Fast, Reliable Mold Remediation Across North Hills
Mold remediation in North Hills costs between $1,800 and $6,500 for a typical single-story stucco ranch, with crawl space treatment running $900-$2,400 and full-home air quality restoration landing between $3,000 and $9,000 depending on square footage and how far the colony has spread. We can usually have a crew at your door within 90 minutes of your call, because Wade answers his own phone and doesn’t run calls through a dispatch center in another state.

Wade will tell you straight whether you need full Mold Remediation or just a moisture inspection.
Why Wade’s Restoration of California Is North Hills’s Preferred Mold Remediation Company
Wade Ferris has been crawling under North Hills homes since 2007, and the neighbors know it. Ask anyone on Sepulveda or Nordhoff about the restoration guy who shows up in the truck with his own name on the door and hands over a daily moisture log when the job’s done. That’s Wade. No call center, no subcontracted crew you’ve never met, no estimate that changes when a “project manager” shows up at your door. He publishes his address and license number, and he’s going to run into you at the hardware store on a Saturday, which matters more than any review count ever could.
North Hills homeowners call us because we know what’s behind these walls. The 1994 Northridge quake cracked the lath plane on thousands of homes here. Then somebody skim-coated over the cracks and sold the house. Thirty years later, those sealed voids are mold incubators. A national chain that sends a technician from Orange County doesn’t know to probe stucco corners on a 1962 ranch on Langdon Avenue. Wade does, because he’s been opening those walls since before half the flippers in the Valley got their licenses.
Our North Hills customers get the 90-Day Done Right Promise in writing on every mold job. If it comes back, Wade comes back. No charge for that. He also takes moisture readings every single day while your home dries and hands you the full log when the work’s done. Most restoration outfits take a reading when they set equipment and another when they pull it. Wade logs every day, because the adjuster wants to see it and you deserve to know your walls are actually drying, not just looking dry.
Our Mold Remediation Services in North Hills
Mold Inspection & Testing
Most North Hills homes we inspect are 1950s-1970s stucco ranches, and the inspection starts where other companies never look: inside the wall cavities near corners and chimney chases. That’s where the 1994 quake cracked the lath and somebody painted over it. Wade probes those spots with a moisture meter before he ever cuts drywall. A full inspection with air sampling and lab results for a standard North Hills ranch runs $350-$600, and if you’ve got a written estimate from another company, bring it in. Wade gives a free second opinion on any written estimate, no strings.
Mold Removal
This is the work of actually cutting out contaminated drywall, sheathing, and insulation, not just spraying something that smells like bleach and calling it done. In North Hills, done wrong means the mold comes back after the next atmospheric river, because the real moisture source was never addressed. Typical mold removal in a single wall cavity or closet runs $800-$2,200. A room with visible mold on multiple walls runs $2,500-$5,000. Wade’s crew sets containment, runs negative air, and removes the damaged material down to clean framing. You get photo documentation of everything before, during, and after, which your adjuster is going to want.
Black Mold Remediation
Black mold in North Hills most often shows up in two places: crawl spaces with flat-grade drainage problems, and wall cavities behind quake-cracked stucco. The health concern is real, especially for older homeowners. We don’t do scare tactics and we don’t do the $12,000 quote for what should be a $3,000 job. Black mold remediation with full containment and air scrubbing in a North Hills crawl space or single room typically runs $2,000-$4,500. If the colony has spread into HVAC ducting, add $800-$1,500 for duct cleaning and treatment. Wade walks you through the scope in writing before any work starts, so you know exactly what you’re paying for.
Air Quality Restoration
After remediation, your home’s air needs to be cleaned, not just the surfaces. That means HEPA air scrubbing, negative air during the job, and post-remediation verification testing. For North Hills homes, we pay close attention to the crawl space, because that’s where most of the air in your house actually comes from. Air quality restoration for a typical 1,200-1,800 square foot North Hills ranch runs $600-$1,800 after remediation is complete. Wade runs the numbers on particle counts before and after, and hands you those logs too.

Common Mold Remediation Problems We See in North Hills Homes
- Quake-cracked stucco hiding wall-cavity mold. The 1994 Northridge quake cracked the lath plane on thousands of North Hills homes. The cracks got skim-coated and painted, and now those sealed voids brew mold colonies invisible from the surface until a leak pushes them into view.
- Pitted galvanized supply lines leaking inside walls. North Hills’s hard water chews through original 1950s-1970s galvanized pipes. The pinhole leaks develop inside wall cavities and feed mold for months before you see a stain. Moisture mapping catches what a visual inspection misses.
- Flat-grade drainage pooling against foundations. North Hills sits on the valley floor with almost no natural slope. When an atmospheric river hits, water pools against foundation walls and seeps into crawl spaces. Mold removal without fixing the grading or adding downspout extensions fails within a season.
- Surface-only treatments that miss the real source. A contractor who only kills visible mold on drywall leaves the cavity colonies behind. The next rain event reactivates them, and you’re paying for the same room twice. Wade won’t take that job unless he can also fix the moisture source.

FAQs - Mold Remediation in North Hills
Because the mold colony isn’t on the surface. In North Hills, the most common cause is a wall cavity behind quake-cracked stucco that was skim-coated after 1994 and never properly sealed. The mold feeds on damp gypsum and insulation inside the cavity, and every atmospheric river reactivates it. The fix requires opening the cavity, removing the contaminated material, and re-sealing the wall with a proper vapor barrier. If someone just wipes the surface and repaints, it comes back. Call (855) 915-0646 and Wade will inspect the cavity itself, not just the wall face.
Yes. A standard home inspection doesn’t open walls, and in North Hills, that’s where the mold lives. Homes built before 1980 that went through the 1994 Northridge quake often have cracked lath planes and delaminated weather barriers behind cosmetic patches. Wade’s inspection includes moisture mapping of wall cavities near corners and chimney chases, plus air sampling if a musty odor is present. It runs $350-$600 and is worth every dollar when you’re deciding whether to walk from the deal or negotiate the price.
North Hills’s hard water pits and pin-holes the original galvanized supply lines in 1950s-1970s homes. Those leaks often happen inside wall cavities or under the floor, feeding mold in the crawl space for months before you see any sign. A proper mold job in North Hills includes checking the supply lines and moisture-mapping the crawl space floor, not just pulling out wet insulation and walking away. If the leak isn’t fixed, the mold comes back.
Because that’s where the 1994 quake cracked the stucco lath, and the crack was skim-coated over without fixing the sheathing underneath. Rain gets in through the micro-fractured stucco, the cavity stays damp, and mold grows inside the wall. We see this constantly on North Hills homes built before 1980. The musty smell after rain is your warning sign. Call (855) 915-0646 and Wade will probe those exact spots with a moisture meter before recommending any work.
No. Paint seals moisture in and gives the colony exactly the warm, dark environment it needs to spread. In North Hills specifically, the stain on the interior drywall usually means there’s a cavity behind it that’s been damp since the Northridge quake created the entry point. Repainting is a $50 fix that guarantees a $3,000 problem six months later. Let Wade open the wall, find the actual moisture source, and fix it so the mold stays gone.
