What Is a Pier and Beam Foundation?

These foundations use a system of brick, stone, or concrete piers combined with wooden beams and joists to support your home above the ground. This design creates a crawl space, allowing easy access to plumbing, electrical systems, and foundation components for maintenance and repairs.

Types of Pier and Beam Foundations

There are two main types of foundations with understructures:

  • Pier and Beam: Includes a perimeter grade beam for added stability.
  • Block and Base: Does not include a perimeter grade beam.

Our Pier and Beam Foundation Repair Services

Every Pier and Beam foundation is unique, and the best repair method depends on the extent and type of damage. At Master Builders, Remodelers & Guaranteed Foundation Repairs, we start every project with a comprehensive foundation evaluation for soil movement, wood condition, and structural alignment. Based on our findings, we’ll recommend the right combination of repairs to restore strength, stability, and uniformity to your home.

Wood Beam, Joist, or Subfloor Replacement

Over time, wood components in a Pier and Beam foundation can weaken due to moisture, dry rot, or insect infestation. Damaged beams and joists can cause uneven or sagging floors, creaking, and structural instability. Our team replaces compromised wood with treated lumber designed to resist future decay and moisture intrusion. In cases where subflooring has softened or buckled, we can also replace or reinforce the subfloor to restore a solid, even surface throughout your home.

Re-Setting and Re-Shimming the Understructure with Steel Shims

As North Texas soils expand and contract with moisture changes, Pier and Beam foundations can shift, causing sloping floors or gaps around doors and windows.

To correct this, we re-set and re-shim the understructure by carefully adjusting each pier and beam connection. We use durable steel shims to replace old or deteriorated wood shims, providing a longer-lasting and more stable foundation adjustment. This precise process ensures your home is properly supported.

Moisture Management and Crawl Space Ventilation Improvements

We evaluate the crawl space for signs of moisture and can install foundation vents, crawl space fans, or vapor barriers to maintain balanced humidity levels and airflow. Proper ventilation not only protects the wood structure but also improves indoor air quality and helps maintain consistent temperatures inside your home.

Crawl Space Ventilation and Maintenance

Proper ventilation is essential to protect your foundation from future damage. Moisture is one of the biggest threats to pier and beam foundations. Without enough airflow, moisture can build up beneath your home, leading to wood rot, mold growth, and structural deterioration.

We install foundation vents and crawl space fans to regulate moisture and extend the life of your foundation.

Installing a vapor barrier is one of the most effective ways to protect your crawl space. A vapor barrier is a durable plastic liner placed over the soil beneath your home to block ground moisture from rising into the structure.
