Foundation crack repair — fix the cause, not the surface.

A foundation crack is the visible end of an underground problem. Surface patches buy you weeks; the crack reopens because the soil under the footing is still moving. Our crack repairs start with diagnosing why the crack appeared, then specifying the structural fix that stops it permanently.

Crack types we diagnose

Not every crack is structural. We classify each one and recommend the right level of intervention:

  • Stair-step cracks in brick or block — almost always differential settlement
  • Diagonal cracks at door or window corners — structural movement
  • Horizontal cracks in foundation walls — soil pressure or footing failure
  • Vertical cracks wider at top — heaving, often from expansive clay
  • Vertical cracks wider at bottom — sinking, often from sand washout or sinkhole
  • Hairline cracks — usually cosmetic, but worth tracking
When a crack is structuralIf your crack is wider than a dime, growing, or paired with sticking doors and sloping floors, the soil under the footing is moving. Cosmetic patching alone will fail.

Why foundation cracks keep coming back

If you’ve patched a crack and it reopened, the underlying soil hasn’t been addressed. Common causes in Florida:

  • Soil settlement from karst voids or sand washout
  • Expansive clay heave/shrink cycles in inland counties
  • Tree-root water absorption near footings
  • Drainage failure saturating soil under the slab
  • Vibration from nearby construction or heavy traffic

How we repair structural cracks

First, we stop the underlying soil movement with helical piers — driving them to bearing strata under the footing on either side of the crack. Once the structure is stabilized, we hydraulic-lift back toward level.

Only THEN do we close the crack with epoxy injection or hydraulic cement. This sequence is the difference between a permanent fix and a re-crack within 18 months.

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.

When is a foundation crack serious enough to call a professional?

Three triggers: any crack wider than a dime (~1/16"), any crack that’s actively growing month over month, or any crack paired with sticking doors, sloping floors, or new drywall cracks at corners. Hairline cracks under those thresholds are usually cosmetic concrete shrinkage and can be monitored.

Why do patched foundation cracks keep reopening?

Because the patch addressed the symptom — the visible split — not the cause, which is soil movement under the footing. If the soil keeps moving, the structure keeps moving, and the patch either reopens at the same location or a new crack appears nearby. A permanent crack fix has to stop the soil movement first; only then does the patch hold.

Can I inject epoxy into a foundation crack myself?

For a hairline cosmetic crack in a non-structural location, yes — DIY kits work. For any crack that’s structural (wider than a dime, in a bearing wall, paired with movement symptoms), injecting epoxy without addressing the soil cause locks the crack at its current width and the structure cracks somewhere else next. The diagnosis matters more than the product.

Are vertical foundation cracks more serious than horizontal ones?

It depends on where they appear. A vertical crack in a poured wall that’s wider at the top usually means heaving (clay swelling, uplift). Wider at the bottom usually means sinking or sand washout. Horizontal cracks across the middle of a basement or foundation wall are lateral pressure — almost always structural and usually urgent. We classify each crack pattern during the inspection.

How long does foundation crack repair take?

Pure crack-injection work is a one-day scope per crack. When the crack indicates structural movement and helical piers are part of the fix, the full repair sequence is 2–4 working days: pier install, lift, then crack closure and any cosmetic finish work.

Will my homeowners insurance pay for foundation crack repair?

Generally only if the cause is a covered peril — most often sinkhole activity in Florida. Cracks from normal settlement, drainage, or tree roots are typically excluded. We document the cause during inspection so the engineering report is available if you do file a claim.

"Our 1980s ranch had stair-step cracks down both ends of the brick. Solid Foundations sent an engineer first, designed the fix, and the helical crew was in and out in three days. Cracks closed up. Doors swing right again. Worth every penny."

"Pasco County karst situation under our pool deck. Their geotech probe found a void at 18 feet that the previous quote missed. They specified deeper helicals to clear it — about 20% more than the cheapest bid but it was the only one that actually addressed the cause. Two years in, zero movement."

"They’re our local guys — Lake City based, and you can tell when something’s their home turf. PE knew exactly which neighborhoods had which karst profile before he even drove out. Quote came back the next morning, install was a week later."
