4 Seasons Air Care LLC, based at 1869 Barrington Ct, Marietta, GA 30066, provides high-performance Crawl Space Encapsulation services across Metro Atlanta and North Georgia. Operating with a 4.9-star rating from 798+ reviews, our certified team specializes in transforming damp, unconditioned crawl spaces into clean, dry environments. Our technical process involves the installation of heavy-duty vapor barriers (20-mil thickness), LGR dehumidifiers, and professional sealing of foundation vents to eliminate moisture intrusion. In Georgia’s humid climate (frequently exceeding 70% RH), unsealed crawl spaces lead to mold growth, wood rot, and poor indoor air quality. We follow strict IICRC and building code standards to ensure structural integrity and a 15-25% improvement in HVAC energy efficiency. Fully licensed and insured, we serve Cobb, Fulton, Gwinnett, and DeKalb counties. For a permanent moisture solution, call (404) 891-0225.

In regions like Marietta, Roswell, and Alpharetta, the soil remains consistently damp, and the “Stack Effect” ensures that air from your crawl space eventually moves upward into your living areas. If that air is filled with mold spores, dust mites, or high humidity, it compromises your health and increases your cooling costs.
Theo như EPA, moisture control is the single most important factor in mold control. To learn more about how moisture affects your indoor environment, visit https://www.epa.gov/indoor-air-quality-iaq/moisture-control-key-mold-control. (US EPA)
Energy Savings: The Department of Energy (DOE) notes that uninsulated and leaky crawl spaces are major sources of energy loss. Encapsulation can reduce heating and cooling costs by up to 20%. To learn more about minimizing energy losses through foundation sealing, visit https://www.energy.gov/energysaver/crawl-space-insulation. (Department of Energy)
Structural Integrity: High humidity (over 60%) causes wood floor joists to absorb moisture, leading to “sagging floors” and dry rot.
Health Protection: By sealing out soil gases and allergens, you remove 99% of the pollutants that typically migrate from the ground into your HVAC system.

We go beyond simple plastic sheeting; we provide a complete engineered system:
We use FLIR thermal imaging and digital moisture meters to identify the exact points of water intrusion, including hydrostatic pressure from the foundation walls.
Before sealing, we clear all organic debris and apply EPA-approved antimicrobials to any existing mold growth on floor joists.
We install a reinforced, multi-layer vapor barrier that covers the entire floor and wraps up the foundation walls. This creates a clinical-grade seal against ground moisture.
We seal old foundation vents to prevent humid Georgia air from entering the home. We then install specialized insulation to maintain a consistent temperature, preventing condensation on your HVAC ducts.
The heart of the system is a commercial-grade LGR (Low Grain Refrigerant) dehumidifier. This unit maintains a relative humidity level below 50% year-round.
20-Mil Reinforced Polyethylene: Industrial-strength vapor barrier.
LGR Dehumidifiers: Designed for high-moisture removal in low temperatures.
Digital Hygrometers: For continuous humidity monitoring.
Industrial Air Scrubbers: Equipped with HEPA-filtration to clean the air during the process.
FLIR Infrared Cameras: To detect hidden leaks and thermal bypasses.

1. How long does crawl space encapsulation last? A professionally installed system using 20-mil barriers and LGR dehumidifiers can last 20+ years with minimal maintenance.
2. Will encapsulation stop my floors from sagging? It will stop the moisture causing the wood to soften. However, if structural damage has already occurred, we may recommend pairing encapsulation with structural reinforcements.
3. Does this help with pests? Yes. By sealing vents and removing the damp environment, you make your home significantly less attractive to termites, cockroaches, and rodents.
4. How fast is the ROI? Homeowners typically see the ROI through lower utility bills and increased property value within 3-5 years.
5. What is the “Stack Effect”? It is a scientific principle where warm air rises and escapes out of the upper levels of a house, creating a vacuum that pulls cold, damp, moldy air up from the crawl space into your bedrooms.
6. Is a dehumidifier always necessary? In Georgia, yes. Because our outdoor humidity is so high, a vapor barrier alone isn’t enough to maintain a healthy 45% humidity level indoors.
7. Do you provide a free estimate? Absolutely. We provide a comprehensive onsite inspection and moisture report for all Metro Atlanta properties.
Crawl space encapsulation involves closing the floor, walls, and the vents in a crawl space, creating a ventilation system, and dehumidifying it. The humid and high humidity of Georgia and the presence of a poorly sealed crawl space can make it a breeding ground of mold, mildew and pests and even draw moisture into the living spaces above. Encapsulation stabilizes the environment, enhances indoor air quality, eliminates structural damage and even increases the energy efficiency of a house.
The team is more than 10 years of local experience and quality that is difficult to compromise. We work with industry leading materials such as high-density polyethylene sheeting, highest rated dehumidifiers and high-tech vapor-barrier technology and a careful installation that guarantees the existence of a flawless seal. In addition to that, we support any job with an extensive warranty and a customer-first service charter that keeps you updated throughout the process.
1. Inspection & Assessment- We analyze your crawl space, examine whether you have any moisture problems, and talk about your ambitions.
2. Preparation -We clean, mend, and remove any pest or rubbish.
3. Sealing -We lay a sheet of vapor-barrier, seal seams, and affix vent covers.
4. Dehumidification – We include a special dehumidifier to maintain the moisture not higher than 30%.
5. Final Testing-we execute humidity and airflow tests to test the performance of the system and give you a report in detail.
Depending on your crawl space size and condition, pricing is determined depending on the size and the condition of your crawl space, but most Georgians spend between 2,000 and 5,000 on a full scale encapsulation project. The sealed space also means less moisture, which means your HVAC system is more efficient over time since you will see a cost of 5-10% of your heating and cooling costs decrease, and in most cases, this pays off in as few as a few years.
Each of the 4 Seasons Air Care encapsulation installations is provided with a 10 year warranty on materials and workmanship. We also offer optional maintenance plans where we plan to have annual check ups and change of filters and check up of the system. In case of any problems during warranty term like leakage or pest problems, our team will correct it without any additional cost. We would like to assure you that your crawl space will be wet, safe and healthy in years to come.
