You can check your meter, test toilets with food coloring in the tank and look for damp spots. Finding leaks under slabs or inside walls requires specialized equipment. That is where professional detection saves time and money.
Older galvanized steel pipes are prone to corrosion, and some older polybutylene pipes are known for premature failure. However, even modern materials like copper or PEX can leak due to improper installation, high water pressure or foundation movement.
Common signs include a sudden spike in your water bill, damp spots on walls or floors, mildew odors, visible mold growth, the sound of running water when no fixtures are in use, or a continuously running water meter even when all water is off.
Most residential leak detection appointments take one to three hours. Larger homes, commercial buildings or multiple leaks can take longer. We give you an time estimate when we schedule.
