Under-slab leak repair and replacement in Eustis

A leak under a concrete floor rarely announces itself in Eustis. The clues are indirect: the meter, the bill, a floor that feels different and sometimes a sound in a quiet room. Concrete is only opened once tests have shown where the water is going.

Callers in Eustis use several names for one problem: slab leak, foundation leak, water under the house. For a home on a concrete floor it usually means a supply or drain pipe leaking beneath it.

Slab leak detection in Eustis is non-invasive: the technician tests, listens and measures from above the floor, and opens it only once the leak is located.

Eustis is one of 11 places we list in Lake County, alongside Clermont and Fruitland Park. The middle of the state has sandy soil, many lakes and a lot of irrigation. Because outdoor water use is high, a moving meter is tested against the sprinklers before anyone looks under the floor.

A short history of Eustis

Eustis was established in 1883.

Eustis is one of several Lake County towns dating to the 1870s, when settlers moved south into the Florida frontier. Eustis is named for Abraham Eustis, an early U.S. Army commander in Florida, by way of Lake Eustis. A railroad reached the area in 1880 and lake steamers connected it to nearby lakeside towns. By the early 1900s it was a winter vacation spot.

Homes in Eustis were built across many decades, so a technician asks about the age of the house and its pipe material before choosing a test.

Where Eustis sits

Eustis sits on the eastern shore of Lake Eustis, one of the Harris Chain of Lakes, in Lake County. US 441 is a main route through the area.

In Eustis, outdoor water such as sprinklers and rain can look like a leak under the house, so a technician tests the lines first.

What is under the slab in Eustis

Homes in Eustis vary in age, and age is the first clue to the plumbing. Housing runs from older slab homes to recent builds, plus many rentals and vacation homes. Newer homes often use PEX supply lines. See irrigation and outdoor leaks.

Housing and pipes in Eustis

Eustis has homes from more than one building period, so any of copper, the gray plastic pipe used from the late 1970s to the mid 1990s and PEX may be in the walls and floor.

Most houses are single-family and slab built, which puts the supply runs to the kitchen, baths and laundry under the floor.

Eustis was incorporated in 1883 and covers about 10.9 square miles in Lake County. Houses from different building periods stand side by side, so slab plumbing varies from street to street.

Hearing a water leak under the house

Listen in a quiet house at night for a faint hiss, trickle or hum. It is easiest to hear in a hallway or bedroom with the air conditioning off, and it can seem to come from the floor or a wall.

An ice maker filling, a toilet refilling or pipes expanding can sound alike. The test is the main valve: if the noise continues with it closed and then stops, a supply line is involved, and a pressure test can confirm it.

Testing hot and cold sides separately

To find the losing line, hot and cold supplies are closed and tested separately, and the house is isolated from the street side of the meter.

If only the hot side loses pressure the search shrinks at once toward the water heater and the hot runs in the floor; if the cold side drops, the same logic applies to the cold runs.

The leak detection visit in Eustis

In Eustis, the technician starts with your account of the problem and the home's age, reads the meter with the water off and tests the lines one at a time. Pinpointing comes last, followed by a plain explanation of repair choices and cost.

Copper under Florida slabs

Many Florida slab homes from the 1960s to the 1990s have copper pipe running through or under the concrete. It lasts a long time, though years against concrete and local water can thin it in places.

Failure usually shows up as a pinhole, a tiny steady leak that is easy to miss until a bill or a warm patch gives it away. When the pipe is uncovered, the technician describes the condition of the copper.

PEX tubing in recent construction

Slab homes built more recently often use PEX, a flexible plastic tube. It does not corrode and is run in long lengths with few joints, which suits a slab.

A PEX leak is usually at a fitting or where the tube was bent too far or rubbed during building. Pressure tests and listening still find it, and the repair options match those for other pipe.

A home check before the call in Eustis

Before anyone drives out to Eustis, these checks tell you whether the meter is moving.

Do this firstA short home check
  1. 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 Eustis home too.

  2. Scan the statements. An unexplained increase that repeats each month is typical of a hidden leak.

  3. Walk the floors. Feel for a warm patch on tile or slab, press along baseboards for softness and listen for a faint hiss or trickle. Do this room by room in your Eustis home.

  4. Look at the flow indicator. Most meters have a small dial that spins when water moves. If it turns while everything is off at your Eustis home, read the water meter leak check guide and call.

  5. Give us a call. Bring the reading, the rooms and a rough date, and the call goes quickly.

Common questions

How do I check for a slab leak in Eustis?

Turn off all water use and watch the meter for a few minutes. A moving dial or low-flow indicator suggests a leak somewhere. Then look for warm floor spots and listen for running water. The same is true in Eustis.

Does a high water bill in Eustis mean a slab leak?

Possibly, though a worn toilet flapper or a damaged sprinkler can push a bill up just as far. Bills also rise because of a toilet flapper or a broken sprinkler, which is why the meter and some simple checks come first. The same is true in Eustis.

In Eustis, does PEX under a slab ever leak?

Yes, usually at fittings or where the tubing was kinked or rubbed during building. It is not leak-proof, but it does not corrode the way metal can. This is how it works for Eustis callers.

In Eustis, what equipment is used?

The equipment is pressure gauges, acoustic listening gear and thermal imaging. The technician explains which are used and why, and says how confident the result is. This is how it works for Eustis callers.

In Eustis, what if I want to think about the options?

Take the time. Detection on its own is a valid visit, and the findings are yours to take away. A reputable technician does not rush the decision. The same is true in Eustis.
