Housing Age Profile

Development in Dumfries unfolded across multiple decades, and the median build year of 1986 reflects a housing inventory where eras of construction are genuinely mixed - including portions that predate the federal prohibition on lead solder in plumbing.

1986

Median Year Built

31%

Pre-1986 (Lead Paint Risk)

2%

Pre-1970 (Lead Pipes Risk)

Pre-1970 (2%) 1970–1986 (29%) Post-1986 (69%)

Most homes in Dumfries were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Dumfries: Remediation Cost in Perspective

How much of a Dumfries home's value does documented remediation represent? A small fraction - the equity share here is in the low tier, and from a household financial perspective, most property owners are considering a commitment that fits comfortably within standard planning rather than a decision that rises to the level of a material budget event or significant equity consideration.

Median Home Value

$497,700

Est. Remediation

$2,200

Remediation as % of home value 0.4%

Remediation costs in Dumfries are relatively low compared to home values. The $1,200–$3,400 estimated range is a small fraction of median property value. Home values are 59% above the Virginia average.

Protecting Children from Lead in Dumfries

31%

Homes Built Before 1986

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.

Wherever 31% of local housing was built before solder rules changed - as is the case in Dumfries - a faucet-level sample closes the gap that aggregate utility data cannot.

Historical Flood-Claim Evidence for Dumfries

Total FEMA Flood Claims

Avg Reported Sum With Payment Data

0%

A/V Share of Claim-Record ZIPs

Historical NFIP data for Dumfries contains 34 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $7,095. Among ZIP codes with claim records, 0% have an A- or V-family dominant rated zone recorded in those historical claims. This is not a complete current FEMA property-map inventory.

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. The <strong>$2,200</strong> remediation estimate shown here excludes flood insurance and is not derived from NFIP claim count.

Claim count does not establish current property risk. Check the exact address in FEMA's current map and obtain a property-specific insurance quote when relevant.
