Foundation Crack Repair — Frequently Asked Questions

What are the warning signs that my foundation needs crack repair?

There are several warning signs that your foundation may need professional crack repair. These include cracks in brickwork or masonry, gaps in floors or driveways, chimney cracks, cracks in basement walls, and sheetrock or drywall cracks on interior walls and ceilings. More serious warning signs include cracks that run from the basement floor to the ceiling, stair-step cracks in exterior masonry, and walls that bulge or bow outward. If you notice any of these signs, The Crack Guys offer free on-site inspections throughout Alabama and Tennessee so our experienced consultants can assess the situation right away.

What causes foundation cracks to form?

Foundation cracks most commonly form when the soil around or beneath your home changes. Soil movement from drought or erosion can cause the ground beneath your home to dry out or wash away, leaving the foundation without proper support and leading to uneven settling or shifting. Hydrostatic pressure is another major cause. When soil becomes saturated with water, it expands and pushes against your foundation until the concrete cracks. The Crack Guys’ experienced consultants will identify the root cause of your foundation cracks during a free on-site inspection in Alabama or Tennessee.

Why are foundation cracks dangerous even if they seem small?

Even a small foundation crack can let water inside your home, leading to moisture damage and mold growth. A crack smaller than a quarter of an inch can also give insects and pests an entry point. Beyond these concerns, cracks are likely a symptom of underlying foundation movement that, if left untreated, can compromise the structural integrity of your entire home. The Crack Guys encourage homeowners in Alabama and Tennessee not to wait. Schedule a free on-site inspection with our experienced consultants as soon as you notice any cracking.

How does The Crack Guys repair foundation cracks?

Depending on the cause and severity of the damage, The Crack Guys’ experienced consultants may recommend helical piers and/or slab piers (push piers) to lift and stabilize a settling foundation, or polyjacking (polyurethane foam injections for concrete lifting) to fill voids beneath a sinking slab and raise the concrete back into position. Our team will explain all available options during your free inspection.

What is polyjacking and when is it used for foundation crack repair?

Polyjacking is a repair method in which polyurethane foam is injected beneath a foundation slab to raise the concrete, fill voids, and seal cracks that have formed due to sinking or settling. It is a minimally invasive and highly effective solution for foundations and concrete surfaces that have sunk due to soil erosion, poor compaction, or other underlying issues. The Crack Guys’ experienced consultants will determine whether polyjacking is the right solution for your home during a free on-site inspection.

What are helical piers and how do they help with foundation repair?

Helical piers are steel supports that are screwed deep into stable soil beneath a settling foundation to lift it, level it, and prevent further movement. They act as stabilizers that transfer the weight of your home away from unstable soil and onto solid ground below. Helical piers are one of the most reliable long-term solutions for foundations that are cracking due to settlement or shifting. The Crack Guys’ experienced consultants can assess whether helical pier installation is the right solution for your home during a free inspection.

How soon should I address foundation cracks?

Foundation cracks should be addressed as soon as they are noticed. What starts as a small crack can quickly worsen as water infiltration, soil movement, and seasonal temperature changes put additional stress on the foundation. Delaying repairs often turns a relatively manageable problem into a much more costly one. The Crack Guys’ experienced consultants are ready to provide a free on-site inspection so you can act before minor damage becomes a major issue.
