Mold remediation in Highland Park typically costs between $1,800 and $6,500 depending on how far the growth has spread and whether it’s gotten into original plaster, wood lath, or crawlspace framing. Most jobs in the neighborhood take two to five days from containment to final clearance testing. If you’re seeing dark staining on ceilings, smelling something musty in a hallway, or noticing warped baseboards after a winter rain, call us at (213) 349-9500. We answer live, 24/7, and we’ll give you a written price before any work starts.
Highland Park throws specific challenges at mold remediation that a generic crew from across town won’t understand. The homes here were built before modern vapor barriers existed. Original plaster and wood lath wick moisture upward and sideways, so what looks like a small ceiling stain on N. Figueroa often means hidden growth in the attic above. We know these houses because we work in them every week, and we’ve built our drying protocols around preserving the materials that make them worth keeping.
Why Wendell Restoration Los Angeles Is Highland Park’s Preferred Mold Remediation Company
We’ve worked on enough 1900s through 1920s Craftsman bungalows and Spanish Colonial Revival homes in Highland Park to know that mold here rarely stays in one room. A failed composition roof on a hillside lot will send water down through the attic, into the lath, and behind the original wood windows before anyone notices a stain on the bedroom ceiling. What separates our crew is that we treat the whole moisture pathway, not just the visible spot. That’s the difference between a job that holds and one that resurfaces in eight months.
Every technician who shows up at your door in Highland Park is background-checked and in uniform, with a live arrival time you can track on your phone. Before we touch a single tool, you get a written price and a written scope of work. We text before-and-after photos throughout the job, and we finish with a digital invoice you can pay from a link. There’s no vague four-hour window and no price that changes at the door. Highland Park homeowners have told us directly that this is why they call us back and refer us to neighbors on Marmion Way and York Boulevard.
Our Mold Remediation team operates under IICRC, RIA, and IFA standards, using professional-grade equipment from Dri-Eaz, Phoenix, and XPOWER. We’re part of the Relay Home Co. family, founded in 2006, and this location is independently owned and operated to The Relay Visibility Guarantee. Blake Sorensen leads our Los Angeles operation, and he holds every Highland Park job to one standard: you know who’s coming, when they’ll be there, and exactly what it costs. Every repair also carries our 365-Day Done Right Promise in writing. If it’s not done right, we make it right, including a free second visit if the repair fails.
Restoration work we handle
Mold Remediation Services in Highland Park
Mold Remediation Services in Highland Park mean more than spraying bleach on a wall. The job starts with finding where the moisture is coming from, then containing the affected area so spores don’t spread to the rest of your house, then physically removing contaminated material and treating the remaining structure. In a 1923 bungalow, that often means working in tight attic spaces and crawlspaces where original plaster and wood lath have been absorbing moisture for decades. Typical remediation in Highland Park runs $2,200 to $5,800 when we’re dealing with attic framing, lath, and plaster surfaces. Smaller, contained jobs in a single bathroom or closet run $1,400 to $2,600.
Containment and Source Removal
Before we pull out any material, we seal the work area with negative air pressure so spores can’t travel through the plaster walls into adjoining rooms. In Highland Park’s 1920s apartment buildings and duplexes, this matters even more. A mold bloom in one unit will spread through shared wall cavities and vent stacks to neighboring units within days if containment is skipped. We remove drywall, soaked lath, insulation, and carpeting that can’t be salvaged, and we bag it before it leaves the work area.
Structural Drying and Antimicrobial Treatment
Once the contaminated material is out, we dry the remaining structure to IICRC standards using moisture meters and Dri-Eaz dehumidifiers. On original plaster and wood lath, we dry in place with controlled temperature and airflow, because high heat cracks century-old plaster fast. Then we apply antimicrobial treatment to the lath, framing, and plaster surfaces to stop regrowth. The goal is a structure that’s genuinely dry through its depth, not just dry to the touch.

Professional Mold Removal in Highland Park
Professional Mold Removal in Highland Park is the physical extraction part of the job. It’s what happens after we’ve mapped the moisture and sealed the area. We cut out and remove drywall, lath, insulation, and any porous material that’s holding mold, then we HEPA-vacuum and sand the remaining wood framing clean. For a typical attic job in a hillside Craftsman, expect to pay $2,800 to $6,200. A single wall section or closet runs $1,500 to $2,800. The cost depends on square footage affected and whether we’re removing plaster over lath or just modern drywall.
Attic Mold Removal in Hillside Homes
Attics in Highland Park’s hillside Craftsman homes are usually tight, hot, and packed with original framing and knob-and-tube wiring. We remove the mold-contaminated insulation and lath carefully, without disturbing the old electrical. If we find moisture-damaged wiring, we flag it for an electrician before we close anything up. No one should be pulling wet insulation past live knob-and-tube circuits without knowing exactly where those lines run.
Crawlspace and Raised Foundation Treatment
Most Highland Park bungalows sit on raised foundations with dirt or concrete crawlspaces that trap humidity after winter rains. We remove mold from the floor joists and sill plates, treat the wood, and set up drying equipment in the crawlspace itself. If the sill plate has rotted, we’ll tell you on the spot and include the repair in your written scope. Silencing that moisture source matters as much as the removal itself.
Trusted Brands We Service in Highland Park
We run Dri-Eaz dehumidifiers, Phoenix air movers, and XPOWER air scrubbers on Highland Park jobs because these are the same commercial-grade machines used on large loss sites. They move more air, pull more water, and hold consistent temperatures better than rental units from a hardware store. For our Highland Park customers, that means faster drying in tight attic spaces and less time with machines running inside your home. We keep equipment and replacement parts staged in our Los Angeles office, so we’re not waiting on a shipment when your ceilings are open.

AfterCommon Mold Remediation Problems We See in Highland Park Homes
- Drying original plaster too fast. Highland Park’s 1900s and 1920s homes have plaster walls and wood lath that crack and delaminate when hit with high heat. We dry them slowly, with controlled airflow, so the material stays intact and we’re not repairing damage we caused ourselves.
- Skipping containment in tight, alley-loaded homes. A mold remediation in a duplex on a narrow lot can spread spores to the unit next door through shared walls and attic space. We run negative air containment on every job, not just the big ones, because the cost of one careless spread is a neighbor’s whole remediation.
- Missing hidden moisture behind original wood windows. After winter flash floods, water seeps behind window casings and into the wall cavity. Mold grows there for months before anyone sees it. We open a small inspection point and check with moisture meters before declaring a wall dry.
- Rushing a roof leak repair without checking the attic below. A new roof is not a mold fix. We frequently find mold in the attic framing and insulation long after a Highland Park homeowner replaced a composition roof. Always inspect the structural cavity after a leak, not just the surface.

FAQs About Mold Remediation in Highland Park
Older homes add one to two days to a typical remediation because we dry original plaster and wood lath slowly to avoid cracking, and we often have to work in tighter attic and crawlspace access than newer builds. A standard attic job that takes three days in a modern home often takes four to five in a 1920s Craftsman. The methods change more than the timeline: we use lower heat, more controlled airflow, and more frequent moisture readings than you’d need in a drywall-and-framing house built after 1980.
Yes, and honestly, if a contractor tells you they can skip containment on a shared-wall building, that’s a red flag. In 1920s Highland Park duplexes and apartment buildings, wall cavities and attic spaces are often continuous across units. A mold bloom in one unit will spread to the neighbors through those shared cavities. We set up negative air pressure containment on every job in a multi-unit building, period. Call (213) 349-9500 and we’ll assess your specific building.
In Highland Park, the most common trigger is a failed composition roof after heavy winter rain. Water pools at the low points over hillside lots, finds a seam or crack, and seeps into the attic for days before anyone notices a ceiling stain below. The second most common source is failed window flashing around original wood windows, which lets water run behind the casing into the wall. Both situations create hidden moisture that feeds mold inside the structure, which is why a visible stain is usually the last symptom, not the first.
Yes, and we plan for it before we cut anything. The goal on a Spanish Colonial Revival is to remove only what’s contaminated, preserve the original plaster and lath where possible, and match any replacement materials by period, texture, and finish. We’ve sourced specific plaster aggregates and wood lath profiles for Highland Park restorations, and we’ll document the original condition before removal so the repair matches. If we’re removing a section of original plaster, we’ll show you the plan in writing before work starts.
We work around existing knob-and-tube wiring carefully, and we never pull insulation or lath past live circuits without flagging the wiring for an electrician first. If we find moisture-damaged wiring in the mold-affected area, we’ll stop that section and coordinate with a licensed electrician before we proceed. Nobody should be doing remediation work over compromised original wiring. Call us at (213) 349-9500 and we’ll walk you through what we see.
