Crawlspace Encapsulation
Full seal-up with a heavy-duty liner, tape and fasten, closed vents and a right-sized dehumidifier.
Learn moreRosewood is one of Spartanburg’s well-known residential neighborhoods where mid-century homes and established lots mean aging crawlspace systems. JHS Crawlspace Specialist provides professional encapsulation, vapor barriers, and dehumidifier installations designed for Rosewood homes.
Rosewood is a well-established Spartanburg neighborhood with homes built primarily during the 1960s and 1970s — a period when crawlspace design relied heavily on foundation vents and thin vapor barriers to manage ground moisture. In theory, the open vents would allow air circulation to keep the space dry. In Spartanburg’s humid climate, the opposite happens: warm, moisture-laden air enters through the vents, hits cooler surfaces inside the crawlspace, and condensation forms on everything from ductwork to floor joists.
We’ve inspected crawlspaces throughout the Rosewood neighborhood and the findings are remarkably consistent: original 4-mil or 6-mil vapor barriers that have disintegrated into scraps, insulation that has fallen from the joists and sits in piles on the dirt floor, humidity readings in the 75–85% range, and visible mold growth on wooden structural members. Many Rosewood homeowners first notice the problem as a persistent musty odor in the home that no amount of air freshener or carpet cleaning will fix.
For Rosewood homes, encapsulation is typically the most cost-effective long-term solution. We strip out the old vapor barrier and any fallen insulation, treat any active mold, then install a sealed 20-mil liner across the entire floor and up the foundation walls. We close all foundation vents, seal around pipes and penetrations, and install a properly sized commercial dehumidifier with a built-in humidistat. Most Rosewood homeowners see humidity drop from the 80s to below 55% within 48 hours of installation.
