8 Ways To Get Rid of Moisture In Your Basement For Good

Get Rid of Excess Humidity

Eliminating the sources of humid air will help to get rid of moisture in your basement.

• Seal leaky dryer vents with foil tape to prevent unwanted humid air from entering your basement. Don’t just use duct tape; it’ll eventually fall off.
• Add a vent fan to your basement bathroom and make sure your family turns it on during showers.
• Keep your basement windows closed during humid weather.
• And if you’re still getting condensation on cool surfaces, run a dehumidifier to lower the indoor humidity.

Install Insulation

One of the best ways to get rid of moisture in basement is to make it difficult for it to enter in the first place. Well placed insulation will help to cut down on condensation.

Pipes

Condensation dripping from cold pipes can contribute to basement water problems. Cover cold water pipes with foam pipe insulation to stop condensation. The foam insulation is inexpensive and easy to cut with scissors, so you can install this yourself.

Walls

Insulate exterior walls to prevent condensation. In cold climates, wall insulation in the basement also saves energy and reduces your heating bill. But don’t cover the walls with insulation if water is leaking in from outside; you’ll just create a potential mold problem.

Keep Water Away From the Foundation

If your basement leaks after heavy rains or after snow melts, your yard needs better drainage. It starts by making sure water is diverted away from your foundation may solve the problem. It’s common for the soil alongside your house to settle over time, creating a moat that collects runoff and directs it down your foundation wall and into the basement. Lawn edging and gravel along the foundation can make things worse.

Solve the problem by creating a 6-ft.-wide slope that drops about 4 in. away from the foundation. For extra insurance, cover the sloping soil with a layer of 6-mil poly. Then hide the poly with mulch, gravel or a layer of soil covered with grass. This will keep water from soaking in near the foundation.

Add Gutters and Extend Downspouts

If your basement leaks after it rains and you don’t have gutters, consider adding them. Gutters catch the rain and channel it to the downspouts, which direct it away from the house. Whether you’re installing new gutters or already have them, be sure the downspouts have 4- to 6-ft. horizontal extensions to move the water away from the house.

Plug Holes and Cracks in the Foundation

Holes and cracks in your foundation can let moisture and water seep into your basement. Plugging them probably won’t solve basement leaks, but it’ll help. Hydraulic cement works great for patching holes in a foundation because it can set up even under water, and it expands as it sets to seal the hole and lock the plug in place. Use a cold chisel or an angle grinder fitted with a masonry-cutting disc or diamond blade to enlarge the hole or crack into an inverted “V,” with the narrow part of the “V” on the surface of the wall. Then follow the package instructions for mixing and using the hydraulic cement.

Waterproof the Walls

Waterproof wall coatings that go on like paint fill the pores in the concrete or masonry walls and prevent water from leaking in. To be effective, these coatings must be applied to bare concrete or masonry walls. Start by removing loose material with a wire brush. Then clean off any white powdery “efflorescence” with masonry cleaner. Follow the safety and application instructions carefully.

A common mistake when using masonry waterproofing products is to spread them too thin. The goal is to fill every pinhole to create a continuous waterproofing membrane. Brush the coating in all directions to completely fill every pinhole. Add a second coat after the first dries.

Install a Drainage System

The best permanent fix to get rid of moisture in your basement is to install drainage tubing below the basement floor that’s connected to a sump basket and pump. You can install a system like this yourself, but breaking out the concrete floor, burying the tubing, and patching the floor is a lot of backbreaking work. So you may want to spring for professionals for this step, if you’ve got the budget.

Install Drainage Mats for a Warmer, Drier Floor

Plastic drainage mats, or dimple mats, allow air to circulate under the basement flooring and provide a moisture barrier. They also provide an insulating layer of air that separates the floor from cold concrete, reducing the potential for moisture damage from condensation or water vapor migrating through the concrete.at look like tile. Floating luxury vinyl floors connect with self-adhesive tabs or interlocking edges.
