Signs of Indoor Moisture Problems in New Jersey


Once water is loose indoors, it can flow anywhere and cause all kinds of damage to your building materials. Water can wreak havoc on your home or business if it collects in inappropriate places and is not thoroughly dried out soon enough. Water can be sneaky and inconspicuous so we have to rely on identifying the symptoms of a hidden water problem and understanding conditions that can cause hidden water damage.

If your NJ property falls victim to a serious leak or flood, you should consider contacting an emergency NJ structural dry-out company immediately to properly extract the water and thoroughly try your property. A team of professionals will be fully equipped and trained with the necessary water mitigation equipment and skills to ensure that your property is safely restored. An inadequate dry out can have serious repercussions for property owners. If the building is not thoroughly dried out, residual moisture can collect and wreak havoc on the building further down the line and leave you with serious property damage and a costly repair.

Symptoms of Hidden Moisture Problems

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 a serious underlying water problem.

Signs of Mold

It only take 24-48 hours for major mold to develop with adequate water.

  • Questionable odors– Hidden water remains stagnant and promotes mold and bacteria growth. This produces a musty, earthy smell. Where there is mold, there is a water source feeding the mold. If you suspect unseen mold growth in your property, consider calling an expert to complete a comprehensive 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. 
  • Visual signs of mold growth– Airborne mold spores are microscopic and find their way into hidden nooks and crannies in the structure of the home. So does water. When moisture contacts dormant spores, active mold growth begins. If you identify potential mold spores developing in your property, call a NJ mold removal company.   

Sweating Walls

Blotches of condensation on ceilings and walls are a common sign that excessive moisture is 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.


As water absorbs into building materials over time, the porous materials will begin to swell.

  • 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.

Stains on walls and ceilings

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.

Peeling paint or wallpaper

If there is water within the wall and/or ceiling voids, the water will eventually saturate the adjacent drywall. The saturation will compromise adhesion, causing the paint or wallpaper on the opposing side to raise, ripple or peel.

Sagging walls and ceilings

The excess water imposes a great deal of weight on walls and ceilings. Eventually, saturated drywall and ceiling materials begin to deform and buckle. Water-soaked walls and ceilings present a safety hazard if they collapse.

Floor effects

Water tends to seek out the lowest level and seeps under floor coverings like carpet, tile, and vinyl, soaking 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.


When it comes to unwanted water in your New Jersey home or business, property owners should always respond with a sense of urgency. A water problem that is addressed in its early stages can be the game changer in preventing severe and costly issues in the future. No matter the size of the water intrusion, with enough time, it can build up to be a major hazard to your safety, your family’s safety, and/or your employees’ safety. In cases where the water intrusion cannot be seen, be vigilant and pay attention to the signs. If you detect any of the above signs, do not casually dismiss the issue. A seemingly minor symptom can be pointing to a serious problem.
