Pier and Beam Foundation Repair

Many homes built before 1960 are built on pier and beam foundations. Sometimes these foundations are called “block and base” foundations but they are a little different. Both were very common construction methods before concrete slab (slab on grade) foundations became popular with home builders. The two earlier foundations include a “crawl space” – the space between the home / structure and the ground. We also offer pier and beam or block and base foundation repair.

What is a Pier and Beam Foundation?

A pier and beam foundation generally uses three major components. First, concrete pads are placed at ground level. Then concrete blocks are placed on top of the concrete pads. The last component is the concrete foundation beam, which is built around the perimeter of the house or structure. These concrete beams are necessary for homes and structures that have heavier brick and stone siding because they have a greater load capacity. This comprises the pier and beam foundation.

Block and Base foundations are very similar except they do not have concrete foundation beams around the perimeter. In general they are more suitable for homes or structures that are built with lighter siding, such as wood or aluminum.

Pier and Beam Foundations are sometimes referred to as "block and base".

Warning Signs of Pier and Beam Foundation Problems

The most common warning sign of a pier & beam foundation problem is usually a floor problem. It may be bowing or sinking in places, slanting in one direction, or showing floor gaps or other damage. Or it could be creaking excessively. But the warning signs are not limited to the floor.  Below is a short list of items that commonly alert the homeowner about a foundation issue with this type of foundation.

  • Floors – bowing / sinking, sagging, flexing with weight
  • Floor coverings – tiles that crack, wooden floors with gaps, creaking
  • Interior Sheetrock Cracks – indicates movement
  • Doors / Windows – stick or won’t open and close properly – indicates movement
  • What are some of the Advantages and Disadvantages of Pier and Beam Foundations?

Failures of Pier and Beam Foundations

When support is lost it can lead to cracked support beams and additional damage to the frame of the house.

Clay soils that expand and contract will also shift horizontally and diagonally, leading to a loss of support for the home foundation.
Cracked Beams are a serious problem and can lead to serious damage to other portions of the house.
Clay soils that settle will lead to the loss of support for the beams of a pier and beam foundation.
Moving and shifing clay soils can created settlement and loss of support for pier and beam foundations.


Advantages of Pier and Beam Foundations

  • More Stability in Clay Soils when constructed with drilled piers that reach stable soil
  • Lower Repair costs – Crawl space allows easy access to foundation components, wiring, and plumbing

Disadvantages of Pier and Beam Foundations

  • More complex and expensive to build than concrete slab foundations
  • Cold weather can freeze drain pipes
  • Lack of ventilation can lead to musty smells
  • Susceptible to termites, rodents, wood rot, and mold
  • Flooring costs can be higher
  • Flooring tends to flex, which leads to creaky floors

Cost of Pier and Beam Foundation Repair

The good news for homeowners is that the cost of pier and beam foundation repair is generally much lower for pier and beam versus concrete slab foundations. The primary reason for this cost difference is that pier and beam foundations have easier access to the areas needing repair. In addition, they also have lower labor costs and require less equipment. However, there are exceptions and those usually include homes with narrow crawl spaces.

Homeowner Problems And Comments

A 6 inch difference in elevation from the front to the back of the house is not normal. A foundation inspection is needed.

The difference in elevation from the front of the house to the back is abnormal.  It could be settlement in one area, or upheaval in another area, or both.  Regardless, this house needs to be inspected and leveled.



A house that is only 5 years old should not be having these warning signs of foundation problems. The homeowner should contact the builder and an independent structural engineer.

This house is ONLY 5 years old and is showing multiple warning signs of foundation problems.  The window glass broke because the frame was being “squeezed” by the movements of the foundation and framing.  The home owner should contact the builder for their evaluation and/or repair.  If the owner is not satisfied with the builder’s response he should hire an independent structural engineer and a lawyer.



When the interior beams are not making contact with the concrete blocks then the homeowner should take immediate action.

If the home owner’s diagnosis is correct, then this would be a relatively easy and inexpensive pier and beam foundation leveling job.



Warped floors are an indication that the pier and beam foundation is in need of leveling and/or repair.

Warped floors are more than a warning sign – it is direct evidence of a pier and beam foundation problem.  An immediate inspection is needed.



Standing water in the crawl space indicates either poor drainage or a plumbing leak. Regardless, corrective action should be taken.

Standing water under the house is a serious problem.  It is usually due to poor drainage or a plumbing leak.  Hopefully it is a plumbing leak because they are relatively easy to repair with these types of home foundations.



The sagging and non-level floors should be corrected with a professional leveling job.

Sagging and unlevel floors are definitely evidence of a foundation problem.  The most common cause is settlement of the clay soils.



The homeowner is correct, concrete posts are stronger and more durable than wooden posts and should be replaced.

Concrete columns, posts, and beams are stronger and more durable than wood.  And termites don’t eat concrete.  However, wood does have more flexibility.



Settling of clay soils will cause part of a pier and beam foundation to sink lower in relation to other parts of the house.

The homeowner has stated that he has seen settling.  Usually a re-level is a fairly easy  solution.
