When it comes to residential construction, the foundation is probably the most important part of a house’s structure. Pier and beam foundations are common, particularly in older homes throughout our area. Understanding how it works—and what its benefits are—can help homeowners make informed decisions about maintenance, repairs, or even purchasing a new home.
What Are Pier and Beam Foundations?
A pier and beam foundation is made up of vertical piers (typically concrete, brick, or stone) that support horizontal beams. These beams then support the wood floor joists and subfloor of the house. This form of foundation raises the home off the ground, resulting in a crawl space beneath.
Advantages of Pier and Beam Foundations
One of the primary advantages is accessibility. The crawl space beneath the home provides simple access to plumbing, electrical systems, and HVAC components, making repairs and upgrades less invasive and less expensive. Additionally, pier and beam foundations function better in our area due to our expansive clay soil, which tends to shift and crack concrete slab foundations.
Finally, in terms of comfort, pier and beam homes often have more “give,” providing a slightly softer feel underfoot than concrete slabs.
Maintenance Tips for Pier and Beam Foundations
If your home has a pier and beam foundation, routine inspections are essential. Look for dampness or signs of pests in the crawl space, as well as cracks in walls or stuck doors, which can indicate foundation instability. Proper drainage around the property can also help to extend the life of the foundation.
