Cypress is a large unincorporated area of northwest Harris County where Cypress Creek and Little Cypress Creek flooded homes in the 2016 Tax Day flood and in Harvey. Away from the creeks, AC moisture and roof leaks drive most mold. Call the number on this page to be connected with a local mold remediation company in Cypress.

Mold services in Cypress
The two Cypress ZIP codes, 77429 and 77433, held about 200,000 people combined in 2020, although Cypress is not a city or even a census-designated place. It sits in Houston's extraterritorial jurisdiction about 20 miles in a straight line northwest of central Houston. Former farm and ranch land became one of the region's largest suburban areas after the 1980s, with master-planned communities starting in the early 1990s.
Creeks, storms and where water went
The Harris County Flood Control District lists Cypress, in the Little Cypress Creek watershed, among the hard-hit communities in the April 2016 Tax Day flood, and some homes in north and northwest Harris County that flooded then flooded again in the Memorial Day storm a month later. During Harvey, about 30 inches of rain fell along Cypress Creek. Homes near Cypress Creek and Little Cypress Creek, including Norchester and Lakewood Forest, flooded significantly, as did areas near FM 529, while many other parts of Cy-Fair stayed dry. That pattern matters: mold risk can differ a great deal from one subdivision to the next.
Everyday moisture in newer homes
Many Cypress homes are slab-on-grade with the air handler in the attic. A clogged condensate line, a rusted drain pan or ducts sweating in summer heat can wet ceilings and insulation without anyone noticing for weeks. EPA's advice is to keep indoor humidity under 60 percent and drain lines flowing.

Mold removal itself isn't permitted, but rebuilding after demolition needs a county permit. Renters should give written notice to the landlord; Texas Property Code 92.052 requires a diligent effort to repair conditions affecting health or safety once notified, if rent is current (general information, not legal advice). The nuisance program does not list mold specifically.
Texas's two-company rule
In Texas, both mold assessment and mold remediation require a TDLR license. A mold assessment consultant writes the protocol and hands it to you at least a day before work begins; a different company does the removal; the consultant verifies clearance; and you receive a Certificate of Mold Damage Remediation, which you would hand to a buyer if you sell within five years. When you call, you'll answer a few questions and be connected with an independent company that serves Cypress.
