What to Do If Your House Has Lead Paint: A Plain-Language Guide
If your house has lead paint, the next steps depend on the paint condition more than on the paint’s existence. Lead-based paint that is intact and well maintained behaves very differently from lead-based paint that is peeling, chipping, or chalking. This guide summarizes EPA and CDC guidance current as of 2026 — consult a certified professional for testing or abatement and your physician for symptom evaluation. The framework runs in three steps: assess the paint condition, confirm with testing where uncertainty remains, and choose a response that matches the actual risk profile of the house.

Step one: assess the paint condition
The single most important question is whether the paint in your house is intact or deteriorating. Intact lead-based paint, meaning paint that is bonded firmly to the substrate without cracking, peeling, chipping, or chalking, presents a much lower exposure pathway than deteriorating paint. The EPA’s Renovation, Repair, and Painting (RRP) Rule recognizes this distinction and structures its requirements around disturbing paint rather than around its mere presence.
Walk the house systematically. Check window sashes and stools, door frames, baseboards, stair risers, porch floors, and any exterior trim. Window components deserve special attention because friction surfaces (the rubbing contact between sash and stool, or between door and frame) shed paint dust even when the surface looks intact at a glance. Friction-surface lead-based paint is one of the most common exposure pathways in pre-1978 housing.
Step two: confirm with testing where uncertainty remains
If the house was built before 1978, assume the paint contains lead until tested. The federal ban on lead in residential paint took effect in 1978; older homes can have lead paint anywhere, often buried under newer paint layers. Testing confirms what is actually there and at what concentration.
Three testing options are available. An XRF (X-ray fluorescence) device used by a certified EPA Lead Inspector or Risk Assessor reads lead concentration in painted surfaces without destruction; this is the standard method for whole-house assessment. Paint-chip lab analysis sends a small physical sample to an accredited lab and produces a quantitative result; this is the most precise option for specific surfaces. EPA-recognized lead test swab kits provide a less precise but immediately readable result for homeowners doing initial screening. The full EPA lead-paint testing guidance describes when each method is appropriate.
Step three: response by paint condition
The response depends on the paint condition and on whether children under six or pregnant residents live in the house. Lead-based paint in intact, well-maintained condition, with no friction surfaces and no children under six in the home, can typically be monitored. Intact paint can be encapsulated or simply left in place under a maintenance schedule that catches deterioration early.
Deteriorating lead-based paint requires action. Peeling, chipping, chalking, or crumbling paint is shedding lead dust into the home. Lead dust is the most common exposure pathway in pre-1978 housing, especially for young children whose hand-to-mouth behavior brings dust into their bodies. The EPA’s guide to protecting your family from lead explains the dust-pathway risk in detail.
Containment and remediation options
Two broad responses exist for deteriorating lead-based paint: containment (encapsulation, interim controls, paint stabilization) and abatement (permanent removal or enclosure). Encapsulation uses a specialized coating that bonds with the existing paint and forms a continuous barrier; it is appropriate for intact surfaces that need ongoing protection but not full removal. Interim controls include wet-cleaning, friction-surface treatment, and dust-pathway management as a temporary risk-reduction approach.
Abatement is the permanent solution. Abatement methods include wet scraping, chemical stripping, heat-gun removal (at temperatures below the lead-vaporization threshold), enclosure with paneling or new substrate, and full removal of the painted component. Abatement must be performed by an EPA-certified abatement contractor working under approved work practices. The HUD guidance on lead hazard control describes abatement protocols.
If children under six live in the house
The decision framework changes if children under six or pregnant residents live in the house. Pediatric lead exposure is the highest-risk pathway because of developmental sensitivity. The CDC’s Childhood Lead Poisoning Prevention Program recommends blood-lead screening for children at ages 12 and 24 months when lead exposure is suspected. The current CDC blood-lead reference value is 3.5 micrograms per deciliter; any reading at or above this level triggers a public-health response.
Parents in pre-1978 housing should ask the child’s pediatrician about blood-lead screening even when no paint deterioration is visible. The screen is inexpensive (often covered by insurance), the result is immediately actionable, and elevated readings provide an early warning before clinical symptoms appear. The sibling article on pediatric lead test screening covers the screening process in detail.
Hiring a certified lead professional
Several certifications matter when hiring a lead professional. EPA-certified Lead Inspector identifies whether lead-based paint is present and at what concentration. EPA-certified Lead Risk Assessor identifies lead hazards (paint condition, dust, soil) and produces a written risk-assessment report with recommended response. EPA-certified RRP Renovator is required for any contractor disturbing more than six square feet of interior or twenty square feet of exterior painted surface in pre-1978 housing.
For abatement, an EPA-certified Lead Abatement Contractor is required. The four certifications are separate; a Renovator is not a Risk Assessor and a Risk Assessor is not an Abatement Contractor. The EPA certified-firm lookup tool allows homeowners to verify any contractor’s certification status before hiring.
Disclosure requirements when buying or selling
Federal law requires sellers and landlords of pre-1978 housing to disclose known lead-based paint and lead hazards. The federal disclosure form lists what the seller knows and what records are available. Buyers receive a ten-day window (or other period agreed in the contract) to commission lead testing before closing. The disclosure does not require the seller to test for lead; it only requires disclosure of what the seller already knows.
Buyers should treat the disclosure form as an inputted starting point rather than the final word. Even a clean disclosure does not mean the house is lead-free; it means the seller does not have records of lead. The buyer’s own testing under the inspection contingency is the practical confirmation. For broader context on the lead-paint landscape, the parent guide on asbestos and lead in pre-1978 housing walks through both hazards.
Day-to-day risk reduction
Several daily habits reduce lead exposure even before formal testing or remediation. Wet-clean floors and window sills weekly; lead dust binds to damp microfiber better than it does to dry cleaning. Wash children’s hands before meals and before bed. Use a HEPA-filter vacuum on carpets and upholstery; standard vacuums redistribute fine lead dust. Remove shoes at the door because exterior soil in pre-1978 neighborhoods can carry lead from historic deposition.
Replace stand-alone window air conditioners with units sealed at the frame, because the friction at the window opening generates lead dust during install and removal. Plant ground cover or mulch over bare soil within ten feet of the foundation of a pre-1978 home. These small habits do not replace formal remediation but reduce the dust pathway substantially.
When to consider abatement vs encapsulation
The choice between abatement and encapsulation typically turns on three factors: paint condition, planned occupancy duration, and budget. A family planning to stay in the home for fifteen years with school-age children may invest in full abatement of high-priority surfaces (window components, friction surfaces, kid-accessible trim). A buyer planning to flip within two years may use encapsulation plus interim controls as a lower-cost alternative.
Cost differences matter. Encapsulation in metro markets runs $1.50 to $4 per square foot. Component replacement (the most expensive abatement approach) runs $8 to $15 per square foot. Whole-house abatement of a 1,500 square foot pre-1978 home can run $20,000 to $50,000 depending on scope. The sibling article on lead paint abatement and EPA RRP protocols covers cost drivers in detail.
Front Range Colorado considerations
Pre-1978 housing is common in older Denver neighborhoods (Park Hill, Five Points, Wash Park, Berkeley) and historic Front Range towns (Boulder, Fort Collins, Pueblo, Trinidad). Colorado does not have a state lead-paint program separate from the federal EPA framework, but Front Range certified Lead Inspectors and Risk Assessors are widely available.
Local Colorado test pricing typically runs $300 to $600 for a residential lead inspection or risk assessment, depending on home size. Abatement pricing follows the national pattern. Buyers and homeowners in the Front Range can find certified professionals through the EPA’s national lookup tool.
Common lead-paint locations in pre-1978 homes
Lead-based paint shows up in predictable locations in pre-1978 housing. Window components are the highest-priority surfaces because of friction. Window sashes that slide up and down generate paint dust every time they move. Window stools (interior sills) collect that dust. Window troughs (the channel below the sash) hold deteriorating paint chips that can be reached by toddlers.
Door frames experience similar friction. Baseboards, especially in high-traffic areas, accumulate dust from repeated cleaning. Stair risers and treads in older homes often have lead-based paint that is wearing through. Built-in cabinets, especially kitchen cabinets that pre-date the 1978 ban, may have lead-based paint on interior surfaces that contact food packaging or dishes. Exterior surfaces, particularly historic painted siding, weathered trim, and porch flooring, contribute to soil contamination near the foundation drip line.
What lead exposure actually looks like in children
Lead exposure in young children rarely presents acute symptoms in the early stages. Most children with elevated blood lead show no obvious signs and are detected only through routine blood-lead screening. As exposure increases, symptoms can include irritability, difficulty concentrating, slowed development, fatigue, abdominal pain, and reduced appetite. At higher exposure levels, more severe symptoms appear.
The asymptomatic nature of early-stage lead exposure is exactly why screening matters. A child with mildly elevated blood lead (in the 3.5 to 10 microgram per deciliter range) typically looks and behaves normally, but the cumulative effect of even mild ongoing exposure during developmental years is consequential. The CDC’s recommendation of routine blood-lead screening for children in pre-1978 housing is built around this asymptomatic reality.
What changes after a positive lead finding in your home
The discovery that your house has lead paint changes the maintenance calendar but does not usually change daily life. Households that learn their home has lead-based paint typically continue normal occupancy with adjusted habits and a clearer maintenance schedule. The biggest practical change is awareness during routine projects: planning to repaint a window frame, swap out a baseboard, or sand a door now involves a conversation about whether the work disturbs lead-based paint.
Some homeowners experience a brief period of heightened concern after the positive test result, followed by stabilization once the response plan is clear. The pattern is normal: a positive test result is consequential information, but the response framework is well-established and the daily-habit risk reduction is straightforward. Long-term residents in pre-1978 housing typically live with the knowledge that their home contains lead-based paint and apply the appropriate maintenance practices without ongoing anxiety.
