Moisture Services & Pricing

(Commercial and Residential Services Available)

Moisture Control Procedure:

  • We will visually inspect the potentially affected area (inside or outside) to check for problem areas, use a moisture meter to measure the water content of the air, provide a free estimate for the installation of moisture prevention methods, and proceed with the installation process.
  • We may possibly use moisture barriers, a french drain system, dehumidifiers, and vents to rid your property of excess moisture. We may also use special cleaning materials and fungicides. These special cleaning materials and fungicides can possibly be harmful if they come into contact with skin, are ingested, or are inhaled.
  • The inspection cost is $125 and will be applied to the final cost of all the work performed. The time it takes to complete the process and the cost of the treatment/installation varies. These figures depend on the size of treated areas and the number of methods we employ to control excess moisture on your property. For example: a moisture barrier normally takes a few hours to install, whereas a french drain system may take days.
  • Please note that we are not licensed mold specialists. A licensed mold specialist would need to officially determine if mold is present in your home.

Moisture Prevention:

The best way to prevent future issues is to schedule regular yearly visits from a pest control professional. This inspection can be coupled with your annual termite inspection and the cost will start at $150.

Moisture Barrier & French Drain System

If you have moisture issues, a French Drain System and a moisture barrier are usually installed at the same time. Cost of installation varies and depends on the area of coverage.

Moisture Barrier

Moisture Barrier

  • The materials we use are standard in the industry. The sheets we install in your crawl space are made of 6-20 mil polyethylene and secured with tape if needed.
  • A lining with this material will need to be replaced every 25 years to ensure continued protection. In order to maintain the materials and moisture protection for at least 25 years, the homeowner should avoid tearing or putting holes in the sheets. We encourage you to avoid storing any items in the crawl space.
  • We will ensure 80% coverage according to SC standards.
  • The cost for a moisture barrier installation and materials varies and depends on the size of the area being covered.
  • Moisture barriers should be installed after the construction of a new home is completed.

French Drain System

French Drain System

The materials we use are standard in the industry. They include corrugated/perforated pipe, #5 gravel, and a Zolar M-53 sump pump housing.

Steps for Installing French Drain System

  1. Dig out soil to create ditch lines around the inside of the foundation wall
    • ditch lines start at a depth of 12 inches and are measured to ensure they taper & flow down hill
    • Install at least 4 inches of gravel in bottom of ditches followed by corrugated pipe.
  2. Dig out soil to install sump pump and housing
    • Dig pump housing depth at least 10 inches deeper than the deepest ditch line so that the ditch lines will feed the pump and prevent standing water in ditch lines.
    • Install pump inside the housing. Plumbing will extend from the pump and exit beneath the wall through existing pipe that leads to drainage ditch.
    • Install GFI (Ground Fault Interrupts) so that the flow of electricity to the sump pump will be shut off in case of pump electrical problems. State law requires the installation of a GFI with the installation of a French Drain System.
  3. Install moisture barrier that covers at least 80% to keep moisture levels down to a normal level.

Warranty

All drains come with a full guarantee at time of completion. Any additions and/or changes to the structure at ground level which may interfere with the drain are excluded. In order to keep the drain warranty, an annual inspection is required. This inspection may be completed at the time of the termite inspection if treatment has been performed. If treatment has not been performed, annual fee for pump warranty to be in effect.

Moisture Identification & Issues

Identification:

  • MDE Pest services specializes in moisture issues in the property crawl spaces.
  • Moisture can be found anywhere in your home. You may be able to identify moisture issues by visually inspecting to look for fungi (mold and mildew which may be green or black in color), rotting wood, or discoloration of surface areas.
  • Sensitive noses may also be able to detect a musty or earthy smell of mold or mildew even without being able to see it.

Harm to Health or Property:

  • Moisture combined with the right temperature, mold food, and mold spores creates the perfect environment for mold growth.
  • Those affected by asthma or other respiratory conditions should minimize their exposure to mold growth in order to remain healthy. People with severe allergies are at risk and may develop nasal, throat and/or respiratory irritations and may have difficulty breathing.
  • A licensed mold specialist would need to determine if mold is present in your home.
