Did your water bill double this month despite no changes in your routine? In Calabasas, where water tiers are aggressive and lots are expansive, a sudden cost increase is rarely an error. It usually signals a hidden water leak.
Whether it’s a fractured irrigation line or a pipe bursting under your foundation, locating the source fast is the only way to stop the financial bleeding.
3 Reasons Your Bill Is So High
Water doesn’t vanish; it escapes. Based on our local service calls, these are the top three offenders:
1. Slab Leaks (The Invisible Destroyer)
Most Calabasas homes sit on concrete slab foundations with copper piping running underneath. Over time, soil chemistry reacts with the copper, creating pinhole leaks. You won’t always see a puddle. Instead, look for:
- A “hot spot” on your floor.
- The sound of running water in a quiet house.
- unexplained dampness in carpets or wood flooring.
2. Irrigation System Failures
Your landscaping is likely the biggest water consumer on your property. A single broken sprinkler head or a cracked underground PVC line can unknowingly dump thousands of gallons into the soil. These leaks often hide because they occur underground or during early-morning timer cycles.
3. The “Silent” Toilet Leak
Never underestimate a worn-out flapper valve. A toilet that runs silently can waste up to 200 gallons a day. This constant flow keeps your meter spinning and drives up your utility costs 24/7.

The 5-Minute “Meter Test”
Confirm a leak before you call for help.
- Shut off all water inside and outside (faucets, dishwasher, washing machine, and irrigation).
- Locate your water meter (usually near the curb).
- Watch the dial. If the leak indicator (often a small triangle) is moving, water is escaping somewhere on your property.

If that meter is moving, you need professional Leak Detection. At LSP Plumbing, we use acoustic listening discs and thermal imaging to “see” through walls and concrete. We pinpoint the exact leak location before we drill, saving your expensive flooring and driveway from unnecessary destruction.

Local Cost Guide: Leak Detection & Repair
Because hidden leaks require a two-step process, costs are split:
- Step 1: Detection ($250 – $500): This covers the specialized equipment and labor to locate the issue non-destructively.
- Step 2: Repair (Varies): A simple pipe patch might cost $400, while jackhammering a slab or rerouting a main line often ranges from $1,500 to $4,000+.
