What is crawl space encapsulation?

Crawl space encapsulation is the process of sealing your crawl space with a heavy-duty moisture barrier to prevent ground moisture, mold, pests, and outdoor air from entering your home. It typically includes cleaning, sealing vents and openings, installing a vapor barrier on floors and walls, and adding insulation and dehumidification as needed.

How much does crawl space encapsulation cost in Atlanta?

The cost varies based on crawl space size, condition, and specific needs. Most Atlanta homes range from $5,000 to $15,000. Hydroguard provides free, no-obligation estimates with transparent pricing—we assess your space and recommend only what you need.

How long does encapsulation last?

A properly installed crawl space encapsulation system can last 15-20 years or more. The vapor barrier itself is highly durable, and with periodic inspections and maintenance, your system will continue protecting your home for decades.

Will encapsulation reduce my energy bills?

Yes. Encapsulation creates a thermal barrier that helps regulate temperature, reducing the workload on your HVAC system. Many homeowners see a 10-20% reduction in heating and cooling costs after encapsulation.

Do I need a dehumidifier after encapsulation?

In most cases, yes. While the vapor barrier dramatically reduces moisture, a crawl space dehumidifier ensures humidity stays at optimal levels (typically 50-55%). This prevents any residual moisture from causing mold or wood rot.

Can I use my crawl space for storage after encapsulation?

Absolutely. Once encapsulated, your crawl space becomes a clean, dry area suitable for storage. Many homeowners use the space for seasonal items, tools, or other belongings that need protection from moisture.

How does encapsulation improve indoor air quality?

Up to 50% of the air in your home comes from your crawl space. Encapsulation prevents mold spores, allergens, and musty odors from entering your living areas, resulting in cleaner, healthier air for your family.

Is encapsulation required by building codes in Georgia?

While not always required, Georgia building codes do mandate moisture control measures in crawl spaces. The International Residential Code (IRC) recommends vapor barriers and proper ventilation or conditioning. Encapsulation exceeds these standards and is considered best practice.
