Why North-Facing Brick Develops Growth in DFW
DFW's humid subtropical climate, combined with shaded north-facing exposures that receive minimal direct sunlight, creates ideal conditions for mold, mildew, and algae to take hold on brick and siding. Visible as dark streaking or a greenish-black tint, this growth is especially common on homes with mature landscaping or shade structures that further extend how long moisture lingers against the wall surface after rainfall.
Brick's porous surface makes it particularly susceptible to embedded growth compared to smoother siding materials, since spores can take hold in the mortar joints and slightly porous brick face.
Professional Soft Washing Removes Growth Safely
High-pressure washing alone often fails to fully address mold and mildew because it can spread spores without killing the root organism, and on brick, excessive pressure risks damaging mortar joints. Professional soft washing applies biodegradable algaecide and mildewcide solution at low pressure, allowing it to dwell and kill the organism at the root before a low-pressure rinse removes dead growth and residue.
