Mold in a Pasadena home rarely stays where you can see it. In the city’s older housing stock — Craftsman bungalows in Bungalow Heaven, historic homes near Old Town, hillside properties in Linda Vista and Hastings Ranch — mold thrives in the hidden spaces: wall cavities fed by slow plumbing leaks, crawl spaces that never fully dry, and enclosed corners with no airflow. RestoKleen Restoration provides IICRC-certified mold remediation throughout Pasadena as part of our mold remediation services across Los Angeles County. Our headquarters is a short drive away on Foothill Blvd in Glendale. Every job starts with a free inspection, and we respond within 60 minutes of your call, 24 hours a day. CSLB #1047297.

Pasadena Mold Remediation Case Study: Kitchen Wall Mold from a Refrigerator Supply Line
Our Mold Remediation Process
Inspection & Moisture Mapping
Every job starts with a free inspection. We inspect the affected area and use moisture meters to find the full extent of the problem, including hidden moisture inside walls and crawl spaces where mold grows undetected.
Containment
We seal the work area with polyethylene barriers and negative air pressure using HEPA-filtered air scrubbers, preventing spores from spreading to clean parts of your home during removal.
Removal
Contaminated drywall, insulation, and materials are carefully removed and bagged under containment for proper disposal. Salvageable surfaces are HEPA-vacuumed and prepared for treatment.
Antimicrobial Treatment
Every exposed surface is treated with EPA-registered antimicrobial solution, eliminating remaining spores at the source rather than masking them.
Drying & Restoration
Commercial dehumidifiers and air movers run until moisture returns to baseline. Once moisture readings are back to normal, we can rebuild the area and put your home back the way it was.
Signs of Mold in Your Pasadena Home
- Musty, earthy odor that cleaning doesn’t fix — often the first sign
- Visible dark spots on walls, ceilings, grout, or inside cabinets
- Water stains, warped flooring, or recent leaks that were never professionally dried
- Appliance lines and hidden plumbing — refrigerator supply lines, dishwasher connections, and ice maker lines are among the most common hidden mold sources we find
- Allergy or asthma symptoms that improve when you leave the house
Smell something musty near the fridge, the dishwasher, or under a sink? Call (833) 675-5336 or send us a message and we’ll come out for a free inspection. Dealing with a leak or water damage too? See our restoration services in Pasadena, or read how refrigerator water line leaks cause hidden mold.

FAQ
How much does mold remediation cost in Pasadena?
It depends on how far the mold has spread and what has to be removed. A small area inside one closet wall costs far less than mold that has climbed a whole wall cavity, like the kitchen project on this page. We inspect for free and give you a written estimate before any work starts.
How long does mold remediation take?
Most homes take 3 to 7 days from setting up containment to the final dry-out. Bigger jobs, or jobs where walls need to be rebuilt, take longer. You get a timeline after the inspection, before we start.
Can mold really spread from an appliance line?
Yes. Refrigerator supply lines, dishwasher connections and ice maker lines run behind cabinets, where a slow leak can drip for months without anyone seeing it. The Pasadena kitchen project on this page started with exactly that: a leaking refrigerator supply line that fed mold from the crawl space almost to the ceiling inside the wall.
Can mold grow in the crawl space under my house?
Yes. Many older Pasadena homes sit over crawl spaces, and a crawl space that stays damp gives mold a dark, hidden place to grow. If there’s mold in a wall above it, we check the crawl space too and treat it as part of the same job, because mold left below the floor can grow back into the wall.
Do you test for mold?
No. We don’t do laboratory mold testing. We inspect, find the moisture source, and remove the mold. If you want a lab test, an independent tester can do that before or after our work.
Do you serve all of Pasadena?
Yes. All of Pasadena, from Old Town to Bungalow Heaven, Hastings Ranch and Linda Vista, plus the nearby San Gabriel Valley. Our headquarters is a short drive away in Glendale and we’re available 24/7. Call (833) 675-5336 to confirm service to your address.
