The specific method used to level an old house depends on the type of foundation and the extent of the damage, and addressing underlying issues like drainage is critical for long-term success.

Why Old Houses Become Unlevel

Before diving into the details of how to level an old house, it’s important to understand why old houses become unlevel in the first place. Over time, various factors contribute to foundation shifts and structural problems, which are especially common in older homes.

1. Natural Settling Over Time

All houses settle over time, but this process can be more pronounced in older homes. As the ground beneath the foundation compresses and shifts, parts of the foundation may settle unevenly. This natural settling process can lead to sloping floors, cracked walls, and other structural issues that indicate the house is no longer level.

2. Shifting Soils

In regions like the Texas Gulf Coast, where the soil is rich in clay, expansive soil movement can cause significant foundation problems. When the soil gets wet, it expands, and when it dries out, it contracts. This constant expansion and contraction can cause the foundation to shift, leading to an unlevel house.

3. Aging Structural Materials

Old houses were often built with materials that weaken over time. Wooden beams and floor joists, for example, can warp, sag, or decay, leading to uneven floors. In addition, older masonry or concrete foundations may crack or crumble, causing sections of the house to settle unevenly.

4. Water Damage

Water is one of the most significant contributors to foundation issues in old houses. Poor drainage systems, leaking pipes, or water pooling around the foundation can erode the soil beneath the house, leading to settling and an unlevel structure. In coastal areas like the Texas Gulf Coast, where heavy rainfall and moisture are common, this is a frequent issue.

How to Level an Old House: A Step-by-Step Guide

Leveling an old house requires a careful and methodical approach to ensure the structure is stabilized without causing further damage. Here’s a step-by-step guide to leveling an old house, covering everything from inspections to the final touches.

1. Conduct a Thorough Foundation Inspection

The first step in leveling an old house is to assess the condition of the foundation. A professional foundation expert will inspect the home to identify the areas that need leveling and determine the underlying cause of the foundation problems.

What Happens During a Foundation Inspection?

Checking for Cracks: The contractor will look for cracks in the foundation, walls, and floors, which indicate that the house has settled unevenly.
Measuring Floor Slopes: The inspector will use tools like a laser level or water level to measure how much the floors have sloped or settled over time.
Assessing Water Damage: Any signs of water damage or drainage issues around the foundation will be noted, as this is a common cause of foundation problems in old houses.
Examining Structural Components: Wooden beams, joists, and other structural elements will be examined to check for rot, warping, or damage.

This inspection helps determine the extent of the foundation issues and the best method for leveling the house.

2. Determine the Best Method for Leveling

Once the foundation inspection is complete, the next step is to choose the appropriate method for leveling the house. Different methods are used depending on the type of foundation (pier and beam or slab) and the severity of the problem.

Common Methods for Leveling an Old House:

Hydraulic Jacking: For pier and beam foundations, hydraulic jacking is often the go-to method. This involves placing hydraulic jacks under the house to lift it back to its original level. Additional supports, such as concrete blocks or steel piers, are installed to keep the house stable after lifting.
Steel or Helical Piers: If the foundation has shifted due to soil movement, steel or helical piers may be used. These piers are driven deep into the ground until they reach stable soil, and the house is then lifted and anchored to the piers to prevent future settling.
Concrete Pilings: For slab foundations, concrete pilings may be installed to lift and stabilize the house. These pilings are driven deep into the ground to provide long-lasting support for homes that have settled unevenly.
Slabjacking or Mudjacking: For minor foundation issues, slabjacking may be used. This process involves injecting a grout mixture beneath the slab to lift it back into place.

3. Prepare the House for Lifting

Before any lifting can occur, the house must be properly prepared. This includes clearing any debris or obstacles around the foundation, ensuring access to key areas, and placing the necessary equipment, such as hydraulic jacks or piers, in position.

Steps in Preparing the House:

Clear the Area: Any landscaping, furniture, or debris near the foundation will need to be removed to allow for safe access to the house.
Install Temporary Supports: Temporary supports may be placed under the house to ensure that it remains stable during the lifting process.
Set Up Hydraulic Jacks or Piers: Depending on the method used, hydraulic jacks or piers will be strategically placed under the house to prepare for lifting.

In older homes, particular care must be taken to ensure that the structure can withstand the lifting process without causing further damage.

4. Lift the House Carefully

Once everything is in place, the actual lifting process can begin. Using hydraulic jacks, the house is slowly and carefully lifted back to its original level. This process must be done gradually to prevent any sudden shifts that could damage the structure.

How the Lifting Process Works:

Slow and Steady Lifting: The house is lifted in small increments, often just a fraction of an inch at a time. This gradual approach helps prevent any cracks or stress on the structure.
Monitoring for Cracks: Throughout the lifting process, the house is closely monitored for any signs of cracking or movement that could indicate stress on the building.
Making Adjustments: As the house is lifted, adjustments are made to the jacks or piers to ensure that the house is being lifted evenly.

The lifting process can take several hours to several days, depending on the size of the house and the extent of the foundation issues.

5. Stabilize the Foundation

After the house has been lifted to the correct level, the next step is to stabilize the foundation to ensure that it stays level. This involves installing steel or concrete piers, reinforcing beams, or adding additional supports to prevent the house from settling again.

Methods for Stabilizing the Foundation:

Installing Steel Piers: Steel piers are driven deep into the ground and attached to the foundation to provide long-term stability.
Concrete Pilings: In slab foundations, concrete pilings are installed in a grid pattern beneath the house to support the weight of the structure and prevent further settling.
Reinforcing Beams and Joists: If the house has a pier and beam foundation, the wooden beams and joists may need to be reinforced or replaced to provide additional support.

Stabilizing the foundation is a critical step in the leveling process, as it ensures that the house remains level and prevents future structural issues.

6. Address Underlying Issues

Leveling an old house is just one part of the process. It’s equally important to address any underlying issues that may have caused the foundation problems in the first place. For example, poor drainage or water pooling around the foundation can lead to ongoing settling if not corrected.

Key Issues to Address:

Improve Drainage: Ensure that water is being directed away from the foundation. Installing gutters, downspouts, and French drains can help prevent water from pooling around the foundation.
Control Soil Moisture: In areas with expansive clay soil, managing soil moisture is essential. Watering the soil around the foundation during dry periods can help prevent excessive contraction, while proper drainage can prevent over-saturation during rainy periods.
Repair Leaks: Any plumbing leaks or water damage should be repaired to prevent future foundation problems.

Addressing these underlying issues helps ensure that the house remains level and stable long after the leveling process is complete.

7. Final Adjustments and Repairs

Once the house has been leveled and the foundation stabilized, the final step is making any necessary adjustments and repairs. This may include fixing cracks in the walls, adjusting doors and windows, and addressing any cosmetic issues caused by the foundation movement.

Final Repairs:

Patch Cracks: Any cracks in the walls, ceilings, or floors should be patched and repaired to restore the home’s appearance.
Realign Doors and Windows: Doors and windows that were misaligned due to the foundation settling will need to be adjusted to ensure they open and close properly.
Cosmetic Repairs: Any damage to the interior or exterior caused by the foundation movement should be repaired, including repainting walls or replacing trim.

After these final touches, the house should be level, stable, and ready to be enjoyed for many years to come.

Conclusion

Leveling an old house can be a complex process, but it’s essential for restoring the structural integrity of the home and preventing further damage. By following the steps outlined above—starting with a foundation inspection, choosing the right leveling method, lifting the house carefully, and stabilizing the foundation—you can successfully level your old house and keep it standing strong for years to come.

In regions like the Texas Gulf Coast, where soil conditions and moisture levels can cause foundation issues, addressing underlying problems like drainage and soil movement is critical for ensuring long-term success. With the right approach, you can preserve the charm and character of your old house while making sure it remains safe, stable, and level.
