Mold is a moisture problem first. We find out why it is growing, contain the area so spores do not spread through the house, remove it, and correct the conditions that let it start.
Spraying mold with bleach and painting over it is the most common repair we are called in to redo. Mold grows where there is moisture and something to feed on, and drywall, wood framing, carpet backing and dust all qualify. Unless the water source is found and fixed, it grows back, usually behind the fresh paint.
Proper remediation is methodical. We set up containment and negative air pressure so disturbed spores are captured instead of spread, remove materials that cannot be cleaned, HEPA-vacuum and treat what remains, and dry the area to a normal moisture level. Then we tell you what caused it and what will keep it from returning.
Visual inspection, moisture meters and thermal imaging to find both the growth and the water feeding it.
Plastic barriers and negative air machines isolate the work area from the rest of your home.
Air scrubbers run throughout the job to capture airborne spores and dust.
Moldy drywall, insulation, carpet and trim bagged and removed. Framing is cleaned, sanded or treated in place.
HEPA vacuuming and antimicrobial treatment of remaining surfaces, with encapsulant where appropriate.
Drying, recommendations for the root cause, and reconstruction of the removed finishes.
How it works
We identify how far the growth extends and where the moisture is coming from. If independent testing makes sense, we will say so.
The work area is sealed and placed under negative pressure before anything is disturbed.
Unsalvageable materials come out, and remaining surfaces are HEPA-vacuumed, cleaned and dried.
The moisture source is addressed and the area is rebuilt with appropriate materials.

Nebraska summers are humid, and a cool basement surrounded by damp clay soil is exactly where that humidity condenses. Finished basements hide it behind drywall and under carpet. In winter the problem moves upstairs: warm, moist air leaks into cold attics, frosts the underside of the roof deck, and shows up as dark staining on the sheathing by spring. Both are fixable, and both start with controlling moisture.

FAQ
Straight answers to what people ask us most.
Not always. If you can see mold, you already know it is there, and the priority is finding the moisture source and removing the growth. Testing is useful when there is an odor with no visible source, for real-estate transactions, or to confirm a remediation was successful. For post-remediation clearance, an independent third-party assessor is the best practice.
Mold affects people differently. Those with allergies, asthma or weakened immune systems tend to be more sensitive, and anyone with ongoing symptoms should talk with a doctor. Regardless of type or color, indoor mold growth should be removed and its moisture source corrected.
Small areas on hard surfaces, generally under about ten square feet, can often be cleaned by a homeowner. Larger areas, growth inside walls or HVAC systems, or mold from contaminated water are better handled with professional containment so the cleanup does not spread it.
It depends on the policy and the cause. Mold that results from a covered water loss is sometimes covered, often with a dollar limit. Mold from long-term humidity or neglected maintenance usually is not. Your agent can tell you what your policy says.
