Anthem Insulation & Home installs and replaces crawl space insulation for Canton homeowners, and it’s one of the insulation services we provide in Canton from our Woodstock office. We have 10 years of experience working under houses, and each project starts with a free home energy audit that includes a full look at the crawl space.

The Importance of Crawl Space Insulation in Canton

Canton gets around 50 inches of rain a year, and the red clay soil common across North Georgia drains slowly. The ground under a house can stay damp long after a storm has passed. Summer adds another source of moisture. Warm, humid outdoor air enters through the foundation vents, meets cooler ductwork, pipes, and floor framing, and condenses.

Those conditions are hard on insulation. Fiberglass batts between the floor joists absorb moisture, get heavy, and sag or drop to the ground. Once that happens, the floor above has no thermal protection, and the wet batts hold moisture against the wood. Good crawl space insulation in Canton has to account for moisture as well as temperature.

Signs of Failing Insulation

Cold floors in winter are what most homeowners notice first, especially on hardwood and tile over the crawl space. A musty smell on the first floor, higher indoor humidity in summer, and heating bills that seem high for the size of the house are other common signs.

Under the house, the evidence is easier to read. Batts hanging down or lying on the ground, dark or matted fiberglass, water droplets on ducts, and white or gray growth on joists all indicate a problem. Insulation falling down in a crawl space is usually caused by moisture, missing supports, or pests pulling it loose for nesting.

Floor or Wall Insulation

Crawl space insulation is installed in one of two ways, and the right one depends on whether the space is vented.

In a vented crawl space, the insulation goes in the floor. We fit batts between the joists, tight against the subfloor, and hold them in place with wire supports. Faced batts are installed with the facing up toward the heated room. Gaps and compressed sections reduce performance, so we cut each piece to fit around plumbing, wiring, and blocking.

In a sealed crawl space, the insulation goes on the foundation walls instead. The vents are closed, the ground is covered, and the walls are insulated so the crawl space stays close to the temperature of the house. Closed-cell foam is our usual material for this, and our spray foam insulation in Canton includes crawl space walls and rim joists. This approach protects ducts and pipes in the crawl space and keeps the floors above warmer.

Handling Moisture First

New crawl space insulation won’t last if the space is wet. During the audit we look for standing water, damp soil, plumbing leaks, clogged or missing vents, and gutters or grading that send rainwater toward the foundation. Those issues need to be corrected before we install anything.

A vapor barrier on the ground is the basic step. It’s a heavy plastic sheet that covers the soil and stops ground moisture from evaporating into the space. For crawl spaces with ongoing humidity problems, crawl space encapsulation goes further. It seals the ground, the walls, and the vents, and it’s often paired with a dehumidifier. Insulation and encapsulation work best when they’re planned together.

Removing Old Crawl Insulation

Wet, moldy, or pest-damaged batts have to come out before new crawl space insulation goes in. Our crew pulls down what’s still hanging, collects what has fallen, bags all of it, and carries it out through the access door. We also clear debris from the ground so the vapor barrier lies flat. If the joists show mold growth, we point it out so it can be treated before the new material covers it.

Materials We Install

We use three materials in Canton crawl spaces. Fiberglass batts are the standard for floors over vented crawl spaces and the most affordable option. Mineral wool batts cost more, but they’re denser, hold their shape, and don’t absorb water. Closed-cell spray foam goes on foundation walls and rim joists, where it insulates, air seals, and resists moisture in one layer.

The rim joist deserves attention in every crawl space. It’s the band of framing on top of the foundation wall, and it’s one of the leakiest parts of most houses.

Audits, Pricing, and Discounts

The free home energy audit covers the crawl space’s size and height, the condition of the existing insulation, moisture levels, and the ductwork. Pricing for crawl space insulation depends on square footage, the material, how much removal is needed, and how tight the working space is.

We have a new build and i called Anthem Insulation for a price. They came out walked through my property with me and went over what our expectations were on the insulation. Hunter was phenomenal and answered all my questions (and i had many!) there pricing was fair, they communicate along the way and really go the extra mile to make sure the customer is happy! Even our county inspector for the house was amazed how thorough they were, passed on first site (which in new construction theres usually always something missing- not with Anthem! ! Will definitely use them again for any future projects

Megan Naputano

Sawyer and his team did an exceptional job with our blown insulation project. Our project was unique as the team had no access to the attic and had to work through speaker holes and can light holes. The team was respectful of all of our belongings, laying down tarps and plastic. The team was patient and happy to work with all my pickiness and oversight. Definitely recommend Anthem Insulation for your home or business.

Scott Andrews

I had a great experience working with them. The price they quoted was lower than I was expecting. They were not pushy, even though it took me 3 months to get around to scheduling the work after the estimate. The spray insulation work was high quality, and looks great.

I was unexpectedly not able to be home when they showed up to do the work so I left the door unlocked and the check on the counter. They were super professional, and took care of everything without me needing to be there. Couldn’t ask for anything more, I’d definitely recommend this place.
