Channelview conditions

Channelview is an unincorporated community in Harris County, about 20 miles from downtown Houston, on the northeastern curve of the Houston Ship Channel where the San Jacinto River forms the Old River. Petrochemical plants sit nearby, and businesses cluster along Interstate 10, Sheldon Road and Market Street. Being surrounded by water and humid Gulf air means interiors stay damp unless the AC keeps up, and older commercial roofs often let rain in long before anyone sees a stain. Large air handlers that run most of the year can grow mold in drain pans and ductwork.

For rebuilding after remediation, the Harris County Office of the County Engineer issues development permits in unincorporated areas; work in the 100-year floodplain needs drawings sealed by a Texas architect or engineer.

What affects the cost

The biggest drivers are the size of the affected area and how much material must be removed. Ceiling height, the need to move inventory, containment with negative air, HVAC cleaning and after-hours labor all add cost. Under Texas law you will pay two firms: the consultant for the protocol and clearance, and the remediation company for the work. HomeGuide's 2026 national ranges list $15 to $30 per square foot, and $2,000 to $10,000 for an HVAC system or ducts. Ask for every quote to follow the consultant's protocol so the numbers are comparable.

What happens when you call

A local mold remediation company asks what kind of building it is, how large the problem looks and whether people are still using the space. If the job will reach 25 contiguous square feet, the company needs a protocol from a separate assessment consultant and must notify TDLR at least five days before starting. Both firms must hand you TDLR's Consumer Mold Information Sheet before work begins. When removal is done, the consultant runs a post-remediation assessment, and within 10 days you should receive before-and-after photos and a Certificate of Mold Damage Remediation.
