Our story
How We Started in San Luis Obispo
San Luis Mold Pros started in 2020 after a wet winter pushed water through crawlspaces and wall cavities all over San Luis Obispo. We were a two-truck crew then, working out of a shop off Broad Street, and most of our first calls were repeat referrals from property managers who could not get anyone to show up. Six years later we still run the same playbook: find the moisture source first, contain the work area, and dry the structure before anyone talks about repairs. That order matters, and it is why our About Mold Remediation Company San Luis Obispo CA page reads less like marketing and more like a job log.
Since then we have built a licensed and insured crew that handles residential mold cleanup professionals San Luis Obispo CA work and commercial loss at the same time, from single-family homes near Cal Poly to retail spaces downtown. We added a dedicated estimator, a full-time project manager, and a drying division that runs Dri-Eaz and Phoenix Restoration Equipment. If you want to learn about a local mold remediation company in San Luis Obispo, start with the fact that we still answer the phone ourselves and we still walk every job before we quote it.
Practical standards, local accountability.
San Luis Mold ProsWhat guides the work
What We Stand For
Our mission is simple: dry the building, remove the contamination, and prove it with numbers before we pack up. Every San Luis Obispo mold remediation team member carries a moisture meter, a hygrometer, and a Protimeter on their belt, and we log readings at intake, during drying, and at clearance. We follow the ANSI/IICRC S520 Standard for Professional Mold Remediation because it gives you and your insurance adjuster a shared language for what done means. The outcome we want is a home or business you can occupy without moldy odors, and a documented reason to believe the problem will not come back.
Our values
How We Work
These are the four rules our technicians work under on every San Luis Obispo County job, whether it is a 200-square-foot bathroom or a 20,000-square-foot commercial loss. They are not slogans. They are what you will see us do.
Find the Water First
Mold does not grow without moisture, so we chase the source before we touch the growth. That means an infrared thermal camera on the walls, a moisture meter on the framing, and a hygrometer reading in every affected room. On a typical San Luis Obispo job we find water intrusion from a failed supply line, a clogged condensate drain, or roof flashing that has been leaking since last winter. Fix the source, or the mold comes back in 30 days.
Contain and Filter
We build polyethylene containment sheeting around the work zone and run a negative air machine with HEPA filter cartridges so spores do not migrate into your kitchen or your kid's bedroom. Our techs wear P100 respirator filters, and we HEPA vacuum every surface before any antimicrobial cleaner goes on. On a recent Islay Street job, post-remediation air sampling pump results came back clean on the first pass because the containment held.
Dry to a Number
Wet building materials do not dry on their own schedule. We set LGR dehumidifiers and XPOWER air movers, then check readings daily against the dry standard for the material. A saturated wall cavity in San Luis Obispo often takes three to five days to hit target, longer in January when outdoor humidity sits above 70 percent. We do not pull equipment until the numbers say the structure is dry, not when the calendar says so.
Show the Proof
You get photos of the containment, daily moisture logs, and clearance results in writing. If your insurance carrier needs documentation for a claim, we hand over the same file we keep. That paper trail is also how we spot mold recurrence after incomplete drying, which is the single most common problem we get called to fix on homes where a previous contractor pulled gear too early. Ask us for the file on any trusted mold abatement company San Luis Obispo job and see what you get.
The people behind the work
Who Shows Up at Your Door
Our field team runs six to ten technicians depending on the season, and every lead carries an IICRC Applied Microbial Remediation Technician credential plus IICRC Water Damage Restoration Technician and Applied Structural Drying training. Two of our project managers hold the ACAC Council-certified Microbial Remediator designation. We hire locally, so most of our crew lives within fifteen minutes of the 93405 ZIP and knows exactly what a San Luis Obispo marine-layer winter does to a poorly vented attic. We also keep current on OSHA respiratory protection requirements and the EPA Renovation, Repair and Painting Rule, which matters on pre-1978 housing stock around the city. When you call (805) 507-9326, you talk to someone who has actually been inside a containment, not a call center. That is how a California mold remediation specialists San Luis Obispo crew should operate.

Residential Mold Remediation
We remove mold from attics, bathrooms, kitchens, and crawlspaces in San Luis Obispo homes. Expect polyethylene containment sheeting, negative air machines, and HEPA vacuums before any demolition. We also check insulation and vapor barriers because hidden mold growth often starts behind them.
View service 02Commercial Mold Remediation
Offices, restaurants, and rental properties in Downtown San Luis Obispo and the Railroad District need fast turnaround. We schedule after-hours work, use LGR dehumidifiers to protect inventory, and provide documentation for property managers and insurance claims. Air sampling pump results are included at clearance.
View service 03Black Mold Removal
Black mold contamination usually means Stachybotrys behind drywall or under flooring. We isolate the area with negative-pressure ducting, remove porous materials, and apply antimicrobial cleaner to framing. P100 respirator filters and full containment keep spores out of the rest of your San Luis Obispo home.

What San Luis Obispo Customers Say
We had a leak behind the shower for who knows how long. They cut out the drywall, ran scrubbers for four days, and the musty smell is gone. The clearance test came back clean and they showed me the numbers. Worth every penny.
I manage six rentals near Downtown San Luis Obispo and needed documentation for a tenant dispute. They photographed everything, tested the air, and gave me a report my attorney could actually use. Fast turnaround too.
Black mold in the garage after last winter's rain. They explained why it happened, not just how to clean it. Installed a vapor barrier and fixed the grading so water runs away from the wall. No mold this year.
Called on a Friday about mold under the kitchen sink. They came out same day, gave me a written estimate, and started Monday. The crew was careful with my floors and cleaned up better than they found it.
Our restaurant had a roof leak that soaked insulation above the dining room. They worked after hours so we did not lose a single day of business. Air sampling results were included and passed on the first try.

Most San Luis Obispo mold remediation jobs run $1,800 to $4,500 for a standard project, and $5,500 to $12,000 when drywall, insulation, and flooring have to be removed and rebuilt. Inspection and testing alone is $250 to $450. Square footage, mold type, and how much material is contaminated drive the final number.
Yes. San Luis Obispo sits close enough to the coast that fog and marine air push indoor humidity above 60 percent for weeks at a time, especially in spring and fall. At that level, condensation forms on cool walls and windows, and mold can start on drywall, baseboards, and closet corners without any leak at all. A dehumidifier and better ventilation usually solve it.
A single-room job typically takes two to four days, and whole-house remediation runs five to ten days. The removal phase is often one or two days; the rest is structural drying with LGR dehumidifiers and air movers until a moisture meter shows the framing is dry. Clearance air sampling adds another two to three days for lab results.
In California, landlords must maintain rental units in a habitable condition, and that includes fixing moisture problems that cause mold. Tenants should report leaks and visible growth in writing. We document conditions with photos, moisture readings, and lab results so both sides have a clear record for San Luis Obispo County disputes.
Mold removal means taking the visible growth off a surface. Mold remediation is the whole process: finding the moisture source, containing the area with negative air, removing contaminated materials, drying the structure, and verifying with air sampling that spore counts are back to normal. Removal alone often fails because the moisture that caused the mold is still there.
