Your mold removal work involves containment of the affected area, identifying the moisture source, removing uncleanable material and drying whatever can stay.
Related types of work include mold cleanup, mold mitigation, mold remediation and mold abatement. Your scope should cover damp materials, visible mold growth and the underlying humidity issue or water intrusion.
Disposal may be necessary for porous drywall, ceiling tile and carpet. Cleaning and drying are possible for many non-porous surfaces.

Moisture and material shape the cleanup plan.

A moisture meter helps locate your moisture source and affected materials, with a thermal imaging camera used when helpful.
Build your containment barrier using poly sheeting. Negative air pressure and a HEPA air scrubber, an air filtration device, limit particles moving into clean rooms.
Workers make use of protective equipment. Drywall removal or other demolition of damaged porous materials may be needed.
Remaining non-porous surfaces are cleaned using damp wiping along with a HEPA vacuum. Use moisture readings, a dehumidifier and air movers to guide drying.
For post-remediation verification, an independent assessor may check visually, conduct air sampling or perform clearance testing.
Call any hour. A mold cleanup specialist answers, explains the next steps and discusses the moisture problem with you.
Your affected materials can spread mold spores and dust to clean rooms when disturbed, which is why containment matters.
Pulling up carpet or cutting into drywall may release particles. HEPA filtration with negative air pressure helps restrict movement.
Even when surfaces appear dry, moisture may remain in subfloor, framing or insulation. Use moisture readings to identify the affected area.
Mold can trigger allergy and asthma symptoms in some people. According to the CDC, higher risk applies to people with asthma, lung disease or weakened immune systems.
Black mold and toxic mold are search terms. According to the CDC, mold color cannot tell you the level of risk.

These are published national ranges, not a quote. An on-site assessment establishes the actual price, which you should hear explained prior to the start of work.
For insurance coverage, both the cause of moisture and policy matter. Long-term leaks, neglect and humidity are often excluded or limited, whereas a sudden water event may qualify if covered.
South Dakota law (SDCL 43-32-8) says a residential landlord is to keep the premises in reasonable repair and fit for human habitation, and a lease cannot waive that.
Ask about coverage for the water event, any mold sublimit, and insurance claim requirements before you have materials taken out.
South Dakota law (SDCL 43-4-38 and 43-4-44) has sellers of homes with up to four family units give buyers a property condition disclosure statement before a written offer. The state form includes a Mold line under hazardous conditions.

The EPA notes that occupants can often clean an area smaller than about 10 square feet after resolving the water problem. HVAC involvement, contaminated water and larger affected areas require professional help.

Your property needs its own assessment. The area figures do not establish the age or condition of your building. Plan access around the rooms and materials that need attention.
Keep dated photos and repair records. Ask who can authorize access, who will repair the moisture source and which records you should receive when cleanup is complete.
