Project Overview
Customer: Alanna Burns
Project: Crawlspace Cleanup, Vapor Barrier & Dehumidifier
Address: 3756 Lake Powhatan, Williamsburg, VA 23188
Estimate #: 1411
Date: 09/22/2026
Area of work: 800 sq ft townhome crawlspace · floor barrier, vents and dehumidifier
Included Scope of Work
  • Clean Up & Debris RemovalFull clean-out of the 800 sq ft crawlspace: the old vapor barrier and all debris are removed and hauled off (under one truck load), and every loose section of the existing floor insulation is repinned and rehung in place — the existing batts only, nothing added or replaced.
  • Vapor Barrier — 10 mil WhiteA white 10 mil vapor barrier is installed across the crawlspace floor (800 sq ft), measured and cut on-site, pinned and sealed at the seams and around the perimeter. Floor only — the barrier does not run up the walls.
  • Seal VentsAll six crawlspace foundation vents are sealed off from the inside to block outside air and moisture.
  • AprilAire E100 Dehumidifier with Condensate PumpAn AprilAire E100 (100 pint) dehumidifier with its companion condensate pump is supplied and installed in the crawlspace, with the condensate discharged outside the crawlspace-door wall and down the yard grade toward the lake.
  • Electrical Outlet — Dedicated CircuitA new dedicated outlet and circuit is run from the interior first-floor panel to power the dehumidifier, installed by our licensed electrician, who also pulls the permitting from the City of Williamsburg. The outlet is installed after all paperwork with the City of Williamsburg is filled out and approved and the permit is issued.
  • Door Insulation — Existing DoorInsulating foam board is added to the back side of the existing crawlspace door and sealed tight. The existing door stays — no new door and no framing.
  • General ConditionsMobilization, protection of the work area, material runs and daily clean-up through the project.
