SSTAMPFORGEPE sealing, explained.
An educational library

Professional sealing,
in plain English.

Most projects meet the professional engineer's seal at the worst possible moment: at the permit counter, in a comment letter, or one revision before a deadline. This library exists so the seal is something you understand before you need it — what it is, what it is not, how review works, and what a reviewer will ask of your drawings.

Stampforge publishes explanations, not offers. The guides below cover the mechanics of PE review and sealing the same way a good reviewer explains them across the desk: directly, in order, and with the limits stated as plainly as the benefits.

No prices, no promised timelines, and no coverage claims appear anywhere in this library — for reasons the guides themselves explain.

The short version

The seal, in three sentences

A professional engineer's seal is a licensed engineer's formal attestation, applied to engineering documents, that the work was prepared under that engineer's responsible charge and meets the standard of care for the profession. It is earned through review — an engineer examines the drawings and calculations, requires corrections where the work falls short, and seals only when satisfied. A seal is never a guarantee that a permit will issue; the authority having jurisdiction makes that decision.

Everything in this library expands one of those three sentences. The guides walk the full path: how a review engagement is scoped and quoted, how jurisdiction decides who may seal your plans, what reviewers look for, why corrections are a normal part of the process rather than a failure of it, and what drives the cost and pace of a review when no honest person will quote either one from a podium.

Why this library is written the way it is

Engineering review is a regulated professional service, and the rules that govern it are not marketing inconveniences — they are the substance. A reviewer may only seal work in a jurisdiction where they are licensed. A firm may only offer services its registrations support. A seal may only follow a genuine review. Any website that skips past those facts to quote a price or promise a turnaround is telling you something about how it will treat the review itself.

So this library states the mechanics and stops where the mechanics stop. Eligibility is confirmed project by project. Cost and timeline live in a written scope and quote, not on a webpage. The seal follows the review, never the other way around. If that reads as less exciting than the alternatives, it is also what the inside of a well-run review actually looks like.

Reading done — drawings ready?

If you arrived here with a plan set, a comment letter, or a permit deadline, the contact page explains what a review inquiry should include and where it goes. Project reviews are coordinated there, not sold here.
