Vapor Barriers in the Crawlspace
Vapor Barriers in the crawlspace. They are simple, often overlooked, and really provide great benefits to the home and the homeowner. So let’s get into it!
Look at the big picture and you’ll notice that a fallen tree limb left on the ground will decay and begin to rot. You’ll also note that the wood trim in your bedroom, has a relatively low moisture content and is not rotting. So that’s a good starting point for thinking about crawlspaces. Crawlspaces most often are dirt floors providing access to the systems of the home. They are sort of in-between places, that are covered from the rain, but still exposed to the outdoor temperature and humid air of the south. These dirt floors are getting moist from the air and from the drainage around the home. And if something isn’t placed to stop that moisture from entering the air, then the wood subfloor and framing will absorb that moisture leading to decay or becoming inviting for wood destroying organisms.

But the great thing about vapor barriers is that they are very simple. In the most basic form, you just need a roll of 6mm plastic, which is available at all home improvement stores. Have someone roll this plastic out over the entire crawlspace, and you’re done. Simple! It is a messy job, often with little room to work, so I recommend hiring someone to do it except for the ardent do-it-yourselfers.
An added benefit is that having a crawlspace moisture barrier helps keep the musty old house spell out of your home, making it a major win for such a small improvement, especially when complemented with professional ac repair service, which ensures your home’s comfort and air quality remain optimal year-round. For an extra boost in air quality, consider a dual fuel hvac system. According to experts like air conditioning service columbus oh, these systems use both electricity and natural gas, providing efficient heating and cooling, ultimately contributing to a healthier indoor environment.
Schedule regular heating and ac repairs to maintain the efficiency of your hvac system. Also, to ensure good-quality air comes from the unit, it needs to be regularly checked and ask for help from cooling and heating services in Olympia WA. If you notice any issues with your furnace, it’s best to have it inspected and repaired by a professional furnace repair technician.
A cautionary note: I can’t tell you how many homes I’ve seen where the trash can is filled with an old dirty plastic moisture barrier, and the crawlspace is now a bare dirt floor. Often, if I get the opportunity to ask, the answer is that the plastic was dirty, and the homeowner or handy man thought it was a good idea to remove it to “clean up the crawlspace.” Little did they know how much work that plastic was doing 365 days a year.
Does your home have a vapor barrier? Does it cover the entire crawlspace? Does your home suffer from musty odors after rainfalls? What’s the moisture level on your subfloor? These questions are answered in every home inspection I do.
