MoldShield Pro
"We used MoldShield Pro for black mold behind our shower wall. Found it after a slow leak. Was panicking. They had a certified pro at our door by 9 AM the next morning, contained the whole area in one day, and saved us from what could have been a $10K problem."

Know Your Mold

Common Mold Types & Their Danger Level

Over 100,000 species exist. Here are the ones most likely in your home.

High Risk

Stachybotrys (Black Mold)

The most feared indoor mold. Produces mycotoxins that cause severe respiratory issues, chronic fatigue, and neurological symptoms. Appears dark green-black and slimy. Grows on water-damaged drywall, wood, and paper. Always requires professional remediation.

High Risk

Aspergillus

Over 180 species, several produce dangerous aflatoxins. Can cause aspergillosis — a serious lung infection, especially in people with weakened immune systems. Found in HVAC systems, insulation, and walls. Colors range from white to green to black.

Moderate Risk

Penicillium

Fast-spreading blue-green mold common after water damage. Triggers allergies, asthma attacks, and sinus infections. Spreads rapidly through air and can contaminate your HVAC. Not as toxic as Stachybotrys but still needs professional attention for large areas.

Moderate Risk

Chaetomium

Commonly found in water-damaged buildings. Starts white, turns dark over time. Produces a distinct musty odor. Can cause skin and nail infections. Often found alongside Stachybotrys in chronically wet drywall and ceiling tiles.

Lower Risk

Cladosporium

The most common outdoor and indoor mold. Olive-green to brown. Triggers allergies and asthma but rarely produces mycotoxins. Often found on fabrics, wood, and HVAC vents. Small patches can be DIY-cleaned; large areas need a pro.

Lower Risk

Alternaria

Common allergenic mold found in bathrooms, under sinks, and near windows. Appears dark brown with a velvety texture. Main concern is triggering allergies and asthma. Usually manageable with moisture control and cleaning for small areas.

GreenGuard Mold Solutions consistently offers the lowest starting prices. Always get 3+ quotes. Insurance may cover remediation if mold resulted from a covered event (pipe burst, appliance failure).

Insurance Guide

Does Your Insurance Cover Mold Removal?

The answer depends on what caused the mold. Here's what's typically covered and what isn't.

Sudden Pipe Burst

Water damage from a burst pipe is a "covered peril" in most policies. Mold that results from it is typically covered up to your policy limits.

Appliance Failure

Washing machine overflow, water heater burst, or dishwasher leak — if the appliance failed suddenly, resulting mold damage is usually covered.

Storm / Ice Dam Damage

Wind-driven rain or ice dams that damage your roof and lead to interior mold are covered under most homeowner policies.

Gradual Leaks / Neglect

A slow roof leak you ignored for months, condensation buildup, or failure to maintain your property — insurers consider this preventable and deny claims.

Flooding (Without Flood Insurance)

Standard homeowner policies do not cover flood damage. You need separate NFIP or private flood insurance for mold caused by external flooding.

High Humidity / Poor Ventilation

Mold from chronic humidity, poor ventilation, or lack of dehumidification is considered a maintenance issue and is excluded from coverage.

How to Maximize Your Mold Claim

1

Act fast. Document the water damage immediately. Insurers deny claims when homeowners wait too long to address the source.

2

Take dated photos. Photograph everything before cleanup. Timestamped photos are your strongest evidence for a claim.

3

File the claim first. Call your insurer before hiring a remediation company. Many policies require pre-approval or preferred vendors.

4

Get a professional inspection. An independent mold assessment creates documentation your adjuster can't easily dispute.

5

Check your mold cap. Most policies cap mold coverage at $5,000-$10,000. If your job exceeds that, consider a mold endorsement for next year.

Warning Signs

When Mold Becomes a Health Emergency

Most mold is annoying. Some mold is dangerous. Here's when you need to act immediately.

Respiratory Symptoms Near Mold

Coughing, wheezing, difficulty breathing, or worsening asthma within 10-15 feet of a moldy area. This suggests airborne mycotoxin exposure.

Children or Immunocompromised Residents

Kids under 5, elderly, pregnant women, or anyone with chronic illness are at 3-5x higher risk of severe mold-related health effects.

Mold Covers 10+ Square Feet

The EPA's threshold for professional remediation. Disturbing large mold colonies without containment spreads millions of spores throughout your home.

Musty Smell With No Visible Source

Hidden mold behind walls, under flooring, or in HVAC ductwork. If you smell it but can't see it, the problem is likely much larger than you think.

Mold Keeps Coming Back After DIY Cleaning

Recurring mold means the moisture source hasn't been fixed. Surface cleaning doesn't kill root systems in porous materials like drywall and wood.

Don't Wait. Mold Spreads Fast.

Every day you delay, mold colonies double. A $1,500 fix today becomes $6,000+ next month. Get matched with top-rated pros now.

FAQ

Your Questions, Answered

You can't tell by color alone. Black, green, and white molds can all produce mycotoxins. The only way to confirm is professional testing ($300-$800), which involves air sampling and surface swabs sent to a lab. If anyone in your home has respiratory symptoms, headaches, or chronic fatigue near a moldy area, treat it as potentially toxic until tested.
The EPA says DIY is only appropriate for mold covering less than 10 square feet (roughly a 3x3 area) on non-porous surfaces. Beyond that, you risk spreading millions of spores. Never DIY if: mold is in your HVAC, behind walls, covering more than 10 sq ft, or anyone has health symptoms. Improper removal often makes the problem 5-10x worse.
It depends. Most standard policies exclude mold or cap coverage at $5,000-$10,000. However, mold IS typically covered if it resulted from a “covered peril” like a sudden pipe burst or appliance failure. Mold from gradual leaks, neglect, or flooding (without separate flood insurance) is usually not covered. Document everything with photos and moisture readings.
Small jobs (bathroom, single wall): 1-2 days. Medium jobs (basement, crawl space): 2-4 days. Large jobs (whole house, HVAC): 5-10 days. Add 3-5 days for post-remediation testing and clearance. Reconstruction (drywall, flooring) is separate and can add 1-2 weeks.
IICRC certification (non-negotiable), liability insurance ($1M+ general liability), written scope of work before starting, containment protocols (negative air pressure, HEPA filtration), post-remediation clearance testing by an independent third party, and clear warranty terms. Red flags: no containment, no testing, prices that seem too good to be true.
No. “Black mold” is a color, not a species. Many harmless molds are black. The dangerous one people worry about is Stachybotrys chartarum, which produces mycotoxins. But Aspergillus (which can be green, white, or yellow) can be just as dangerous. Color tells you nothing — only lab testing identifies the species.
Yes. Mold behind walls, under flooring, and inside HVAC ductwork releases spores and mycotoxins into your air without any visible growth. A persistent musty smell is the most common indicator of hidden mold. If household members experience unexplained respiratory issues, headaches, or fatigue that improve when they leave the house, hidden mold is a likely culprit. Air quality testing can detect mold spores even when there's nothing visible.
Mold spores begin colonizing damp materials within 24-48 hours. Within 1-2 weeks, a small water stain can develop visible mold covering several square feet. HVAC systems accelerate spread by distributing spores throughout the house. This is why water damage restoration professionals recommend drying everything within 48 hours — once mold establishes, remediation costs 3-5x more than water damage cleanup alone.
It depends on the scope. Small contained jobs (single bathroom, one wall) don't usually require evacuation — the crew sets up negative air pressure containment to isolate the work area. For large jobs (whole-house, HVAC, or multiple rooms), evacuation is recommended, especially for children, elderly, pregnant women, or anyone with respiratory conditions. Your remediation company should advise you based on their containment plan.
“Mold removal” implies total elimination, which is impossible — mold spores exist everywhere naturally. “Mold remediation” is the professional term: returning mold levels to normal, safe concentrations. It involves containment, removal of contaminated materials, HEPA air filtration, antimicrobial treatment, and post-clearance testing to verify spore counts are within acceptable limits. Any company promising 100% mold removal is either misleading you or doesn't understand mold science.
