How To Deal With A Damp Crawl Space

A damp crawl space is more than just a minor annoyance, in fact, it can be a major safety hazard when you factor in that dampness lead to structural damage and mold growth. Unfortunately, damp crawl spaces are common household issues, and they usually arise either out of a freak accident (like say a burst pipe) or a failure on the home owner’s part to protect their crawl space from moisture. Either way, a damp crawl space has to be dealt with in a timely manner, in order to prevent mold growth or major structural rot. If you discover that you have a damp crawl space, here are the steps you should take to deal with it.

Identify what’s causing the dampness

First thing’s first, before you try to start drying out your crawl space, you need to determine what exactly is causing the dampness in the first place. There are a number of issues that can lead to damp crawl spaces, and it is not always easy to determine what the exact cause is. Sometimes the cause is obvious, for example, a leaky pipe or a lack of a vapor barrier. But sometimes the cause is less obvious, for example, damp crawl spaces can be the result of gutters not taking rain water away from the house. Whatever the cause, it is important you identify and fix the cause of the dampness first.

Drying out the damp crawl space

When it comes to actually drying out the damp crawl space, the first thing you are going to want to do is remove all debris from the crawl space. Any boxes or materials that are in the crawl space should be removed. Leaving things in the crawl spaces will not only make the drying process take longer, but those items could be infected with mold; so it is important that you make sure you deal with them appropriately. It’s also worth noting that if you are actually going into the crawl space, you should maybe get a protective mask, even if there isn’t mold yet, you are probably going to want to avoid breathing in all the dust and debris in the crawl space.

The next step is to inspect all the insulation and see if it is damp. Damp insulation should be stripped and replaced, as it is a fertile breeding ground for mold. Depending on the type of insulation, you may be able to dry it out and put it back, but certain types of insulation lose their effectiveness after getting damp; so it is probably better to just replace it entirely.

Next check for mold, if you find it, you’re going to have to deal with the mold in two ways. You can call a professional, or you can do it the old fashioned way by using bleach and a scrubber to get rid of the mold yourself. Either way, it is important that you get rid of mold before it can spread and cause any actual issues.

Finally, in terms of actually drying out the crawl space, the best way to go about it would be to use a strong dehumidifier. You can find specialty dehumidifiers that are specifically for drying out large spaces, such as a crawl space, and you may want to invest in one of those. If you think the dampness may come back again in the future, you may want to consider investing in a dehumidifier with a pump, so that it can continually keep your crawl space dry.

Why A Wet Crawl Space Can Cost You A Lot Of Money

To many people, a wet crawl space may not seem like a big deal. And a lot of people may be tempted to put off dealing with a wet crawl space because they don’t want to spend the money to properly dry out the crawl space. The truth is though, if you don’t deal with a wet crawl space quickly, you are going to have to spend a lot more money down the line to deal with all the problems associated with a wet crawl space. Here are just a few examples of problems that you will have to deal with if you don’t react quickly to a wet crawl space.


A lot of different kinds of pests (termites, ants, rats, mice, etc.) love damp, dark spaces to set up their nests. So a wet crawl space tends to attract these various types of pests. Not only can these pests do a lot of damage to your house (anyone who has ever had a serious termite or rat infestation can attest to that), but you are also going to have to pay a professional to get rid of them. Professional pest removal is both time consuming and expensive, so if you can deal with a wet crawl space before pests get into it, you will save yourself a lot of money and time.


If you let a wet crawl space go unattended, you are almost certainly going to end up with a serious mold infestation. Now depending on the level of mold, it may not be too expensive to deal with it. If there is only a little bit of mold, then you can probably take care of it yourself with a scrubber and some bleach. But, if there is a lot of mold, then you are going to have to call a professional mold remediation service, and that is going to cost you. If you deal with a wet crawl space quickly, you can avoid having to deal with a serious mold infestation.

Structural Damage

If you don’t respond quickly to a wet crawl space, you run the risk of things within the crawl space, like joists, pipes, ductwork, wiring, etc., becoming damaged due to prolonged exposure to moisture. Wooden structures can begin to rot and things like ductwork and pipes can begin to even rust. These issues are going to need to be fixed by licensed professionals, which will cost you a lot of money.

Damaged Insulation

If your crawl space is wet, then there is a strong possibility that any insulation in the crawl space may also be wet. Wet insulation is fairly useless. This means that the energy efficiency of your house is going to go down and you are going to have to spend even more to heat or cool your house. It’s not a huge cost, but it can add up over time.

So, don’t delay dealing with a wet crawl space, you are only going to end up costing yourself more money in the long run.

How To Get Rid Of Water In Your Crawl Space

It is a good idea to know how to deal with water in your crawl space. Even if you have taken all the proper precautions, your crawl space can still flood because of matters outside of your control (like a burst pipe, or a large amount of rain). Now, if your crawl space has water in it, the first step is always to identify why there is water in the crawl space; if it is something that you can fix, you should do so before actually removing the water in the crawl space. But when you finally get around to actually removing the water from your crawl space, here are the steps you need to take.

Get a pump

If there is a large amount of water in your crawl space, you are going to need to pump it out. While heavy duty pumps are somewhat expensive, you should be able to get a relatively cheap, low volume pump from your local hardware store (in most cases, these types of pumps will be able to easily get rid of most of the water in your crawl space). Operating pumps a pump is fairly simple; just set it up outside the crawl space, run the hose into the crawl space, and then run the discharge hose to an area outside your house, where the water can be safely discharged. If your crawl space floor is made of dirt, be careful where you place the pump because the dirt may clog it.

Using a wet vacuum

The pump will probably not be able to remove all the water, so in order to remove the last little bit of water from your crawl space, try using a heavy duty wet vacuum. Depending on the amount of water left over, you may have to make multiple trips to empty out your wet vac, so plan accordingly

Drying out the dampness

Once the water has been removed from your crawl space, you need to dry out the crawl space to prevent mold from growing. There are two methods for doing this, first, you can buy an industrial dehumidifier. This is the most effective route. The other method is to set up a fan system to dry out the crawl space. If you do plan to use a fan to dry out the crawl space, make sure it’s an industrial fan. To make sure the crawl space has been thoroughly dried out, make sure to leave the dehumidifier or fan running overnight.

Preventing future incidents

After the crawl space is dried out, you are going to want to look into how to prevent water from getting into the crawl space in the future. The best way to go about this is to get a sump pump installed (if you already have one, and still have issues with water, you may want to consider getting a second one installed). Sump pumps are generally pretty effective at keeping water out of places like basements and crawl spaces. They are a must have if you live in a flood-prone area.

What It Is And Why It May Be One Of The Most Important Appliances In The House

For people who have a basement or crawl space that suffers from excessive moisture or who live in an area prone to flooding or receiving large amounts of rain, a sump pump can end up being one of the most important appliances in any home.

What are they and how do they work?

Sump pumps are appliances that are installed in basements or crawl spaces and are designed to remove water. The way they work is quite simple. Large holes are specifically built under the basement or crawl space. The water drains into these holes. Inside the holes are special devices called “float switches,” which are used to detect the level of water in the hole. As the amount of water rises, the float switch is activated. The sump pump then starts moving water out of the hole, and through the discharge pipe. Sump pumps run entirely on electricity.

You can probably already guess why sump pumps are so important; flooding is a huge problem for some homes, and sump pumps help prevent basements and crawl spaces from being ruined by flooding. At the same time, sump pumps also help prevent other issues too, for example by preventing moisture from seeping into basements and crawl spaces, sump pumps help protect against mold and other fungi, which can cause both health problems and structural damage.

How to get one?

Sump pumps can be found easily in almost any hardware store. Installation can range from being very easy to being a bit trickier. If you already have a sump pump hole built in your basement or crawl space, and you are good with your hands, then you could probably install the sump pump yourself. Otherwise, it is best to call a licensed professional to come install the sump pump. You want to make sure the sump pump installed correctly, since if it isn’t, you could end up paying for it by having your basement or crawl space flood.

Regular upkeep

It is also worth keeping in mind that sump pumps require pretty regular upkeep. First off, sump pumps generally do not give off any warning signs if they fail, so it is necessary to occasionally check the motor and make sure the sump pump is still running. A common trick is to empty some water directly into the hole and see if the sump pump starts up.

As with any pump, the sump pump needs to be regularly cleaned, since there is a good chance that rocks and other debris may get stuck in the pump and reduce its effectiveness.

Motor failure is also an issue to watch out for, especially if the sump pump is being forced to work overtime because of a sudden increase in rainfall. It is a good idea to keep a backup power source close by in case the sump pump’s motor fails.

Finally, the float switch can also get stuck, which will prevent the sump pump from working correctly. So it is a good idea to do regular checks to ensure that the float switch is working correctly.

Waterproofing Your Crawl Space?

Here Are Some Easy Methods To Keep Your Crawl Space Water Free

It is important that if you have a crawl space, that you keep it water free. Letting water get into your crawl space is an easy to way to get mold, pest infestations, and structural damage. Now the most obvious method for keeping your crawl space dry is to install a vapor barrier. Vapor barriers are one of the most effective ways of keeping your crawl space dry, but there are some other methods that homeowners can try if they want to keep their crawl spaces bone dry.

Check your gutters

Believe it or not, keeping your gutters clean and in working order can help prevent water from getting into your crawl space. When gutters are clogged, water spills over the gutters and can land near your house’s foundation, where it can find its way into the crawl space. This is especially noticeable during periods of extended rainfall. So, if you want to waterproof your crawl space, try making a habit of cleaning out your gutters (homeowners should clear their gutters regularly anyways).

Likewise, you will also want to make sure that your gutter’s downspouts are working properly. Downspouts should be extended enough so that the water that comes out isn’t dumped close to the foundation. So, if you want to keep your crawl space free of water, make sure your downspouts are extended far enough and if they aren’t, fix them as quickly as possible.

Issues with landscaping

In order for water to properly drain away from your house, your yard should slope away from your house. This way, when it rains, water flows downhill, away from your house. Sometimes during the building process, the grading can be done improperly, which leads to water flowing towards your house’s foundation, where it can seep into the crawl space. In order to fix this, you are either going to need to hire professional landscapers, or take on the project yourself (but only if you have some experience with home landscaping).

Get a sump pump

Sump pumps are appliances that are installed in basements and crawl spaces to help prevent the buildup of water. Holes are dug and filled with float switches. As water fills the holes, the switches are activated and the sump pump will suck the water out and prevent it from overflowing into your crawl space. If you choose to get a sump pump installed, be aware that they require regular maintenance (they can get clogged with debris, and the float switch can often get stuck). If you live in an area that gets heavy rainfall, you should seriously consider investing in a sump pump (or maybe even two), they are great ways to keep water out of your crawl space.

As stated earlier, the most effective way to waterproof your crawl space is to invest in a vapor barrier; but if you feel that a barrier is not enough, then these are some other methods you can try to keep your crawl space free of water.

Why You Need To Install A Crawl Space Vapor Barrier

Many people probably aren’t familiar with the term “vapor barrier,” and even if they had heard the term before, many probably couldn’t tell you what they did or why they were important. Many probably don’t know that vapor barriers play a key role in protecting their homes from major issues like mold infections, structural damage, rusting ducts, and other household problems. If you are one of those people who doesn’t know what vapor barriers do and why they are important, then don’t worry, because you aren’t alone.

What do vapor barriers do?

Water vapor naturally arises out of the ground. Simply put, a crawl space vapor barrier’s job is to keep the water vapor out of your crawl space. It may sound like a simple job, but it is actually very important.

Why is it important?

You may be wondering why it is important to keep water vapor out of your crawl space. There are a couple reasons why.

First off, when water vapor gets into your crawl space, it causes mold. Because of the stack effect (the process by which air travels up from the bottom of your house, out through the top), much of the air you and your family breathes starts out in the crawl space. If you have mold in the crawl space, then the air because infected with dangerous mold spores and will carry an extremely unpleasant scent. But, decreasing the air quality isn’t the only danger mold poses. Certain types of mold can get into wooden structures and start to cause rot. Structural damage caused by mold is a major issue that homeowners have to be on the lookout for.

Water vapor does more than just cause mold though. For example, water vapor can begin to collect and potentially cause issues with ducts or pipes contained in the crawl space. Plenty of people have ductwork or piping running through their crawl space, and this is all very susceptible to rust if you don’t take steps to prevent water vapor from seeping into the crawl space. The same logic applies for any wiring that you have going through the crawl space. Obviously, it goes without saying that you don’t want to have anything electric mixing with water.

One last point to mention is that excessive moisture caused by water vapor tends to attract various types of pests. Rats, mice, termites, etc., are attracted to dark, damp environments; so a crawl space that isn’t adequately protected is more prone to infestation.

How can you get one installed?

If, after reading this, you desperately want a crawl space vapor barrier you have two options. First off, if you have a good amount of skill when it comes to handiwork, you can try installing a vapor barrier yourself. There are plenty of do-it-yourself guides on the internet that can help you install the vapor barrier yourself. The second option (and the recommended one) is to simply call up a professional and have them install one. If a barrier isn’t installed correctly, it won’t work. So, it is important that the job is done correctly.

How To Get Rid Of Crawl Space Mold

Crawl spaces are fertile breeding grounds for mold. If you haven’t taken steps to ensure that your crawl space is moisture free, then there is a good chance that your crawl space, may have a mold infestation. Thankfully, mold is relatively easy to get rid of if you know what you’re doing. But it should be noted, that if there is a lot of mold, then it is better to just call a licensed professional to deal with the mold problem. But if there is only a moderate amount of mold, you can deal with it yourself.

Get all the necessary equipment

The first thing to do is to gather all the equipment you are going to need to get rid of the mold. Make sure you have proper clothing; when cleaning mold you want to make sure you have clothing that covers your entire body (overalls are a good example). You also want to make sure you have eye protection, and that the crawl space is well ventilated, to prevent you from breathing in large amounts of mold spores. Finally, make sure you have all the tools you need to actually get rid of the mold (a scrubber, a mold removing solution, a soda blaster, etc.).

Find the source of the mold infestation

Your next step is going to be finding the source of the mold. Mold doesn’t just grow on its own, there has to be a way for moisture to be getting into your crawl space. So it is important that you identify the source of the moisture. There are a lot of possibilities (it could be a leaky pipe, improper ventilation, etc.), so make sure you do a thorough check of your crawl space. Before dealing with the mold, you need to deal with the moisture. A common method is to use a dehumidifier to dry out the crawl space, then moving in to deal with the mold.

Dealing with the mold

Once you have gotten the moisture dealt with, you can move onto actually removing the mold. The traditional method is to use a mold killing solution, such as bleach, to remove the mold. What you do is spray the solution on the moldy surfaces, let the solution seep in for a couple hours, and then proceed to manually scrub the mold away (make sure to regularly wash your scrubber, this prevents the mold from being spread around). This is of course extremely tedious, but it does work quite well.

Another possible method is to use abrasive blasting to remove mold. Abrasive blasting requires a specialized machine, which blasts things like dry ice particles against the mold infected areas. It is a bit harder and more expensive than the traditional method of mold removal. But the upside to this method is that removes mold quicker and more effectively. Also, abrasive blasting is able to get rid of mold in areas that would be hard to reach with a scrubber (like corners).

Some Ways To Do It

Moisture in a crawl space is, to put it mildly, very bad. Moisture, along with other factors like inadequate ventilation, leads to the growth of mold. Mold in a crawl space is dangerous for two reasons. First off, certain types of mold can get into the wood and cause structural damage by causing the wood to rot. Secondly, mold in the crawl space is more hazardous than mold in other places in the house, because air rises from the crawl space, meaning that spores and odors from the mold will be carried up into other areas of the home. For these reasons, it is essential that the amount of moisture in your crawl space be kept under control. If you are stuck wondering what you can do to prevent moisture from getting into your crawl space, here are some methods to help keep crawl space moisture under control.


Dehumidifiers are typically used to dry out a crawl space after flooding or a major leak. But, they can also double as a permanent way of keeping your crawl space moisture free. Simply figure out how large the dehumidifier needs to be; if you aren’t sure what size you need, simply measure out your crawl space and consider how serious the moisture issues are, then go from there. It is also worth noting that if you do plan to regularly use a dehumidifier, you should get a model that has a built-in drainage system, so that you aren’t constantly emptying out the dehumidifier.

Ensure adequate ventilation

One of the best ways of keeping crawl space moisture under control is to ensure that your crawl space is properly ventilated. The rule of thumb when it comes to crawl spaces is that for every 150 sq. feet of crawl space there should be at least 1 sq. feet of ventilation. Generally, you are also going to want to keep both the crawl space itself clear and the area outside the clear to ensure proper cross ventilation. So, make sure your crawl space is reasonably free from clutter and debris. Also, make sure you clear bushes and other debris outside the house, to ensure good airflow. If you take steps to ensure that your crawl space is always properly vented, then you should never have problems with moisture.

Installing a fan

If you are seriously concerned about moisture getting into your crawl space, then you might want to consider having a crawl space fan system installed. These fans can help move air throughout the crawl space, which does help fight against moisture. But, before installing a fan system in your crawl space, you should know that not all the relevant experts agree that fan systems help keep a crawl space dry. Some experts assert that fan systems encourage the growth of moisture by drawing humid air into the crawl space. Ultimately experts are divided, so before making any decisions, consult with the relevant experts and do some research.
