Crawl Space Moisture Control
Offering crawl space moisture solutions for your peace of mind
Charlotte's Moisture Control Experts
Protect your home from the ground up
At Palmetto Exterminators, we know your crawl space may be out of sight, but it's far from unimportant. Excess moisture in your Charlotte home can lead to serious issues that often go undetected until significant damage has occurred.
Moisture in the crawl space creates ideal conditions for mold growth, structural damage, and poor indoor air quality. It also attracts destructive pests like termites, powderpost beetles, and rodents—leading to even more damage and expensive repairs.
How We Control Moisture
Our moisture control services are designed not just to treat symptoms, but to prevent future problems and protect your home long-term. We start with a thorough inspection to identify where excess moisture is coming from and how it's affecting your home. From there, we develop a customized plan tailored to your crawl space conditions.
Our team removes old or damaged insulation and vapor barriers that may be trapping moisture or harboring pests. We then install new, high-quality vapor barriers to block ground moisture, set up commercial-grade dehumidifier systems to control humidity levels, and, if needed, install crawl space doors to keep moisture and pests out.
These upgrades work together to create a dry, sealed, and protected crawl space environment.
What Moisture Does to a Home
Excess humidity and water buildup create the perfect environment for mold and mildew growth, wood rot, and structural weakening. It also attracts unwanted pests like termites, carpenter ants, powderpost beetles, cockroaches, and rodents—many of which thrive in damp conditions. These pests can cause further destruction to wooden structures, insulation, and wiring, and some may even carry harmful bacteria or allergens into your living space.
Homes in Charlotte are especially vulnerable due to the region's warm, humid climate, frequent rainfall, and poor drainage conditions around many foundations. Without proper protection, moisture can quietly compromise both the structure and safety of your home.
How do I know if I need moisture control?
Common signs you may need moisture control include:
- Musty odors
- Visible mold or mildew
- Sagging floors
- High indoor humidity, causing condensation on windows or pipes
- Increased pest activity—especially in basements or crawl spaces.
If you notice any of these warning signs, our Charlotte crawl space professionals can help determine if moisture is the root cause and recommend the necessary solutions.
How long does it take to install a vapor barrier?
Vapor barrier installation takes about one or two days, depending on the size and condition of your area. If additional services, such as insulation removal or dehumidifier setup, are required, the timeline may vary slightly. However, we always work efficiently to minimize disruption to your home.
Do dehumidifiers need maintenance?
Yes, dehumidifiers do require routine maintenance to operate effectively. This typically includes checking and cleaning the filters, draining collected water (unless it's a self-draining unit), and inspecting for any clogs or performance issues. Palmetto Exterminators can provide maintenance guidance or schedule service visits to keep your system running smoothly.
What’s the difference between a vapor barrier and full encapsulation?
A vapor barrier is a layer of plastic sheeting installed on the ground of your crawl space to reduce moisture coming up from the soil. It provides a basic level of protection and is ideal for many homes.
Full encapsulation takes it a step further by completely sealing the crawl space—covering walls, floors, and sometimes ceiling joists.
Will moisture in my crawl space affect my energy bills?
-
Yes, excess moisture can increase your energy bills.
-
When your crawl space is damp, it affects the insulation and air quality throughout your home—forcing your HVAC system to work harder to maintain a consistent temperature. By controlling moisture with vapor barriers and dehumidifiers, you can improve energy efficiency and potentially lower your monthly utility costs.
