Huntington Township is rural northern Adams County, around Idaville and the York Springs area, with U.S. Route 15 running through it. None of the homes here are attached, and most are owned by the people living in them. North on U.S. Route 15, about 20 to 25 minutes from our office.
About 17% of homes were built before 1940, close to the county average, and nearly 3 in 10 date from before 1960. Those older houses are mostly farmhouses with stone or block cellars, many with kitchens, baths, or porches added on over the years.
The median home was built in 1983, so the other half of the township is newer country houses on their own lots, with block or poured basements and crawl spaces under additions. With no attached homes at all, moisture problems start with the house itself, not with a neighbor.
Quick answer
Huntington Township has about 960 homes, and 42.2% were built before 1980 (49.5% across Adams County). FEMA records 7 flood insurance claims in ZIP 17372. Published national benchmarks put a typical mold remediation project at $1,223-$3,757 (Angi) to $1,500-$6,000 (HomeGuide); a written quote after inspection sets the real price, and the first step is always finding the water.How costs break down.
How old the homes are, how many share walls, and how often water has come in, compared with Adams County and Pennsylvania.

The sill plate rests directly on the foundation. White or dark fuzz along it, especially on the side of the house that faces the yard slope, means the wood is pulling moisture from the masonry.
When an addition smells different from the rest of the house, the crawl space underneath is usually the reason. Damp air from bare soil rises through gaps around pipes and into the room.
A pressure tank, cold water line, or water heater dripping in summer puts a steady supply of water onto nearby joists and storage. Mold often starts right there.
Cardboard and paper stored against basement walls show mold before the walls do. Spots or a damp feel on the bottom of boxes is an early warning.
Rust appearing on things stored in the basement means the air is staying humid for long stretches. The same air is feeding mold on wood and fabric.
Huntington Township has almost no flood history: 2 flood insurance claims, and neither one paid. The moisture in most homes comes from the ground and the air. Stone and block walls let soil moisture pass through slowly, and that moisture evaporates into the cellar all year.
In summer, warm humid air gets into basements through old windows, bulkhead doors, and sill gaps. When it touches cool masonry and cold water lines, it condenses. The basement can sit above 70% relative humidity for weeks without any visible water.
Additions are a second weak spot. Many were built over shallow crawl spaces with bare soil, and the connection to the original house is rarely well sealed. Damp crawl space air rises into the addition, and the joists underneath can stay wet enough to support mold.
In Huntington Township, the work is split between old farmhouse cellars and newer country homes. Floods are rare here, so most jobs come down to ground moisture and humid air.
Farmhouse cellars and 1980s block basements that stay damp.
Farmhouse cellars and 1980s block basements both pass moisture from the ground. We remove moldy storage and finishes under containment, clean the framing and walls, and set up a dehumidifier that drains on its own so the space stays below 60%.
Crawl spaces under additions on older houses.
Additions on older houses often sit over crawl spaces with bare soil. We clean the joists and subfloor, lay a sealed vapor barrier, and check the seam where the addition meets the original house, since water and air both get in there.
Finding the moisture source in a rural house before deciding what to fix.
When the source is not obvious, an inspection with moisture readings, humidity logs, and surface temperatures shows whether the problem is the ground, the air, or a leak. That keeps you from paying to fix the wrong thing.
Every service we offer is available in Huntington Township.
We look at grading, downspouts, and gutters, and note where water is collecting against the foundation. Simple drainage fixes often cut basement moisture more than anything done inside.
The affected area is sealed off with plastic and kept under negative air pressure with HEPA filtration. Moldy storage and finishes are removed, and framing is cleaned.
Bare soil under additions gets a sealed vapor barrier, and open vents are addressed so humid summer air stops condensing on the framing.
A dehumidifier that drains to a floor drain or sump keeps the basement below 60%. A separate hygrometer lets you confirm it is working.
On rural properties, we check the outside first: where downspouts empty, how the ground slopes toward the house, and whether a pressure tank or water heater in the basement is leaking or sweating.
Huntington Township is a longer drive up U.S. 15, so we plan drying checks on a set schedule and bring the equipment we expect to need on the first visit.
Flood records back that up: only 2 flood insurance claims have been filed in the township, and neither paid out. A musty basement here almost always comes from humid summer air, moisture moving through the foundation, or a slow plumbing leak. Those are easier to fix than flood damage, but they still need the source found.
Yes. Huntington Township, including Idaville and the area along U.S. Route 15, is part of our service area.
The well itself does not cause mold, but the equipment can. A pressure tank, water lines, and a water heater in the basement sweat in humid weather and can leak at fittings. Insulating cold lines and checking fittings is a cheap way to cut a steady source of moisture.
Covering bare soil usually helps, because a dirt floor gives off a lot of moisture. The plastic should be thick, overlapped, and sealed at seams and walls to work well. In a stone cellar, keep it clear of wood framing so it does not trap water against the sill.
Usually not. If you can see it, the question is not whether there is mold but why it is growing and how far it has spread. Moisture readings answer that better than a lab sample. Testing is more useful when there is a smell but nothing visible.

Tell us whether the house is an older farmhouse or a newer home, and whether it has additions or a crawl space. That shapes the visit.
