Crawlspace Masters

Crawlspace Masters lists Sullivan, Indiana, in the contact footer of its website, with 812-645-1157 as the main telephone number. The listed contact includes a post-office box. This directory uses Sullivan as a documented contact locality and does not represent that mailing information as a verified walk-in office. The company describes crawl-space cleanup, encapsulation and waterproofing, along with dehumidifier equipment, sump pumps, mold treatment, rotten floor-joist repair and access-door installation. Its homepage says inspections may include photographs and video to explain conditions under the home before a course of work is recommended. The dedicated encapsulation page describes removing debris and old insulation, treating mold, installing foam insulation and sealing foundation vents. It then describes placing a vapor barrier across the floor, piers and walls, sealing the liner sections together and installing a dehumidifier. Confirm which of these steps are included in the proposal for your particular crawl space. Ask for a written scope that separates cleanup, moisture control, equipment and any wood repairs. For an encapsulation proposal, clarify liner coverage, seam sealing, access details and the humidity-control method. For sump-pump or dehumidifier work, ask where water will drain and which maintenance tasks remain your responsibility. Sources were reviewed October 14, 2026 through indexed website extracts.
