If you discover mold in your home, the natural reaction is to try and clean it up yourself. However, when it comes to toxic black mold (Stachybotrys chartarum), DIY removal is not safe. Disturbing black mold can release dangerous mycotoxins into the air, putting your familyโs health at risk.
For homeowners in Barrington, Portsmouth, and the Seacoast region of New Hampshire, professional mold remediation is critical. At Octagon Cleaning & Restoration, our certified experts follow strict containment and removal protocols to eliminate black mold safely and thoroughly.
Why Black Mold Requires Professional Removal
Black mold thrives in damp environments caused by water damage, humidity, or flooding. Unlike surface mold that can be wiped away, black mold penetrates porous materials and releases microscopic spores when disturbed. These spores contain mycotoxins that can cause:
- Respiratory issues (coughing, wheezing)
- Eye and skin irritation
- Chronic fatigue
- Neurological symptoms (brain fog, headaches)
- In severe cases, lung bleeding or infections
What Does Black Mold Look Like?
Itโs important to know that not all black-colored mold is the dangerous โtoxic black mold.โ Mold appears in various colorsโgreen, brown, white, pink (often bacteria), and more. However, Stachybotrys chartarum is typically dark greenish-black and slimy, often found in areas with long-term moisture issues, such as:
- Basements with past flooding
- Around leaky windows or roofs
- Inside wall cavities with hidden water damage
- On insulation, drywall, or wood framing
Signs You May Have Black Mold in Your Seacoast Home
- Persistent musty odor, especially in basements or crawlspaces
- Unexplained allergy-like symptoms that worsen indoors
- Water stains or discoloration on ceilings and walls
- Visible dark patches on drywall, wood, or insulation
What Should You Do If You Suspect Black Mold?
1. Do Not Disturb the Mold
Attempting to scrub or remove mold yourself can worsen the contamination. Airborne spores can spread throughout your homeโs HVAC system and other areas.
2. Schedule a Professional Mold Inspection
At Octagon Cleaning & Restoration, we conduct thorough mold assessments using moisture mapping and air sampling to determine the extent of the infestation.
3. Follow IICRC-Certified Remediation Procedures
Our team follows guidelines set by the Institute of Inspection Cleaning and Restoration Certification (IICRC), ensuring safe containment, removal, and HEPA filtration to eliminate spores and mycotoxins.
4. Consider Temporary Relocation
For severe black mold cases, we recommend temporarily relocating until remediation is complete. Prolonged exposure can have cumulative health effects.
5. Treat Personal Belongings
Items like clothing, linens, and upholstered furniture exposed to mold spores should be professionally cleaned or discarded if necessary. We provide guidance on what can be salvaged.
