Wind-Driven Rain Intrusion St. Petersburg, 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.

Often needed alongside
- Humidity & Moisture Drying
When the outdoor air is wetter than the building, opening windows adds water. Drying means a closed building and conditioned air.
- Storm Surge & Tidal Flooding
Surge and tidal water rise from the ground up and carry salt and silt with them. Anything porous they soaked is treated as contaminated.
Frequently asked questions
Why do the crank-out windows in an older St. Petersburg apartment drip?
More than a quarter of St. Petersburg homes are in buildings of ten or more units. Where one of the late 1960s still has crank-out awning windows, their gaskets harden over time, and the closed sash no longer seals. Outdoor air seeps in onto the metal frame, which the cooled room has chilled, and water beads on it and runs into the sill and the wall below. New gaskets stop the seepage.
What holds up the ground under the bluff-top houses of Roser Park?
Concrete block walls. In 1914 the neighborhood's developer walled the ravine banks along Booker Creek, 5 to 6 feet high, to keep the soil beneath the houses above from subsiding, and some sections were later rebuilt as concrete slab walls. Through August, rain soaking into the bluff behind those walls drains only slowly through or under them, so the ground at the houses' creek-side foundations stays wet.
How does the floor of a garage apartment behind an older St. Petersburg house get damp?
In Roser Park most houses have an outbuilding, usually a garage apartment, garage or shed, built at the same time and of the same materials. A garage apartment's floor is the garage's ceiling. With the apartment cooled, the underside of that floor runs colder than the humid summer air in the garage below, and water condenses on it and soaks into the boards. Insulating and sealing the garage ceiling keeps that air away.
