Keeping a Mold-Free Crawl Space Through The South Jersey Winter

Crawl spaces are hot spots for mold problems and moisture problems throughout New Jersey and the South Jersey region.

Homeowners should take this opportunity to check your South NJ crawl space, so you can assess for and promptly address any signs of moisture concerns in the space.

Mold Prevention Tips To Maintain A Mold-Free Crawl Space

Something as simple as taking the time to take a quick peak at your foundation walls or checking your crawl space insulation can go a long way in avoiding significant mold damage and a costly mold cleanup in the future. Moisture control and routine maintenance are vital to maintaining a mold-free crawl space.

Routine Leak Checks

  • Routinely check for signs of water leaks in the crawl space.
  • Check your crawl space ceiling and foundation walls.
  • If you identify signs of damage, you should address it immediately to prevent any potential water intrusion.
  • Check all HVAC components and plumbing systems in the crawl space for leaks or condensation.
  • It is important to dry leaks IMMEDIATELY to prevent additional damage.

Check your Foundation

  • Look for any cracks, masonry damage, or interior signs in our main living space– these can all be warning signs of foundation damage in NJ.  
  • Manage drainage around your foundation. It is important that all rain runoff is draining away from your Southern New Jersey property.

Maintain Gutters & Downspouts

  • All gutters and downspouts should direct water AWAY from foundation walls.
  • Water that flows towards the home can seep into the crawl space and cause water damage and mold development.
  • Clean your gutters regularly– your gutters should be free of all debris to avoid backups.
  • Clogged and overflowing gutters can lead to roof damage and water buildup around the foundation walls.  

Install a Vapor Barrier

  • A NJ crawl space vapor barrier is a layer of plastic installed over the dirt floor of a crawl space.
  • Vapor barriers control moisture levels by slowing or preventing the evaporation of ground moisture into the crawl space air.
  • If you detect signs of excessive crawl space moisture, a vapor barrier can help.

Assess your Insulation

  • Check the condition of your crawl space insulation at least twice a year.
  • Always conduct checks after any water intrusion, pest infestation, or any other crawl space problems.
  • Look for sagging or missing insulation. Damaged insulation can be an indicator of water problems.
  • Damaged insulation cannot do its job properly and will be ineffective in preventing moisture buildup and allow mold development.
  • It is important to properly replace any damaged insulation as soon as possible.
  • If your crawl space is not already insulated, you should consider hiring a professional to properly install insulation in your crawl space.
  • Crawl space insulation helps to regulate crawl space temperatures and its environment– this will help to prevent humidity and condensation.

Sufficient Ventilation

  • Properly installed and sufficiently sized crawl space vents can help air flow to aid moisture control.
  • It is recommended that there be 1 square foot of ventilation for every 150 square feet of crawl space.
  • However, ventilation needs depend on various factors, so please consult a professional for an expert opinion. There will be times when vents may be better off closed rather than open.
  • Make sure that vents from other parts of the home empty outside and away from the home. For example, if your dryer vents empty into your crawl space, you may face some serious humidity issues.

Place a Dehumidifier

  • Placing a dehumidifier in your crawl space can help to keep your crawl space dry.
  • Make sure that you pick a dehumidifier that is the right size and capacity for the needs of that specific space to ensure effectiveness.
  • Regular dehumidifier maintenance will help to preserve the quality and effectiveness of your unit.
