Vapor Barrier Installation
Moisture is one of the biggest threats to your home’s foundation and indoor air quality. At Redo Attics and crawlspace, we offer expert vapor barrier installation to keep your crawl space dry, protected, and energy-efficient—all while helping to prevent costly structural and health issues.
What Is a Vapor Barrier?
A vapor barrier is a durable plastic or polyethylene sheet installed on the ground and walls of your crawl space. Its main job is to block moisture and humidity from rising up into your home through the soil.
Why You Need a Vapor Barrier
Without proper moisture control, crawl spaces can become a breeding ground for:
Mold and mildew
Wood rot
Poor air quality
Increased pest activity
Higher energy bills
Installing a vapor barrier creates a clean, dry environment beneath your home—protecting your insulation, subfloor, and air quality.
Our Process
Inspection & Moisture Assessment
We evaluate your crawl space for water intrusion, humidity levels, and existing damage.
Surface Prep & Cleaning
We remove debris, old vapor barriers, and contaminated insulation to prepare the space.
Barrier Installation
We install a thick, puncture-resistant vapor barrier that fully covers the crawl space floor and, if needed, the walls—tightly sealed and secured to prevent gaps or sagging.

Crawl space insulation
Sump pump or drainage solutions
