Mold Remediation in Gettysburg, a local provider of mold remediation in Gettysburg, PA, released new local data and a winter checklist. 87% of Gettysburg homes were built before 1980, and almost half before 1940.

Gettysburg, PA – November 12, 2026 – Mold Remediation in Gettysburg, a local provider of mold remediation in Gettysburg, PA, is asking borough and Adams County homeowners to check basements, crawlspaces and exterior walls as the heating season starts, after pulling local housing and flood data that shows how much of Gettysburg’s housing is at risk.

What the local numbers show

U.S. Census Bureau data (American Community Survey, 2020 to 2024) puts the median year built for Gettysburg’s 2,801 homes at 1942, compared with 1980 for Adams County as a whole. 47.5% of homes in the borough were built before 1940 and 87.2% before 1980. In the county overall, those figures are 17.5% and 49.5%.

FEMA’s National Flood Insurance Program has paid 82 claims in ZIP code 17325 since 1978, totaling about $2.64 million. The biggest years were 1996, the January snowmelt flood, with 28 claims, and 2011 with 25. Adams County as a whole has 399 claims on record. Only insured properties appear in that data, so the real number of homes that have taken on water is higher.

“Most of the houses we see in town sit on fieldstone or rubble foundations with no vapor barrier,” said Josh “Mold Man” Jacobs, owner of Mold Remediation in Gettysburg. “Water moves through the stone slowly and spreads behind plaster and finished walls. By the time someone smells it, the mold is usually bigger than it looks.”

Why winter matters

When the heat comes on, warm indoor air meets cold stone, cold exterior walls and cold attic sheathing. That condensation feeds mold in places that stayed dry all summer. The EPA advises drying wet materials within 24 to 48 hours and keeping indoor humidity below 60%, ideally 30 to 50% (see EPA guidance).

A winter checklist for Gettysburg homeowners

• Check fieldstone basement walls, sill plates and floor joists for damp spots, white mineral crust or a musty smell.

• Put a $15 hygrometer in the basement. Readings above 60% mean a dehumidifier or a ventilation fix.

• Look at attic sheathing and the underside of the roof deck for dark staining near vents and chimneys.

• Check that gutters and downspouts carry water away from the foundation before the first freeze.

• Watch window sills and exterior corners of closets, where condensation collects first.

• Under the EPA’s 10-square-foot guideline, a small patch on a hard surface is often a homeowner job once the moisture is fixed. Larger areas, mold inside walls or ductwork, or mold after a flood call for a professional.

What it costs

Most mold remediation jobs in Gettysburg run $1,125 to $3,750, or about $10 to $25 per square foot of affected area. A bathroom typically runs $500 to $1,500, a basement wall or finished room about $2,400, and a crawlspace about $3,500. Jobs that reach framing, subfloor or ductwork start around $10,000. Testing adds $300 to $1,000. The full breakdown by job type and size is in the company’s Gettysburg mold remediation cost guide.

Pennsylvania has no state license for mold remediation, so the company recommends homeowners ask any contractor for a Pennsylvania Home Improvement Contractor registration number, a written scope that names the water source, and independent clearance testing after the work.
