Hidden slab leaks under Fleming Island houses: repair and replacement
Slab leaks tend to give the same signs in Fleming Island as anywhere else in Clay County: a warm patch on the floor, a meter that moves with everything off, a rising bill or the sound of water when nothing runs. Each has other possible causes, and the visit is about ruling those in or out.
A water leak under the house is harder to spot on a slab than on a raised floor, because there is no crawlspace to look into. In Fleming Island, most under-slab leaks are first noticed at the meter, on the bill or in a change to the floor.
Professional leak detection in Fleming Island uses pressure tests, acoustic listening and thermal imaging to find the leak before any concrete is opened.
Fleming Island is one of 5 places we list in Clay County, alongside Green Cove Springs and Keystone Heights. In the northern part of the state the ground is less uniform, with sandy patches, clay and loam. Homes are a mix of slab and raised construction, and the first visit establishes which one you have.
Where Fleming Island came from
Fleming Island is an unincorporated community.
Irish immigrant George Fleming received a 1,000-acre Spanish land grant and founded the Hibernia plantation in 1790. In 1942 the U.S. Navy built four asphalt runways here as an outlying field for Naval Air Station Jacksonville. The old runways were demolished in the late 1990s to make way for new development.
Homes in Fleming Island were built across many decades, so a technician asks about the age of the house and its pipe material before choosing a test.
The setting of Fleming Island, Clay County
Fleming Island sits on the western side of the St. Johns River, off U.S. 17, about 21 miles southwest of downtown Jacksonville. Water or wetlands border it on every side: the St. Johns River to the east, Doctors Lake to the north, Black Creek to the south and Swimming Pen Creek to the west. Fleming Island's northern edge meets the town limits of Orange Park.
A wet patch or standing water around a home in Fleming Island does not by itself point to a slab leak, which is why testing comes before any digging.

What happens on a leak visit in Fleming Island

Safe checks for Fleming Island owners
Ten minutes at home can save time when the technician arrives in Fleming Island.
Turn everything off. Close every tap, stop the washing machine and dishwasher and pause the lawn sprinklers before you look at anything else. This applies to your Fleming Island home too.
Notice the floor. Warmth underfoot, damp baseboards or the sound of water in a quiet house are all things to write down. This applies to your Fleming Island home too.
Look back at the bills. Two or three months of rising charges with no new pool, guests or watering is worth pointing out. This applies to your Fleming Island home too.
Check the meter box. Look at the small flow indicator for a few minutes. Any movement is a reason to call. More on the water meter leak check page. Do this at your Fleming Island home before calling.
Call with your notes. Tell the person on the line what the meter did, which rooms are affected and how long it has been going on. That is all a Fleming Island dispatcher needs to start.
