Call 225-320-5566 to schedule leak detection in Mandeville.

Find Hidden Water Leaks Before They Cause More Damage

A hidden plumbing leak can remain beneath flooring, behind a wall, underground or below a concrete slab before the source becomes obvious.

Water may also travel away from the actual plumbing failure. The place where you see moisture is not necessarily where the leak began. Professional leak detection helps narrow down the source while reducing unnecessary demolition and guesswork.

Locating the leak quickly can help limit additional damage and give you the information needed to determine the appropriate plumbing repair.

Locating the Leak Is the First Step

Once the source of a hidden leak is identified, you can make a better decision about the repair that needs to be made.

Louisiana Leak Detection helps homeowners, businesses, plumbers and property managers identify difficult-to-find water problems so the affected plumbing can be addressed efficiently.

Depending on what is discovered, the next step may involve plumbing repair, additional investigation or evaluation of building materials affected by water.

Has the Hidden Leak Caused Water Damage?

A hidden slab or plumbing leak can allow water to spread beneath flooring, behind drywall, into cabinets, insulation and other building materials before the source is discovered.

Finding and repairing the plumbing problem stops the source of the water, but materials that are already wet may still require professional evaluation, drying or restoration.

If water damage is discovered, Louisiana Leak Detection can help coordinate the appropriate next steps so the source of the leak and resulting property damage can both be addressed.

If you notice wet flooring, damaged drywall, swollen cabinets, water stains or other visible property damage, mention it when you call.

Mandeville Leak Detection FAQs

How do I know if I have a hidden water leak in my Mandeville home?

Common signs include an unexplained increase in your water bill, running water sounds when fixtures are off, damp flooring, water stains, low water pressure, wet areas around the property or recurring moisture with no visible source.

Can you locate a slab leak in Mandeville?

Slab leak detection methods can help narrow down the location of plumbing leaks beneath concrete foundations and other difficult-to-access areas before unnecessary demolition begins.

Can you locate an underground water leak?

Underground water leaks may be suspected when there is unexplained water usage, reduced pressure, wet areas in the yard or moisture near the foundation. Leak detection can help identify the likely affected area.
