What Causes Foundation Damage in Sanibel
Sanibel sits at sea level as a barrier island of loose, unconsolidated sand on the leeward side of Pine Island's more solid coral rock base — nearly half the island's total area is water. That sandy composition means soil underfoot is naturally soft and easily shifted, and the island's low elevation keeps the water table right at the surface almost everywhere. Add in the constant moisture from Gulf humidity, seasonal storms, and hurricane exposure, and Sanibel's soil rarely stays still under a foundation for long.
How We Fix It
Solid Foundations stabilizes settling foundations with steel piers, hydraulically driven down past the loose surface sand to load-bearing material below. Each pier is load-tested on site before the foundation is lifted and leveled, and every repair comes with a lifetime transferable warranty.

Is there a foundation repair company near me in Sanibel?
Yes. Solid Foundations is a licensed Florida General Contractor serving Sanibel, with free on-site evaluations.
What's the difference between foundation repair and foundation failure?
Foundation failure means the structure has moved enough to put the building's safety at risk — major cracking, severe sloping, or walls separating. Repair with steel piers addresses movement before it reaches that stage by stabilizing and lifting the foundation on load-bearing material.
How much does foundation repair cost?
Cost depends on the extent of the damage and how many piers are needed. Most residential jobs run from a few thousand dollars up to around $12,000. We provide a free, no-obligation estimate before any work starts.
Is Solid Foundations licensed?
Yes, we're a licensed Florida General Contractor, license CBC1267322.
What causes foundation problems specifically in Sanibel?
As a low-lying barrier island of loose sand sitting largely at sea level, Sanibel has a naturally high water table and soft, shifting soil beneath most structures. That combination, along with regular hurricane and storm exposure, is the main driver of foundation movement on the island.
