About Datum
Evan Marsh spent fifteen years building and remodeling Columbus houses before founding Datum in 2016. 4,800+ inspections later, the operating idea hasn't changed: an inspection report should read like evidence — specific, located, severity-coded, priced where honest — because that's what people negotiate six figures over.
The team
Owner & lead inspector
Fifteen years framing and remodeling houses before a decade inspecting them — Evan reads a house from the framing out. He wrote Datum's reporting standard: describe what is, say what it means, price what's known, and skip the drama.
Inspector
Former insurance field adjuster — Dana has documented more storm-damaged roofs than anyone should. She handles most of Datum's WDI reports and is the reason our roof sections read like claims evidence.
Client coordinator
Reese answers within two rings during business hours, keeps the 48-hour radon pickups on schedule, and makes sure every report goes out before 9 p.m. — or you'd hear from them first.
Demo note: Datum Home Inspection Co. is a fictional company built as a design sample. The licenses, certificates and registration numbers shown are illustrative sample content — they are not real credentials and reference no real person or certifying body.
How we report
01
A hairline settlement crack is a hairline settlement crack — not 'possible structural failure.' Findings get evidence, implications and cost context, never adjectives doing a lawyer's job.
02
We never repair what we inspect and never take referral fees from contractors or agents. The report has no revenue downstream of it — that's the whole point of it.
03
312 functional items is information the same way 15 findings are. You're buying a picture of the whole house, not a highlight reel of its problems.
04
Snow on the roof, a locked crawl space, a sealed attic hatch — every report ends with an access log. An inspection that hides its own limits isn't an inspection.
In the truck
Insured with general liability and errors-&-omissions coverage; certificates available before you book. OH Home Inspector License #HIS-2016-04127 (illustrative).
