Pre-1978 Home Renovation: Asbestos and Lead Paint Together

TL;DR: Homes built before 1978, when lead-based residential paint was banned, frequently contain both lead paint and asbestos-containing materials, since asbestos use in building products continued for several more years afterward. Testing for both hazards before any demolition or flooring work begins is the responsible first step, since undisturbed materials generally pose little risk, while cutting, sanding, or demolishing through them releases hazardous dust and fibers that can contaminate a home well beyond the immediate work area.

Key Takeaways

• Lead-based paint was banned for residential use in 1978, meaning any home built before that year should be assumed to have it somewhere unless testing confirms otherwise.

  
  

• Asbestos was used in thousands of building materials, including insulation, floor tile, ceiling tile, plaster, and drywall compound, and its use was not fully phased out until several years after the 1978 lead paint ban.

  
  

• Both hazards are generally low-risk when undisturbed but become dangerous the moment they are sanded, cut, chipped, or demolished, releasing lead dust or asbestos fibers into the air.

  
  

• Improper demolition in an older home can spread lead dust or asbestos fibers through HVAC systems to parts of the home never directly touched by the renovation itself.

  
  

• Testing for both hazards before demolition begins, rather than discovering them mid-project, is the standard practice that protects the household and avoids costly mid-project stops.

  
  

Renovating a home built before 1978 in Central Oregon carries two hazard considerations that newer construction generally does not: lead-based paint and asbestos-containing materials. These substances share a similar risk profile, generally safe when left undisturbed, genuinely hazardous once demolition or renovation work disturbs them, and homes built before this era frequently contain both simultaneously rather than just one or the other.

DustFree PNW's interior demolition service handles older home projects across Central Oregon with the testing recommendations this era of construction requires. Here is what to know about both hazards before starting a renovation.

Where Each Hazard Is Commonly Found

Hazard	Common Locations	Era of Concern
Lead-based paint	Interior and exterior painted surfaces, trim, doors, windows	Any home built before 1978
Asbestos in flooring	Vinyl floor tile (especially 9-by-9 inch tiles) and adhesive backing	Common through the 1970s and into the early 1980s
Asbestos in insulation	Pipe wrap, duct insulation, some attic and wall insulation	Common through the 1970s
Asbestos in wall materials	Plaster, drywall joint compound, some textured ceiling finishes	Common through the 1970s and into the early 1980s
Asbestos in ceiling materials	Ceiling tiles, popcorn or textured ceiling finishes	Common through the 1970s and into the early 1980s

Notably, asbestos use in building materials continued for several years after the 1978 lead paint ban, since it took time for manufacturers to phase out asbestos-containing products across the many applications where it had been used. This means a home from the mid-to-late 1970s or even the early 1980s can still carry asbestos risk even though the lead paint concern is tied specifically to the 1978 cutoff.

Why Undisturbed Materials Are Generally Low Risk

Both lead paint and asbestos-containing materials share an important characteristic: when left intact and undisturbed, they generally pose minimal ongoing risk. Lead paint in good condition, not peeling, chipping, or deteriorating, does not typically release significant lead dust into a home's environment. Asbestos-containing materials that remain bonded and undamaged similarly do not release fibers into the air under normal conditions.

The risk profile changes entirely the moment renovation work disturbs these materials. Sanding walls, chipping paint, cutting into plaster, or demolishing flooring all have the potential to release hazardous lead dust or asbestos fibers, and this is precisely the point at which testing before work begins becomes essential rather than optional.

Why Testing for Pre-1978 Home Renovation Asbestos and Lead Paint Matters Before Any Demolition

Testing for lead and asbestos before renovation begins is recommended, and in many cases legally required, specifically because disturbing either material without proper handling creates health risks that extend beyond the immediate work area. Both lead dust and asbestos fibers can travel through a home's HVAC system and settle on surfaces in rooms never directly touched by the renovation itself, meaning a contained kitchen project can end up contaminating bedrooms or living spaces elsewhere in the home if the hazard was not identified and managed correctly from the start.

Children and pregnant women face particularly serious risks from lead exposure specifically, including documented links to neurological damage, behavioral disorders, and developmental delays, which is part of why testing before disturbing any painted surface in a pre-1978 home is treated as a genuine health priority rather than a bureaucratic formality.

What Happens If Testing Confirms a Hazard Is Present

If testing confirms asbestos-containing materials are present, licensed asbestos abatement professionals handle the removal following strict containment, removal, and disposal procedures, sometimes with clearance testing afterward to confirm the area is safe to proceed. If lead paint is confirmed, similarly certified professionals follow required dust control and safe work practices during any disturbance of the affected surfaces, consistent with federal Renovation, Repair, and Painting rule requirements and any applicable state regulations.

In either case, the testing result determines the correct path forward before any demolition proceeds, rather than the renovation crew discovering a suspect material mid-project and having to pause work to address it after the fact.

What a Properly Tested and Handled Renovation Looks Like

A properly handled pre-1978 renovation begins with testing for both lead paint and asbestos in the materials the project scope will disturb, proceeds with appropriate abatement or safe work practices if either hazard is confirmed present, and delivers a demolition or renovation outcome where the household's air and surfaces have not been contaminated by either substance during the process.

DustFree PNW works with older Central Oregon homes and recommends testing for both hazards before demolition begins on any project involving flooring, plaster, or painted surfaces in structures from this era.

Final Thoughts

Renovating a pre-1978 home means planning for both lead paint and asbestos as a combined consideration, not just one or the other. Testing before demolition begins, understanding that undisturbed materials are generally low risk, and following through with proper abatement when either hazard is confirmed are the steps that protect a household throughout a renovation project.

FAQ

Do all homes built before 1978 have lead paint?

It should be assumed present unless testing confirms otherwise, since lead-based residential paint was banned in 1978 and was commonly used on interior and exterior surfaces before that year.

Can a home have both asbestos and lead paint?

Yes, frequently. Asbestos use in building materials continued for several years after the 1978 lead paint ban, so homes from this era commonly carry both hazards simultaneously.

Is undisturbed lead paint or asbestos dangerous?

Generally not, when the materials remain intact and undamaged. The risk increases significantly once renovation work sands, cuts, chips, or demolishes through the affected materials.

Where is asbestos commonly found in older flooring?

Vinyl floor tile, particularly older 9-by-9 inch tiles, and the adhesive backing beneath them are among the most common sources of asbestos in older residential flooring.

What happens if testing confirms asbestos or lead paint is present?

Licensed asbestos abatement professionals or certified lead-safe renovators handle the affected materials following required containment, removal, and disposal procedures before the rest of the renovation proceeds.

Does DustFree PNW work with older Central Oregon homes?

Yes. DustFree PNW handles demolition and flooring removal in older homes across Central Oregon and recommends testing for asbestos and lead paint before any work begins in pre-1978 structures. Contact us for a free quote.
