Crawl Space Encapsulation

Protect Your Home from the Ground Up with a Clean, Dry, and Sealed Crawl Space

Your crawl space might be out of sight, but it plays a big role in your home’s health, comfort, and energy efficiency. At 62 Insulation, our crawl space encapsulation service is designed to eliminate moisture, improve air quality, and protect your home’s foundation — all while lowering energy costs.

What Is Crawl Space Encapsulation?

Crawl space encapsulation involves sealing your crawl space with a heavy-duty vapor barrier, insulating the walls or subfloor (depending on your home’s design), and controlling moisture through ventilation or dehumidification. The result is a clean, dry, and controlled environment beneath your home.

Who This Is For

Crawl space encapsulation is ideal for:

Homeowners experiencing musty odors, cold floors, or uneven indoor temperatures
Homes with excessive moisture, standing water, or visible mold in the crawl space
Those with allergies or asthma, where air quality is a top concern
Anyone planning to improve their home’s efficiency, durability, or resale value

Why Crawl Space Encapsulation is Important

An unsealed crawl space can lead to serious — and expensive — problems over time. Without protection, moisture from the ground seeps into the space, encouraging mold growth, wood rot, pest infestations, and poor air quality. Because up to 50% of the air in your home can come from the crawl space, what’s down there affects your whole house.

Encapsulation offers long-term protection and peace of mind:

Moisture Control – Stops ground moisture and high humidity from damaging your structure
Mold & Mildew Prevention – Helps keep allergens and spores out of your living space
Improved Indoor Air Quality – Healthier air for your family, especially those with respiratory concerns
Energy Efficiency – Reduces heating and cooling loss, especially with added insulation
Pest Deterrence – Creates a less hospitable environment for insects and rodents
Foundation Protection – Reduces the risk of wood rot, rusting, and structural damage over time

Frequently Asked Questions

When is a good time to add insulation to my attic?

A good time to add insulation to your attic is when you're experiencing high energy bills, uneven indoor temperatures, or noticing drafts — especially during extreme seasons like summer and winter. It's also ideal to upgrade during home renovations, roof replacements, or if your current insulation is old, damaged, or settling below recommended levels.

How long will it take to have my attic insulation removed and reapplied?

We recommend that our customers expect an attic overhaul to happen between 1-3 days, depending on the size and shape of the attic.

Will cellulose or spray foam make my house too tight?

Cellulose and spray foam insulation, especially when paired with proper air sealing, can significantly reduce air leakage — but they won’t make a home too tight if installed correctly. A well-insulated home still needs controlled ventilation, which can be easily managed with systems like bath fans or energy recovery ventilators (ERVs). In fact, sealing a home properly helps improve comfort, energy efficiency, and indoor air quality — as long as ventilation is part of the plan.
