Some foundation repairs are permanent, like underpinning and exterior drainage systems like the French drain. These fixes address the underlying problems—insufficient support from the soil and hydrostatic pressure on your foundation walls, respectively—so they can last for many decades, making them “lifetime fixes.” There are other solutions to address these issues that will last for up to a decade, making them temporary. These include slabjacking to raise concrete slabs back into place and dampproofing to reduce the water in the soil that interacts with the concrete foundation.

If your building department catches you or a contractor doing foundation work without proper permits, they will likely put the work on hold until you secure the necessary permits, which can cause delays of days or even weeks. You can also face violation charges for construction without a permit, which can cost hundreds, depending on where you live.

The average home foundation lasts between 80 and 100 years, but some can last much longer with proper maintenance and routine inspections. The lifespan depends on the foundation type, soil conditions, climate, and construction quality. Poured concrete walls can last up to 200 years, brick or stone foundations over 100 years, cement block foundations 80 to 100 years, and pier foundations about 75 years. Factors that can shorten a foundation's life include expansive clay soil, poor weather conditions, low-quality building materials, improper construction, and tree roots. Signs of damage include sloping floors, bowing walls, cracks, and doors or windows that stick.

Underpinning is a specific type of foundation repair where a specialist installs deep piers under a foundation to provide additional support. This method is often used when the soil beneath the foundation can no longer evenly support the structure. Foundation repair is an umbrella term that includes many methods. Besides underpinning, other common repairs include foundation crack repair, waterproofing, cosmetic repairs, and concrete block wall stabilization. Often, underpinning is accompanied by other work to address the root cause of the foundation issue, such as regrading the yard to ensure water drains away from the house.
