Signs that point to mold
None of these proves mold, but together they build a strong case for inspection.
- A musty, earthy smell that is strongest in one room or a closet.
- Dark, green, white or fuzzy patches on walls, ceilings or around windows.
- Paint that bubbles, cracks or peels without a clear cause.
- Stains that spread or return after cleaning.
- Warped baseboards, soft drywall or cupped flooring.
- A history of leaks, floods or roof repairs that were not dried quickly.
Where mold hides
Mold likes damp, still, dark places. Common hiding spots are behind bathroom walls, under sinks, inside closets that share a wall with a bathroom, above ceiling tiles near roof edges and behind furniture pushed against outside walls.
Check the backs of cabinets, the inside of air vents and the area around windows that collect condensation. Use a flashlight and look for staining, bubbling or a damp feel, not just visible mold.
A simple walk-through
Do this in daylight with a flashlight. It takes about half an hour.
- Smell each room. Note where a smell is strongest, then check that spot closely.
- Inspect wet areas. Look under sinks, around toilets, behind washers and around tubs and showers.
- Check ceilings and corners. Stains or soft spots may point to roof, plumbing or HVAC leaks above.
- Check windows. Look for condensation, peeling paint or dark growth at the frames.
- Note the history. Write down past leaks, floods or repairs, with dates.

Test for a hidden plumbing leak
A hidden leak feeds mold without any visible water. Golden State Water, which serves Culver City, says you can check for leaks by reading your meter. Turn off all water inside and around your home, then watch the meter. If it keeps moving, you likely have a leak, such as a leaky toilet or faucet.
The utility also says the two most common causes of higher than normal bills are irrigation issues and possible leaks, so a jump in your bill is a clue worth following. Leaks beyond the meter are the property owner's responsibility, so call a plumber if the test shows movement.
Clues and next steps
Match what you notice to a sensible next step.
| Clue | What it suggests | Next step |
|---|---|---|
| Musty smell, no visible source. | Hidden moisture | Moisture check and inspection. |
| Dark patch on drywall. | Surface or hidden growth. | Inspect, find source, consider removal. |
| Meter moves with everything off. | Plumbing leak | Call a plumber. |
| Bubbled paint near a shower. | Water behind the wall. | Open and inspect. |
| Mold after a flood. | Materials stayed wet. | Call for mold remediation and drying. |
When to test and when to call a crew
Testing can show what is present and how much, and it is a separate service from removal. If you plan to sell or refinance, a lender or buyer may ask for testing, and nobody can promise how they will respond.
If you find growth, a persistent smell or a leak history, call a crew. The mold remediation page explains the inspection and removal process, and water damage cleanup covers wet materials that need removal. Health questions belong to a physician.
How seasons and routines hide mold
Mold signs change with the season. In cooler months, closed windows trap humidity from showers and cooking, and condensation can collect on cold walls. In warmer months, air conditioning can drip or sweat on ducts in attics and closets.
A simple routine catches most problems. Run bathroom fans during and after showers, wipe window frames when they fog, empty drip trays and check under sinks quarterly. These habits cost little and prevent the damp that mold needs.
Quick checks you can do this weekend
Each takes only a few minutes.
- Smell the closet that shares a wall with the bathroom.
- Press on the drywall below windows to feel for softness.
- Look inside the cabinet under the kitchen sink.
- Check the ceiling below an upstairs bathroom.
- Read the water meter before and after an hour of no use.
Using Culver City utility information
Golden State Water lists a toll-free customer line at 1-800-999-4033 for meter-reading questions. It says its crews maintain lines only up to the meter. That tells you where your responsibility starts, which is useful when a leak test shows a moving meter.
If your leak test is clean and the smell persists, look at condensation, roof leaks and air conditioner drains. The service areas page lists our coverage, and the Marina del Rey page covers the coastal side, where a different water system applies.

Signs of mold: questions from Culver City homeowners
Yes. A musty smell can come from hidden growth. A moisture check and inspection can find the source.
Turn off all water use inside and outside, then watch the meter. If the needle keeps moving, you likely have a leak, according to Golden State Water.
No. Dirt, soot and stains look similar. Inspection or testing can tell.
Testing answers a different question from removal. Ask a crew or an independent tester what fits your situation.
A plumber, because Golden State Water says leaks beyond the meter are the owner's responsibility.
