Arlington sits in Tarrant County where summer dew points regularly exceed 70°F and DFW averages more than 10 significant hail events per year. Severe storms between March and June drive flash flooding along Johnson Creek and Village Creek. When roof hail damage or floodwater enters a structure, humidity inside walls can exceed 60% for weeks.
Common Arlington mold triggers include HVAC condensate overflows in 1980s-90s subdivisions like Woodland West, slab foundation movement from Tarrant County's expansive clay soils creating gaps at slab edges, and poor attic ventilation in dense residential tracts near Pantego where summer attic temps exceed 140°F.
Texas requires separate DSHS licenses for mold assessment and remediation under Occupations Code Chapter 1958. The same company cannot assess and remediate the same project. Ask to see both DSHS credentials and current IICRC S520 certification before any work begins — unlicensed remediation can void your insurance claim.
