EXPOSED
Nearly all of the work — crawling attics and crawlspaces, fitting batts around wiring and pipes, spraying foam into irregular stud bays, taping vapor barriers — happens in cramped, non-standard spaces that today's robotics cannot navigate, so AI touches almost none of the hands-on hours. What AI does absorb is the office layer around the job: takeoffs from plans, R-value and energy-code calculations, material bidding, and scheduling. The vulnerability is not automation of the installer but commoditization: no license is required, the decisions are mostly procedural, and pricing pressure plus prefabricated and panelized envelope systems can thin crew hours per house.
Dipped in 2020, then grew past where it started.
Median pay $40,380 → $49,120 -2.7% in real terms
This line is counted by the Bureau of Labor Statistics — the one figure on this page that isn't a judgement of ours. Headcount moves on demand, offshoring, demographics and the business cycle, and automation is one term among several, often not the loudest.
So a falling line is not evidence that AI did it, and a rising one is not evidence that it won't. Both happen in this register: some occupations resist automation and shrink anyway, others are highly automatable and keep growing. The marked year is 2020.
BLS projection, 2024–2034
+3.8% 40,200 → 41,700 on the projections basis
Growing, and only partly exposed
The BLS expects +3.8% more of these jobs by 2034, and at 59/100 the work is only partly exposed — some tasks are automatable, the core of the job is not. Nothing here is in tension.
Different clocks. The score is what current AI could do to this work today. The projection is how many of these jobs will exist in 2034. Everything between the two — how fast employers actually adopt, whether demand grows in the meantime — is why they can point opposite ways without either being wrong.
~3,400 openings a year on average, including replacing people who leave.

Holding it up: embodiment . Weakest point: liability shield .
Tasks largely resist digitisation Cutting batts to fit around a junction box, blocking, and a rats-nest of romex in a 22-inch joist bay — then belly-crawling to the eave to do it again — is work no machine on the market performs, and the only tasks a model can take are the plan takeoff and the material order, which is why this sits at 18 rather than a mixed score.
Hands-on in uncontrolled environments The job is done in 130-degree attics, on knees in crawlspaces with 30 inches of headroom, on ladders and stilts against ceilings, wearing a respirator against fiberglass and isocyanates — uncontrolled, unlit, unconditioned spaces that put this at the top of the physical band, held off 20 only because some work happens in open new-construction framing before drywall.
Certification preferred, not legally required No state licenses a floor/ceiling/wall insulator; the general contractor pulls the permit and the code inspector signs off on the insulation, and the 5 reflects only the real credentials that do exist — OSHA 10/30, respirator fit testing, and SPF applicator training required by foam manufacturers for warranty — none of which the law makes you personally answerable under.
Meaningful discretion Real calls exist — where to leave clearance around recessed cans and flues, when a cathedral ceiling needs baffles for ventilation, whether a substrate is too damp for closed-cell foam — but R-value, depth, and vapor-barrier placement are specified by IECC and the plans, so the discretion is troubleshooting inside a spec rather than owning the spec, which lands it at 8.
The verdict above describes this occupation as a whole. Almost nobody does the typical version of a job — tick what's actually in your week and see how your own mix sits.
Your task mix speaks to task resistance (18/20 here) — how much of the day's work current AI already does. That is the dimension the boxes above are about.
It cannot move the other three. Liability shield (5/20) is whether the law requires a licensed human to sign. Trust premium (9/20) is whether buyers specifically pay for a person. Judgment and accountability (8/20) is whether the role exists to own consequential calls. Those are facts about the occupation's standing, not about which tasks are in your week — a paralegal who does only trial exhibits still holds no licence. Together they are 22 of this occupation's 59 points (37%).
Embodiment (19/20) is also a property of the work rather than the worker, but we don't tag individual tasks as physical or not, so the picker can't tell you anything about it. That's a limit of this tool, not a claim.
Did we get the list right? Tell us what's missing — the tasks are written from the outside, and you're reading this from the inside.
The moves above are yours to make. This is the other half: what would have to change in the world for the occupation itself to score higher. None of it is in any one person's gift, but it is where the floor actually comes from. Scores here are not a one-way ratchet. Only two of the five dimensions — task resistance and embodiment — track what machines can do. The other three track law, what buyers will pay for, and who is answerable, and those move in both directions, often in response to the same pressure AI creates. If every lever below landed, this occupation would score around 78/100 — SAFE.
Growth of performance-guaranteed retrofit contracting — utility and IRA/HOMES-rebate programs that pay on measured energy savings rather than square footage, plus Passive House and Pearl-certification work where the buyer selects a named crew with an air-tightness track record. Buyers paying for a specific installer's blower-door numbers is a real premium, distinct from commodity batt pricing.
Insurer-driven route: builder's-risk and E&O carriers requiring documented Grade I installation (RESNET Chapter 3 grading) by a certified installer before covering moisture/mold claims traced to envelope defects — already a live condition in some HERS-rated and Passive House projects.
State adoption of blower-door/air-leakage verification tiers (IECC 2021 §R402.4.1.2) that require a named, credentialed installer-of-record to sign the insulation installation certificate, plus spray-foam-specific licensing on the model of Massachusetts' SPF applicator rules and EPA's proposed diisocyanate worker-certification framework under TSCA. If an individual crew member's credential number must appear on a certificate the code official accepts, and reinspection liability attaches to that name, this moves materially.
Task-mix shift toward diagnostic retrofit: if panelized/prefab envelopes absorb the routine new-construction batt tier, the surviving work is existing-building air sealing where the installer decides sequencing around knob-and-tube wiring, recessed cans, unvented roof assemblies, and vapor-drive direction — calls where being wrong causes condensation and mold. Watch for the retrofit share of insulation employment rising relative to new-build.
Formal designation of a moisture/vapor-control responsibility in code commentary or in ASTM/ABAA standards making the installing contractor — not the designer — accountable for assembly drying capacity in unvented roofs and interior retrofit of masonry walls.
The limit. task_resistance (18) and embodiment (19) are already near maximum and have no headroom; the whole realistic movement is institutional. Even fully realized, licensing for insulation is fragmented state-by-state and historically weak — spray foam is the only sub-trade with credible momentum, so a large share of batt and blown-in work likely stays unlicensed and commodity-priced regardless.

We have no reported case of a named organisation automating this occupation. Not one deployment, not one announcement.
That is worth saying out loud next to a score of 59. The verdict above is about what the work exposes — what current AI could do to these tasks. It is not a claim that anyone has done it. For this occupation those two things have come apart completely: the capability argument is on this page, and the evidence column is empty.
