VERIFIED DIRECTORY · UPDATED 2026-08-13
Most contractor lists are paid placement. This one lists 262 providers across 16 US flood regions — the Gulf and Atlantic coasts, the Mississippi and Missouri river valleys, the Great Lakes, the Great Plains and the Southwest — each confirmed against at least two independent sources. Where a state licenses contractors (Louisiana), the license is checked against the board; where it does not (Texas), BBB accreditation and structural-mover association membership stand in. 133 are Tier 1, 56 carry a verifiable state license.

No providers match.
Each provider is corroborated across at least two INDEPENDENT sources (Google Business Profile/Maps, BBB, state licensing board, structural-mover association, local chamber, press), the company's own website and lead-broker aggregators (Angi, Houzz, Thumbtack, HomeAdvisor) do NOT count toward the two. Google ratings pulled via the Serper Places API. Texas has no statewide general-contractor license, so stateLicense is legitimately null for most Texas firms; BBB accreditation and TASM membership are the trust anchors there. Louisiana licenses contractors through the LSLBC, so a state license number is captured where verifiable. No credential, license number, principal name, or review figure was invented, unverifiable fields are null with an editorial note. Providers flagged fatally (accreditation suspended, under 6 months old, self-described lead-generation front, or a perfect rating with zero credential trail) were excluded and are listed in the methodology, not the roster. August 2026 commercial layer: providers of types C, D and E were verified against government and institutional records first - FEMA case studies, City of Indianapolis contract records, Indiana DNR/DHPA Qualified Professionals Roster, USACE ERDC test reports, the ASFPM certified-products list, Indiana Landmarks project credits and university contract awards - because in this category a company's own case studies are marketing, not evidence. Two product-certification rules are applied strictly: FM Approved is a property of a specific model, never of a brand, and FEMA does not approve or certify any flood barrier product, so any vendor advertising a 'FEMA approved' barrier is overstating. Where the FM Approvals database blocked automated lookup, certification is recorded as manufacturer-stated and unverified rather than as confirmed or absent. Certification verification was strengthened late in the build when the National Flood Barrier Testing and Certification Program's certified-products register (floodmitigationcertification.org) was located. It is the authoritative public list of products certified to ANSI/FM 2510, and it lets a claim be confirmed or refuted at model level rather than recorded as unverified. Manufacturers on the register include ILC Dover, PS Industries, Presray, AquaFence, Geodesign and Flood Control International; several widely marketed brands are absent from it.
Not affiliated with any contractor. Listing is not an endorsement, always verify the current license, insurance and references yourself before signing. Ratings shown are pulled per platform and never blended into an invented average.
In Louisiana, verify the contractor’s license number against the LSLBC (state licensing board). Texas has no statewide general-contractor license, so use BBB accreditation, Texas Association of Structural Movers (TASM) membership, and separate Google/BBB reviews. For backwater valves, the installer must hold a TX Master Plumber (TSBPE) license. Every provider here cleared at least two independent sources.
An elevation (structural-moving) contractor physically raises the whole house above the Base Flood Elevation, the strongest mitigation and the biggest job. A floodproofing installer handles flood vents, deployable barriers, backwater valves, sump pumps, and drainage, lower-cost measures that reduce damage but do less for your NFIP premium.
No. This is an independent directory with no lead form and no paid placement. Providers are ordered by verification strength, not by spend. 133 are Tier 1 (verified plus a state license or BBB/association credential).
