Data Sources & Transparency
See where Verified Remediation gets its data: state licensing boards, Google Places ratings, insurance documents, and the zip codes behind service areas.
State Licensing Boards
Official regulatory agencies for mold professional licenses
We source license data from official state regulatory records. We re-check Florida's full state license list every week and the Texas state database every day. The New York and Louisiana records below are imported from each agency's published records and are not re-checked on a schedule. We check New York and Louisiana expiration dates every day. For DC we hold a December 2025 copy of the DC Department of Energy & Environment's public list of licensed mold professionals. It names people and their companies, with no license numbers or expiration dates, and we haven't re-checked it since.
Florida Department of Business & Professional Regulation (DBPR)
Visit DBPR- License Types: Mold Remediation (MRSR), Mold Assessment (MRSA)
- Data Fields: License number, holder name, status, expiration date, disciplinary actions
- Sync Frequency: Weekly on Sundays at 10:00 AM UTC, from DBPR's full published license list
Texas Department of Licensing & Regulation (TDLR)
Visit TDLR- License Types: Mold Assessment Company, Mold Remediation Company
- Data Fields: License number, company name, status, expiration date

Additional State Sources
- New York DOL: Open Data CSV export (2,300+ license records)
- DC DOEE: a December 2025 copy of its public list of licensed mold professionals (names and companies, no license numbers)
- Louisiana LSLBC: State licensing board database
In states where we do not hold the state's license records, we find providers through Google Places and verify insurance and industry certifications when providers supply them.
Industry Certifications

Ratings & Reviews
Third-party review data for trust signals
Google Places API
API DocumentationAll ratings and review counts are sourced directly from Google Places API. We do not host our own review system.
- Data Fields: Star rating (1-5), review count, business phone, website
- Sync Frequency: A daily batch of up to 50 listings, oldest data first; claimed profiles about weekly
- Tier A Threshold: 4.0+ stars with 5+ reviews
- No Manipulation: Contractors cannot edit their Google ratings
By using Google as our sole review source, we rely on Google's own spam detection. When Google removes a fraudulent review, the rating and review count we show catch up the next time that listing refreshes from Google.
Geographic Reference Data
Where our zip code, city, and county information comes from
GeoNames
The postal code export for the United States: 41,488 zip codes with their city, state, county, and map coordinates. This is what lets us tell whether a contractor actually covers your address.
geonames.orgUS Census Bureau
The official state FIPS codes. County names repeat across the country, so we combine these with GeoNames county codes to tell one Montgomery County from the seventeen others. Public domain.
census.govAttribution and license
Zip code, city, county, and coordinate data © GeoNames, from download.geonames.org/export/zip/, used under the Creative Commons Attribution 4.0 International License.
We have modified it. County codes are combined with Census state FIPS codes to form full five-digit county identifiers; roughly 60 zip codes keep the city name the postal service uses rather than the one GeoNames prefers, because that is the name people recognize for their own address; and records with no coordinates are left out. GeoNames does not endorse us or how we use the data.
We refresh this manually once or twice a year rather than on a schedule. Zip code boundaries barely move, and a surprise change to the data that decides which contractor hears about your project is worth noticing rather than absorbing silently.

Data Integrity & Quality
How we ensure data accuracy
- Data Normalization: All scraped data goes through standardization (name formatting, address parsing, license type mapping) to ensure consistency across sources.
- Fuzzy Matching: When the Texas state database returns a license we did not hold, we use 85% similarity threshold matching to prevent duplicate provider entries and link it to an existing profile. A new license number on Florida's weekly state list is added to our records without a listing; our team links it to one, for example when the contractor submits the number.
- Manual Review Queue: In Texas, providers with uncertain matches are flagged for manual review by our team before being published.
- Kill Switch Protection: In Florida, Texas, New York and Louisiana, where we hold the state's license records, a listing left without an active license after one expires is hidden from public pages. In every state, a business we cannot match to a Google business profile is hidden. Neither rule applies to a listing whose tier our team has set by hand.
- Tier Recalculation: Provider tiers are recalculated when a license expires, when our team approves insurance or a license, and when a listing's Google rating refreshes.
Our data pipeline holds more provider records than we publish: more than 10,000 professionals are publicly listed across all 50 states and DC.
