Mold Inspection When Buying a Home in Texas: A Corpus Christi Buyer's Guide

Updated November 2026 · 6 min read

Buying a home in Corpus Christi, TX means buying into a humid, storm-exposed climate. A stain on the ceiling or a musty closet during a showing is worth a closer look. This guide explains how a mold assessment differs from a general home inspection, which Texas documents to ask the seller for, and what published inspection prices look like. It is general information, not legal or real estate advice.

Corpus Christi Mold Remediation is a free quote service, not a mold company. You describe the problem once, and independent mold inspection and remediation companies may reply with quotes. Some of those companies may pay to receive requests, and they reply on their own schedules.

A home inspection is not a mold assessment

Texas regulates the two separately. Occupations Code Chapter 1958, as amended in 2025, excludes real estate inspections from the mold licensing chapter. A mold assessment is different. Under §1958.001 it means an inspection, investigation or survey to evaluate mold, the development of a remediation protocol, or "the collection or analysis of a mold sample," and doing that for hire requires a TDLR mold assessment license (§1958.101).

So if your general home inspector notes possible mold, the next step for a closer look is a licensed mold assessor. Texas requires TDLR licenses for mold assessment and remediation work on 25 or more contiguous square feet (Occ. Code §1958.101–.102). Verify any company at tdlr.texas.gov/LicenseSearch.

Ask the seller for mold certificates

Texas has a specific rule here. Occupations Code §1958.154(b) says: "If a property owner sells property, the property owner shall provide to the buyer a copy of each certificate issued for the property under this section during the five years preceding the date the property owner sells the property." Those certificates are Certificates of Mold Damage Remediation (CMDR), issued on TDI form MDR-1 after licensed jobs.

What a certificate can tell you:

• That a licensed assessor stated "the mold contamination identified for the project has been remediated as outlined in the mold management plan or remediation protocol."
• Whether the assessor marked that the underlying cause was remediated so that it is reasonably certain the mold will not return from that cause.
• Which licensed companies did the assessment and the remediation.

Insurance Code §544.303 also says an insurer may not make an underwriting decision on a residential policy based on previous mold damage or a mold claim if the property was remediated, as shown by such a certificate, or was inspected by an independent assessor or adjuster who found no evidence of mold damage. A certificate does not guarantee coverage or a sale, but it is a useful record to have.

For other seller disclosure duties and contract deadlines, ask your real estate agent or a real estate attorney. This guide covers only the mold certificate rule.

What to look for in a Corpus Christi house

Local housing and storm history give you a checklist:

• Age. The median home in the city of Corpus Christi was built in 1982, and 46.1% of units predate 1980 (ACS 2020–24 5-year). In the 78404 ZIP area around Del Mar and Ocean Drive, the median build year is 1954 and about 82% of homes predate 1980. For pre-1978 homes, ask about lead paint and asbestos before walls are opened.
• Storm repairs. Harvey made landfall about 5 n mi east of Rockport on Aug 25, 2017 (NHC). Hanna made landfall on Padre Island on July 25, 2020, with a 6.24 ft surge at Bob Hall Pier (NHC). Ask what was repaired after each storm and when.
• Windstorm paperwork. Nueces County is in TDI's designated catastrophe area, where most roof replacements and major repairs need a windstorm inspection (certificates WPI-8 or WPI-8-E). Ask whether past repairs have certificates.
• Flood zone. The current Nueces County flood maps took effect Oct 13, 2022. Check the address at msc.fema.gov. Many coastal homes are raised, and ground-floor enclosures below the flood elevation are worth a look.
• The AC and the attic. Summer dew points average about 74°F (NOAA 1991–2020, Corpus Christi International Airport). As general building science, ducts and air handlers in hot attics can sweat. See AC and HVAC mold and attic mold.
• Walls near water. Stains low on walls, around tubs and below windows can point to a leak behind drywall. See wall and drywall mold.

How a buyer's mold assessment usually works

1. Hire a licensed assessor

   Check the license number on the TDLR search. Ask what the visit includes and whether samples are planned.

2. Moisture first, samples second

   TDLR says it is generally not necessary to identify the species of mold growing in a residence. A good report focuses on where the water is and how much material is affected. Our post do you need mold testing? explains when sampling helps.

3. Get the findings in writing

   If remediation is needed, the assessor can write a protocol. That document lets a separate company quote the work.

4. Get removal quotes from a different company

   In Texas, the company that assesses your mold and writes the protocol cannot be the company that removes it on the same project, and one owner can't hold both (Occ. Code §1958.155).

5. Use the paperwork in your decision

   Talk with your agent about how findings fit your contract. Timing depends on your contract, so book the assessment early.

What a mold inspection costs

No current Corpus Christi price list was found. Fixr's national figures (Jan 2025) put a mold inspection at $450–$800 (average about $500), inspection only at $300–$600, and an air test at $500–$700. If remediation follows, Fixr (Aug 2025) gives $1,500–$9,000 overall and This Old House (Mar 2026) gives $1,200–$3,750. These are published national estimates, not quotes. Our Corpus Christi mold remediation cost guide has the full table and a calculator. Quotes come from independent companies, not this site.

If the seller offers to fix it

Ask for the scope in writing. On a job of 25 contiguous square feet or more, that means a protocol from a licensed assessor, a work plan from a separate licensed remediator, and a certificate at the end. Ask for the Certificate of Mold Damage Remediation (TDI form MDR-1). Insurers can't make underwriting decisions based on remediated mold damage when you have it (Ins. Code §544.303), and you must give buyers copies from the last five years (§1958.154(b)).

To get quotes for an assessment or removal, describe the house and what you saw, or call (361) 247-3040. More on assessments is on our mold inspection and testing page.
