Why Wendell Restoration Los Angeles Is North Hollywood’s Preferred Mold Remediation Company
North Hollywood homeowners call us because we treat their house like the specific 70-year-old structure it is, not a generic box. Our crews know that a 1952 bungalow off Magnolia Boulevard has different moisture problems than a 1980s apartment near the B Line station. That matters when you’re deciding whether mold behind a baseboard is a $900 surface job or a $4,000 wall-cavity remediation. We’ve been doing this work since 2006 as part of the Relay Home Co. family, and every job is independently owned and operated to The Relay Visibility Guarantee: you get a live arrival time you can track, a written price on the spot, and before-and-after photos texted to your phone.
The 365-Day Done Right Promise backs every remediation we complete in North Hollywood. If it’s not done right, we make it right, stated in writing on every job. If the repair fails, you get a free second visit. No vague assurances. No callback queue. Our technicians are background-checked, uniformed, and IICRC-, RIA-, and IFA-standard trained. They show up with professional equipment from Dri-Eaz, Phoenix, XPOWER, B-Air, and Injectidry, the same brands used on large commercial loss sites.
Blake Sorensen, who leads our team, has a simple rule: the number on the written estimate is the number you pay. That’s why North Hollywood customers stick with us for Mold Remediation work year after year.
Restoration work we handle
Mold Removal Service in North Hollywood
Mold Removal Service in North Hollywood usually runs $1,200 to $3,800 for visible surface contamination in a single room, though the final number depends on how deep the growth goes. In older North Hollywood homes, what looks like a 10-square-foot patch on a bathroom ceiling often extends into the wall cavity behind it. We cut away and bag contaminated drywall, sand and treat exposed framing, and rebuild with clean materials, always following containment protocol so spores don’t spread through your house during the job.
Containment and Spore Control
Before any cutting starts, we seal the work area with negative air pressure and plastic containment. You’d be surprised how many North Hollywood homeowners tell us a previous company just scrubbed the wall and painted over it. That’s not removal. That’s a temporary cover-up that lets mold keep feeding inside the wall cavity.
Surface vs. Cavity Remediation
Surface mold on painted drywall can sometimes be remediated for under $1,500. But if moisture has wicked into the wall assembly, which we see constantly in North Hollywood’s double-drywall bungalows, expect $2,500 to $5,000 for proper cavity treatment. We’ll show you photos of exactly what we found before we touch anything.
Mold Remediation Services in North Hollywood
Mold Remediation Services in North Hollywood cover the full scope: identifying the moisture source, containing the contamination, removing affected materials, drying the structure, and applying antimicrobial treatment. Most full-home remediations in this area land between $3,500 and $6,500. The older the house, the more likely the scope expands once we open the walls. That’s why our written estimate includes a line-by-line breakdown, and if we find something unexpected, you approve the change before we proceed.
Moisture Mapping and Source Elimination
Mold always has a water source. In North Hollywood, that source is frequently a corroded cast-iron drain line under a slab foundation, or a failed water heater in a closet. We use moisture meters and thermal imaging to trace the water path, not just the visible mold. If we don’t stop the moisture, the mold comes back. It’s that simple.
Drying and Antimicrobial Treatment
After removal, we deploy professional drying equipment, Injectidry panels for wall cavities, XPOWER air movers, Phoenix dehumidifiers, to pull moisture from structural materials. Then we apply antimicrobial treatment to prevent regrowth. The whole process follows psychrometric drying, which tracks the air’s moisture level so we know when your home is truly dry, not just surface-dry.

Trusted Brands We Service in North Hollywood

AfterCommon Mold Remediation Problems We See in North Hollywood Homes
- Double-drywall assemblies in 1940s-1950s bungalows. Many North Hollywood homes were renovated with a second layer of drywall screwed over the original plaster. Water gets trapped between the two layers and mold thrives in that dark, humid gap. A quick surface wipe never touches it.
- Settled slab foundations channeling El Niño rainwater. Clay soil under North Hollywood expands and contracts through the wet-dry seasons, cracking older slabs. Sudden winter downpours push water through those cracks and into wall plates, causing recurring mold behind baseboards.
- Converted Arts District lofts with exposed brick and timber. These buildings weren’t designed for modern ventilation. A single roof leak in one of these converted warehouses can drive moisture behind brick and old timber, creating hidden mold that only shows up as a musty smell months later.
- Failed cast-iron plumbing in original construction. Homes built in the 1940s and 1950s still have original cast-iron drain lines. When they fail, they leak Category 3 water, sewage-contaminated, into the slab and walls. Mold follows within 48 hours.

FAQs About Mold Remediation in North Hollywood
Because the moisture source hasn’t been eliminated, and the mold is living inside the wall cavity, not on the surface. In 1950s North Hollywood bungalows, we typically find moisture trapped between original plaster and a second layer of drywall added during a past renovation. Cleaning the outer surface kills the visible mold but leaves the hidden colony untouched. The fix is cavity remediation: remove the outer layer, treat the framing and the backside of the plaster, dry the wall assembly, and address the original water source, usually a corroded cast-iron drain line or slab seepage. Call (213) 349-9500 and we’ll map the moisture before recommending anything.
Mold can begin growing within 24 to 48 hours of a cast-iron pipe leak, especially in North Hollywood’s warm summer months. The water saturates the slab and wicks up into wall plates and drywall. By day three, spore activity is usually established. If you’ve had a slow leak behind a wall for weeks, which is common with corroded cast-iron, the mold is already extensive before you ever see a stain. That’s why we respond fast and why our estimate is free. Call (213) 349-9500.
Category 3 water is heavily contaminated, think sewage or floodwater carrying bacteria and pathogens. In an Arts District loft with exposed brick and timber, that water soaks into porous surfaces and creates a serious health and structural risk. Remediation requires full containment, removal of all saturated material including portions of timber if they hold contamination, aggressive antimicrobial treatment, and verification drying. This is not a cleaning job. It’s a controlled removal and rebuild. We handle it with the same protocol we use on commercial loss sites, and you get the 365-Day Done Right Promise in writing.
El Niño downpours hit North Hollywood’s clay soil hard. The soil expands, then contracts during the dry months. Over decades, that movement cracks foundations and shifts the slab. In low-rise garden apartments built in the 1970s, water from a heavy storm pushes through those cracks and seeps into wall plates, then wicks up into drywall. The result is mold behind baseboards and inside lower wall cavities that returns every rainy season until the water entry is addressed. We trace the water path and fix the entry point, not just the mold.
In many cases, yes. We use Injectidry panels on wall cavities and Phoenix dehumidifiers with psychrometric drying, tracking the air’s moisture level so we know when your home is truly dry, not just surface-dry, to extract moisture from behind original plaster without removing it. The plaster’s condition matters: if it’s crumbling or saturated with contaminated water, it may need to go. We’ll show you moisture readings and photos before recommending any demolition. You approve the scope in writing before we start.
