Project Overview

Customer: Benjamin Mahlon Hahn

Project: Crawl Space Clean-Up, Insulation, Vapor Barrier & Dehumidifier

Address: 234 Wythe Creek Rd, Poquoson, VA

Estimate #: 1423

Date: 09/30/2026

Area of work: the crawl space under the first floor

Scope of Work — Included

Crawl Space Clean-Up with Insulation Removal — 1 jobFull clean-out of the 1,385 sq ft crawl space: the old ground cover, the existing floor insulation, debris and trash come out and get hauled away, so the floor is clear before the new barrier goes down.
Remove Existing Floor Insulation — 1,385 sq ftThe existing insulation is taken out of the floor joist bays as part of the clean-out — included at no charge.
New Floor Insulation — 1,385 sq ftNew R-19 faced batt insulation is installed between the floor joists and secured in place, so the floor above keeps its warmth instead of feeding heat into a damp crawl space.
New Vapor Barrier — 1,385 sq ftA new white 10 mil vapor barrier covers the crawl space floor — ground only, not up the walls — lapped and sealed at the seams and secured, so the ground stops putting moisture back into the new insulation.
Dehumidifier — AprilAire E100, 1 eaAn AprilAire E100 crawl space dehumidifier with its condensation pump is supplied and installed, so the unit pulls the moisture out of the air and the pump moves that water up and out of the crawl space.
Seal the Vents — 1 jobThe foundation vents are sealed from the inside so outside air and moisture stay out of the crawl space.
