CleanSpace Installation - Greenwich, CT
A homeowner in Greenwich, CT expressed an interest in protecting his crawlspace from moisture. Frustrated with previous vapor barriers being inadequate in securing his crawlspace, he decided to reach out to the experts at Connecticut Basement System for assistance. Upon calling, the homeowner made contact with Sales Representative Mark Krasnickas. Krasnickas offered a free in-home consultation, providing the homeowner with suggestions for improving the space. Drafting a proposal, Krasnickas suggested our CleanSpace system, a durable, mold-resistant, moisture preventing vapor barrier. With the final proposal accepted on behalf of the homeowner, Foreman Noel Harvey and team arrived on-site. Following a quick install, the space was transformed into an encapsulated space, protected against mold, moisture, and pests!
