Cypress Creek & Concrete Mold
The Cypress-Fairbanks area sits astride Cypress Creek and its tributary network, which historically overflowed during major rain events. Hurricane Harvey deposited significant water across Stone Gate, Cypress Creek, Lake Shadows, and dozens of other NW Houston neighborhoods. Many garages that flooded in 2017 continue to show mold growth today — not from surface water, but from elevated soil moisture beneath the slab that wicks upward continuously.
Harris County's clay-dominant soil (classified as Lake Charles series in many Cypress-area locations) retains moisture for months after flooding and creates a persistent upward moisture gradient that bare concrete cannot block. This subsurface moisture, combined with Cypress's 80–90°F summer temperatures and high relative humidity, produces ideal conditions for mold and algae growth on garage floors.
Signs You Have a Mold Problem vs. Efflorescence
- Mold: Dark (black, green, or brown) spots or fuzzy growth; musty odor; grows in organic debris areas
- Efflorescence: White, powdery, or crystalline deposits; no odor; appears near edges and cracks
- Algae: Green or brownish-green growth near garage door openings or exterior-facing areas
Each requires different treatment. Efflorescence is a moisture migration indicator but is not a microorganism. Mold requires antimicrobial treatment before sealing. We identify the issue before recommending any solution.
Our Process for Cypress Homeowners
We assess your Cypress slab using in-slab moisture probes (ASTM F2170) and visual inspection. We map active mold locations and check for standing efflorescence.
EPA-registered antimicrobial applied to all affected areas. We allow full dwell time before mechanical surface prep begins — no shortcuts.
Mechanical removal of surface contamination and establishment of CSP 3 profile for maximum epoxy adhesion. Efflorescence areas are acid-etched before grinding.
High-build moisture-vapor-barrier primer, antimicrobial epoxy base, decorative broadcast flake, and polyaspartic topcoat. Rated for Harris County humidity cycles.
