Crawl Space Encapsulation in Lawrenceville & Metro Atlanta
Crawl Space Encapsulation in Lawrenceville & Metro Atlanta
Protect Your Home’s Foundation, Eliminate Musty Odors, & Seal Out Damp Soil Moisture
If you have a traditional vented crawl space, you probably don’t spend much time thinking about what’s happening underneath your floorboards. After all, if it’s out of sight, then it’s out of mind. But during humid summers and rainy falls, that dark space beneath your feet plays a huge role in your home’s air quality, energy bills, and overall comfort.
In North Georgia, wet red clay soil and open foundation vents create a constant stream of rising moisture. At Cool Masters Services, our crawl space encapsulation systems seal out ground vapor, stop floor rot before it starts, and keep the air your family breathes clean and dry.
Signs Your Crawl Space Has a Moisture Problem
You don’t have to actually crawl under your house and see for yourself to know moisture is causing trouble. If you notice any of these warning signs, moisture underneath your floors is usually what’s causing it:
- Earthy or musty smells that linger in your first-floor rooms, closets, or whenever your air conditioner turns on.
- Hardwood floors that warp or cup along the edges, sometimes feeling slightly soft underfoot.
- A sticky, clammy feeling indoors during the summer months, even when your AC has been running all day.
- Freezing floorboards in the winter, often caused by wet, heavy insulation pulling away from your subfloor.
- Water droplets forming on metal vents, baseboard trim, or window panes.
- Unwanted bugs and pests indoors, like spiders, mice, or silverfish drawn to damp wood underneath your house.
What We Do During a Crawl Space Encapsulation
When you hire our team to encapsulate your crawl space, we don’t just throw down a thin sheet of plastic and call it a day. Instead, we take the time to install a complete, heavy-duty moisture barrier system built for Georgia’s soil conditions:
1. Before doing anything, we check your wood for moisture, look over your ductwork, inspect your floor joists, and check for active water leaks.
2. We haul out old debris, trash, and wet insulation that’s been holding onto moisture against your floorboards.
3. We line the entire ground floor, walls, and piers with a thick, tear-resistant 20-mil white sheet, sealing all the edges so moisture stays trapped under the plastic.
4. We seal off exterior vents and rim joists to stop hot summer air and icy winter wind from blowing under your home.
5. We add a powerful crawl space dehumidifier that drains itself outside, automatically keeping the air under your home dry and crisp.
Have questions about what’s going on underneath your house?
No two crawl spaces are the same. We’re always happy to take a look, point out what we see, and answer any questions to make sure you feel comfortable throughout every step of the process.
The Real Benefits You'll Notice Upstairs
- Protect Your Subfloors: Wood-destroying fungi can’t grow without moisture. Sealing your crawl space preserves your floor joists, beams, and subflooring for the long haul.
- Lower Utility Bills: Stopping drafts and humidity means your HVAC system doesn’t have to work nearly as hard, saving you money on monthly heating and cooling.
- Better Indoor Air Quality: Knocking out crawl space mold and dust mites goes a long way toward reducing morning allergy symptoms and sinus congestion.
- Warmer Floors in Winter: No more freezing hardwood floors underfoot in December and January.
- Clean Extra Storage: An encapsulated crawl space turns a dirty dirt pit into a bright, dry area where you can safely store plastic bins and holiday decorations.

Frequently Asked Questions
How much does crawl space encapsulation cost in Metro Atlanta?
Crawl space encapsulation in Metro Atlanta costs between $5,000 and $12,000+ on average, although the total cost can vary depending on:
- Overall square footage and ceiling height under the home.
- The prep work required, like removing wet insulation, mold treatment, or clearing debris.
- The thickness of the vapor barrier used (such as heavy-duty 20-mil reinforced liner).
- Any added drainage systems, such as French drains or a sump pump.
- The dehumidifier setup needed to get rid of the amount of moisture present.
Will encapsulating my crawl space increase my home's resale value?
Yes, crawl space encapsulation increases home resale value and prevents costly seller concessions. Home inspectors in North Georgia heavily evaluate crawl spaces during real estate transactions. An encapsulated crawl space reassures buyers, protects structural integrity against wood rot, and eliminates buyer concerns over any damage to the home’s foundation or other issues that may come up down the line.
How long does it take to encapsulate a crawl space?
A professional crawl space encapsulation takes 1 to 3 days to complete. Smaller homes with minimal debris require about 1 to 2 days, while larger crawl spaces needing drainage systems, mold remediation, or extensive insulation removal take up to 3 days.
Can I encapsulate my crawl space myself?
You should avoid DIY crawl space encapsulation because improper sealing traps moisture and accelerates wood rot. Without professional vent sealing, tight seam taping, and a commercial dehumidifier to actively pull moisture out of the air, laying plastic on the ground often traps water against the subfloor, creating unseen mold growth.
Do I still need fiberglass insulation under my floors after encapsulation?
No, you do not need fiberglass floor insulation once your crawl space is encapsulated. Standard fiberglass batts trap moisture and sag over time. Once your foundation walls and vents are properly sealed, the air under your house stays dry and close to your indoor temperature, keeping your floors naturally warm all winter without messy insulation under your floorboards.
