork cracking
What Causes Foundation Problems?
Several factors can lead to foundation issues:
- Soil movement: Expansive clay soils common in Texas swell when wet and shrink when dry, causing movement.
- Poor drainage: Water pooling around the foundation can erode the soil.
- Tree roots: Roots from large trees can pull moisture from the soil, causing shifts.
- Plumbing leaks: Undetected leaks beneath the foundation can soften the soil.
- Poor construction: Inadequate footing design or substandard materials can cause early failure.

Foundation Repair Methods Explained
Different problems require different solutions. Here are the most common methods used by professionals:
1. Concrete Piers
- Installed under the foundation to stabilise and lift it.
- Best for heavy homes with deep foundation issues.
2. Steel Piers
- Driven deep into the ground until they reach stable soil or bedrock.
- More expensive but extremely durable.
3. Helical Piers
- Screw-like steel shafts ideal for lighter structures or limited access areas.
- Common in both new construction and repairs.
4. Mudjacking / Slabjacking
- Involves injecting a grout slurry beneath a sunken slab to lift it.
- Suitable for minor slab issues but not always permanent.
5. Foam Injection
- Expands quickly to lift concrete and fill voids.
- Lightweight, clean, and fast-curing.
DIY vs. Professional Foundation Repair
While small cosmetic cracks can be patched by homeowners, structural issues require a licensed foundation specialist.
DIY is appropriate for:
- Minor, hairline surface cracks
- Temporary water drainage fixes
Call a professional if you notice:
- Wide or expanding cracks
- Sagging floors or walls
- Persistent moisture or mildew
- Shifting door frames or windows
