Slab Leak Detection & Repair in Orlando

Licensed Master Plumber. Serving Orlando Since 1997.

Most Orlando homes are built on concrete slab foundations with water lines running directly beneath them. When one of those lines fails, the leak is invisible from the surface, and the damage builds quietly. Mercury Plumbing has handled slab leak detection and repair across the greater Orlando area since 1997, serving single-family homes, multi-family communities, apartment complexes, and commercial properties. We carry full licensing, insurance, performance bonds, and BBB A+ accreditation, and we come equipped with video inspection equipment to locate the problem before any floor gets opened.

Precise location is the difference between a targeted repair and unnecessary structural damage. We don’t guess at where a leak is hiding.

Call Mercury Plumbing at (407) 315-1187 for an over-the-phone estimate or to schedule service. We’re available 24/7, including same-day and emergency appointments.

Why Orlando Property Owners Call Mercury Plumbing

Our founder, Tom Murphy, entered the plumbing trade as an apprentice at 18 and has been a licensed master plumber ever since. That depth of experience shapes how we approach every slab leak job, including the ones other plumbers have already attempted and couldn’t resolve. We take on difficult and tricky problems, and we have a track record of resolving issues where others haven’t.

We keep stocked, radio-dispatched service vans on the road around the clock. When a slab leak surfaces at an inconvenient hour, we’re already moving. For larger jobs, we provide no-charge on-site estimates in addition to over-the-phone consultations. Flexible financing options are available to help manage the cost of more extensive repairs.

Warning Signs of a Slab Leak

Because the damaged pipe is buried beneath the foundation, slab leaks rarely announce themselves directly. The signs are indirect, and they’re easy to dismiss until the damage compounds.

Watch for any of the following:

Unexplained increase in your water bill with no change in usage
Sound of running water when every fixture in the building is off
Warm spots on the floor pointing to a hot water line leaking below
Damp or wet flooring with no visible surface source
Musty or mildew odor rising from floors or walls
Cracks appearing in flooring, walls, or ceilings as the slab shifts
Drop in water pressure throughout the property

Any one of these can have other explanations, but two or more appearing together is a strong signal that something is wrong beneath the slab. Professional detection equipment is needed to confirm the source and pinpoint its location.

Slab Leak Repair Options in Orlando

We start with detection. Using video inspection equipment and other diagnostic tools, we locate the leak precisely before recommending any repair. That step determines which approach makes the most sense given your property’s pipe condition, layout, and the extent of the damage.

Depending on those findings, repair options may include:

Direct slab access: Opening the floor above the leak to replace the damaged pipe segment directly
Pipe rerouting: Bypassing the buried line entirely by running a new line through the home’s framing, often using PEX tubing
Epoxy pipe lining: Sealing the interior of a damaged pipe without excavation when the pipe is otherwise intact
Full repiping: Replacing an aging or extensively compromised pipe system when isolated repairs aren’t the right long-term answer

We tailor the repair to the situation rather than defaulting to the most invasive or least invasive option. An unaddressed slab leak can erode soil beneath the foundation, promote mold and moisture intrusion, and drive up water bills month after month.

What Causes a Slab Leak

A slab leak occurs when a pipe running beneath or encased within a home’s concrete slab foundation develops a crack, hole, or joint failure. Because the pipe is hidden from view, the failure can persist for weeks or months before surface-level signs become obvious.

Common causes include:

Pipe corrosion: Older copper pipe systems are vulnerable to chemical reactions with water over time, especially in areas with specific water chemistry profiles
Soil movement: Ground shifting or settling beneath the foundation places stress on buried pipes at connection points and bends
High or fluctuating water pressure: Chronic pressure spikes accelerate wear on pipe walls and joints
Abrasion: Pipes running against concrete or gravel can wear through gradually from friction
Age-related deterioration: Any pipe system has a service life, and older installations carry higher failure risk

In Central Florida, seasonal rainfall and soil moisture fluctuation contribute to ground movement beneath foundations. That ongoing cycle adds cumulative stress to buried pipe systems, particularly in homes with aging infrastructure. Even a slow, small leak can erode soil and contribute to foundation movement if it goes unaddressed.

How Professional Slab Leak Detection Works

Locating a slab leak without the right equipment means guessing, which typically leads to unnecessary demolition without finding the source. Professional detection uses a combination of tools designed to identify the leak non-invasively before any floor work begins.

The process typically involves:

Electronic amplification: Acoustic detection devices pick up the sound signature of water escaping under pressure, even through several inches of concrete
Electromagnetic pipe locating: Traces the path of buried pipes to map the system before narrowing the search zone
Video inspection equipment: Camera systems that travel through the pipe to identify damage location and condition from the inside
Pressure testing: Isolates the affected line to confirm a leak is present and distinguish which section of pipe is compromised

Accurate detection narrows the repair to a defined area rather than a broad zone, which directly limits the scope of any floor or slab work required and keeps disruption to a minimum.
