Hidden leaks waste water and rot framing quietly for weeks before anyone sees a stain. When the signs are active, such as water dripping from a ceiling or pooling in a crawlspace, treat it as an emergency and call the 24/7 line. A licensed plumber can usually be booked for the same day when availability allows.
While you wait, shut off the main water valve if water is visible, turn off power to wet areas and move valuables. Then call (805) 249-7135 and tell us what you saw, where and when you first noticed it.
Signs of a hidden leak, in the order people notice them
Meter still moving
Close every tap and appliance. If the meter dial or low-flow indicator keeps turning, water is escaping.
High water bill
A bill well above your normal month with no change in habits is a classic leak sign.
Wet ceiling or wall
Brown stains, bubbling paint or soft drywall mean water has been traveling inside the wall.
Warm floor or spot
A warm patch on a slab can mean a hot water line leaking underneath.
Low pressure
A sudden drop with no city outage can point to a leak on the supply side.
Musty smell
A damp, closed-in smell with no visible source is worth checking.
Many people start the call with a symptom, not the word leak, and that is fine. Describe what you see and we will work out the method.
How we find the leak without tearing things open
Detection starts with isolation. We shut off sections of the system to see which segment holds pressure and which loses it. That narrows a house-wide mystery to a single wall, slab or yard run.
From there, acoustic listening equipment hears the hiss of pressurized water, thermal imaging shows cool or warm patterns behind drywall and moisture meters confirm what the camera suggests. For drain lines, a sewer camera confirms cracked pipe. When the source turns out to be a slab, slab leak repair is the next step.
Meter spinning? Treat it as a leak emergency
Call the 24/7 line. We will tell you what to shut off and book a detection visit.
Meter test: the five-minute check you can do first
Most homes have a water meter in a box near the curb or property line. Turn off every fixture, ice maker and irrigation timer. Read the meter, wait fifteen minutes, then read it again without using water. Any change means a leak somewhere past the meter.
The City of Lompoc's water division takes reports of suspected leaks on the city side of the meter. Anything after the meter is the owner's side, which is where our work begins. Yard and meter-box leaks, such as a failed fitting beside the box, are a common find on that stretch.
Ceiling, wall, crawlspace and buried-line leaks
Where the leak lives changes how we approach it. A ceiling leak under a bathroom is often a drain or shower pan. A wall leak may be a supply line behind a fixture. Under-house leaks in crawlspaces show up as damp insulation, rusty straps or sagging subfloor.
Buried supply lines between the meter and the house can leak for months before the soil surfaces. Irrigation lines are a separate system and a frequent source of high bills in yards and flower beds. If pool or spa plumbing is involved, tell us on the call so we send the right tools.
Once the leak is found, repair options range from a single fitting to a section of pipe. If the pipe is failing everywhere, repiping is the lasting answer.
Lompoc water and why pinhole leaks happen
The city's 2025 water quality report shows a pH near 8.4 and average hardness near 293 ppm. Hard water leaves scale that can hide small leaks until a fitting fails, and older copper and galvanized lines still develop pinholes over time. Mineral crust around a joint is often the first visible clue.
We note that the city's lead and copper testing in 2025 found no sites over the action levels. That speaks to the water supplied to the home, not the condition of your own interior pipe.
What to do while you wait for a leak detection visit
- Close the main valve if water is visibly spreading, then note the meter reading.
- Do not cut into walls or floors yourself, because the wet spot is often not the source.
- Turn off power to any wet outlet only if the panel is dry and easy to reach.
- Photograph stains, warm floor spots and meter readings with the time.
- Keep a record of recent water bills to show the plumber.
What affects the price of leak detection
Many homeowner policies cover resulting water damage but not the cost of finding the leak itself, so check your policy and keep photos. Call (805) 249-7135 for your price before work starts.
Replacement pipe after a leak is found follows the California Plumbing Code (Title 24, Part 5, 2025 edition, effective January 1, 2026), which is based on the Uniform Plumbing Code (UPC). According to the City of Lompoc building division, simply fixing a leak does not need a permit, while rerouting lines does.
Leak Detection questions, answered
Yes. The 24/7 line takes active leak calls any hour. A licensed plumber is booked the same day when availability allows.
Compare it to your normal months. Then do the meter test with every tap off. If the meter moves, there is a leak somewhere past the meter.
Usually not. Detection narrows the location first, so any opening is small and targeted.
Yes. Acoustic and thermal methods work through slabs, and crawlspace leaks are found by inspection. See slab leak repair for the repair side.
The City of Lompoc is responsible for its side. Report it to the water division. Anything after the meter is the owner's responsibility.
Yes. Irrigation leaks are common behind high bills in yards. Tell us on the call so we scope the visit correctly.
