Most homeowners do not spend much time thinking about the crawl space.<\/p>\n

Then somebody goes under the house.<\/p>\n

A plumber sees dark growth on the floor joists. An HVAC technician notices wet insulation. A home inspector finds a musty crawl space. Or you open the access door yourself and immediately notice that earthy, damp smell.<\/p>\n

Sometimes there is standing water.<\/p>\n

Sometimes the soil is dry when you look, but the wood overhead tells a different story.<\/p>\n

PuroClean provides professional crawl space mold cleanup in Millville, NJ<\/strong> for homes dealing with mold on floor framing, damp insulation, groundwater intrusion, plumbing leaks, condensation, high humidity, and other moisture problems beneath the home.<\/p>\n

The mold matters.<\/p>\n

But the better first question is:<\/p>\n

Why is the crawl space wet enough for mold to keep growing there?<\/strong><\/p>\n

A Crawl Space Is Not Just Empty Space Under the House<\/h3>\n

It may feel separate from the rooms where you live, but a crawl space is part of the building.<\/p>\n

Above it may be your kitchen, living room, bedrooms, plumbing, ductwork, insulation, subfloor, and the wooden framing carrying the floor.<\/p>\n

Below it may be exposed soil, a concrete or masonry floor, foundation walls, drainage pathways, plumbing lines, and mechanical equipment.<\/p>\n

That makes the crawl space a meeting point for several different moisture sources.<\/p>\n

When one of those sources gets out of control, the first thing you see may be mold on the wood.<\/p>\n

But the wood did not create the water.<\/p>\n

Where Is the Crawl Space Moisture Coming From?<\/h3>\n

Before deciding how to clean the mold, figure out how the space became damp.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n

Sometimes there is one obvious answer.<\/p>\n

Sometimes there are three smaller problems working together.<\/p>\n

That is common in crawl spaces.<\/p>\n

South Jersey Humidity Changes the Crawl-Space Conversation<\/h3>\n

One of the easiest assumptions to make is that a damp crawl space simply needs more outside air.<\/p>\n

Sometimes ventilation is part of the design.<\/p>\n

But opening vents is not a universal cure for moisture.<\/p>\n

During humid New Jersey weather, the outside air itself may contain a large amount of moisture. If that air moves into a cooler crawl space, relative humidity can rise and condensation can develop on cold surfaces.<\/p>\n

That is why you can have a crawl space with no obvious pipe leak and still find damp joists, sweating ductwork, wet insulation, or mold growth.<\/p>\n

The real question is not:<\/p>\n

\u201cAre the vents open?\u201d<\/em><\/p>\n

It is:<\/p>\n

\u201cWhat moisture-control strategy was this crawl space designed around, and is that strategy actually working?\u201d<\/strong><\/p>\n

A Dirt Crawl Space Can Produce Moisture Without Looking Flooded<\/h3>\n

This surprises homeowners.<\/p>\n

The soil does not need to have puddles on top of it to contribute moisture to the crawl space.<\/p>\n

Moisture in the ground can migrate upward and evaporate into the crawl-space air.<\/p>\n

That is one reason ground vapor barriers are commonly used in crawl spaces with exposed soil.<\/p>\n

A properly installed ground cover can reduce the amount of soil moisture entering the space.<\/p>\n

But the plastic is not magic.<\/p>\n

If rainwater is pouring underneath the house, a pipe is leaking, or groundwater is collecting around the foundation, simply putting plastic over the dirt does not solve the entire problem.<\/p>\n

What If There Is Already Plastic on the Ground?<\/h3>\n

Look at the condition of it.<\/p>\n

A ground cover that exists and a ground cover that is actually doing its job are not necessarily the same thing.<\/p>\n

Look for:<\/p>\n
