CAN A PE STAMP SOMEONE ELSE'S DRAWINGS?
Yes. It's how a large share of American construction gets permitted — provided the stamp means something. This page is the line, drawn carefully.
Yes — a professional engineer may seal drawings prepared by someone else, but only after performing a genuine, independent review thorough enough to take responsible charge of the work: verifying the design, checking calculations, requiring corrections, and being free to refuse the seal. Sealing without that review — 'plan stamping' — is prohibited in every state and can cost the engineer their license. The drawings' author doesn't matter. The review does.
Why the practice exists at all
Modern construction runs on divided labor. Architects design buildings whose engineering is produced by consultants, manufacturers, design-builders and specialty engineers scattered across the country — while licensure is stubbornly state-by-state. A truss designer in one state, a design-build mechanical contractor in another, an architect's structural consultant in a third: the work product converges on a building in a fourth state, where none of them may hold a license. Third-party review and sealing by an engineer licensed in the project jurisdiction is the lawful bridge — the mechanism that lets national design capacity serve local accountability. Jurisdictions don't merely tolerate it; their rules contemplate it, and regulate how it must be done.
Which is why the honest version of this service is built like a review practice and not a signature shop. The question is never 'whose drawings are these?' It is 'has a licensed engineer, answerable for this work, actually engineered his way through it?'
Where the line sits
The line is responsible charge, and it is functional, not ceremonial. On the lawful side: the sealing PE receives the complete package, establishes the design criteria and code basis, independently checks the engineering — calculations recomputed or verified by alternative analysis, details traced against loads, interfaces examined — issues corrections with the authority to enforce them, re-reviews the fixes, and seals only when the work meets the standard they would sign their own name to. On the prohibited side: a fee changes hands, a seal lands on unreviewed paper, and nobody can produce a review file. Boards describe the second pattern with words like 'plan stamping' and treat it as unprofessional conduct, because the public reads a seal as a promise and the promise was empty.
A useful test when evaluating any sealing service — including this one: ask what happens when the drawings are wrong. If the answer involves correction lists, code citations and a reviewer who can say no, you're talking to a review practice. If nothing in their process can produce the answer 'we declined to seal it,' you're talking to a stamp mill with a website.
How we run it
SEALANVIL exists to run the lawful side of that line at speed. Every engagement opens with scoping — discipline, jurisdiction, completeness — and the assignment of a professional engineer licensed in the project jurisdiction. The review is documented: criteria established, calculations checked, corrections issued in writing where the work needs them, corrected sheets re-reviewed. The seal is applied by Apex Grid Engineering PLLC's licensing bench only when the responsible PE approves — a step we describe everywhere on this site with the same four words: review first, seal when approved.
That discipline is not a limitation on the business model. It is the business model. A market full of designers who need lawful, fast, jurisdiction-correct sealing does not need another signature for sale; it needs engineers willing to do the review properly and stand behind it. Willing — and staffed, licensed and organized to do it at the speed construction actually moves.
