Crawl Space Repair Problem Signs: Finding and Replacing Wet Crawl Space Insulation

Wet crawl space insulation is one of the worst crawl space concerns you may never have heard of. You probably know on some level that wet insulation is bad for your crawl space, but did you know that it could be worse for your crawl space than no insulation? Do you know all of the ways wet crawl space insulation can impact your home? Here’s what you need to know.

How Can You Discover Wet Crawl Space Insulation?

The process of fixing wet crawl space insulation starts with knowing the insulation is even there. Here are a few of the ways you can find out about your wet crawl space insulation. 

  • Warning Signs of Wet Crawl Space Insulation

Wet crawl space insulation can come with a variety of warning signs. When you have wet crawl space insulation, it’s typically because of an underlying problem like a leak or a flood you never really cleaned up after. That can lead to these secondary problems, which can clue you into a crawl space water issue:

  • High humidity
  • Mold and mildew
  • Higher electric bills
  • More difficulty regulating temperature

These aren’t all directly indicative of wet crawl space insulation, however. Many of them are indicative of a water problem, which can impact the crawl space’s health in many ways, including crawl space insulation concerns. This can be a useful way to know whether you’re dealing with general crawl space water issues, however.

  • Get a Yearly Inspection from an Expert

These secondary signs aren’t enough to diagnose your crawl space. If you want to do that, you’re going to have to talk to a crawl space repair expert. Doing a yearly inspection can be a great way to stay up to date on all the potential problems your crawl space can have.

Some homeowners, however, skip these yearly inspections. Rather than knowing how important the yearly inspections are to a crawl space’s health and well being, they assume that it’s doing just fine. A yearly inspection is one of the few ways you can feel completely certain you know your crawl space is healthy. 

  • Do Regular Inspections Yourself

A crawl space expert will have the best insight into what makes up a healthy and unhealthy crawl space, but doing regular inspections can help you point a crawl space expert toward potential problem areas. That’s because you live in your home. You can note when something is changing, even if you don’t know whether it’s changing for better or worse.

When you do get your yearly crawl space inspection, consider asking that expert for tips and tricks on how to inspect your home. Remember to set aside some time, ideally once every month to three months, to go through with it, or you might end up continuing to forget about your crawl space needs.

What’s the Impact of Wet Crawl Space Insulation?

Sure, wet crawl space insulation happens. However, what type of impact does it have? Most homeowners don’t really know. Here’s what you should know about how it impacts your home. 

  • In the Crawl Space

Wet crawl space insulation will have a profound and obvious impact on the crawl space itself. The water in the wet crawl space insulation tends to invite mold and mildew because it’s hard for it to dry out for good. Instead, it retains this area of wet insulation that can be seriously difficult to get rid of and has high enough humidity to encourage mold and mildew growth.

The crawl space can also have other problems. Most commonly, you’ll have high levels of humidity, which can correspond to issues with your floor joists and problems with the insulation process itself. The crawl space will be much less healthy if you don’t manage your wet insulation problems.

  • In the Rest of Your Home 

These problems will also travel throughout the rest of your home; they’re not just going to stay in the crawl space. Many homeowners hypothesize that up to 50% of the air in your home could be from your crawl space in one way or another. Do you want low-quality, humid crawl space air in the rest of your home when you’re having issues with crawl space moisture?

This can cause similar problems in the crawl space and the rest of the home. Additionally, because water is a conductor, it completely erases the usefulness of the insulation in the first place. You might end up with worse insulation in the crawl space as opposed to no insulation at all.

  • Throughout the Property 

Because crawl space insulation problems typically stem from some other sort of problem, you may experience other issues you weren’t expecting because they share a common problem. The wet crawl space may not be impacting the rest of the property in an extremely direct way.

For example, insulation problems can happen if you have a lot of hydrostatic pressure from too much water around your crawl space. The fact that there’s too much water can reflect in the rest of the property. If you’re not willing to address the base problem, which is the influx of property water, you might end up with even more concerns.

FAQs About Wet Crawl Space Insulation

It’s possible to have wet crawl space insulation and not know it. Many homeowners have wet crawl space insulation and don’t realize it. It’s especially common for there to be a little bit of wet insulation without you being aware of the problem. Here are a few of the reasons that it’s so easy to have wet crawl space insulation without knowing it.

  • “Insignificant” Crawl Space Concerns

When you have wet crawl space insulation, it’s very common for the insulation problems to feel relatively small and not significant. For example, you might just have slightly more humid areas in your home or floors that seem a little bit “bouncy.” However, you should still address these problems even if they don’t seem very significant.

Part of the reason you need to tackle these “insignificant” crawl space concerns is that they may escalate out of sight or be the result of more severe issues that you can’t easily spot. This may be the tip of the iceberg. Tackling them at this “insignificant” phase can be very beneficial, so you can spend less money and time on fixing them.

  • Recognizing the Impact After You Fix the Insulation

Once you take the steps to fix your wet crawl space insulation, you might realize they’ve been impacting how much you pay in electrical bills and your indoor humidity levels. For some homeowners, fixing wet crawl space insulation can seriously reduce their bills. This impact won’t be obvious until you’ve fixed the problem, however.

You’ll have to fix your crawl space insulation problems to realize how important your secondary problems can be. Moving forward with your crawl space insulation fixes is the best way to repair the problem. Plus, when it comes to issues like high electrical bills, getting an expert in to fix the problem can pay for itself.

Crawl space insulation seems to “attract” moisture, which can confuse some homeowners. It’s not that there’s anything special about crawl space insulation, but instead that its very makeup seems to make it much easier for it to become full of moisture.

  •  It’s Supposed to Remain Dry

Since crawl spaces are meant to stay dry, they’re very sensitive to moisture. When crawl space insulation gets wet, it’s likely to stay wet, and that means it’s fairly unlikely to have crawl space insulation that dries itself out even after months of moisture.

This causes an unfortunate problem in many crawl spaces. Your insulation may start to have moisture problems even when no moisture seems to be present, or it may harbor things like mold and rot, which can escalate into bigger problems. All it needs is one-time contact with water, and it may remain damp for weeks. That means it will seem to “attract moisture” long after moisture has left the area.

  • The Absorbency of the Insulation Lends Itself Well to Moisture

Insulation is extremely light and typically uses very moisture-averse materials. That makes it very absorbent, which means that if any moisture gets on the insulation at all, it will absorb into it. That can itself create serious problems in the future. Essentially, because the area needs to stay dry, moisture can sink into the insulation over time.

The usefulness of your crawl space insulation tends to have a direct link to its ability to absorb moisture. That means the best crawl space insulation needs a moisture-averse element to help avoid this. Essentially, you’ll probably need a crawl space dehumidifier in your crawl space to ensure there isn’t enough humidity to impact your crawl space insulation.

There are many reasons you might experience crawl space insulation concerns with moisture. There are many potential reasons that it’s important to know more about the history of your home so you don’t have to worry about wet crawl space insulation.

  • Floods and Standing Water

Whenever your crawl space has problems with a flood or standing water, you might have wet crawl space insulation. This is one of the more obvious reasons that you could have problems with water in the crawl space. Insulation may be able to hold in heat or cold, depending on your needs, but it will also hold in water if it’s exposed.

If you’ve had any sort of flooding or plumbing leakage problems in your crawl space, you need to assume that there are going to be serious problems with your crawl space insulation. It’s extremely common for this to escalate into worse problems.

  • Generally High Humidity

It’s not just about obvious standing water in your crawl space. Even too-high levels of humidity can cause serious concerns with wet crawl space insulation. If the humidity levels get too high, the moisture in the air can condense into water droplets, especially if you have problems with open crawl space vents [add link], which allow the humidity levels to go crazy throughout the space.

If you do have high levels of humidity, you’re almost certainly going to end up with condensation. This crawl space condensation can escalate into mold, rot, or other forms of deterioration. It only takes a few droplets of condensation to start eating through the crawl space insulation, which can be a problem that lingers for months.

Some homeowners take the approach that they only need to address home problems if they’re extremely serious. As you might imagine, they couldn’t be more wrong. Ignoring wet crawl space insulation isn’t the right move for several reasons.

  • Wet Insulation Is Useless

The most obvious reason you can’t ignore wet crawl space insulation is that it’s useless. Wet insulation no longer works as insulation and it may even be more harmful than effective. Water tends to allow temperatures to move even more easily between areas, which means that your crawl space might be less insulated with wet insulation than with none at all.

If you have a wet crawl space, replacing that insulation will be your first step to having a healthier home. This will help prevent related issues, such as severe water damage, bad air quality, or harm to the surrounding wooden structure. Getting someone else to help you with the wet insulation will be your best option if you want to insulate your space correctly.
