What Largo's homes say about water damage
In Largo, more than half homes were built before 1980, and about one in ten before 1960. That age matters. Galvanized steel supply lines from that era corrode from the inside, and cast-iron drains can crack along the bottom where you can't see them.
Before anything else, find the main shutoff and make sure it turns. Old gate valves often seize or break when they are finally needed.
Most homes in the area sit on concrete slabs, so water from a leak spreads sideways under flooring and into walls rather than draining away. It can soak carpet pad, laminate and the bottom of drywall several rooms from where it started.
About 25% of homes here are manufactured or mobile homes. Leaks in these homes often run into the underbelly, where insulation holds water against the floor. A restoration company should open and dry the belly, not only the carpet you can see.
Leaks under manufactured homes soak insulation and subfloors before they are noticed.

If water is coming in right now
- Stop the water. Close the valve at the fixture, or the main shutoff for the house.
- Make it safe. Cut power to wet rooms at the breaker only if you can reach the panel without standing in water.
- Protect what you can. Lift furniture off wet carpet with blocks or foil under the legs, and pull rugs off the floor so they don't stain or trap water.
- Photograph it, then get drying started. Photos come first for insurance; drying should begin the same day. Our first 24 hours guide has the full checklist.
Where the main shutoff usually is
Most Pinellas homes have the main shutoff on the outside wall near where the line enters, with the meter near the street.
If the water came from a toilet, a sewer line or outside, treat it as contaminated: see sewage backup cleanup or flood water cleanup.

Water damage questions from Largo
How quickly does water damage need to be dried in Largo?
Start within 24 to 48 hours; the EPA says materials dried in that window are much less likely to grow mold. Humid air around Largo shortens that window, so don't wait for a dry day.
Why do older homes in Largo have so many hidden leaks?
With more than half homes in Largo built before 1980, a lot of original galvanized supply pipe and cast-iron drain line is still in service. Both corrode slowly and tend to leak at joints inside walls and under floors, where water spreads before anyone sees it.
