Mold Found in Your Home — What To Do RIGHT NOW
Discovering mold is alarming, but disturbing it makes it significantly worse. Close the door, keep your family out, and call TruRenu for a professional assessment before doing anything else.
Do These 5 Things Immediately
-
Do not disturb, scrub, or spray the visible mold
Disturbing mold causes spores to become airborne and disperse throughout your home within minutes. Scrubbing, blowing air on, vacuuming, or spraying any substance on visible mold before containment is established will spread contamination to areas that were previously unaffected.
-
Close the door to the affected area and keep family and pets out
Containing the mold to its current area is the most important immediate action. Close all doors and windows in the affected room. Keep children, elderly individuals, and anyone with respiratory conditions, asthma, or compromised immunity away from the space.
-
Turn off your HVAC system
Your heating and cooling system can draw airborne spores from the affected room and distribute them throughout your home's ductwork and into every other room. Turn off the system at the thermostat until professional containment is established.
-
Photograph the visible mold and any surrounding water staining
Document what you can see before calling. Note approximately when you first noticed the mold or the musty odor. Note any recent water events in or near that area — leaks, flooding, condensation problems. This information helps TruRenu assess the likely source and extent before arriving.

Call TruRenu — 888-867-4911
We assess the full scope of contamination — not just what is visible — using moisture meters and thermal imaging to find hidden mold sources before they are missed and grow further.
What NOT To Do When You Find Mold
These are the most common mistakes homeowners make when they discover mold — mistakes that expand the contamination and complicate the remediation.
-
Don't use bleach
Bleach is ineffective on porous materials like drywall, wood framing, and insulation where mold roots (hyphae) grow. Surface application kills surface mold while leaving the root structure intact, allowing rapid regrowth. Professional remediation uses EPA-registered biocides formulated for porous substrate penetration.
-
Don't use a shop vac or regular vacuum
Vacuums pull spores into their exhaust and release them directly into the air. A standard vacuum in a mold-affected area is one of the most effective ways to spread contamination throughout a home.
-
Don't paint over mold
Paint traps moisture and allows mold to continue growing behind the painted surface. The mold will break through the paint within weeks and will now be in an environment that is harder to remediate.
-
Don't open windows to "air it out"
Outdoor air currents can carry spores further into the structure rather than out of it. Professional air filtration with negative air pressure and HEPA filtration is the safe way to manage airborne spores during remediation.
-
Don't ignore a musty smell even if you cannot see mold
A persistent musty odor without visible mold almost always indicates hidden mold growth behind walls, under floors, or in ceiling cavities. Visible surface mold is often a fraction of the total contamination.
What Happens When You Call TruRenu
-
Phone assessment
We discuss what you have found, where it is located, any known water history in that area, and any symptoms your household has experienced. This helps us arrive prepared with the right equipment and scope.
-
Full inspection and moisture mapping
We inspect all visible mold and use moisture meters and thermal imaging to locate all hidden moisture sources — the active conditions that are feeding current and future mold growth. Stopping mold without stopping its moisture source guarantees regrowth.
-
Written scope of work
Before any work begins, we provide a written scope of work detailing exactly what will be removed, treated, and documented. You know what to expect before we touch anything.
-
Containment and air filtration
We establish containment barriers and set HEPA air filtration equipment to maintain negative air pressure in the affected area, preventing spore dispersal throughout the rest of your home during remediation.
-
Eco-safe remediation
We remove all contaminated materials and treat affected surfaces with biodegradable, EPA-registered biocides — no bleach, no harsh acids. Our products penetrate porous materials where bleach cannot reach.
-
Post-remediation verification and insurance documentation
We verify that contamination has been fully eliminated and document all work performed for your insurance claim and personal records.
What Happens If You Wait
Mold does not stay where you found it. Under ideal conditions — which Georgia's humidity provides for much of the year — mold can double its surface coverage every 24 to 72 hours. What appears to be a small patch of mold on a bathroom wall may have a colony behind the wall that is five to ten times larger than the visible surface.
The longer mold grows in a structure, the more materials must be removed. Drywall that is caught early can sometimes be treated in place. Drywall with extensive mold penetration must be removed entirely. The same applies to insulation, wood framing, and subfloor materials — each additional day of growth increases the scope of mandatory removal.
Mold also becomes progressively harder to remediate as it grows deeper into structural materials. Surface mold is the easiest to address. Mold that has penetrated the paper facing of drywall, colonized wood framing, or established itself in attic sheathing requires full material removal. Calling TruRenu when you first notice mold — not weeks later — is always the less expensive decision.
Mold in Atlanta Metro Homes
Georgia's hot, humid summers — with average humidity levels above 70 percent from May through September — create some of the highest mold risk conditions in the country. Crawl spaces in Gwinnett and Forsyth county homes are particularly susceptible: the combination of ground moisture, warm temperatures, and limited airflow creates near-ideal mold colonization conditions in homes without effective vapor barriers and ventilation.
Attic mold is the other leading cause of mold remediation calls in the Atlanta metro area. Inadequate attic ventilation — common in homes built in the 1980s and 1990s — allows warm, humid air from the living space to condense on attic sheathing. Over time, this creates ideal conditions for mold growth on the underside of the roof deck. Flowery Branch and Buford homes near Lake Lanier experience elevated attic moisture due to the persistent humidity off the lake. Gainesville and Cumming homes are similarly affected.
Post-water-event mold is TruRenu's most common remediation scenario. Homeowners who experience water damage — from burst pipes, flooding, roof leaks, or appliance failures — and do not get professional drying within 48 hours frequently call TruRenu 2 to 6 weeks later when mold becomes visible. If you have had any water event in the past 30 days and are now seeing or smelling mold, the two events are almost certainly connected — and the mold scope is likely larger than what is visible.

Mold Found in Home FAQs
All mold in a home should be taken seriously, but not all mold presents the same health risk. Common household molds like Cladosporium and Penicillium can cause respiratory irritation and allergic reactions in sensitive individuals. Stachybotrys chartarum (commonly called black mold) produces mycotoxins that can cause more severe health effects with prolonged exposure. More importantly, you cannot identify mold species by color alone — mold that appears black may not be Stachybotrys, and mold that appears white or green can still be harmful. Any visible mold in a living space warrants professional assessment.
Hidden mold is extremely common and often more extensive than visible surface mold. Signs of hidden mold include a persistent musty odor that cannot be eliminated with cleaning, unexplained respiratory symptoms (coughing, congestion, sneezing) that improve when you leave the home, visible water staining on walls or ceilings even without current leaks, soft or spongy spots in drywall, and warped or discolored baseboards. TruRenu uses moisture meters and thermal imaging to locate active moisture sources and map all contamination — visible and hidden — before any work begins.
Coverage depends on the cause. Mold that resulted from a covered water event — like a sudden pipe burst or storm damage — is typically covered by homeowner's insurance as part of the original water damage claim. Mold from gradual leaks, long-term moisture buildup, or flooding (without flood insurance) is usually not covered. TruRenu documents the source and timeline of mold growth to support coverage determinations and helps you understand your policy before work begins.
Most residential mold remediation projects take 1 to 5 days depending on the extent of contamination. A single bathroom or crawl space may be completed in one day; attic mold or whole-floor contamination may take 3 to 5 days. The process includes setup (containment and air filtration), removal of contaminated materials, treatment of all affected surfaces with EPA-registered biocides, and post-remediation verification. TruRenu provides a written scope of work before starting so you know exactly what to expect.
