In the CSIA hierarchy, each level exists because the one below it hit a wall. A Level 1 sees accessible areas; a Level 2 adds the camera and concealed-space review. A Level 3 begins where both stop: when the evidence says something serious is happening inside the structure, and the only way to confirm is to open it.
Findings that legitimately escalate to Level 3
What “invasive” actually means
Targeted, not destructive. A section of drywall, a course of bricks, a chase panel, opened where the evidence points, examined, then properly restored as part of the scope. The restoration is quoted up front with everything else; you’re never left with an open wall and a shrug.
What happens after
Level 3 findings usually resolve into one of three paths: targeted repair, partial rebuild, or, more often than you’d think, confirmation that the suspected hazard isn’t there, which is worth every penny to know before winter. Whichever way it goes, you get the full documented file and fixed pricing for any recommended work, per our standard process.
