Alliance Home Improvement offers foundation repair services that combine structural engineering principles with practical, cost‑effective solutions for residential properties. Their process starts with a detailed site assessment, followed by a recommendation of the most suitable repair method—whether piering, slabjacking, or carbon‑fiber reinforcement—based on soil conditions, foundation type, and the severity of settlement.

Assessment and Diagnosis
The first step is a comprehensive inspection that includes visual checks for cracks, uneven floors, and door/window misalignment, plus laser level measurements to quantify settlement. Alliance may also employ soil testing to determine moisture content and bearing capacity, which influences the choice of repair technique.
Common Repair Methods
Pier Installation
Concrete or steel piers are driven or drilled into stable soil layers beneath the foundation and then jacked to lift the structure back to its original position. This method is preferred for homes with significant settlement or when the underlying soil is expansive.
Slabjacking (Mudjacking)
A grout mixture is pumped under a settled concrete slab, filling voids and raising the surface. Slabjacking is efficient for minor settlement issues and typically less disruptive than piering.
Carbon‑Fiber Reinforcement
High‑strength carbon‑fiber strips are bonded to the interior or exterior of foundation walls, increasing load‑bearing capacity without extensive excavation. This technique is often used when wall cracks are the primary concern.
Cost Considerations
Pricing varies by method, house size, and local labor rates. Pier installation can range from $1,200 to $3,500 per pier, while slabjacking usually costs $5 to $12 per square foot. Carbon‑fiber reinforcement is typically $10 to $20 per square foot. Alliance Home Improvement provides a written estimate after the initial assessment, outlining material, labor, and any permit fees.
Timeline and Disruption
Most repairs are completed within 1–3 days for slabjacking, 2–5 days for pier installation, and up to a week for extensive carbon‑fiber work. Alliance schedules work to minimize interior disruption, often sealing off work zones and protecting flooring.
Warranty and Follow‑Up
Alliance offers a warranty that covers structural integrity for a minimum of five years, with longer terms for specific methods like piering. Homeowners receive a post‑repair inspection report and recommendations for moisture management to prevent future settlement.
Choosing the Right Contractor
When evaluating foundation repair providers, consider licensing, insurance, and client testimonials. Alliance Home Improvement maintains a portfolio of completed projects and can supply references upon request.
