Why foundation problems are so common in Orlando
Orlando's deep sandy soils have virtually no clay, but the underlying limestone karst creates Florida's worst sinkhole corridor. Excessively drained sand means rapid moisture loss around foundations in dry spells. Heavy summer thunderstorms then saturate the sand, creating a buoyancy effect on shallow footings.
50.7" of annual rainfall means the soil around foundations is frequently saturated, increasing hydrostatic pressure and creating conditions for persistent heave.
The median home in Orlando is 36 years old with post-tension or conventional slab-on-grade foundations. After decades of seasonal soil movement, even well-built foundations begin showing distress — sticking doors, drywall cracks, and uneven floors.

Get a structural engineer inspection first ($300–$780) before committing to any repair. A PE works for you, not a contractor, and will give you an unbiased assessment of what actually needs to be fixed.

What to do about foundation problems in Orlando
1. Check your symptoms
Walk through your home — check for sticking doors, cracks above door frames, uneven floors, and gaps between walls and ceilings. In Orlando's Candler Fine Sand soil, these can appear gradually or suddenly after weather changes.
Is my crack serious?2. Get a PE inspection
A licensed Professional Engineer ($300–$780) works for you, not a contractor. They'll measure floor elevations, document crack patterns, and tell you if you actually need repair — or if it's just cosmetic.
Engineer vs. contractor3. Get competitive bids
If repair is needed, get 3+ bids from licensed contractors in Orlando. Compare method, pier depth, warranty terms, and whether they'll follow the engineer's recommendations. Expect $1,800–$6,500.
What questions to askOrlando foundation repair questions
Orlando's deep sandy soils have virtually no clay, but the underlying limestone karst creates Florida's worst sinkhole corridor. Excessively drained sand means rapid moisture loss around foundations in dry spells. Heavy summer thunderstorms then saturate the sand, creating a buoyancy effect on shallow footings. Despite low clay content (4%), Orlando's primary foundation risk is sinkhole activity from the underlying limestone karst, combined with hydrostatic pressure from the high water table. With a median home age of 36 years, many foundations have decades of cumulative movement.
Most foundation repairs in Orlando cost $1,800–$6,500, depending on the severity of damage and repair method. Sinkhole remediation — common in Florida — can cost $10,000–$100,000+ depending on the size and depth of the void, which is separate from standard foundation repair. For non-sinkhole issues, crack repair starts at $250–$800, and underpinning runs $1,500–$4,000 per pier. Always get a structural engineer inspection ($300–$780) before committing to any repair plan.
Most homes in Orlando (median year built: 1990) have post-tension or conventional slab-on-grade foundations. Florida foundations are typically shallow slab-on-grade or monolithic slab due to the high water table. Basements are extremely rare. Repairs often involve compaction grouting for sinkhole-related settlement, or helical piers driven through sandy soil to limestone bedrock.
Watch for these signs: doors or windows that stick or won't latch, visible cracks wider than 1/4 inch (especially diagonal cracks above door frames), uneven or sloping floors, and gaps between walls and ceilings or floors. In Florida, also watch for circular crack patterns in the ground, depressions in the yard, or trees/fence posts that are suddenly tilting — these can indicate sinkhole activity beneath your home. A structural engineer can give you a definitive assessment for $300–$780.
