What You Can’t See CAN Hurt You

In Poquoson, Hampton, Yorktown, and other nearby coastal towns, our homes are constantly fighting a battle against wet ground and heavy humidity.

Hidden Dangers

Your crawl space is on the front lines of this fight. Because of something called the 'Stack Effect,' air in your house moves upward just like smoke in a chimney. This means that half of the air you breathe on your first floor is actually air that was pulled up directly from the dark, damp space under your house. Consistent humidity in your crawl space that stays above 70% can cause many issues, including:

  • Wood Rot Fungi - When your wooden floor joists and support beams start soaking up water like a sponge. Over time, this causes the wood to soften and rot, putting your home's entire foundation at risk.
  • Musty odors and allergy triggers - Mold spores and dust mites (which thrive in humid environments) are a major cause of respiratory distress for families in the Hampton Roads area.
  • Destructive, moisture loving pests - Subterranean termites, powderpost beetles, rodents, and cockroaches thrive in moist areas and over time can cause major damage.

Moisture Control Services


Mares Exterminating uses a professional, multi-layered approach to ensure your crawl space stays dry for decades:

  • Vapor Barriers: We seal out the ground's natural moisture.

  • Dehumidification: We install industrial-grade systems to keep your air at the "Magic Number" (below 55% humidity).

  • Durable Sealed Doors: Custom-fitted to keep Poquoson's humid air and critters out.

  • Crawl Space Vents: Essential for allowing air to flow through the area
