What to Do If Lead Paint in House: Action Steps 2026
“What to do if lead paint in house” is the question that follows a positive XRF reading, a confirmed paint-chip lab result, or just the discovery that your home was built before 1978. The honest answer depends on the paint’s condition. Intact lead paint is a different problem from deteriorated lead paint, and both are different from a child with elevated blood lead. This guide walks through the action sequence in priority order, with the federal regulatory context and the practical cost ranges Front Range Colorado homeowners face in 2026. Health-adjacent guidance summarizes EPA, HUD, and CDC sources — pediatric concerns belong with a physician.

What to do if lead paint in house: the priority sequence
Lead-based paint is only a hazard when fibers, chips, or dust become available for ingestion or inhalation. Intact paint that nobody touches is generally not a hazard. Deteriorated paint within reach of children is. The action sequence ranks responses by the urgency of the situation:
- Confirm the finding via certified testing
- If a child under six lives in or regularly visits the home, talk to the pediatrician about blood-lead screening
- For intact paint, implement management practices and avoid disturbance
- For deteriorated paint, encapsulate or remove using EPA-RRP-certified work practices
- For confirmed lead-paint hazards on rental property, comply with the federal disclosure rule and state-level remediation requirements
This sequence respects the actual risk profile. Tearing into intact paint to “do something” can create the very hazard the homeowner was trying to avoid.
Step 1: Confirm the finding via certified testing
The first action after suspicion or initial swab-test indication is professional confirmation. Consumer paint-test swabs (NaS-based color-change kits) are screening tools, not regulatory-quality tests. They can produce false negatives on dark or oil-based paint and false positives on certain compounds. The federal framework recognizes two acceptable confirmation methods:
XRF analyzer testing
An EPA-certified Lead-Based Paint Inspector or Risk Assessor uses a portable X-ray fluorescence (XRF) instrument to measure lead concentration in mg/cm² without damaging the painted surface. The federal threshold for lead-based paint is 1.0 mg/cm² or higher. The component-by-component inspection process is covered in detail in the lead paint inspection near me guide.
Paint-chip lab analysis
A small paint chip is collected and sent to a NLLAP-recognized laboratory for analysis by polarized light microscopy and atomic absorption spectroscopy. Result is reported in weight percent or ppm. Lab analysis is the more accurate method for ambiguous XRF readings or for legally contested findings.
A homeowner unsure whether confirmed lead is present should hire an EPA-certified inspector before any disturbance. Confirmation drives every subsequent action.
Step 2: For pre-1978 homes with children under six, talk to the pediatrician
Blood-lead screening is a clinical decision belonging to the child’s pediatrician. The parent’s role is to bring household-side data to the visit: home year of construction, paint condition, recent renovation, water-test results, and any occupational exposure of household adults. The pediatrician decides whether and when to order screening. The clinical framework is covered in the lead poisoning screening guide.
Do not delay this conversation pending household remediation. Children’s developing brains are sensitive to lead, and screening identifies whether action beyond environmental remediation is needed.
Step 3: For intact paint, implement management practices
Intact, undamaged lead-based paint on surfaces that are not subject to friction or impact can often be managed in place — this is the federal “interim controls” approach. Practical management:
Visual inspection on a schedule
Walk every painted component in the home quarterly. Look for chipping, peeling, chalking, alligatoring, or chip accumulation on horizontal surfaces below painted components. Photograph baseline condition so future changes are visible.
Friction-and-impact surface attention
Window sashes, door jambs, stair treads, and floor-level baseboards are friction-and-impact surfaces — the paint there abrades during normal use even when “intact.” These surfaces deserve closer monitoring or proactive encapsulation.
Wet-cleaning routine
HEPA-vacuum and wet-wipe horizontal surfaces (windowsills, baseboards, floors) weekly in homes with children under six. Standard household cleaning leaves lead dust behind; wet methods capture it. EPA’s “Protect Your Family from Lead in Your Home” pamphlet provides the cleaning protocol.
Behavior management for young children
Children should not chew on painted surfaces, eat with hands not freshly washed, or play in soil within 10 feet of pre-1978 painted exteriors. These behaviors are the actual exposure pathway — managing them is part of lead-safe operations.
No DIY sanding, scraping, or dry-removing
The most preventable lead-exposure events come from well-meaning DIY paint removal. Sanding pre-1978 paint generates fine lead dust that travels throughout the home, settles in HVAC ducts, and contaminates surfaces that were previously clean. Even removing a single windowsill with a power sander can produce measurable lead-dust exposure across an entire floor.
Step 4: For deteriorated paint, encapsulate or remediate
Once paint is peeling, chipping, alligatoring, or chalking, the management approach has failed and remediation is required. The federal framework recognizes three remediation strategies, with cost and durability tradeoffs:
Encapsulation
A specialty coating bonds to and seals the existing lead-based paint, preventing chip release and providing a wear-resistant overlay. Encapsulants must be tested for compatibility with the substrate and the existing paint. Front Range encapsulation typically runs $4–8 per square foot for the coating system plus surface preparation. Suitable for components with intact-but-aging paint where future renovation is not planned in the near term.
Enclosure
A solid covering (drywall over plaster, vinyl-clad windows over wood, new flooring over old) physically isolates the lead-based paint from the occupied space. The original lead paint remains in the structure but is no longer accessible. Enclosure can be very cost-effective when combined with cosmetic renovation but does not remove the future-disturbance question — anyone working on the home later must treat the underlying material as lead.
Component replacement or removal
Complete removal of the lead-bearing component (window sashes replaced, baseboards removed, painted plaster demolished) eliminates the lead-paint source. Cost is higher upfront but removes the hazard permanently. Front Range component replacement runs $400–1,000 per major component (window assembly, door jamb set, painted-trim ensemble).
Step 5: Hire EPA-RRP-certified contractors for any disturbance
The federal Renovation, Repair, and Painting (RRP) Rule (40 CFR Part 745, Subpart E) requires that any compensated renovation in pre-1978 housing that disturbs more than six interior or 20 exterior square feet of painted surface be performed by an EPA-certified Lead-Safe Renovator firm using lead-safe work practices. RRP-certified firms must:
- Contain the work area with plastic sheeting
- Prohibit prohibited work practices (no power-tool sanding without HEPA-shroud attachment, no torch burning, no heat-stripping above 1100°F)
- Use wet methods to suppress dust
- HEPA-vacuum at completion
- Verify cleanup with white-glove inspection or post-work dust-wipe testing
- Document the work and provide records to the homeowner
Homeowner DIY in their own home is generally exempt from RRP, but the same work practices are strongly recommended for safety. DIY lead-paint disturbance without RRP-equivalent practices is the most common cause of post-renovation elevated blood-lead readings in young children.
Cost ranges Front Range homeowners actually see
Encapsulation of a single bedroom — $1,800–3,500
Surface preparation, primer, two coats of encapsulant, and refinish on the encapsulated surface. Suitable for intact-but-aging window-area paint.
Window component replacement — $600–1,200 per window
Removal of pre-1978 wood window with leaded glazing or interior trim, RRP-certified work practices, and replacement with new vinyl, fiberglass, or wood window. Most expensive but most permanent.
Full-home interim controls — $4,000–9,000
Visual baseline documentation, deteriorated-paint stabilization, friction-surface encapsulation, exterior trim repair, and a written operations-and-maintenance plan.
Whole-home abatement — $15,000–40,000+
Comprehensive removal or enclosure of all identified lead-based paint with post-abatement clearance testing. Front Range pricing depends heavily on home size, component count, and reconstruction scope.
Rental property: additional obligations
Landlords of pre-1978 rental property carry obligations beyond what owner-occupants face. The federal disclosure rule — detailed in the federal lead based paint disclosure guide — requires written disclosure of known lead-based paint and hazards at every lease and renewal. HUD-funded housing carries additional Lead Safe Housing Rule requirements (24 CFR Part 35) governing risk assessment, hazard control, and interim controls.
Tenants notifying landlords of deteriorated lead paint create a documented complaint; the federal civil right of action under Section 1018 of Title X applies to landlord noncompliance with disclosure and remediation duties.
Soil and dust: the parallel exposure paths
Lead-based paint chips and dust accumulate in soil within 10 feet of pre-1978 painted exteriors. Children playing in that soil can ingest contaminated dirt. EPA hazard standards: bare soil play areas at 400 ppm or higher, bare soil yard areas at 1,200 ppm or higher. Remediation: cover bare soil with grass, mulch, or paving; for elevated levels, soil removal and replacement.
Interior lead dust accumulates on horizontal surfaces from window troughs (the heaviest concentration source), painted door frames, and high-friction surfaces. EPA hazard standards as of 2019: 10 µg/ft² on floors, 100 µg/ft² on interior windowsills. Wet cleaning and HEPA-vacuum routines control household dust. The broader hazard framework lives on the asbestos and lead pillar.
What not to do
Do not sand pre-1978 paint without proper HEPA-vacuum attachment. Do not use heat guns above 1100°F or open-flame torches on pre-1978 paint. Do not use power-washers on exterior pre-1978 paint — power-washing spreads paint chips and contaminates surrounding soil. Do not paint over deteriorated paint without first stabilizing it — paint will not bond to chalking or peeling surfaces.
Do not let a tenant or contractor sand pre-1978 paint without RRP certification and proper containment. Do not assume that an interior paint job that looked fine for fifteen years is still fine — friction and weathering produce gradual deterioration that becomes a hazard before it becomes obvious.
How tenant and landlord responsibilities differ
The action sequence above applies to owner-occupants. Tenants in pre-1978 rental property have different practical options and different legal levers. Tenants generally cannot undertake remediation themselves; the landlord controls structural and surface modifications. What tenants can do: notify the landlord in writing of any deteriorated paint, document the condition with dated photographs, ensure the federal lead-paint disclosure was provided at lease signing, and arrange pediatric blood-lead screening for any young children in the home.
If a tenant’s child develops elevated blood lead and the landlord failed to disclose known lead-paint hazards, the federal civil right of action under Section 1018 of Title X provides recovery for actual damages, treble damages, and attorney’s fees. Tenants in this position should preserve all written communications and consult an attorney before negotiating with the landlord. State landlord-tenant law layers additional protections in many jurisdictions; Colorado’s habitability standards may apply alongside the federal framework.
Documentation that protects future value
Homeowners who invest in remediation should also invest in documentation. The records that matter for both peace of mind and future resale: the original inspection or risk-assessment report from an EPA-certified Inspector or Risk Assessor; the work orders, scope sheets, and EPA RRP-renovator documentation from any remediation contractor; post-remediation clearance-test results if the work warranted them; and photographs of the surfaces before and after remediation.
When the homeowner eventually sells the property, these records become disclosable items under the federal Lead Disclosure Rule. Well-documented remediation supports the seller’s position at closing — the buyer can see exactly what was identified, what was done, and what verification followed. The Title X disclosure obligations are covered in more detail in the federal disclosure form guide.
When to call a professional
For confirmation testing, hire an EPA-certified Inspector or Risk Assessor. For remediation, hire an EPA-RRP-certified Renovator firm or, for full abatement, an EPA-certified Lead Abatement firm. For pediatric blood-lead concerns, talk to your child’s pediatrician. Front Range homeowners can layer these professionals into a coordinated response within a typical timeline of 4–8 weeks for a non-emergency renovation plan.
