Six signs your foundation is sinking
Sinking presents differently than other foundation problems — the structure is going DOWN, not just shifting:
- A noticeable drop where slab meets driveway, sidewalk, or patio
- Floors that visibly slope toward one corner
- New gaps between walls and ceiling, or around window/door frames
- Doors and windows that suddenly stick, jam, or won’t latch
- Stair-step cracks running diagonally through brick or block walls
- Exterior cracks wider than a dime, especially near corners
Why Florida foundations sink
Sinking is almost always a soil problem, not a footing problem. Five Florida-specific drivers:
- Karst limestone dissolving and forming voids beneath the slab
- Expansive clay shrinking dramatically in dry seasons
- Hurricane saturation reducing bearing capacity for weeks
- Sandy coastal soils washing out from under footings
- Shallow water table softening the bearing zone year-round
Stopping the sink permanently
A helical pier reaches BELOW the failing soil layer to load-bearing strata. Our crews drive each pier to a documented torque, then hydraulic jacks lift the structure back toward level. The load now transfers around the failing soil, not through it. Lifetime structural warranty.
What you can expect — typical timeline.
- Free inspection & quote — within 3 business days of your call
- Engineer-stamped design — 5–7 business days after acceptance
- Permit pulled and crew scheduled — 1–2 weeks (varies by county)
- Installation — typically 2–5 days for a residential project
- Lift, load test, warranty issued — same day as install completion
Frequently asked questions
Common questions we hear during the free inspection. If yours isn’t covered, call 866-398-9323 — we’ll answer it.
How fast does a sinking foundation get worse in Florida?
It depends entirely on the cause. Sand washout from a single major storm can drop a slab ½″–1″ in days. Karst-driven settlement is typically slower — measurable in months. Sinkhole activity can be either, with no warning. The rule we use: if you’ve measured more than ½″ of drop in less than 12 months, treat it as accelerated and call us this week, not next month.
How do I measure if my foundation is actively sinking?
A long level or a laser level across the slab in 8–10 ft spans will tell you whether floors are out of level. To confirm active movement (not just pre-existing), mark a couple of crack widths with a pencil and a dated note — if they widen over 30–60 days, it’s active. Bring those readings to the inspection and the PE can move faster on a fix.
What kind of foundation pier stops sinking in saturated soil?
Helical piers carry full design capacity in saturated soil — the helical flights engage dense bearing strata below the saturated zone, and the galvanized shaft isn’t affected by groundwater. Push piers and concrete drilled shafts struggle here because they rely on shaft friction in soil that’s lost cohesion. This is why our Jacksonville and SW Florida designs are almost always helicals.
Can a sinking foundation be lifted back to original level?
Usually yes, partially or fully. After helicals are seated to bearing, hydraulic jacks at each pier location lift the structure in controlled ½″ increments. We can typically recover 60–95% of original elevation depending on how long the structure has been settled and how brittle the framing materials are. The PE makes the call on lift target based on structural condition — sometimes “stop the movement at current elevation” is the right answer.
Is sinking foundation damage covered by Florida homeowners insurance?
If the cause is sinkhole activity, generally yes — sinkhole coverage is required to be offered on Florida policies. If the cause is normal settlement, drainage failure, or tree roots, generally no. We document the cause with our PE and the engineering report is what insurers accept for coverage determination.
How much does sinking foundation repair cost?
Most residential helical pier scopes run $1,200–$2,500 per pier installed, depending on depth and access. A typical 6–10 pier job covers a single failing wall or slab corner. Whole-house pier scopes for severe settlement are bid by scope, not per pier. The free inspection includes a written quote so you can compare directly.
