Residential Restoration Questions
Can I clean this mold myself?
While household cleaners might kill surface mold, spores remain dangerous, and cleaning improperly can spread contamination. Our IICRC‑certified technicians contain the area, remove infected materials, perform HEPA vacuuming, and correct moisture sources to prevent recurrence.
I get sick a lot. Is it mold?
Mold exposure is linked to respiratory symptoms—like coughing, sneezing, and wheezing—even in healthy individuals. We recommend a professional inspection to identify hidden mold and address it before symptoms worsen.
We had flooding, but didn’t see mold. Should we be worried?
Absolutely. Mold can form within 24–48 hours in unseen places—behind walls, under flooring, in vents. Even without visible mold, prompt mitigation is key.
How quickly can mold grow after water damage?
Under ideal moisture conditions, mold can begin colonizing within 24‑48 hours. That’s why we offer 24/7 response to start drying and remediation fast.
How do I know if it is black mold?
Visual identification isn’t reliable—black mold (Stachybotrys) looks similar to other molds. If you suspect it, we recommend third‑party testing for accurate identification.
What training and certifications do your technicians have?
We’re a fully IICRC‑ and ACAC‑certified firm, EPA‑ and OSHA‑trained, BBB‑accredited, and recognized with regional excellence awards.
What does your restoration process entail?
- Inspect & assess mold extent/environment
- Contain affected areas to prevent airborne spread
- Remove contaminated materials and treat surfaces
- Dry and clean using HEPA filtration and approved protocols
- Fix the moisture source, verify with clearance testing
How long does the restoration process take?
Timeframes vary based on extent and cause—remediation may take a few days for small cases, and a week or more for widespread issues.
How do you ensure safety and regulatory compliance?
We adhere to IICRC S520 protocols, use full PPE, air containment, HEPA scrubbing, and the latest equipment, overseen by certified supervisors.
How will I know if insurance will cover my damage?
We coordinate directly with insurers, documenting damage and using IICRC protocols to support your claim. Most mold cases tied to qualifying water damage are covered (deductible applies).
Is all mold the dreaded black mold?
No. There are many types—Aspergillus, Cladosporium, Penicillium, etc. “Black mold” is just one. Regardless, all indoor mold needs addressing.
Why don’t remediation companies do their own testing?
Self‑testing is a conflict of interest. We rely on independent third‑party labs for pre-/post-remediation clearance to ensure objectivity.
How much does this cost?
Costs depend on extent, materials, mold type, and underlying moisture issues. A small patch may cost hundreds; larger jobs or hidden mold/remediation can run into thousands.
Why should I use an IICRC‑certified firm?
IICRC certification signals adherence to rigorous industry standards, ensures proper documentation, gives insurer confidence, and reduces the risk of rework. We follow S520 (mold), S500 (water), and S700 (fire) guidelines.
Commercial Restoration Questions
How often should I have my HVAC system cleaned?
To maintain indoor air quality, most commercial HVAC systems should be inspected annually, with full cleaning every 2–3 years—or sooner in high-use or high-risk environments.
Are you licensed and insured?
Yes—Octagon Cleaning & Restoration is fully licensed, bonded, insured, and certified (IICRC, ACAC, EPA, OSHA). We hold BBB accreditation and regional industry awards.
Do you perform free estimates?
Absolutely—we offer free on-site assessments and estimates for residential and commercial properties in Maine & New Hampshire.
