Causes of Foundation Cracks in the Region
In Lewisville, the primary drivers are:
- Soil expansion and contraction due to seasonal temperature swings.
- Waterlogged soils from heavy rainfall or inadequate drainage.
- Settlement from uneven load distribution.
Signs You Need Repair
Homeowners should look for:
- Visible cracks wider than ¼ inch or that grow over time.
- Uneven floors, doors that jam, or gaps around windows.
- Water stains or dampness near the foundation.
Repair Options and Techniques
Professional services typically offer:
| Method | When to Use | Pros |
|---|---|---|
| Concrete Injection | Hairline or small cracks | Fast, minimal disruption |
| Underpinning | Large separations or settlement | Provides long‑term support |
| Stone Mastic Sealer (SMS) | Water infiltration issues | Creates a waterproof barrier |
Choosing a Reliable Service Provider
Key criteria:
- Local licensing and insurance verified through the Texas Department of Licensing.
- Positive reviews on Google and HomeAdvisor.
- Detailed, written estimate and warranty.
Costs and Insurance Coverage
Typical repair costs range from $1,200 for injection to $5,000 for underpinning, depending on crack size and depth. Some homeowners' insurance policies cover foundation repairs if they result from sudden, accidental damage, but routine settlement repairs usually do not. Consulting with an insurer before hiring a contractor can clarify coverage.
Maintenance to Prevent Future Cracks
Preventive steps include:
- Installing proper drainage and gutters.
- Keeping the soil around the foundation slightly damp, not saturated.
- Regular inspections, especially after heavy rains.
When to Call a Professional
If cracks exceed ¼ inch, show movement, or are accompanied by water damage, professional assessment is essential. DIY fixes may mask symptoms but fail to address underlying causes, potentially leading to costly structural failure later.
