Anderson Heating, Air & Insulation (formerly John Anderson Service Company, est. January 1978) — BPI Certified experts in sealed, conditioned crawlspaces with vapor barriers, insulation, and dehumidification across Calhoun, Dalton, Rome & NW Georgia.
Anderson Heating, Air & Insulation provides crawlspace encapsulation, vapor barriers, and dehumidification across Northwest Georgia. As BPI-certified building-performance contractors, we treat the crawlspace as part of your home's whole-home energy envelope — not just a pest or moisture problem. Family-owned since 1978 and based in Calhoun.
Most homes in Northwest Georgia have crawlspaces that act like a sponge — pulling moisture, mold spores, and allergens into your living space. Anderson Heating, Air & Insulation (formerly John Anderson Service Company) became BPI Certified specifically to fix these hidden problems the right way.
"We don't just cover the dirt. We turn your crawlspace into a dry, healthy part of your home."
— The Anderson Difference
We measure moisture levels, test for mold, and design a custom encapsulation plan based on your home's specific conditions.
We don't treat the crawlspace in isolation. We make sure it works with your insulation, air sealing, and HVAC system.
Hundreds of families in Calhoun, Dalton, and Rome have seen drier homes and lower bills after our crawlspace work.
Family-owned since 1978. We know how Georgia's climate affects crawlspaces and how to fix them permanently.
Crawlspace encapsulation seals your crawlspace with a heavy-duty vapor barrier on the floors and walls, combined with insulation and often a dehumidifier, turning it into a conditioned, dry space instead of a damp, moldy one.
It stops moisture and mold, improves indoor air quality, reduces energy bills by making your HVAC more efficient, and can even increase your home's value and structural longevity.
Yes. Georgia's humid climate makes encapsulation one of the highest-ROI home improvements. Many customers see payback through lower energy bills and avoided mold repairs within 5-7 years.
Most residential crawlspaces are completed in 2-4 days depending on size, access, and whether insulation or dehumidification is added.
Yes. We offer financing through Optimus (GreenSky, Wisetack) and senior/military discounts to make this important upgrade affordable.
