Water Leak in Columbia, MD

In most Columbia homes, the main shutoff is inside the house near where the water line enters (often basement, crawl space, or utility closet). Some homes have a secondary shutoff at the street (meter box). Know where yours is BEFORE an emergency.

Simple fixture leaks: $100-$300. Pipe repair behind walls: $500-$1,500 (includes drywall access and patching). Slab leaks: $2,000-$6,000. Water line replacement: $1,500-$5,000. Costs increase significantly if water damage restoration is needed.

Most policies in MD cover sudden water damage (burst pipe, appliance failure). Gradual leaks (slow pipe corrosion, long-term seepage) are typically excluded. The repair itself (fixing the pipe) is often not covered — just the resulting damage.

Signs of a hidden leak: rising water bill, water meter spinning with all fixtures off, musty smell, mold or mildew, warm spots on floors (slab leak), or stains on walls/ceilings. Plumbers in Columbia use electronic leak detection to pinpoint hidden leaks without demolition.
