Wet basements smell bad and reduce the value of your home. Unchecked basement moisture can damage floors, walls, and roofs.
Clearing gutters and redirecting gutter water can cure some wet basements. If the problem comes from surface water, seepage, or municipal storm drains, you must be more aggressive.

What Causes a Wet Basement?
Rainfall and the melting of snow are the two primary sources of water that are typically found in basements. Even a small storm can trigger a deluge. For instance, a home with a roof that is 1,500 square feet in area will shed 1,000 gallons of water for every inch of precipitation that falls. In more difficult situations, the issue is rising groundwater, which may even be being fed by a spring that is buried underground. Once water begins to pool around the perimeter of your foundation, it will eventually seep inside through any gaps, joints, or porous material that it can find.
Here are eight strategies to keep water out of your basement.
Add Gutter Extensions
Add plastic or metal gutter extensions if downspouts dump water less than 5 feet from your house.
Extensions aren't a good long-term solution if you'll trip over them or run over them with a lawnmower. Permanent underground drain pipe moves large amounts of gutter runoff far from your house.
You can plug cracks around plumbing pipes with hydraulic cement or polyurethane caulk for less than $20.
Plugs work when water oozes through a hole from surface runoff or wet soil. If water comes up through the floor or at the floor-wall joint, it's groundwater, and plugs won't work.
Restore the Crown
If the gutters are working and you've plugged obvious holes, but water still dribbles into your basement or crawl space, surface water isn't draining away from the house as it should.
Your house should sit on soil that slopes 6 inches over the first 10 feet in all directions.
The foundation settles over time. Shovel and dirt can rebuild it. One cubic yard of water-shedding clay-loam mix costs $30 (plus delivery) and covers 57 feet of foundation.
Building up the crown could bring soil, rot, and termites too close to your home's siding. Safe distance is 6 inches. Create a berm or swale to redirect water away from your home.
Landscapers can build small berms for a few hundred dollars. Larger projects don't benefit from berms because too much soil must be moved. Dig a $1,000 swale. Berms and swales become attractive once landscaped.
Repair Footing Drains
Hydrostatic pressure pushes water up from the ground and into basements where walls meet the floor.
First, check whether footing drains were installed to carry water away from the foundation. (Look for a manhole, drain, or cleanout pipe capped above the basement floor.)
Unclog drains with a garden hose by opening the cleanout. A plumber with an auger can do it for $600.
Install a Curtain Drain
Install a curtain drain if you don't have footing drains to divert water from your house.
Curtain drains are shallow trenches filled with gravel and perforated pipe that intercept water uphill of your house and carry it down the slope.
If the drain passes through trees or shrubs, switch to solid pipe to prevent root clogging. $10-$16 per foot.
Pump the Water
If subsurface water can't be stopped, it must be channeled.
Cut a channel around the floor's perimeter, chip out the concrete, and insert perforated pipe. The pipe drains to a sump pump in the basement's low spot.
In an unfinished basement with easy access, an interior system costs about $3,000. It's a good choice if your yard has mature landscaping that digging would destroy.
Waterproof the Walls
Interior drainage systems remove water but don't waterproof walls. A French drain relieves hydrostatic pressure, and exterior waterproofing protects the foundation.
It requires excavating around the house, but it may be the best solution if your foundation has gaps. It keeps mess and water outside, which is ideal if you don't want to gut a finished basement.
Your yard may be damaged, and you may need to remove decks or walkways.

Diagnose the Water Problem
Two sources provide basement moisture. Indoor humidity condenses on cold surfaces, like water droplets on a cold drink on a humid day. Outside water or vapour is the other. Rainwater, melting snow, or groundwater can seep into your foundation. Water can leak through cracks or enter porous walls as water vapour. Tape aluminum foil to your basement wall and inspect it a few days later. High indoor humidity is indicated by moist foil. Moisture behind foil indicates wall leakage. Here's how to finish a basement.
Get Rid of Excess Humidity
Eliminating humidity sources helps dry out a basement. Seal leaky dryer vents with foil tape to prevent basement humidity. Duct tape will fall off. Make sure your family turns on the vent fan in the basement bathroom when showering. Humidity makes basement windows foggy. Run a dehumidifier if you still get condensation on cool surfaces.
Cold pipe condensation can cause basement flooding. Foam pipe insulation prevents condensation on cold water pipes. Foam insulation is cheap and easy to cut.
Basement Leak Repair: Insulate Basement Walls
Wall insulation prevents condensation. Basement insulation saves energy and lowers heating bills in cold climates. If water is leaking in from the outside, insulating the walls could cause mold. Another basement spot to insulate.
Foundation Leak Repair: Plug Holes and Cracks in the Foundation
Foundation holes and cracks let water into the basement. Plugging them will help stop basement leaks. Hydraulic cement can set up underwater and expands as it sets to seal holes and lock in plugs. Use a cold chisel or angle grinder with a masonry-cutting disc or diamond blade to enlarge the hole or crack into an inverted "V" Mix and use hydraulic cement as directed.
Waterproofing materials applied like paint fill wall pores to prevent water leakage. Effective coatings require bare concrete or masonry walls. Wire-brush loose debris. Using masonry cleaner, remove any white powdery "efflorescence." Carefully follow application and safety instructions. Too much product is spread when waterproofing masonry. To create a continuous waterproofing membrane, fill every pinhole. Fill every pinhole with coating. After the first dries, apply a second.
How to Stop Basement Flooding: Install a Drainage System
Installing drainage tubing below the basement floor and connecting it to a sump basket and pump fixes chronic basement leaks permanently. Breaking out the concrete floor, burying the tubing, and patching the floor is backbreaking work. Basement materials cost $600 to $1,000. Professional installation for a standard-sized basement costs $3,000 to $8,000.
Install Drainage Mats for a Warmer, Drier Floor
Plastic drainage mats or dimple mats provide a moisture barrier and air circulation under flooring. They provide an insulating layer of air between the floor and cold concrete, reducing moisture damage from condensation or water vapour migrating through the concrete.
How to Stop Basement Flooding: Install a Sump Pump
Basement drainage is dirty, backbreaking work, but not difficult. With our experts' help, you can do a great job draining your basement. Do-it-yourself pays off: Professional basement drainage costs $5,000 to $8,000 (120 linear feet of drain tile). Materials and tool rentals cost less than $1,500. Here's the whole process.
How to Keep Water Away From House Foundation: Inspect and Take Notes
Check the foundation's surrounding soil. A 4-foot level, tape measure, and notepad are needed. Sketch your house and yard on a notepad. Check the slope around your foundation with a level. Look for sunken soil, garden beds with protruding edging, and sloping ground. Draw arrows on your sketch to show the slope. This step helps you develop a water-redirection plan.
How to Keep Water Away From House Foundation
Keeping water away from your foundation may prevent basement leaks after heavy rains or snow melts. Over time, the soil around your house settles, creating a moat that directs runoff into your basement. Lawn edging and gravel can make it worse. Create a 6-foot-wide slope that drops 4 inches from the foundation. Cover the sloping soil with 6-mil poly. Cover poly with mulch, gravel, or grass-covered soil. This prevents foundation water damage.
How to Keep Water Away From House Foundation: Add Gutters and Downspout Extenders
If your basement leaks when it rains, add gutters. Downspouts direct rain away from the house via gutters. Make sure the downspouts have 4- to 6-ft. horizontal extensions to move water away from the house.
How to Stop Water Seepage in your Basement
One of the most common problems in homes that have basements is water seeping inside and pooling on the floor. Several things cause a basement to get wet. Wet basements usually occur after heavy rains or during the winter months. In many cases, especially in older homes, there is not a foolproof answer to repair the problem. Several solutions are available to reduce the amount of moisture that comes into your home.
Examine the walls at the points where water can be seen entering the basement. Determine if the water is along a single wall entirely underground, along multiple walls or on one side of the house.
Examine the walls of the foundation for any signs of cracks. During the months in which the walls are dry, apply a construction-grade epoxy to the cracks in order to seal them. Caulking gun work is required to apply the epoxy. To form a strong bond, work the epoxy into the fissures using as much pressure as possible.
To stop water from pooling next to your home and causing damage, repair or replace any gutters that are broken. Because of the problems that they cause with drainage, gutters are frequently the primary cause of the issue. Installing splash pads made of cement under your downspouts will help direct water at least five feet away from your home's foundation.
Make it so that the land slopes away from the exterior foundation of your house. Put dirt up against the exterior wall of the basement so that it slopes downward at a rate of two inches for every foot. In order to prevent water from pooling near the foundation of your home, you should create a gentle slope away from it.
A layer of waterproofing should be applied to the interior of the walls of your basement. The waterproofing should be sprayed on in an even application. Maintain a distance of at least 10 inches from the walls of the basement while spraying in a side-to-side motion until the wall is completely covered. Spray the paint on the walls one at a time. Allow it to dry completely for two to three days before spraying another wall. In order to guarantee a strong connection, apply a waterproofing spray during the dry months.

If nothing else works, your last resort is to contract the services of a professional to inject an external waterproofing around the surface of your foundation. The waterproofing prevents water from penetrating areas of the ground that were previously open to it.
In this blog, we covered everything there is to know about water coming into your basement through various cracks and crevices.

FAQs About Basement Waterproofing
Apply a masonry waterproofing product to the walls
Seal/coat the interior of the walls with a suitable masonry waterproof product. When the paint dries, the sealant forms a watertight bond to stop water from seeping through. This is how you can waterproof your basement walls from inside.
Ideally, it is best to waterproof the exterior walls of a basement during the construction of a building. Newer construction mandates this procedure because of many state and local building code requirements, but many older homes may not have any exterior waterproofing in place.
The exterior waterproofing process includes excavation of soil surrounding your home and repairing the leaks using a powerful sealant. Interior basement waterproofing systems are considered better and more effective in preventing wet basements.
Most basement leak repairs, regardless of whether they are performed on brick, cement block, or concrete foundations, can be performed from the inside or the outside of the home. If you have a poured concrete foundation, both interior and exterior waterproofing repairs can be effective in preventing a wet basement.
To sum up, Basement Waterproofing timelines can vary depending on what needs to be done. As a general rule, the projects should be encased within 3 days, many times much less time than that. Most of our repairs are done within a day. It is when we have the larger projects that the timeline can be extended out 2-3 days.
