Microbial growth is one of the most misunderstood problems Colorado Springs homeowners face. It thrives in hidden places—inside walls, beneath flooring, behind cabinetry, and in HVAC systems—often growing for weeks or months before any visible sign appears. By the time you see discoloration on a wall or smell a musty odor, the problem may be far more extensive than the surface suggests.
Colorado's unique climate—rapid temperature swings, spring snowmelt, summer storms, and high-altitude condensation—creates moisture conditions that many homeowners don't associate with growth risk. This guide helps you recognize the warning signs, understand when professional remediation is required, and protect your home from recurring problems.

Warning Signs You Shouldn't Ignore
Growth doesn't always announce itself with obvious discoloration. Watch for these indicators:
Musty or Earthy Odors
A persistent musty smell—especially in basements, crawlspaces, bathrooms, or areas near exterior walls—is often the first sign of hidden growth. This odor comes from microbial volatile organic compounds (MVOCs) released as organisms grow. If the smell persists after cleaning, the source is likely inside walls, under flooring, or in another concealed space.
Visible Discoloration
Dark spots, streaks, or patches on walls, ceilings, or around windows may indicate surface growth. Colors range from black and dark green to white, gray, or even orange depending on the organism and the surface material. Not all discoloration is growth—but any unexplained discoloration in a moisture-prone area warrants investigation.
Peeling Paint or Wallpaper
Moisture behind walls causes paint to bubble, crack, and peel. Wallpaper separates from the surface. These are signs that moisture has penetrated the wall cavity—and where there's persistent hidden moisture, microbial growth follows.
Allergy Symptoms That Worsen Indoors
If household members experience worsening allergy symptoms—sneezing, congestion, itchy eyes, respiratory irritation—that improve when they leave the house, indoor air quality may be compromised by airborne spores from hidden growth.

Condensation Patterns
Persistent condensation on windows, pipes, or walls indicates excess indoor moisture. While condensation itself isn't growth, it creates the conditions that allow growth to establish. Recurring condensation in the same locations points to areas at highest risk.
Warped or Buckled Materials
Flooring that buckles, baseboards that warp, or drywall that swells are signs of moisture saturation—the precursor to microbial contamination. These material changes indicate prolonged moisture exposure that likely extends into concealed areas.
Why Colorado Springs Homes Are Vulnerable
Many people assume Colorado's dry climate makes growth a non-issue. In reality, several factors create significant risk:
Rapid Temperature Swings
Colorado Springs can experience 40–50 degree temperature changes in a single day. These swings create condensation on cold surfaces, inside wall cavities, and on windows—providing the moisture growth needs to establish.
Spring Snowmelt
Rapid snowmelt pushes water against foundations, through window wells, and into basements and crawlspaces. This seasonal moisture intrusion is a primary driver of growth in lower levels of Colorado Springs homes.
Basement and Crawlspace Moisture
Many Colorado Springs homes have basements or crawlspaces that experience moisture intrusion from grade-level water, foundation cracks, or inadequate waterproofing. These enclosed, dark, poorly ventilated spaces are ideal environments for microbial growth.
High-Altitude Condensation Patterns
At 6,000+ feet elevation, the temperature differential between heated indoor air and cold exterior surfaces creates condensation patterns different from lower-altitude homes. This condensation often occurs inside wall cavities where it's invisible until growth has established.
Post-Damage Moisture
Water damage from burst pipes, roof leaks, appliance failures, or storm damage that isn't professionally dried creates growth conditions within 24–48 hours. In Colorado Springs, where homes may have older plumbing and are subject to extreme weather, water intrusion events are common.
What to Do If You Discover Growth

Don't Disturb It
Physical disturbance releases spores into the air, spreading contamination to other areas and degrading air quality. Don't scrub, scrape, or attempt to remove visible growth without proper containment and protective equipment.
Don't Use Bleach
This is one of the most persistent myths in home maintenance. Bleach does not kill growth on porous surfaces (drywall, wood, fabric). It only bleaches the surface color while growth continues beneath. On non-porous surfaces, bleach provides temporary surface cleaning but doesn't address the moisture source. Professional antimicrobial treatments are formulated specifically for each material type.
Ventilate If Safe
If the affected area is small and localized, improving ventilation can help reduce airborne spore concentration. Open windows in the affected room (weather permitting) and avoid running the HVAC system, which can distribute spores to unaffected areas.
Call Professionals
Contact an IICRC-certified growth remediation company for assessment. A professional evaluation determines the extent of contamination—including areas you can't see—and establishes the appropriate response protocol.
When Is It an Emergency?
Not all growth situations are emergencies, but some require urgent professional response:
Large Affected Areas (Greater Than 10 Square Feet)
The EPA recommends professional remediation for any affected area exceeding 10 square feet. Large areas indicate systemic moisture problems and potentially extensive hidden contamination beyond what's visible.
HVAC Contamination
If growth is found in or near HVAC components—ductwork, air handlers, drip pans, or registers—spores are being distributed throughout your home every time the system runs. This requires immediate isolation of the system and professional remediation.
Health Symptoms
If household members are experiencing respiratory symptoms, persistent allergies, headaches, or other health effects that correlate with being indoors, the situation should be treated urgently. Vulnerable populations—children, elderly, immunocompromised individuals—face elevated health risks.
Structural Compromise
Extensive growth on structural materials (wall framing, subfloor, roof decking) can compromise structural integrity. If you notice softened wood, crumbling drywall, or structural deflection in areas with growth, professional assessment is urgent.
Active Water Intrusion
Growth accompanied by ongoing water intrusion (active leak, persistent condensation, standing water) will continue expanding until the moisture source is eliminated. Remediation without source correction is ineffective.

The Professional Remediation Process
IICRC S520 is the industry standard for professional growth remediation. Here's what the process involves:
1. Assessment & Testing
Certified technicians evaluate the extent of contamination using visual inspection, moisture detection equipment (thermal imaging, penetrating meters), and professional experience. The assessment identifies all affected areas—including concealed contamination—and the moisture source driving the growth.
2. Source Correction
Remediation fails without moisture elimination. The water intrusion source—whether plumbing leak, foundation seepage, roof damage, HVAC condensation, or other cause—must be identified and corrected before remediation begins.
3. Containment
Engineering controls prevent cross-contamination during remediation:
Physical containment barriers (polyethylene sheeting) isolating the work area
Negative air pressure preventing spore migration to unaffected areas
HEPA air filtration capturing airborne particulates
HVAC system isolation
4. Removal & Cleaning
Contaminated porous materials that cannot be salvaged (affected drywall, insulation, carpet) are carefully removed and disposed of following industry protocols. Salvageable structural components are cleaned with approved antimicrobial treatments specific to the material type.
5. Drying & Dehumidification
Professional-grade equipment brings moisture levels back to standards that won't support future growth. Ongoing monitoring verifies target conditions are achieved and maintained.
6. Post-Remediation Verification
The job isn't complete until moisture readings confirm safe conditions and visual inspection verifies all contamination has been addressed. Documentation of the entire process is provided for your records and insurance.
DIY vs. Professional: What You Need to Know
When DIY May Be Acceptable
Affected area is less than 10 square feet
Growth is on non-porous surfaces only (tile, glass, metal, sealed countertops)
The moisture source is identified and corrected
No health symptoms are present in household members
No HVAC contamination is suspected
When Professional Remediation Is Required
Affected area exceeds 10 square feet

Preventing Future Growth
Growth prevention is fundamentally about moisture control. Eliminate the moisture, and you eliminate the conditions growth needs to survive.
Moisture Control
Fix leaks immediately — Even small drips create growth conditions in enclosed spaces
Improve drainage — Ensure grading, gutters, and downspouts direct water away from your foundation
Seal foundation cracks — Address any entry points for groundwater
Waterproof basements — Interior or exterior waterproofing prevents moisture intrusion through foundation walls

Ventilation
Bathroom exhaust fans — Run during and 30 minutes after showers; vent to exterior (not attic)
Kitchen exhaust — Use range hoods vented to exterior during cooking
Dryer venting — Ensure dryer vent is clear and properly connected to exterior
Crawlspace ventilation — Proper ventilation or encapsulation prevents moisture buildup
Dehumidification
Target 30–50% relative humidity indoors
Dehumidifiers in basements, crawlspaces, and other moisture-prone areas
Monitor humidity levels with a hygrometer (inexpensive and available at any hardware store)
Regular Inspections
Check under sinks monthly for leaks or moisture
Inspect basements and crawlspaces seasonally (especially after spring snowmelt)
Look behind and under appliances (washing machine, dishwasher, refrigerator) quarterly
Check attic for condensation, leaks, or discoloration annually
Insurance Coverage for Growth Remediation
Covered Perils
Growth remediation may be covered by your homeowners insurance if the growth resulted from a covered peril—a sudden, accidental event like:
Burst or leaking pipes
Appliance failure (water heater, washing machine)
Storm damage causing water intrusion
Fire suppression water damage
Maintenance Exclusions
Growth resulting from maintenance neglect is typically not covered:
Long-term unaddressed leaks
Poor ventilation
Chronic humidity issues
Foundation seepage from deferred maintenance
Policy Sub-Limits
Many Colorado homeowners policies include specific sub-limits for growth remediation—often $5,000–$10,000 regardless of actual costs. Review your policy's declarations page and consider endorsements for higher limits if your home has risk factors.
Comfort Restorations provides detailed documentation of the moisture source, extent of contamination, and remediation scope—critical information your adjuster needs to determine coverage.
Frequently Asked Questions
Can I test for growth myself?
Home test kits are available but have significant limitations—they often produce false positives or negatives and don't identify the type or extent of contamination. Professional assessment provides reliable results and actionable information. If you suspect growth but can't see it, professional moisture detection (thermal imaging) is the most effective approach.
Does growth always mean my home has a major problem?
Not necessarily. Small amounts of surface growth in bathrooms or kitchens can often be addressed with improved ventilation and cleaning. However, growth on walls, ceilings, or in hidden spaces indicates a moisture problem that needs professional investigation.
How long does professional remediation take?
Most residential growth remediation projects take 2–5 days depending on the extent of contamination and the areas affected. Reconstruction of removed materials (drywall, flooring) takes additional time. Comfort Restorations provides detailed timelines during assessment.
Is it safe to stay in my home during remediation?
This depends on the extent and location of contamination. Small, contained projects may allow occupancy in unaffected areas. Large-scale remediation or HVAC contamination typically requires temporary relocation. Your remediation specialist will advise based on your specific situation.
Will remediation solve the problem permanently?
Professional remediation eliminates existing contamination. Permanent prevention requires correcting the moisture source and maintaining proper ventilation and humidity levels. Without source correction, growth will return regardless of how thoroughly the remediation is performed.
