Lead Paint Removal Without the 3–10x Scoping Mistake

RRP vs. Full Abatement — Which One Are You Buying?

This is the intake question that matters more than the bid. Federal lead rules split into two programs that get confused constantly, and the confusion is expensive in both directions: owners over-scope to full abatement when RRP satisfies the legal obligation, or they buy RRP-level work when a lender, housing agency, or risk assessment actually demands hazard elimination with clearance.

The cost differential between the two is 3–10x on the same building. So before we price anything, we ask the question that sorts every lead project: are you eliminating a hazard, or are you renovating in a way that happens to disturb paint? Get that answer wrong and you either pay abatement prices for a renovation, or fail clearance on work that was never designed to pass it.

Real buildings are rarely pure cases. A renovation can trigger RRP on most of the floor plate while a housing-agency finding demands true abatement in two units; an industrial repaint can sit entirely outside the residential rules and still carry the heaviest worker-exposure burden on the site. iSi scopes to the actual mix — and prices each pathway for what it is instead of billing the whole job at the abatement rate.

How iSi Runs a Lead Project

Lead work fails at the edges — the intake that never asked what the project is legally required to accomplish, the containment that leaked dust into occupied space, the cleanup that failed its wipes twice. So the sequence is deliberate:

Lead Removal Questions Owners Actually Ask

Who has to be RRP certified?

Any firm performing renovation that disturbs lead paint in pre-1978 target housing above de minimis thresholds must hold EPA-certified firm status under 40 CFR Part 745 Subpart E, with trained renovators running the work practices. iSi holds that certification. In the Kansas, Missouri, Oklahoma, and Texas markets we serve, RRP requires the EPA firm certification with no additional state lead license on top of it — which simplifies contracting, but doesn't simplify the work: the containment, dust control, and cleaning verification still have to be done right.

What is clearance testing?

Clearance is the exit exam for abatement. After hazard-elimination work under Subpart L, dust-wipe samples are collected from floors and sills and analyzed against clearance standards; the space is not released for re-occupancy until it passes. RRP projects use post-renovation cleaning verification instead. This is one of the concrete differences between the programs — and a reason a building owner who needs "documentation that the hazard is gone" is buying abatement, not RRP.

Why does lead dust cleanup fail?

Because dry sweeping and shop vacs redistribute lead dust instead of removing it. Passing dust-wipe numbers comes from HEPA vacuuming, wet cleaning, and a deliberate top-down sequence — then sampling to prove it. When we take over a failed cleanup, the problem is almost never effort. It's method and sequence.

What about the workers doing the removal?

Worker protection runs in parallel with the building-side rules. OSHA's construction lead standard, 29 CFR 1926.62, sets a permissible exposure limit of 50 µg/m³ (8-hour TWA) and requires exposure assessment, respiratory protection, hygiene facilities, and biological monitoring where triggered. A contractor who can't show you their 1926.62 compliance program is telling you how the rest of the job will be run.

Why combine lead, asbestos, and demolition under one contract?

Because a pre-1978 building headed for renovation or demolition usually has both regulated paints and asbestos-containing materials, and staging three contractors around each other multiplies mobilizations, containment builds, and schedule risk. iSi prices the combined scope — asbestos, lead, and demolition — as one fixed bid with one containment and mobilization sequence. It's the same crew logic behind our broader industrial services line: one team from assessment through closeout.
