Tips for How to Get Rid of Moisture in Basement Areas

1. Fix the Slope Around Your House

If you’re wondering how to get rid of moisture in basement, you have to understand how it’s getting there in the first place.

One way it might be entering your home is from outside, either because of rain, snow melt, or your sprinklers.

You’ll need to check your property and see how the land slopes.

If it’s angled toward your home, then this means that rain, snow, or water from your yard is being directed into your basement.

That could lead to excessive moisture, dampness, and humidity, as well as mold growth.

To ensure that water doesn’t get into your basement and wreak havoc, the slope around your house should be angled so that water flows toward the yard or street and away from your property.

If you can gain access to topsoil or dirt and reslope the area around your house, this can solve a lot of your problems.

If not, getting this fixed will require a helping hand by a lanscape professional.

2. Place a Plastic Barrier on the Ground

Another way that water or moisture can get into your basement is up through the ground.

If you have a dirt floor in the basement, you might need to place a plastic barrier on the ground.

The moisture will still exist, but it won’t be able to penetrate the plastic, keeping your basement drier and less humid.

This is a super simple way for how to keep moisture out of basement if you do have a dirt floor. Other methods you’ll find can be much more complicated and unnecessary.

3. Use a Dehumidifier

If you’re asking how to reduce humidity in basement, then you should consider getting a dehumidifier.

This appliance works by pulling excessive moisture out of the air and collecting in a bucket or directing it down a drain.

If you’re looking for how to remove humidity from basement, this is your best option.

A good dehumidifier can pull gallons of moisture out of the air in a day, and this can help reduce the total amount of moisture in your basement.

4. Use an Air Purifier

In addition to a dehumidifier, you should also invest in an air purifier.

While this machine doesn’t necessarily remove water from the air, what it does do is filter out the harmful particles that are floating around in it.

High moisture content inevitably leads to mold and mildew growth.

And air purifiers can extract the mold spores out of the air and trap them inside a filter and/or kill these microorganisms so they don’t lead to health complications.

Moisture can also find its way into your basement through cracks or holes in the foundation.

The water can either come from the ground, rain, snowmelt, or sprinkler system.

When it comes to how to get rid of moisture in basement, check the walls and floor to see if there are any openings.

If you notice water staining, then this is an indication that moisture is getting into the area.

Small holes and cracks can be fixed with polyurethane masonry caulk, while larger issues will need to be fixed with hydraulic cement.

If you don’t want to handle this task on your own, you can always can in a professional for assistance.

6. Fix Leaking Windows and Doors

Not only are cracks and holes in your foundation a way for moisture to get into your basement, but leaking windows and doors can add to this problem as well.

Make sure the seals are tight and not worn or cracked. If they’re cracked or missing chunks, get them replaced. Otherwise, use high-quality silicone caulk to seal up the gaps.

7. Repair Plumbing Leaks

Leaking plumbing can be a common reason for why you have moisture or humidity in your basement and it’s a relatively easy fix for how to get rid of dampness in basement.

To determine if this is the culprit, examine the walls and ceiling for any signs of water damage.

Also look under and around any piping that runs through the basement. Check under cabinets too.

You may also hear dripping when in the basement and this could be another sign of water leaking into the space where you can’t see it.

Calling in a professional to fix plumbing issues is worth every penny. Or you can try to tackle these jobs yourself if you have the patience to try them.

8. Waterproof the Walls

Waterproofing your walls can be beneficial if you’re looking for a permanent solution for how to get rid of dampness in basement.

There are two ways to waterproof your walls:

  1. A professional can dig a trench around the basement wall, and then cover them with a waterproof material. If the moisture problem in the basement isn’t major, this will help with how to reduce humidity in basement.
  2. Another option is to paint the interior of your basement walls with a waterproof material. This is the more cost-effective choice for how to remove humidity from basement and one you can easily do yourself.

9. Insulate Cold Water Pipes

Since cold water pipes are colder than the environment around them, they’re commonplace for condensation to form.

To prevent this moisture from impacting your basement or increasing the humidity levels, consider insulating them with foam.

10. Extend Downspouts

If the downspouts on your home aren’t pushing water far enough away from your foundation, then when water runs off your roof, it could find a way into your basement.

When it rains or when snow or ice melts, this moisture has to go somewhere.

And you want to make sure that it’s not into your basement.

Extending your downspouts is a quick fix for this common problem.

The downspouts should extend at least six feet away from your house.

It’s also a good idea to check the slope around your home to ensure the water continues to flow away from your property and not back towards it.

When it comes to getting downspout extenders, you should be able to find these at retail stores or online and affix them yourself.

However, if you prefer to have assistance from a professional, you always have that option.
