Symptoms of Indoor Moisture Problems in South Jersey

Leaks and other indoor water intrusion and easily go unnoticed for an extended period of time. Pay attention to the signs that could be pointing you to serious indoor moisture problems.

Signs of Mold

It only take 24-48 hours for major mold to develop with adequate water. Mold is most commonly the side effect of an underlying indoor moisture problems. If you suspect potential mold development due to indoor moisture problems, you should consider calling an expert to complete a comprehensive South NJ mold inspection. A certified professional will be properly trained and equipped to safely diagnose the full extent of your mold problem and find where the water starts and stops. 

  • Musty odors– Hidden water remains stagnant and promotes mold and bacteria growth. This produces a musty, earthy smell. 
  • Visual signs of mold growth– When moisture comes into contact with dormant spores, active mold growth begins. If you identify potential mold spores developing in your property, call a mold removal company in Southern NJ.   

Suspicious Staining

Unexplained staining and/or discoloration can be the result of water damage. Water that seeps into wall and/or ceiling voids often manifests as a stain or blotch as it slowly saturates the adjacent wallboard or ceiling. Oftentimes, stains will appear to be yellowish in color. If there is mold growth developing, the stain might appear to be darker.

Peeling Wall or Ceiling Finishes

In situations where there is excess moisture buildup within the wall and/or ceiling voids, the water will eventually saturate the adjacent drywall and wall finishing. The saturation will compromise adhesion, causing the paint or wallpaper on the opposing side to raise, ripple, bubble and/or peel.

Sweating Walls

Condensation can begin to develop on walls, ceilings and/or windows if there is any underlying moisture problem in the space. Often times, your South Jersey home suffers from humidity problems, you might notice condensation developing during cooler climates. When water vapors in the air come in contact with a cold surface, the vapors cool and turn to liquid.

Areas of condensation can also develop on ceilings and walls when there is excessive moisture festering in wall and/or ceiling voids. This can be caused by a leak or a mixture of high humidity, poor ventilation and/or inadequate insulation.


If your porous building materials come into constant contact with moisture, you might notice that your materials will start to swell. As water absorbs into wood, drywall, flooring, etc., the materials will begin to swell and become visually obvious over time.

  • Swollen door casing or door alignment- As water absorbs into your door jam, the jam will swell and affect the alignment with your door. It will be difficult to actually see the swelling, but you will experience it. The door will slowly become more and more difficult to open and close.
  • Baseboards/trim separating from the wall- As building materials swell up, materials that were once flush against each other will begin to grow and push against each other and force material separation.

Sagging walls and ceilings

Excessive water collected within your building materials can impose a great deal of weight and stress on the structure of your Southern New Jersey property. With time, the excess weight and stress will reflect in your walls and ceilings. Eventually, saturated drywall and ceiling materials begin to deform and buckle. Water-soaked walls and ceilings compromise the structural integrity of the NJ home and present a safety hazard if they collapse.

Floor effects

Water most commonly seeks out and travels to the lowest level and seeps under floor coverings (i.e.: carpet, tile, vinyl, etc.) and soak into the sub-floor. If you are experiencing dampness or signs of dampness on your floors, you may need a professional dry-out. In some cases, removal of some floor coverings, particularly carpet and padding, may be necessary to effectively dry the structure. Untreated moisture collected within your flooring can lead to widespread mold growth that will require the help of a professional mold remediation company in South Jersey.
