Mold remediation in Montclair typically runs $1,800 – $6,500 depending on how far the growth has spread, and most jobs we handle in the 91763 ZIP are completed within three to five working days. That’s the honest range, not a teaser number. If you’ve found mold in a hallway, attic, or crawl space, call us at (877) 358-7678. We respond to Montclair calls the same day with a moisture mapping assessment, and we’ll give you a written scope of work before any equipment gets unloaded.
Montclair is a city we know block by block. The housing stock here, mostly single-story stucco tract homes from the 1950s through the 1980s, gives us a predictable set of mold problems that newer construction elsewhere in the Inland Empire simply doesn’t have. Original galvanized plumbing. Cast-iron drains. Composite shingle roofs at or past end-of-life. When those systems fail, they fail inside walls and attics where moisture sits for months before anyone sees it. That’s where our Mold Remediation team comes in.
Why San Bernardino Restoration Co Is Montclair’s Preferred Mold Remediation Company
We’ve worked enough homes in Montclair to know where mold hides here. Not in the obvious places, though we find it there too. It’s the north-side streets closest to the foothills, where Santa Ana winds peel back ridge caps and shingles. It’s the original 1960s galvanized supply lines that develop pinhole leaks behind hallway baseboards. It’s the cast-iron drain stacks that crack at the hub joint and weep sewage-tainted moisture into wall cavities for years. Local knowledge like that isn’t something you get from a company that serves six counties and parachutes in for a day.
Technicians on our Montclair jobs are IICRC-certified, which means they’ve been tested on the actual science of mold remediation, not just trained by watching a video. We document every moisture reading, every drying log entry, and every clearance test. That documentation matters when you’re filing an insurance claim. Adjusters expect it, and frankly, so should you. If a company can’t produce a moisture map and a written scope before starting, they’re guessing. We don’t guess.
Our team is led by Noel Armenta, who has built San Bernardino Restoration Co around a simple standard: commercial-grade equipment and documented protocol on every job, from a single bathroom wall to a full attic remediation. No consumer-grade rentals. No shortcuts on containment. No “spray and walk away” treatments.
Restoration work we handle






Black Mold Removal in Montclair
Black Mold Removal in Montclair usually falls between $2,200 and $5,800, with the higher end reflecting growth that has moved into attic insulation, framing, or multiple rooms. The term “black mold” gets thrown around loosely, but the work is specific: containment, negative air pressure, removal of porous materials that can’t be salvaged, antimicrobial treatment on framing and hard surfaces, and a documented clearance test at the end. In Montclair homes, black mold is most common in attics after wind-driven rain, behind walls with leaking galvanized supply lines, and in bathrooms with exhaust fans that were never properly vented.
Containment and Negative Air
Before we touch any mold, we seal the affected area with 6-mil poly and establish negative air pressure using HEPA-filtered fans. This prevents spores from moving into the rest of the house. On a 1960s Montclair tract home, that can mean containing an entire attic or just a single closet. We size the containment to the job, not to a template.
Clearance Testing
After remediation and structural drying, we run an air quality clearance test to confirm spore counts have returned to acceptable levels. You get that result in writing. Not a verbal “looks good,” but an actual printed or emailed report. That’s the difference between remediation and a surface wipe-down.
Mold Removal Contractor in Montclair
A Mold Removal Contractor in Montclair should be quoting $1,800 – $4,500 for a standard wall or ceiling remediation, and more when the work extends into the attic or crawl space. What you’re paying for is not just labor. It’s the equipment, the containment materials, the disposal fees for contaminated debris, and above all, the documented process that keeps the mold from coming back. We see too many Montclair homeowners who paid a handyman to scrub a wall with bleach, only to have the mold return within six weeks because the moisture source was never addressed. That’s not removal. That’s a delay.
Moisture Mapping Before Removal
Every mold removal job we do in Montclair starts with moisture mapping. We use penetrating and non-penetrating meters to find where the water is coming from. In these older tract homes, the source is often a pinhole leak in a galvanized supply line inside the wall cavity, something a visual inspection would never catch. If the source isn’t found and fixed, you’re paying for mold removal twice.
From Extraction to Clearance
Our team handles the entire job, from initial water extraction if there’s active moisture, through drying with Dri-Eaz dehumidifiers and XPOWER air movers, to antimicrobial treatment and final clearance. No coordinating with three different contractors. One team, one scope of work, one documented result.
Trusted Brands We Service in Montclair
Montclair homeowners regularly ask us which equipment brands they should look for in a restoration contractor. We run Dri-Eaz dehumidifiers, Phoenix axial fans, and XPOWER air movers, the same machines used on large commercial losses, not consumer-grade rentals you’d pick up at a hardware store. For Montclair’s older homes, we also use Injectidry wall-cavity drying systems when moisture is trapped inside wall framing. This lets us dry wall cavities without tearing out every square foot of drywall, which protects your structure and keeps the job scope realistic. When a piece of that equipment needs a part or a filter, we stock what we need locally. No waiting on a shipment while your attic stays wet.

AfterCommon Mold Remediation Problems We See in Montclair Homes
- Wind-driven rain infiltration on the north side. After a Santa Ana event, we find ridge caps and shingles scattered into neighboring yards along the streets closest to the foothills. Water gets pushed under the remaining shingles and soaks attic insulation and sheathing. Mold follows within 48 to 72 hours.
- Original galvanized supply lines with pinhole leaks. Montclair homes built in the 1950s through the 1970s often still have their original galvanized pipes. These develop pinhole leaks inside wall cavities, where moisture accumulates behind drywall and feeds mold for months before any visible sign appears.
- Cast-iron drain backups. A cast-iron drain stack in a 1960s Montclair home can crack at the hub joint, leaking Category 2 or 3 water into wall and floor cavities. This requires containment and antimicrobial treatment, not just drying. Cross-contamination is a real risk if this is handled wrong.
- Attic mold from exhaust fans venting into the attic, not outside. Older Montclair homes often have bathroom exhaust fans that terminate in the attic rather than through the roof. Every shower pushes humid air into the attic. Over a decade, that’s persistent moisture on the sheathing and a predictable mold bloom.

FAQs About Mold Remediation in Montclair
Mold can begin growing in attic insulation and on sheathing within 48 to 72 hours of water intrusion, especially in hot weather when attic temperatures rise quickly. The first thing to do is tarp the exposed area or call a roofing contractor for temporary protection. Then call us at (877) 358-7678 to assess the moisture load. The faster we get drying equipment running, the less likely you’ll need a full attic mold remediation.
A musty smell in a hallway of a 1950s – 1970s Montclair home often points to a pinhole leak in a galvanized supply line inside the wall cavity. The leak may be small enough that you never see water, but the cavity stays humid, and mold grows on the paper facing of the drywall and on the framing. By the time you smell it, it’s usually been growing for weeks or months. Moisture mapping will pinpoint the source, and we’ll quote the remediation based on what the meters show.
Yes. Water from a cast-iron drain backup is classified as Category 2 or 3, meaning it’s contaminated. Remediation requires full containment, negative air pressure, and antimicrobial treatment on any affected framing and building materials. You cannot simply dry this out and spray a fungicide. The protocol is different from Category 1 clean water damage, and doing it wrong cross-contaminates the rest of the house. Call (877) 358-7678 and we’ll walk you through what applies to your specific situation.
Prevention starts with removing the moisture source. After drying the attic with Dri-Eaz dehumidifiers and air movers, we treat affected framing with an antimicrobial, then confirm the roof is sealed or repaired so water can’t re-enter. We also document moisture readings at the end of the job so you have proof the attic was dry. On Montclair homes with chronic wind exposure, we often recommend a follow-up roof inspection before the next Santa Ana season. The mold won’t come back if the water stops coming in.
We run Dri-Eaz dehumidifiers, Phoenix and XPOWER air movers, and Injectidry wall-cavity drying systems on Montclair mold jobs. These are professional-tier machines, the same ones used on large commercial losses. We don’t bring consumer-grade rentals into your home. The equipment matters because proper drying is what prevents mold from rebounding after remediation. If the framing isn’t actually dry, mold comes back. That’s why we document every reading until the structure is dry.
