Mold
Remediation
Mold can start growing within 24–48 hours of water exposure. Doan Restoration's IICRC-certified team identifies, contains, and removes mold safely — then treats the source to ensure it doesn't come back.
Why Mold Is a Serious Health & Property Concern
Mold isn't just unsightly — it's a health hazard. Mold releases microscopic spores and mycotoxins into the air that cause respiratory problems, allergic reactions, headaches, and fatigue. For people with asthma or compromised immune systems, mold exposure can trigger severe health episodes.
In Columbus, Ohio's humid summers and wet springs create ideal conditions for mold growth — especially in basements, crawl spaces, bathrooms, and any area that has experienced water damage. Mold often grows hidden behind walls, under flooring, and inside HVAC systems where it's invisible but actively contaminating your indoor air.
DIY mold removal is risky and often ineffective. Disturbing mold without proper containment sends millions of spores airborne, spreading contamination throughout your home. Doan Restoration follows strict IICRC S520 standards for safe, thorough mold remediation — protecting your family and your property.
Our Mold Remediation Process
We follow IICRC S520 standards — the industry benchmark for professional mold remediation.
Inspection & Air Testing
We inspect your property thoroughly and collect air and surface samples sent to an independent lab. Lab results identify the mold species and spore concentration — giving us a clear remediation plan.
Containment
We seal off affected areas with polyethylene sheeting and establish negative air pressure to prevent spores from spreading to clean areas during removal. HEPA air scrubbers run continuously.
Mold Removal
Contaminated materials are carefully removed — drywall, insulation, carpet, and other porous materials that harbor mold. Non-porous surfaces are scrubbed with antimicrobial solutions and HEPA vacuumed.
Antimicrobial Treatment
All affected areas are treated with EPA-registered antimicrobial agents that kill remaining mold and inhibit future growth. We treat structural framing, subfloors, and any surfaces that will remain in place.
Post-Remediation Testing
After remediation is complete, we conduct clearance testing — new air and surface samples verified by an independent lab — to confirm mold levels are back to normal before rebuild begins.
Source Correction & Rebuild
We address the moisture source that caused the mold — fixing leaks, improving ventilation, or upgrading drainage. Then we rebuild with new materials, restoring your property to pre-loss condition.
Signs You May Have a Mold Problem
Musty or Earthy Odor
A persistent musty smell — especially in basements, bathrooms, or near exterior walls — often indicates hidden mold growth. The smell may come and go with humidity levels.
Visible Discoloration
Black, green, white, or gray spots on walls, ceilings, or around windows. Mold can also appear as a fuzzy growth on surfaces or dark staining on grout and caulk.
Water Stains or Past Leaks
Any area that has experienced water damage — even if it appeared to dry out — is a candidate for mold growth. Stains on ceilings or walls often signal ongoing moisture and mold behind the surface.
Health Symptoms
Unexplained allergies, respiratory issues, headaches, or fatigue that improve when you leave the building and return when you come back may indicate airborne mold exposure.
Peeling Paint or Wallpaper
Paint that bubbles, peels, or cracks — especially in bathrooms or near exterior walls — often indicates moisture accumulation behind the surface where mold is growing.
Condensation on Windows
Excessive condensation on windows indicates high indoor humidity — an environment where mold thrives. This is especially common in Columbus during temperature swings between seasons.
Why DIY Mold Removal Is Risky
close DIY Risks
- • Disturbing mold without containment sends millions of spores airborne — spreading it to clean areas
- • Bleach kills surface mold but doesn't penetrate porous materials where roots grow
- • Without identifying the moisture source, mold grows back within weeks
- • Exposure without proper PPE can cause serious respiratory illness
- • Incomplete removal can void future insurance claims
check Professional Advantages
- • Full containment prevents cross-contamination during removal
- • HEPA air scrubbing captures airborne spores throughout the process
- • Independent lab testing verifies successful remediation
- • Source identification and correction prevents recurrence
- • Proper documentation supports insurance claims
Mold Remediation FAQ
How do I know if I have mold behind my walls?
Common signs include musty odors, water stains, peeling paint, and unexplained allergy symptoms. The only way to confirm hidden mold is professional inspection with air quality testing. We collect samples and have them analyzed by an independent lab.
Is mold remediation covered by insurance?
If the mold resulted from a covered event — such as a burst pipe, storm damage, or appliance leak — remediation is typically covered. Mold from long-term neglect or maintenance issues may not be covered. We help you navigate your policy and handle all documentation.
How long does mold remediation take?
Most residential mold remediation projects take 3–7 days depending on the size of the affected area and the extent of material removal required. Lab results for clearance testing add 2–3 additional days. We provide a detailed timeline during our assessment.
Can I stay in my home during mold remediation?
In most cases, yes — our containment protocols isolate the affected area from the rest of your home. However, if the contamination is widespread or if household members have severe mold sensitivities, we may recommend temporary relocation.
Will mold come back after remediation?
Not if the moisture source is properly addressed. Mold requires moisture to grow — eliminate the moisture, eliminate the mold. We identify and correct the root cause as part of every remediation project, and we provide prevention recommendations.
Is black mold more dangerous than other types?
All mold should be taken seriously. While Stachybotrys (black mold) produces mycotoxins that are especially concerning, many mold species cause health problems. The species can only be identified through lab testing — which is why professional inspection is important.
