What documentation do insurers want for reclaimed structural timber?

Q: What documentation do insurers want for reclaimed structural timber?

Insurers and appraisers evaluating reclaimed structural timber generally want defensible, member-level documentation — species, dimensions, source structure, and a verifiable custody history — rather than a value asserted on a dealer's letterhead. For appraisals, underwriting, or claims, the documentation must withstand scrutiny by a party whose role is to challenge it, which is where unverifiable "trust me" records tend to fail.

Short answer: Underwriters and appraisers want the same thing a good buyer wants: a defensible, per-piece record — species, dimensions, source, and a verifiable custody history — rather than a value asserted on letterhead. For a claim or an appraisal, the documentation has to survive scrutiny by someone whose job is to doubt it.

Reclaimed structural timber shows up in insurance conversations two ways: as material being underwritten into a valuable build (a reclaimed-timber great room, a heritage restoration), and as the subject of an appraisal or a claim after something goes wrong. Both run into the same wall — someone whose job is to be skeptical is now reading your documentation.

What survives that scrutiny

An appraiser or underwriter isn't hostile, but they can't accept a number on faith. What holds up:

Per-piece records — species, dimensions, and source for the specific material, not a lot-level "antique barn wood, $X."
Independent verifiability — a record they can confirm without calling the dealer who has an interest in the value.
A dated, tamper-evident trail — so the documentation clearly predates the claim and wasn't assembled after the loss.
Honest scope — documentation that says what it covers (identity, custody) and what it doesn't (structural rating) reads as more credible, not less.

Why letterhead is weak here

A dealer's valuation letter has an obvious conflict: the person asserting the value is the person who profits from it. That doesn't make it wrong, but it makes it easy for an underwriter to discount. A per-member provenance record moves the basis from "the seller says it's worth this" to "here is the verifiable identity and history; value it from that."

Scope, stated plainly: a provenance certificate documents identity and custody and supports an appraisal or underwriting file — it is not itself an appraisal, a structural rating, or a guarantee of value or coverage. Those determinations rest with the appraiser, engineer, or insurer. Talk to your carrier about what they require; this is general information, not insurance advice.
