A damp crawlspace can lead to mold, musty odors, structural damage, and even higher energy bills. At Sump Daddy, we specialize in crawlspace encapsulation systems that eliminate moisture, block vapor, and protect your home from the ground up.

Whether you’re dealing with standing water, high humidity, or just want to prevent long-term damage, we design and install complete crawlspace solutions — including vapor barriers, sump pumps, and drainage systems — that work together to keep your crawlspace dry and clean.

What’s Included in a Crawlspace Encapsulation System

We build crawlspace systems based on the specific conditions of your home, soil, and foundation. A typical encapsulation includes:

• Crawlspace Sump Pump – Removes water that enters from below or through foundation walls
• Perimeter Drainage – Interior French drains to collect groundwater (when needed)
• Heavy-Duty Vapor Barrier – Reinforced 12–20 mil plastic sheeting sealed over soil and walls
• Seam & Pier Wrapping – Full enclosure of the crawlspace envelope, including around piers
• Insulation Options – Floor or wall insulation to improve thermal performance
• Vent Sealing – Blocking unnecessary outdoor air to stabilize conditions
• Dehumidifier (Optional) – For homes with persistent humidity even after encapsulation

Our systems are designed to control moisture at every level — from groundwater to vapor and humidity.

Why Crawlspace Moisture Matters

A wet or humid crawlspace doesn’t just damage your house — it affects your entire home’s air quality and energy performance.

Moisture problems in crawlspaces can lead to:

Mold and mildew growth

Musty smells inside the home

Buckling floors or warped framing

High indoor humidity

Rodents and pest issues

Cold floors in winter and poor energy efficiency

Since nearly half the air in your home comes up from the crawlspace, sealing and draining it properly is one of the best things you can do for indoor air quality and long-term structural health.
