Houston Infrastructure Age
With 69% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.

Housing Age Profile
Viewed through the lens of construction era, Houston is predominantly an older city — a median build year of 1974 puts most of the residential inventory in the range where pre-1986 plumbing materials were the standard.
Over half of homes in Houston were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

How Remediation Costs Compare in Houston
Given current Houston property values, the remediation share falls in the moderate tier — an indicator that the household financial perspective here calls for advance planning rather than dismissal, with most homeowners positioned to address documented issues through deliberate budgeting rather than needing to treat remediation as a significant equity event or financial emergency.
Remediation costs are moderate relative to home values in Houston. The estimated $1,200–$3,300 range is manageable for most homeowners but still worth budgeting for. Home values are 34% below the Missouri average.
Houston: Lead Risk & Vulnerable Populations
Why children are most at risk: The CDC states there is no safe level of lead exposure for children. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
Pulling a tap sample fills the gap that utility data cannot close, particularly here where 69% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Houston.

Houston: Flood History & Water Damage Risk
FEMA data shows 100% of Houston's ZIP codes mapped into designated flood zones, paired with an NFIP record of 7 claims. That footprint places local flood exposure in the range where it warrants attention without rising to high-severity planning territory.
Houston has a moderate flood history with 7 FEMA claims averaging $40,632 per payout. 100% of ZIP codes fall within FEMA flood zones. Flood events can contaminate drinking water and overwhelm treatment systems.
How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies. Even after floodwaters recede, contamination can persist in wells and aging infrastructure. Flood damage can add significantly to the estimated <strong>$2,200</strong> remediation cost per household.
Residents in flood-prone areas should consider flood insurance even outside FEMA zones — over 25% of flood claims come from low-to-moderate risk areas. After any flood event, test your water before drinking.
