Why Wendell Water Damage Restoration Is Smithtown’s Preferred Mold Remediation Company
We’re independently owned and operated as part of the Relay Home Co. family, founded in 2006. Smithtown homeowners call us because we put the price in writing before we touch a single tool, text you a live technician arrival time you can track, and send before-and-after photos by text so you can see exactly what was done. No vague four-hour windows. No phone tag. No price that changes at the door.
Our technicians are background-checked and uniformed. They arrive in Smithtown with professional equipment from Dri-Eaz, Phoenix, and XPOWER, running IICRC, RIA, and IFA standard protocols on every job. That matters when someone is cutting into your finished basement walls off Jericho Turnpike or setting containment near a crawlspace by the Nissequogue River. You want a crew that documents moisture readings and drying logs, not one that sprays bleach and waves goodbye.
Blake Sorensen leads our team, and every Smithtown job carries his standard: a written scope before work begins, a 365-Day Done Right Promise in writing, and a free second visit if the repair fails. Dispatched from our New York City office, our crews know Smithtown’s housing stock and the mold patterns specific to Long Island’s North Shore.
Mold Remediation Services in Smithtown
Mold Remediation Services in Smithtown cover everything from contained removal of affected drywall to full structural drying and antimicrobial treatment. A typical Smithtown basement job where mold has spread across drywall and insulation runs $2,200 – $4,800. If it’s isolated to a single wall cavity or a closet, you’re often in the $1,200 – $2,500 range. Every job starts with moisture mapping so we find the source, not just the stain.
Containment and Source Correction
We set negative air containment before disturbing any affected material so airborne spores don’t cross-contaminate your living room or upstairs bedrooms. Then we pull moisture readings across the slab and lower wall cavities to find whether groundwater seepage, crawlspace humidity, or a plumbing leak is feeding the growth. Treating visible mold without correcting the source is a temporary paint job, and Smithtown’s older lower levels rarely give you a second chance to do it right.
Antimicrobial Treatment and Material Removal
After containment and drying, affected drywall and insulation come out and get bagged on-site. We apply an EPA-registered antimicrobial treatment to remaining structural surfaces, then verify dry standard with documented readings before anyone calls the job done. You get a written scope for any long-term corrections, like a French drain or dehumidifier install, so you’re not paying for drywall replacement that just gets moldy again next humid season.

Professional Mold Removal in Smithtown
Professional Mold Removal in Smithtown is not a surface wipe and it’s not a paint-over. It means finding the moisture source, containing the affected area, removing materials that can’t be salvaged, treating the rest, and proving the space hit dry standard before rebuild. Typical Smithtown jobs range from $1,800 for a small contained removal to $6,500+ for full lower-level remediation with structural drying. What moves the needle on cost is the moisture source: active slab seepage costs more to correct than a one-time pipe leak.
Moisture Mapping Before Cutting
We never open a wall blind. We run moisture meters across floors, baseboards, and lower wall cavities to map where water has traveled and where mold is actually growing. In Smithtown’s older split-levels and finished basements, water often wicks up through the slab into drywall that looks completely fine from the outside. Skipping this step is how you end up with a “fixed” basement that smells musty again by August.
Drying Logs and Verification
We track psychrometric drying (monitoring the air’s moisture level so we know when your home is truly dry, not just surface-dry) and log every reading. That documentation is what your insurance adjuster needs if you file a claim, and it’s what proves to you that the job was done to IICRC standard. Replacing drywall before the space is dry means trapping moisture inside the new material. We don’t do that.
Trusted Brands We Service in Smithtown
Our crews in Smithtown work with professional-grade equipment that most homeowners never need to buy themselves. We run Dri-Eaz dehumidifiers and air movers for structural drying, Phoenix fans and LGR units where crawlspaces need aggressive moisture removal, and XPOWER air scrubbers for containment environments. Because we stock these units and their parts locally for Smithtown jobs, we don’t wait on equipment rental stores when your basement is sitting open. That means faster setup on the Landing, in St. James, and every street in between. If you’ve had a previous mold company show up with a couple of box fans from the hardware store, you already know why this matters.
Common Mold Remediation Problems We See in Smithtown Homes
- Slab seepage in finished basements. Many Smithtown homes built before modern vapor barriers have concrete slabs that wick groundwater into lower-level drywall and carpet. The mold keeps returning because no one ever addressed the water coming through the floor.
- High crawlspace humidity off the Nissequogue River corridor. Homes near the river and its tributaries run wetter crawlspaces in summer. Mold grows on floor joists and subflooring even when the living space above feels dry.
- Bleach-and-paint fixes that fail by the next humid stretch. Bleach doesn’t kill mold below the surface of porous materials like drywall and wood. Painting over it seals in spores and moisture, and within two humid weeks the staining is back.
- Missed containment during removal. If a mold crew starts cutting drywall without sealing off the room, airborne spores settle into carpet, furniture, and HVAC returns in the rest of the house. You end up with a bigger problem than you started with.

FAQs About Mold Remediation in Smithtown
Mold keeps coming back because the moisture source was never stopped. In Smithtown specifically, we see this most often in finished basements and slab-on-grade lower levels built before modern vapor barriers, where groundwater wicks up through the concrete slab into drywall and carpet. If you only treat the surface mold without correcting the seepage or crawlspace humidity, the growth returns within one or two humid weeks. Call (940) 466-4354 and we’ll map the moisture before recommending anything.
We schedule most mold inspections in Smithtown within 24 – 48 hours, and we answer the phone live 24/7 so you can get on the schedule immediately. For active water intrusion feeding mold growth, we prioritize same-day or next-morning dispatch. When you call (940) 466-4354, you’ll get a live arrival time you can track, not a four-hour window.
If mold has penetrated porous drywall, you cut it out. Surface treatment doesn’t reach mold roots inside gypsum or paper backing, and leaving it means ongoing spore release into your air. In Smithtown homes with slab seepage, we often need to remove the bottom 2 – 4 feet of drywall where water has wicked up, then treat the framing and install a moisture barrier before any rebuild. We show you moisture readings and photos before we cut anything.
The process is containment, source correction, removal, treatment, and verification. We set negative air pressure in the affected area, pull moisture readings across the slab and walls to find the water source, remove affected materials under containment, apply antimicrobial treatment to remaining surfaces, run drying equipment from Dri-Eaz and Phoenix until the space reaches dry standard, and document everything with drying logs. You get before-and-after photos by text and a written scope for any source correction, like a French drain or dehumidifier.
We tell you what needs replacing and what can be saved, and we back it with moisture readings and documentation. If drywall is dry and surface mold is minimal, we treat it. If it’s saturated or heavily colonized, we cut it. We never push replacement work that isn’t needed, and we put the full scope in writing before anything starts.
