Mold remediation in Jericho typically costs $1,800 – $6,500 depending on square footage, containment needs, and where the colony is hiding. Most Jericho jobs we handle are finish-sensitive: a finished basement behind a wet bar, a wine cellar, a custom entertainment wall. We contain, dry, treat, and restore without tearing out more than necessary. If you’re seeing dark spots on drywall, catching a musty smell near your HVAC returns, or found water after a nor’easter, call (516) 559-6972. We answer live, send a background-checked technician with a live arrival time, and put your written price in front of you before any tool comes off the truck.
Why Wendell Restoration Hempstead Is Jericho’s Preferred Mold Remediation Company
Jericho homeowners tend to ask harder questions than most. They want to know if the wainscoting survives, whether the white oak treads can be saved, how you’ll keep mold spores out of the HVAC while you work. Those are the right questions, and we answer them with a written scope before work starts. Our crews work Jericho week in and week out, and we know the houses: quarter-acre to half-acre lots, full finished basements, custom built-ins, sump pumps in the mechanical room, perimeter drains that back up during coastal storms. That local familiarity changes how fast we move and how precisely we stage containment. Wendell Water Damage Restoration is part of the Relay Home Co. family, founded in 2006, and every Jericho job runs under the same standing offers: a written price before we start, a written 365-Day Done Right Promise on every repair, and a free second visit if it fails. Blake Sorensen leads our team, and he holds every job in Jericho to those terms.
Restoration work we handle






Mold Remediation Services in Jericho
Mold Remediation Services in Jericho start with containment and moisture mapping, not demolition. We build negative-air containment around the affected area, map moisture behind drywall and custom millwork with professional meters, then remove contaminated material under IICRC, RIA, and IFA standards. The goal is to dry the structure to its original moisture level – not just surface dry – and leave the custom finishes you paid for intact. Most Jericho mold remediation projects run $2,200 – $5,800 for a contained basement or crawl space job. A straightforward bathroom ceiling from a plumbing leak might land around $1,800 – $2,600. The bigger the finished area, the more containment chambers and air scrubbers, and the more custom trim to protect, the higher the number.
Containment Before Anything Else
Mold spreads through airborne spores. Open a moldy wall in a Jericho colonial and run a fan, and you’ve just sent spores into the HVAC return, behind the crown molding, and up through the stairwell. We build a sealed containment zone with negative air pressure before we ever cut drywall. That’s the difference between removing mold in one room and chasing it through the whole house two weeks later.

Moisture Mapping and Finish Preservation
Behind the wainscoting, under the marble threshold, inside the knee wall under the stairs – that’s where moisture hides. We don’t guess. We map. Every reading tells us whether material can be dried and saved or must come out. Your custom millwork isn’t assumed disposable. We pull readings from the wood, the drywall behind it, and the slab underneath, then show you the numbers before we recommend cutting.

Professional Mold Removal in Jericho
Professional Mold Removal in Jericho is not a bleach-and-paint job. It’s source removal, antimicrobial treatment, and structural drying, done to a written protocol. The price depends on what we find once containment is up: a contained vanity leak might run $1,900 – $3,200, while a full finished basement with mold behind a wet bar, home theater wall, and under luxury vinyl plank can run $4,800 – $6,500. On a cul-de-sac off Hazelwood Drive, our crew contained a finished basement where a failed sump pump during a March nor’easter had left category 2 water in the carpeted home theater and custom built-in wet bar. After water extraction, we set up air movers and dehumidifiers, taking moisture readings from the oak treads and drywall behind the wainscoting. The millwork was saved, but the saturated carpet pad and lower drywall had to be removed before antimicrobial treatment and structural drying brought the space to pre-loss condition.
Source Removal, Not Surface Treatment
You can’t kill mold on drywall with a spray. The colony lives inside the material. In Jericho basements, that means cutting out the affected drywall, bagging it inside containment, and treating the framing behind it. Anything less and you’re painting over a living problem that comes back with the next humid July.
Black Mold in Jericho Finished Basements
Stachybotrys – the one people call black mold – loves wet cellulose. Drywall, carpet pad, the paper backing on insulation. In a finished Jericho basement with high-end finishes, black mold usually starts behind something: a built-in entertainment center, a wet bar, a wine closet. By the time you see it, it’s been growing for weeks. We find the source, contain it, remove it, and verify the air with post-remediation testing.
Trusted Brands We Service in Jericho
Most Jericho homes have high-end finishes and standard drywall, which means the equipment matters as much as the hands using it. We run Dri-Eaz dehumidifiers and air movers, Phoenix moisture meters and injection systems, and XPOWER air scrubbers for negative-air containment. These are the same professional-grade machines used on commercial loss sites, not rental-store equipment. For Jericho homeowners, that means faster structural drying, fewer days of equipment in your finished basement, and moisture readings we can show you in real time. We stock replacement filters, containment barriers, and drying components locally for fast turnaround when your project needs an equipment swap mid-job. Run-of-the-mill disposable gear isn’t what we’d put in a Jericho home theater. We don’t.

AfterCommon Mold Remediation Problems We See in Jericho Homes
- Skipped containment turns a small patch into a whole-house problem. A three-foot mold patch behind a built-in entertainment center in Jericho can spread spores through the HVAC returns in hours. Without negative-air containment, every room connected to that duct run becomes a potential new colony.
- Dehumidification without moisture mapping misses hidden pockets. We’ve re-treated Jericho basements where another company ran a dehumidifier for a week and called it done. The mold was behind the custom millwork and under the marble threshold, invisible and thriving. We map every wall, every threshold, every stair stringer.
- Treating sump pump overflow as category 1 water leaves black-water pathogens behind. Jericho sump pumps fail during nor’easters, and the water that backs up isn’t clean. It’s category 3. If it isn’t treated as such, the pathogens stay in the slab and under the luxury vinyl plank. The odor comes back. The mold comes back. And now you’re paying for remediation twice.
- Hot, humid Long Island summers push sealed-up Jericho homes over 60% relative humidity. Tightly sealed luxury homes hold moisture. July and August in Jericho can push indoor humidity levels high enough to feed mold growth inside walls even without a leak. A crawl space treatment or a humidity control plan is often the difference between one remediation and a recurring one.
Pricing for Mold Remediation in Jericho, NY
Here are real numbers for Jericho, not national averages. A contained single-room mold removal – a bathroom ceiling, a laundry closet, a crawl space section – runs $1,800 – $3,200.

Full air quality restoration after a whole-home spore spread, with post-remediation verification, lands between $3,500 – $5,800. What moves the number: how much finished surface we’re protecting, how many containment chambers, whether category 3 water is involved, and whether we’re saving or rebuilding custom millwork.

FAQs About Mold Remediation in Jericho
Mold can begin growing on wet drywall within 24 – 48 hours of a flood, and Jericho’s humid summers accelerate that timeline. The dryer you can get the space in the first day, the less remediation you’ll need. Call (516) 559-6972 the moment water is out – our crews can be in Jericho with extraction and drying equipment same day, and the sooner we contain and dry, the more of your finishes we can save.
It shouldn’t. In Jericho homes, preserving custom millwork, oak treads, and imported finishes is part of the job, not an afterthought. We take moisture readings from the wood itself, set up containment to protect unaffected areas, and only recommend removal when the material cannot be dried to a stable moisture level. We’ve saved wainscoting, wet bars, and hardwood floors in Jericho basements. When material has to come out, you’ll know exactly why and see the numbers before we cut.
Not necessarily everything. Sump pump overflow is category 3 water because it carries ground contaminants. That means saturated carpet pad, drywall behind the water line, and any porous materials in contact with the water typically get removed. But the framing, the slab, and the surrounding finished materials can usually be saved with proper antimicrobial treatment and structural drying. We walk you through exactly what comes out and what stays before any work begins.
A dehumidifier lowers air humidity, but it won’t reach mold inside walls, behind millwork, or under flooring. In Jericho’s tightly sealed homes, moisture gets trapped in structural cavities where air doesn’t circulate. If you’re seeing recurring mold, there’s usually a hidden moisture source – a slow plumbing leak, a perimeter drain issue, or condensation against the foundation. We find and fix that source, then treat the mold. Otherwise it’s just a cleanup, not a cure.
We work in controlled sections. Containment goes around the affected area only, with an air scrubber maintaining negative pressure so spores can’t migrate to your theater seating or wine racks. We access the mold from the least visible side when possible – often through a utility closet or an adjacent unfinished space. Custom trim is removed carefully for reinstallation, and we treat the framing behind the wall without opening more than necessary. The goal is always the same: remove the mold, not your room.
If you’ve found mold in your Jericho home – or you suspect it but can’t see it yet – call (516) 559-6972. A live person answers. You’ll get a written price before any work starts, a live arrival time you can track, and before-and-after photos texted to your phone. That’s the way it should work.
