Water Leak Detection Services

A hidden leak can damage your home long before you see the source. Malek’s licensed plumbers use professional diagnostic equipment to pinpoint water loss, explain what the testing reveals, and help you understand the right next step—without unnecessary cutting or excavation.

PROFESSIONAL LEAK DETECTION

Pinpointing Hidden Leaks Without Unnecessary Damage

Hidden leaks do not always leave an obvious puddle. Changes in your water usage, pressure, flooring, or walls may be the first indication that water is escaping somewhere it should not.

Slab Leak Detection

Locate suspected leaks in water lines running beneath your home’s concrete foundation.

Underground Water Line Leaks

Identify leaks affecting buried water service lines between the meter and your home.

Leaks Behind Walls or Ceilings

Trace concealed plumbing leaks that may be causing stains, moisture, or unexplained damage.

Hot and Cold Water Line Leaks

Test pressurized supply lines to determine which part of the plumbing system is losing water.

Fixture and Connection Leaks

Check plumbing connections near toilets, sinks, showers, water heaters, and other fixtures.

Hard-to-Find Plumbing Leaks

Investigate unexplained water loss, pressure changes, damp areas, or unusually high water bills.

WARNING SIGNS

Signs You May Need Professional Leak Detection

Hidden leaks do not always leave an obvious puddle. Changes in your water usage, pressure, flooring, or walls may be the first indication that water is escaping somewhere it should not.

An unexplained increase in your water bill

The sound of running water when fixtures are off

Damp, warm, or discolored areas on floors

Water stains or bubbling paint on walls or ceilings

Musty odors or recurring mildew

Low or fluctuating water pressure

Cracks developing in walls, flooring, or the foundation

Your water meter continues moving when no water is being used

A Warning Sign Does Not Always Confirm a Leak

Professional testing helps determine whether a leak is present and narrow down its location before walls, flooring, or landscaping are opened unnecessarily.

WHY LEAKS DEVELOP

Common Causes of Plumbing Leaks

Plumbing leaks can develop for several reasons, from aging pipes and excessive water pressure to shifting soil and failed connections. Identifying the cause helps determine the most appropriate repair.

Aging or Corroded Pipes

Older water lines may weaken, corrode, or develop pinhole leaks over time.

High Water Pressure

Excessive pressure places added strain on pipes, fittings, valves, and fixture connections.

Loose or Failed Connections

Joints, seals, and supply-line connections can loosen or deteriorate and begin leaking.

Foundation Movement

Shifting soil or foundation movement can place stress on pipes beneath or entering the home.

Damaged Underground Lines

Tree roots, soil movement, excavation, and normal deterioration can damage buried water lines.

Poor Installation or Materials

Improperly installed plumbing or defective materials may fail earlier than expected.
