Crawl Space Moisture Control in Bay Area

Crawl space moisture has been plaguing homes in California since they were first built. As the space becomes increasingly humid, moisture will condensate on the surfaces in your crawl space, leading to serious problems in your home.

Most of the problems traditionally associated with damaged, rotting crawl spaces are due to basic flaws in the ways that crawl spaces were designed.

We offer free crawl space repair quotes in San Jose, Oakland, Fremon and many areas nearby. To schedule your free appointment, call or e-mail us today!

How Crawl Space Humidity Begins

When the frame of your home was first built, it was a large wooden box, with few, if any, holes in it.

Then came the other contractors. As plumbers, electricians, HVAC workers, and countless other professionals began to work in your home, they began to cut channels in your walls and floors. Pipes, wires, cables, ducts, and other things were passed through, and your home's construction was completed.

Then, over time, your home began to expand and contract. The once-tight seams began to warp slightly, and more crevices and openings appeared. There are a lot of openings between your first floor and your crawl space!

In your home, warm air rises, leaving through your attic and upper floors. As this happens, a vacuum is created on the lower floors. Air from the outside -- and from your crawl space -- is pulled upwards to fill the space.

If you have crawl space vents, they will also become part of the air movement in your home. As air is pulled out of the crawl space and up into the home, new air will be pulled in through these vents.

Here's the key point: If the air outside is wet or humid, then your crawl space vents are bringing in moisture.

What Crawl Space Moisture Does To Your Home

Crawl space moisture leads to all of the following problems in your home:

As humidity builds in your crawl space, it creates an ideal space for mold and rot to grow. As it does, all organic material in your crawl space will be damaged -- including wooden floorboards and support beams.

A rotting crawl space will begin to sag, creating uneven floors above. In some extreme cases, sections of the floor may even begin to cave in!

additionally, many pests (termites, carpenter ants, wood-eating beetles, crickets, et al.) love rotting, moldy wood. Your open vents will be an invitation for them to move in.

As mold and rot increase and animals begin to live (and die) in your crawl space, odors will begin to rise into your home along with the crawl space air. Mold spores are a known allergen, and they can significantly affect anyone in the home who suffers from asthma or allergies.

During the hot summer months, crawl space moisture will also increase your home's cooling bills. Have you ever seen water dripping from a window-mounted air conditioner? This is because a large part of the job of an air conditioner is to dehumidify the air it cools. Humid air is much more expensive to cool than dry air! And of course, that freezing cold winter air that enters through the crawl space vents isn't helping either....

Controlling Crawl Space Moisture

Mold & Mildew Alert!

Mold needs three important things to survive:

  1. Warmth
  2. Moisture
  3. Food

Of these, the easiest to control in your home is moisture.

Fortunately, controlling crawl space humidity is easy! At Clean CrawlSpace Inc., a crew of our crawl space contractors can usually install a moisture control system in less than a day.

We recommend starting by sealing those crawl space vents, then following up by installing a crawl space vapor barrier on the walls and floors. A dehumidifier is a great finishing touch, drying out the space and helping you to preserve your home.

At Clean CrawlSpace Inc., crawl space repair is our specialty, and we'd like to show you why we're the best. To help you decide which repairs are best for you, we offer free crawl space repair quotes to homeowners in our area.

We serve California, including Daly City, Concord, Redwood City, Berkeley, San Leandro, Vacaville, Santa Clara and many areas nearby. To schedule your free quote, contact us today!
