Crawl Space Barriers Keep Your Home's Foundation From Rot

In most homes, the crawl space floor is the dirt upon which contractors built the house. When the soil gets saturated, water accumulates in the crawl space. Moisture from condensation also contributes to the problem.


A crawl space barrier controls the humidity in your crawl space and keeps it from causing problems in your house. The plastic barrier traps the water vapor underneath and keeps it from reaching your insulation.


This system helps avoid mold, mildew, and other common moisture-related problems. The barrier may be up to 20 millimeters thick, depending on environment.


If your home has a crawl space underneath, you may notice that moisture tends to gather around the ductwork, wiring, and plumbing typically found there. Even though you probably don't enter your crawl space much, paying attention to what is happening is still essential.


If left untended, damp environments can breed mold, insects, and other things that may damage the structure. If you notice a sour smell in the area, or if the air smells terrible every time you enter, you may need a crawl space vapor barrier system.


The earlier you get the problem treated, the more problems you can avoid.


DJG Insulation LLC is a licensed insulation contractor with over a decade of experience serving the Toms River, NJ area. We can install a vapor barrier system in your crawl space that will protect your home from moisture damage for years.

When to Check Your Home's Crawl Space

An excellent time to check your home's crawl space is after heavy rain; if you see water accumulating in puddles or creating mud, that's a sign of trouble. You may need a barrier to keep that water from reaching your home. Other signs that you need a crawl space barrier include:


  • Infestations of rats, termites, or other insects that thrive in damp environments: These creatures love a water source and can destroy your home's infrastructure if you let them set up housekeeping in your crawl space. These pests pose a health hazard through the spread of disease and damage to your home.
  • Decaying wood or rusting metal: Often a sign that moisture is present frequently and for long enough periods to damage the building materials. Replacing damaged components, such as plumbing and wiring, can be expensive, time-consuming, and even dangerous.
  • Mold or mildew growing on the walls or floor: Indicates that the crawl space is staying too moist. Though the problem may start in the crawl space, it could also invade the interior of your home.
  • A damp or musty smell always present when you enter the crawl space: Another sign that you need a moisture barrier. While the scent may be most prominent after a rain, the crawl space also smells unpleasant in dry weather.


DJG Insulation can help you determine where the moisture is coming from and how you correct the problem. The answer may be crawl space vapor barriers. Though crawl space vapor barrier is the most common term you see when reading up on the topic, they may also be referred to as air space sealers or crawl space encapsulation.


These are all terms for a system that controls moisture in the crawl space. You should contact us immediately if you see any signs in your home's crawl space. Waiting can cost you thousands of dollars in repairs if you procrastinate until problems are more advanced.

How Crawl Space Barriers Help Overall Energy Costs

When you have a crawl space vapor barrier installed, the plastic material helps reduce the amount of air that flows up from the ground. The atmosphere in the crawl space becomes "conditioned," similar to how your HVAC system heats and cools the air inside your home.


The temperature in the crawl space will stay about the same as indoors. For example, when the heat inside warms the floors in the winter, the crawl space also stays warmer. The result is that you use less energy to keep the home comfortable.

Basement Insulation Available in Many Forms

At DJG Insulation, we offer several types of basement insulation, ranging from cellulose and fiberglass batts to spray foam insulation. For unfinished basements, we can use foam board and batts, and for finished basements, we highly recommend spray foam insulation for it's effortless application.

  • Cellulose and Fiberglass Batts

    Both perform the same functions. It’s standard to add cellulose to existing cellulose or fiberglass to existing fiberglass when talking about a basement space. Because fiberglass is not moisture resistant, both of these products have disadvantages, including issues with mold and mildew. 


    However, both of these products are endorsed by many professionals and can provide adequate insulation to a basement.

  • Basement Insulation R-Values

    The climate you live in and your home's design contribute to deciding which R-value your insulation should be. There are many tools for calculating the R-value required for your home. The Department of Energy has an excellent tool based on your zip code.


    Since the climate in New Jersey varies drastically from season to season, New Jersey requires a higher R-value than warmer states like California or Arizona. Recommended R-values for your basement in New Jersey are usually R-19 for electrically heated homes and R-11 for homes that run on natural gas.

  • Benefits of Insulating Your Basement

    The main benefits of insulating your basement are the substantial energy and money savings you experience. Your savings will depend on the HVAC system you use, how the rest of your home is insulated, and the type of use you get out of your basement.


    Depending on what you plan to use your basement for, the benefits of basement insulation could include the following:


    Reducing Energy Consumption

    Insulating your basement walls will provide your home with a protective layer to combat the temperature fluctuation in New Jersey's changing climate. New basement wall insulation will aid in temperature regulation and keep your home warmer in the winter and cooler in the summer. You will also be able to reduce the number of your energy bills due to running your HVAC system at lower frequency and intensity.


    Lowering Moisture Content

    Improperly insulated basements can be subject to moisture accumulation condensation. These issues can lead to harmful mold, mildew, and fungi growth in basement walls over time. These problems can eventually destabilize your home's structure. Mold and mildew can also leave you at risk for serious health issues if they are not taken care of immediately. If you properly insulate your basement walls, you can lower the chances of these situations occurring.


    Increasing Home Comfort

    Insulating your basement walls can significantly improve not only the comfortability of your basement but also your entire home. Basement insulation can be highly effective in preventing heat loss in the winter and heat gain in the summer. Insulating your basement can effectively avert temperature fluctuations otherwise common in homes with poor insulation. Insulating your basement walls will almost certainly help regulate your home's temperature.


    Preventing Freezing Pipes

    In a climate like the New Jersey winters, freezing pipes are always a concern in the wintertime. Basements with proper insulation do not encounter this issue. If the water pipes in your basement are not insulated, they could be at risk of freezing on a frigid day. Avoid this issue entirely and protect your basement.


    Today, people are converting their basements into entertainment centers and family gathering sites. Whether hosting a group for the big game or watching a movie with the family, having a livable environment in your basement is crucial to having a good time.


    Believe it or not, your basement is commonly a significant source of your home's energy loss. Not to mention, without up-to-date insulation, your home may experience buildups of moisture, mold, and mildew, all of which lead to a hazardous environment for your family.


    As it turns out, insulation is the most cost-effective way to maintain your desired temperature and environment. Insulation in your basement walls helps lock in coveted conditioned air while blocking out outdoor temperatures, all while keeping your home's energy system functioning at its highest efficiency.


    The optimal insulation will provide your basement with a waterproof barrier to help prevent irritating pest infestation and improve your basement air quality. Contact us for a full-service home energy audit today to determine if your basement requires new insulation.

I have had really, really bad luck with contractors, to the point where I was very hesitant to hire anyone to do anything. I needed the insulation in the attic of my home replaced, and I seriously considered doing it myself because of my previous experiences. I thought I'd get some quotes to see my options.

Devin's quote was very fair, and he even gave me a few options based on how we wanted to proceed. I had a lot of questions, and he patiently answered all of them.

He arrived exactly when promised. His crew was efficient and clean; they took photos of the progress to show me. Devin was so knowledgeable, flexible, patient, and just lovely that he gave me hope for future contractors. Thank you, Devin!
