Frequently Asked Questions About Foundation Repair

What are the signs of foundation problems?

Common signs include visible cracks in walls or foundations, uneven or sloping floors, doors and windows that stick or won't close properly, separating trim, gaps where walls meet the ceiling or foundation, and chimney leaning.

How much does it cost to repair a foundation?

The cost of foundation repair can vary significantly, ranging from a few hundred dollars for minor crack repairs to tens of thousands for major structural stabilization. Factors influencing cost include the severity of the damage, the type of repair needed (e.g., piering, underpinning), the size of the home, and your geographic location.

What is the difference between foundation repair and waterproofing?

Foundation repair focuses on stabilizing and strengthening the structural components of your home's foundation to address issues like settlement, bowing, or cracking. Waterproofing focuses on preventing water from entering your home, typically through the basement or crawl space, using methods like drainage systems, sealants, and membranes. Often, these services go hand-in-hand, as water intrusion can cause foundation problems, and foundation cracks can allow water to enter.

Are foundation repair warranties transferable?

Many companies offer warranties on their foundation repair work. Some of these warranties are transferable to new homeowners if you decide to sell your property, which can be a valuable selling point. It's crucial to inquire about the specifics of the warranty, including its duration and transferability.

What is helical piering?

Helical piers are steel shafts that are screwed into the ground to provide a stable foundation base. They are often used to stabilize or lift existing foundations that have settled. They are a popular choice due to their minimal impact on the surrounding landscape during installation.

What is push piering?

Push piers, also known as resistance piers, are hydraulically advanced into the ground to support stable soil or bedrock. They are effective for lifting and stabilizing foundations that have settled due to soil consolidation or erosion. They are installed through the foundation footing.

When should I call a professional foundation repair company?

You should call a professional foundation repair company as soon as you notice any signs of potential foundation problems. Early detection and repair can prevent minor issues from becoming major, costly damages. Don't hesitate if you see cracks, water intrusion, or other structural concerns.

Can I repair my foundation myself?

Minor cosmetic repairs, like sealing small hairline cracks with caulk, might be DIY-able. However, significant structural issues such as settlement, bowing walls, or major cracks require professional assessment and repair. Attempting complex repairs without the necessary expertise and equipment can exacerbate the problem and lead to more expensive repairs later.

How do I choose the best foundation repair contractor?

Look for companies with a proven track record, experienced and certified technicians, positive customer reviews, and comprehensive service offerings. Get multiple quotes, ask for references, and ensure they provide detailed explanations and a solid warranty. Licensing and insurance are also critical factors.

What are the most common foundation problems?

The most common foundation problems include settlement (sinking), soil expansion (heaving), hydrostatic pressure (water pushing against the foundation), and poor construction or material quality. These can all manifest as cracks, leaning, or water intrusion.

What does "underpinning" mean in foundation repair?

Underpinning is a method used to strengthen or deepen the foundation of an existing building. It typically involves extending the foundation downwards or outwards to reach more stable soil or bedrock, or to resist forces that are causing settlement or instability.
