Mold Remediation in Carroll Valley, PA

Why Empty Houses Grow Mold

A house that’s lived in gets air moved through it every day. Showers run with fans, the AC pulls humidity out, doors open and close. A house that’s closed up from Sunday night to Friday afternoon, or from March to Thanksgiving, does none of that. If the AC is off or set high to save money, the indoor humidity follows the outdoor humidity up past 60% and stays there. Give it a few humid weeks in July and the basement or crawl space is growing.

Carroll Valley has more of these homes than anywhere else we serve. The borough was formed in 1974 out of the old Charnita vacation development, and the population went from about 800 in 1980 to nearly 4,000 in 2020, a lot of it second homes and rentals around Liberty Mountain and the three lakes. Wooded half-acre lots, wells, septic, and crawl spaces under a good share of the houses.

The Carroll Valley Combination

Crawl spaces on sloped lots. Many of the homes here sit on a block crawl space instead of a full basement, often with a dirt floor and no vapor barrier. The ground under the house puts moisture into the air all day, and the floor joists above it are wood. White or gray fuzz on the joists and a musty smell through the floor registers is the classic result.

Tree cover. Wooded lots mean shade, slow-drying siding and roofs, gutters full of leaves, and downspouts that dump against the foundation. Water stays close to the house.

Elevation and cold. At 800 feet, winters run colder than Gettysburg’s. Pipes on exterior walls in a house with the heat set to 50 while nobody’s home are the source of some of our worst calls. A pipe lets go on a Tuesday, nobody finds it until Friday, and the water damage and structural drying window is long gone.

Well systems. A pressure tank, a well line, and no municipal drainage. One more place for a slow leak, and no storm drain out front helping the yard shed water.

What We Do Here

Most Carroll Valley work is crawl space mold: getting into the crawl, cleaning and treating every joist, and then dealing with the ground moisture with a vapor barrier or a full encapsulation and a dehumidifier so it stays dry while the house sits empty. Tight access is what drives the cost. A crawl space you can crouch in is a different job from one you belly-crawl.

The full remediation process, from containment through the light repairs that put the room back, is on the mold removal page. Attic staining on these homes usually traces to a bath fan ducted into the attic, covered on the attic mold page.

Before and After the Season

The smartest calls we get from Carroll Valley are the ones before there’s a problem: a mold inspection and air quality test in the spring before the house gets closed up for summer, or in the fall before ski season. We read the humidity, check the crawl, and tell you what to set the dehumidifier and thermostat at. It’s a lot cheaper than a remediation.

How the borough got built. The borough grew out of the Charnita development, which started in the mid-1960s, hit bankruptcy in 1970, and was bought in 1974 by Irv Naylor and renamed Ski Liberty. The borough incorporated on September 30, 1974. The Citizens Association behind it had 1,200 members, and only about a quarter of them were homeowners. Population went from 817 in 1980 to 3,940 in 2020, in 1,509 households.

Water and sewer. Most of the borough drains to the Tom’s Creek basin. The borough’s own history describes Tom’s Creek and the smaller streams as clean but subject to flooding and runoff erosion during high water. The borough sewer plant at 119 Sanders Road serves a little over 500 residences, a handful of businesses, and nearly 100 holding-tank customers. The borough also publishes septic and perc-test guidelines for the rest. A sewer extension is in the works under a 10-year plan. If you’re not sure how your lot handles water, that’s worth knowing before we pull up.
