Professional mold inspection serving Ann Arbor and surrounding areas.
Mold inspection in Ann Arbor answers the question the city’s housing stock forces: is the musty smell a surface problem or a hidden colony inside the wall? The local conditions that make this question hard are exactly the conditions inspections are built for — plaster assemblies in the Old West Side and Water Hill that wick water sideways and hide growth behind intact surfaces, Washtenaw clay keeping basements damp without any visible event, high water tables along the Huron humidifying crawlspaces, and ice dam seasons pushing melt into wall cavities that stay wet until spring. Water Damage Pros US inspects Ann Arbor homes and rentals with moisture mapping, thermal imaging, and lab-analyzed sampling that turns suspicion into a scoping document.
Plaster is the master hider. Wood-lath and rock-lath walls in the historic core hold moisture inside the assembly — a colony can cover six feet of cavity behind plaster that looks perfect until a key fails. Inspections there lean on thermal imaging and targeted bore holes rather than visual checks.
Clay soil is the steady feeder. Washtenaw clay wicks groundwater against foundations year-round, and basements in the Malletts Creek corridor and beyond grow colonies on contents and finished walls with no leak, no flood, no visible water — just chronic dampness owners normalize.
The rental cycle is the accelerant. August turnover near Central and North Campus regularly surfaces growth that sat through a wet spring in unoccupied units; inspections at turnover protect landlords before incoming tenants sign.

| Visual + moisture mapping inspection | $300 – $500 | Full-home scan, written findings |
| Air sampling (3-sample set) | $150 – $350 | Indoor/outdoor comparison, lab report |
| Additional air samples | $50 – $100 each | Per extra room or floor |
| Surface sampling | $75 – $150 each | Tape or swab at suspect growth |
| Borescope cavity checks | $100 – $300 | Small holes at confirmed wet spots |
| Rental turnover inspection | $250 – $450 | Per-unit documentation |
The same discoveries surface across Washtenaw County inspections: colonies on basement contents stored against damp foundation walls; growth inside eave cavities where ice dams wet batts every winter; crawlspace mold humidifying entire first floors; bath-fan ducts disconnected in attics, raining condensation onto insulation; and hidden colonies behind basement finish walls that took Malletts Creek water and dried on the surface only. Each finding maps to a moisture source — and every source goes in the report, because remediation without source resolution is a re-growth guarantee.
Century homes in the Old West Side and Burns Park, mid-century ranches over Malletts Creek, and student rentals near campus all carry mold risk profiles that standard home inspections do not surface. A mold-specific inspection before closing — moisture mapping, sampling, crawlspace and attic access — costs a fraction of discovering a $6,000 remediation after move-in, and gives buyers leverage or peace of mind either way.
The smell is real even when the wall looks clean. Sampling tells you whether the spores in your air are coming from a hidden colony or just an open window — and that difference changes what you do next.

When you smell must but can't see growth, when anyone in the home has unexplained respiratory symptoms, after any flood or ice dam event, or before buying a home in Ann Arbor's older districts.
Moisture mapping finds the wet cavities, thermal imaging shows the temperature patterns, and borescope holes peek inside walls at confirmed suspect spots — sampling confirms species.
Yes — spore counts inside versus outside tell you whether hidden growth is active, and which species. It's the difference between guessing and scoping a real remediation.
Yes. Turnover inspections near Central and North Campus document conditions between tenants, which protects both landlords and incoming residents.
Visual inspection with moisture mapping runs $300–$500; adding lab-analyzed air and surface sampling runs $400–$700 depending on sample count.
