Contact
The National Drywall Authority maintains this contact channel for service seekers, licensed contractors, industry researchers, and professionals operating within the drywall and interior finishing sector across the United States. Inquiries routed through this office concern directory listings, professional qualifications, regulatory references, and sector-specific classification questions. Understanding what information to include — and what response timelines apply — allows correspondence to be resolved efficiently.
What to Include in Your Message
Effective correspondence with this office requires structured, specific information. Vague or incomplete submissions delay routing and extend resolution timelines. The following categories define what each type of inquiry should contain.
For directory listing inquiries:
- Business legal name and primary operating state
- License classification held (e.g., drywall-only subcontractor, general framing contractor, specialty firewall installer)
- Applicable licensing body — such as a state contractor licensing board or a jurisdiction-specific building authority
- Trade certifications relevant to the inquiry, including any Gypsum Association (GA) compliance references or ASTM International standard alignments (e.g., ASTM C840 for application of gypsum board, ASTM C36 for gypsum wallboard specifications)
- Project scope range — residential, light commercial, or heavy commercial/industrial
For regulatory and standards questions:
- Specific code reference at issue — for example, International Building Code (IBC) Section 2508 governing gypsum board application, or OSHA 29 CFR 1926 Subpart Q addressing concrete and masonry construction as it intersects with interior partition work
- Jurisdiction in question (state and municipality)
- Nature of the inquiry: permitting, inspection protocol, fire-resistance assembly classification (Type I through Type V construction under IBC Chapter 6), or material specification
For research and data inquiries:
- Organization affiliation or professional role
- Specific subject area — for example, fire-rated wall assembly standards, impact-resistant board classifications, or moisture-resistant substrate requirements in wet-area applications
- Intended use: academic, commercial, regulatory review, or contractor qualification
Messages that distinguish between Type X and Type C gypsum board applications, or that specify whether the inquiry concerns load-bearing vs. non-load-bearing partition assemblies, receive faster substantive responses because they arrive pre-classified.
Response Expectations
Correspondence submitted with complete information as outlined above typically enters the routing queue in a timely manner. Substantive responses for standard directory and classification questions are addressed within 3 to 5 business days. Inquiries involving regulatory interpretation — particularly those touching OSHA fall protection standards under 29 CFR 1926.502, fire-resistance-rated construction under IBC Chapter 7, or ADA accessibility dimensions for drywall-finished corridor and doorframe clearances — may require additional review time and are not subject to expedited handling.
This office does not provide legal advice, contractor licensing decisions, code compliance determinations, or binding regulatory opinions. Responses addressing regulatory framing reference named public standards and agency publications only — NIST, OSHA, the International Code Council (ICC), the Gypsum Association, and ASTM International among them. Interpretation of those standards in specific enforcement contexts rests with the applicable authority having jurisdiction (AHJ).
Incomplete submissions — those missing jurisdiction, license classification, or a specific subject reference — are returned with a request for clarification rather than processed speculatively.
Additional Contact Options
Professionals seeking to verify a contractor's standing against a state licensing registry should contact the licensing authority in the relevant state directly. Across the 50 states, contractor licensing for drywall and interior finishing work is regulated at the state level, with no single federal licensing body. California's Contractors State License Board (CSLB), Florida's Department of Business and Professional Regulation (DBPR), and Texas's Texas Department of Licensing and Regulation (TDLR) represent three distinct licensing structures with differing scope-of-work definitions for drywall subcontractors.
For permitting questions, the authority having jurisdiction — typically the local building department — holds final determination over permit requirements for partition construction, fire-rated assembly compliance, and inspection scheduling. The Drywall Listings section of this site provides contractor classification references that may assist in identifying relevant trade categories before contacting a local AHJ.
Standards documents referenced in correspondence — including GA-216 (Application and Finishing of Gypsum Panel Products) and ASTM C840 — are available directly through the Gypsum Association and ASTM International respectively.
How to Reach This Office
Correspondence is accepted through the submission form hosted on this domain. No postal address is published for unsolicited physical mail. Phone intake is not available for general inquiries; all substantive correspondence is handled through the written submission channel to ensure documentation and proper routing.
When submitting, use the message structure described in the first section of this page. Submissions that arrive with a clear subject classification — directory, regulatory reference, research, or listing verification — are routed to the appropriate review process without a secondary intake step.
For inquiries related to the scope and purpose of this directory, the Drywall Directory Purpose and Scope page provides classification boundaries, coverage methodology, and the standards framework that governs which contractor categories and project types fall within this resource's defined scope.
