Suspected mold — what to do right now
Suspected mold usually means there's also an active or past moisture problem. Both need to be addressed. Health questions about mold exposure are between you and a doctor — we're not medical professionals.
Step-by-step, safety-first.
These are the immediate steps EcoClean walks customers through over the phone. None of them involves DIY restoration — just keeping the situation safe and the damage contained until a professional crew arrives.
- Step 01
Identify the moisture source. Mold doesn't grow without one. Common sources: roof leak, plumbing leak, foundation seepage, condensation in a cold cavity, past water loss that wasn't dried.
- Step 02
Stop the moisture source if you can (shut off a leaking valve, repair a roof leak, address the failed appliance).
- Step 03
Limit access to the affected area — close the door, don't disturb visible growth.
- Step 04
Photograph the affected area before any cleanup.
- Step 05
Call EcoClean: (630) 945-4181 for an inspection. Remediation requires containment and a source fix, not just cleaning.
These make the loss worse.
- Don't spray bleach or household cleaner on visible mold — it doesn't address what's growing inside porous materials.
- Don't sand or scrub mold dry — that aerosolizes spores into the rest of the building.
- Don't run an HVAC system whose return pulls through the affected area.
- Don't take down drywall yourself if growth is widespread — containment matters more than speed.
When to call a plumber
- The underlying moisture source is plumbing — leaking supply line, drain, failed appliance line.
- A roof leak or window leak needs a roofer or contractor, not a plumber, but the same principle applies: fix the source.
When to call EcoClean
- Visible mold growth larger than a square foot.
- Mold growth on a porous surface (drywall, wood, fabric, carpet).
- Persistent musty smell with no visible growth.
- A past water loss that wasn't dried, now showing soft drywall or staining.
Things to know before you cleanup.
Containment with poly sheeting and HEPA-filtered negative air keeps spores from spreading to dry parts of the building during removal.
Air-quality testing is sometimes recommended before and after remediation, depending on the scope.
Antimicrobial application is a finishing step, not a substitute for removing contaminated material.
Walk through your situation.
Read the question, find the answer that matches your situation, follow the recommendation. The flow is built around what EcoClean asks customers over the phone.
- Question 01
Is mold visible, or is it a smell or symptom?
- Visible growth on a surface
Continue to question 02.
- Musty smell, no visible mold
Continue to question 04.
- Health symptoms — call a doctor
→ If you're concerned about health symptoms, call a doctor — that's outside what a restoration crew can advise on. For the building side, call us at (630) 945-4181 for an inspection.
- Question 02
How much visible growth is there?
- A small spot — less than a square foot
Continue to question 03.
- Larger than a square foot, or in multiple spots
→ Call us at (630) 945-4181. Remediation that size requires containment and source control — it's not just cleaning the visible spot.
- Question 03
Small spot of visible mold
Small surface growth on a non-porous surface (tile, glass, sealed metal) can often be cleaned with a household cleaner.
Small growth on a porous surface (drywall, wood, fabric) usually means the material under it is also affected — clean alone won't fix it.
- Non-porous surface
→ Clean the visible spot, then dry the area thoroughly and watch for regrowth over the next month. If it comes back, call us at (630) 945-4181.
- Porous surface
→ Call us at (630) 945-4181 — porous materials with mold growth usually need to come out, and we'll find the moisture source that fed it.
- Question 04
Musty smell with no visible mold
Musty smell usually means there's growth somewhere out of sight — behind drywall, under flooring, or in an HVAC system.
- I want it inspected
→ Call us at (630) 945-4181 — we'll inspect, find the moisture source, and recommend whether remediation is warranted.
Photos and notes the carrier expects.
Photograph the affected area before cleanup.
Capture the moisture source you identified.
Note how long the moisture has been present, if known.
Keep a list of materials that came out — the carrier will ask.
