Serving St. Augustine
Wind-Driven Rain Intrusion St. Augustine, FL
Wind pushes rain sideways through window frames, stucco and the base of the wall. The roof can hold and the house still take water. The walls on the side the wind came from are traced first, at windows, sliders, the base of the wall and the soffits. Block that took on water is dried from inside the closed building rather than left to the outdoor air.

Frequently asked questions
Why does salt water reach Davis Shores streets when it is not raining?
The city estimates that it sees tidal flooding 12 to 16 times a year. Davis Shores drains through about 21 outfalls into the Matanzas River or Salt Run, and on a high enough tide sea water enters those pipes, backs up and comes out into the streets. Driveways and garage slabs at street level are the first parts of a house it reaches.
What does tidal water leave behind in a St. Augustine garage?
Salt. When sea water from a tidal flood reaches a garage slab or driveway and then drains away, the salt stays in the concrete. Salt draws water out of humid air, so that concrete stays damp for weeks, and anything stored on it or against it takes up the moisture. Rinsing the slab with fresh water after the tide drops carries most of the salt out.
How does a summer power cut affect a closed St. Augustine house?
One St. Augustine home in seven is held for seasonal use. When the power fails, the cooling stops, and some systems do not start again on their own when it returns. From then on the closed house takes in the outdoor humidity with nothing removing it, and drywall, cabinets and fabric take it up. A thermostat that restarts the system by itself prevents this.
