The Inspection Happened Without the Inspector.
Now You Need the Letter.

Work got covered before the inspection. A wall came out years ago. The permit closed without a final — or never existed. When a building department, lender, or insurer asks for engineering documentation after the fact, a licensed Professional Engineer evaluates whether it can be verified remotely, and if it can, you get a sealed letter — usually without anyone driving to your property.

Missed & after-the-fact inspectionsRough-ins covered before inspection, missed footing or framing inspections, permits closed without a final — the covered-work letter your building department asks for.
Bearing walls & structural alterationsA wall was removed or opened and someone now wants engineering documentation of the header, posts, and load path.
As-built accessory structuresSheds, decks, pergolas, and carports needing documentation for a retroactive permit, insurance, or a sale.
Component certificationsWater-heater strapping, replacement windows and doors, attic-visible roof nailing — single-item letters, quickly.

Typically $295–$1,500 depending on scope — the engineer quotes your exact price before you pay anything.

We turn down the ones photos can't prove

Some things can be verified remotely: exposed framing, accessible connections, contractor pre-cover photos checked against permitted plans. Some things can't: work sealed behind drywall with no records, no access, and no evidence. When it's the second kind, we say so before you pay — and we talk about a site visit, inspection openings, or whether the letter you were asked for is even the right instrument. The engineer can also decline, refund, or require more information at any point. A letter the evidence doesn't support isn't worth sealing, and it wouldn't survive the building official's desk anyway.

Every case is reviewed personally by a licensed Professional Engineer. Photos carry timestamps and location metadata, a signed attestation opens every capture session, and the letter states its methodology plainly — including exactly what was and wasn't observable. Letters are furnished under the building code's acceptance-of-reports provisions, and our evidence protocol follows ICC and NFPA remote-inspection practices. Read our full methodology →

Tell us what you need

No payment, no commitment — a licensed engineer reads this and replies with either a scoped quote or an honest "this needs a site visit."

The single most useful thing you can tell us is whether the work is still visible — it decides almost everything.

How the letter holds up

Every letter states its basis: what was observed, what records were reviewed, what the reported inspection results were, and what remains concealed and unverified. It cites the applicable code and the jurisdiction’s own authority to accept reports from approved individuals, is signed and sealed by a licensed Professional Engineer, and is scoped to exactly the work evaluated. That precision is what allows building officials to accept these letters, and it is also why we sometimes tell you no.
