If you’ve discovered mold in your home or business, your first instinct may be to grab a bottle of bleach and start scrubbing. Unfortunately, that “quick fix” is one of the most common — and costly — mistakes we see homeowners make.
At Octagon Cleaning and Restoration, we’ve helped hundreds of property owners across Maine and New Hampshire tackle mold problems the right way. In this blog, we’re clearing the air about bleach, breaking down the science of mold remediation solutions, and helping you understand what really works when it comes to eliminating mold for good.
Myth: “Bleach Kills Mold”
Fact: Bleach may discolor mold and temporarily clean surfaces — but it doesn’t eliminate the root of the problem. Here’s why:
- Porous materials (like drywall and wood) absorb water — and mold grows within those pores. Bleach cannot reach deep enough to kill mold at its source.
- Bleach is mostly water. When applied to porous surfaces, the water soaks in and may actually feed mold growth over time.
- Bleach can cause toxic fumes and corrosion to materials and metals — leading to more damage.
What Really Works: Certified Mold Remediation Solutions
Professional mold remediation isn’t about covering up mold — it’s about removing it completely and preventing it from returning.
At Octagon Cleaning and Restoration, our process includes:
1. Moisture Source Identification
We use moisture meters, infrared cameras, and years of hands-on experience to locate hidden water leaks and humidity issues. Mold is just a symptom — moisture is the root cause.
2. Containment and Air Filtration
We isolate the contaminated area and use HEPA-filtered negative air machines to prevent mold spores from spreading throughout your home.
3. Safe Mold Removal
We remove contaminated building materials and clean all surfaces using EPA-registered antimicrobial solutions — not just bleach.
4. Drying and Prevention
Our team deploys professional-grade drying equipment to eliminate residual moisture and provides recommendations to prevent mold from returning.
Real-World Example: A Family in Portland, ME
“We thought we had it under control with bleach and a fan,” said Jill S., a homeowner in Portland. “The bathroom looked fine — but weeks later, the musty smell came back. Then my son’s asthma got worse.”
Jill called Octagon after a second DIY attempt failed. Our technicians discovered hidden mold inside the wall cavity due to an ice dam leak. We removed the damaged drywall and insulation, treated the space professionally, and had the space prepped for the reconstruction by our sister company, Octagon Construction. The family’s indoor air quality dramatically improved — and so did their peace of mind.
Common Mold Questions (Answered)
Q: Can I use vinegar instead of bleach?
A: Vinegar is less toxic than bleach and can kill some surface mold, but like bleach, it won’t solve deeper contamination in porous materials.
Q: How do I know if I need professional help?
A: If the affected area is larger than 10 square feet, if you smell a persistent musty odor, or if someone in your home has health symptoms — call a certified professional.
Q: Will mold come back after remediation?
A: Not if the source of moisture is fixed and proper prevention steps are followed. Octagon provides a full remediation plan and prevention guidance.
