Latimore Township is the northeast corner of Adams County, crossed by U.S. Route 15 and drained by Bermudian Creek. Nearly 95% of homes are owner-occupied, one of the highest shares in the county. North on U.S. Route 15 past York Springs, about 25 minutes from our office.
More than 1 in 5 homes here were built before 1940, above the county share of 17.5%. Yet only about 25% were built before 1960, so very little was built in between. The older houses are true farmhouses, and many have had insulation, bathrooms, and heating added long after they were built.
Most of the rest went up in the 1970s through the 1990s, with a median year of 1981. Those homes now have 40-year-old block basements, original bath fans, and attics that have been re-insulated at least once. Low ground near Bermudian Creek also stays damp, even though the township has only 1 flood insurance claim on record.
Quick answer
Latimore Township has about 1,188 homes, and 47.1% 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.

Gray or black staining on the underside of the roof that showed up after insulation was added is a classic sign of condensation. The newly cold attic is catching moisture from the rooms below.
Roofing nails that poke through the sheathing can frost over on cold mornings, then melt and drip. Rust stains around nail tips or on the insulation below mean this has been happening for a while.
Original basement windows in homes from around 1980 often leak air and water at the frame. Musty air and staining on the block beneath them is common.
On lots that slope toward Bermudian Creek or a low field, the downhill corner of the basement often stays damper than the rest. Stains or growth there follow the water table, not a leak.
Bathrooms added to a farmhouse often have fans that vent into the attic or not at all. Peeling ceiling paint and spots near the tub are the result.
More than 1 in 5 homes in Latimore Township were built before 1940, but only about 25% before 1960. The older farmhouses were built drafty, and that drafty air kept attics and walls dry. Over the years, owners added insulation, bathrooms, and tighter windows. Each change made the house warmer and tighter, but without air sealing, moist air now reaches cold surfaces in the attic and walls.
The newer homes, with a median build year of 1981, are now around 40 years old. Their block basement walls, window frames, and sill sealing have aged. Block is hollow, and water that gets into the cores can wick up and evaporate into the basement long after a rain.
Low ground near Bermudian Creek keeps soil wet, even though the township has only 1 flood insurance claim on record. Wet soil against a foundation means slow, steady moisture rather than flooding.
Latimore Township has very old farmhouses and homes from around 1980, with little in between. The attic problems and basement problems differ between the two.
Condensation mold in farmhouse attics that were insulated later.
Farmhouse attics that were insulated later often grow mold on the roof boards from house air leaking up. We remove or clean the affected sheathing under containment, then point out the air leaks at lights, chimneys, and plumbing that need sealing so it does not come back.
Block basements in homes built around 1980.
Block basements in homes from the 1970s and 1980s take on moisture through the walls and around old windows. We clean the walls and framing, remove moldy finishes or storage, and set a dehumidifier to hold the space below 60%.
Checking an older farmhouse before buying or renovating it.
Before buying or renovating an older farmhouse, an inspection shows how damp the cellar and attic really are and whether growth is old and dry or still active.
Every service we offer is available in Latimore Township.
We measure moisture in the attic sheathing, basement walls, and framing, and check humidity in each area. That shows whether the source is house air, ground moisture, or a leak.
Attic and basement work areas are sealed off and kept under negative air pressure with HEPA filtration. Moldy sheathing, finishes, and storage are removed or cleaned.
We point out air leaks at the attic floor around lights, chimneys, and pipes, and check that bath fans vent outside and the attic has working intake and exhaust vents.
The basement is dried until framing reads normal, then a draining dehumidifier keeps it below 60%. We also note grading on the low side of the lot.
In the farmhouses, we look at how the house has been changed over time: added insulation, new bathrooms, and closed-in porches all change how moisture moves.
On low ground near Bermudian Creek, we note grading and drainage in writing, since wet soil against the foundation is part of the problem even without flooding.
Often, yes. Old attics were drafty, so the roof boards stayed dry. Adding insulation makes the attic colder, and if the ceiling below has gaps around lights, chimneys, and plumbing, house air leaks up and condenses on the cold wood. Air sealing the attic floor is usually part of the fix.
Yes. Latimore Township, including the land along U.S. Route 15 and Bermudian Creek, is part of our service area.
Yes, if you air seal first. Sealing the gaps around lights, chimneys, plumbing, and the attic hatch keeps moist house air out of the cold attic. Adding insulation without sealing is what often leads to roof sheathing mold in older houses.
Yes. A bath fan that ends in the attic puts a shower worth of moisture onto cold roof boards. It should be ducted through the roof or a wall to the outside, with an insulated duct so it does not drip back.
Attic air does not usually flow down into the house the way basement air rises, but attic mold still damages roof sheathing over time. If there are ducts or an air handler in the attic, they can pull spores and smells into the house, so those get checked too.
