What is Crawl Space Repair?
Why Sanibel needs Crawl Space Repair.
Sanibel sits on layered marine deposits, shell beds, and a shallow water table, with Hurricane Ian (2022) storm surge plus annual rainy-season saturation working on it year-round. Post-storm slab voids and slow footing displacement are still surfacing across Lee and Collier counties.
Local conditions: Sanibel soil & climate.
Soils. Pure barrier-island sand with localized layers of organic muck and shell beds. Bearing depth is variable.
Water table. Very shallow — often 2–3 ft, plus salt-water intrusion year-round.
Climate stressors. Direct Gulf hurricane exposure. Hurricane Ian made landfall as a Cat 4 here; the island was evacuated for months.
Local challenges. Almost every pre-Ian structure on the island has been evaluated for hidden settlement. Many homes look fine but have slab voids or shifted footings that won’t show until weight loads change.
Typical building stock and dispatch. 1960s–80s beach cottages on shallow concrete pilings, plus modern stilt-construction rebuilds since Ian.
How we install Crawl Space Repair in Sanibel.
Three years after Ian, Southwest Florida is still finding hidden settlement — voids beneath slabs that didn’t fail at landfall but have since.
Our 4-step process — same protocol on every Sanibel project.
- Free on-site inspection. Licensed specialist evaluates the structure, takes elevation readings, and identifies the root cause — at no cost.
- PE-stamped design. Our staff Professional Engineer specifies pier count, depth, torque, and capacity — sealed for permitting in your jurisdiction.
- Certified install. Partnered with Patriot Foundation Systems and Foundation Systems Supply crews drive each pier to a documented torque-to-capacity matching the design.
- Lift, load test, warranty. Hydraulic lift to target elevation, signed load test to confirm capacity, lifetime structural warranty issued same day.
