Key Risks for 1990s Homes
- Late-period polybutylene (pre-1995)
- Chinese drywall (2001–2009 overlap)
- EIFS moisture intrusion
- Original HVAC & roof nearing end of life
- Formaldehyde off-gassing from composite wood
1990s construction avoided the classic hazards but introduced new ones: polybutylene piping (until ~1995), early synthetic stucco systems prone to moisture intrusion, and composite wood products that off-gas formaldehyde. HVAC systems installed in the 1990s are now 25–35 years old and approaching replacement.
What to Inspect
Verify plumbing material and check for signs of EIFS moisture damage at windows and penetrations. Budget for HVAC replacement within 5–10 years.
