Foundation Crack Repair — Tallahassee, FL

What Causes the Wall to Split

Concrete is rigid. When the soil beneath it shifts, the foundation cannot bend, so it breaks. In Tallahassee, seasonal rainfall and drought are the main drivers of hydrostatic pressure and soil movement around homes. When the ground gets saturated, it swells and pushes against your foundation walls. When a drought hits, that same soil shrinks away, leaving the concrete unsupported.

We also see a lot of man-made issues contributing to this cycle. Improper grading and bad gutters can cause excessive moisture buildup near a foundation, leading to severe soil saturation problems. That trapped water creates immense pressure. Add in the constant humidity load that stresses building envelopes around here, and your foundation is fighting a constant battle. That is why our concrete foundation repair process always starts with looking at where the water is going before we ever look at the crack itself.

Reading the Fractures

Not all cracks mean your house is falling down. Hairline vertical cracks often happen right after a house is built just from the concrete curing. But when we see horizontal cracks, or cracks wider at the top than the bottom, we know the foundation is actively settling or bowing. Our crew looks at the whole picture. We check the grading, inspect the downspouts, and measure the floors inside to see how far things have dropped.

We do not just patch the crack and walk away. Slapping mortar over a structural failure is a waste of your money. True concrete repair services require stabilizing the structure first. If the soil is failing to hold the house up, we have to bypass that bad soil and anchor the home to something solid. That means bringing in heavy steel.

Driving Steel to Solid Ground

When a foundation needs to be permanently stabilized, we use helical piers. For most residential foundation crack repair jobs, we drive a helical pier with a 6-inch lead helix plate deep into the earth. The helix acts like a giant screw, pulling the pier down through the weak, saturated topsoil until it hits load-bearing strata. If we are dealing with lighter structural loads, like a settling porch or a small addition, we might use a round-shaft helical anchor instead.

We do not guess when the pier is deep enough. Our crew logs the torque-to-capacity correlation on every single helical pier install. The installation motor tells us exactly how much resistance the steel is meeting in the ground. When that torque reading matches the weight of your house, we know the pier can support the foundation. Only then do we attach the steel bracket to your footing.

The Lift and the Patch

Once the piers are driven and bracketed to the foundation, we can often lift the settled section of the house back toward its original position. We use hydraulic jacks to carefully raise the footing. This is a slow, controlled process. We record the hydraulic ram lift in 0.1-inch increments, watching the structure react to every adjustment. As the house comes up, you can often see the cracks in the brickwork or block walls close back together.

After the lift is complete and the weight of the house is permanently transferred to the steel piers, we address the cosmetic damage. We seal the cracks to keep out moisture and pests. Because the foundation is now resting on deep steel rather than shifting surface soil, those cracks will not reopen the next time Tallahassee gets a heavy rainstorm.

What Foundation Stabilization Costs

The cost of fixing a cracked foundation depends entirely on how much steel we have to put in the ground. We price this work based on the number of support points your house needs. For our installations, you can expect to pay $2500 to $3500 per helical pier installed.

A small corner settlement might only need two or three piers. A whole wall that has dropped could require six or more, spaced at specific intervals to properly distribute the weight. When we come out to inspect your property, we will map out exactly how many piers are required to permanently stabilize the structure. We give you a firm price for the complete job, including the excavation, the steel, the lift, and the final cleanup.
