Checklist Of Leak Sources On Walls

Cars submerged at Dallas Love Field parking garage after heavy rainfall

When looking for leaks look very carefully for even the smallest hole or crack and look at the undersides of things even if means you have to get down on your knees.

Retrofit Measures for Cracks and Holes: If you find any of the above conditions you should seal these joints. You can use single applications of caulk for small cracks up to about ¼” wide and multiple applications for cracks up to about ½” wide. Foam available in spray cans at hardware stores and home supply stores can be effective for filling larger holes. However, these foams deteriorate within a year when exposed to sunlight . Consequently, if you use foam you will need to coat it with a urethane caulk to protect it from sunlight. Holes in stucco can be repaired using a plastic like material that is available at some paint stores. It comes in caulk tubes and bucket sized containers. It has the advantage that it can be tooled to look something like stucco. For best functional results push it into cracks and for cosmetic results spread it over as narrow an area as practical. Only use caulks suitable for outdoor applications and for more information about Caulks and Sealants, click on Caulks and Sealants. Caulks used for interior paint work are not suitable for outside use because they will degrade, shrink, and become hard and brittle. They will be ineffective within a year.

One Last Thing You May Want To Look At Is The Grading Around The Garage As Well

Just like with your house, if the grading is sloped toward your garage rather than away from it, you will want to work on fixing it so that it does not drain in doors.

In addition to the above and other solutions listed in this article, remember to take steps to ensure your garage maintains a cool and dry environment by buying a de-humidifier, allowing air to circulate, and keeping the temperature controlled.

Prevention And Permanent Solutions

The best way to deal with water coming in under the garage door is to prevent it from happening in the first place.

Water can cause all sorts of damage. It can seep into cracks in the garage floor, freeze, and cause bigger cracks. It can also damage items stored on the floor or freeze in the Winter making the floor slippery It can lead to mold growth when it gets into cracks and crevices.

But prevention is often easier said than done.

Inspect your drainage system

The first place to look is the general drainage system. For example, are your downspouts draining properly from your home?

In some cases, downspouts that have overflowing underground drains can back up water at your garage door faster than it can flow away from your home. This allows the water to come under the garage door and onto the garage floor.

If your downspouts drain into the yard, make sure that they drain a minimum of 6 from the house.

Driveway grading

In order to drain water off your driveway, your driveway should have a natural slope to allow water to flow away from your garage.

Driveway grading and leveling is a permanent solution and may not always be feasible in the short term financially or if there is no slope to work with. It can be quite costly.

If there is not adequate slope, then having a professional install a channel drain where the driveway meets your garage floor is also another great option.

How To Dry Out A Wet Crawl Space

Flooded garage from heavy rain storm

Once you have removed the water from your crawl space, it is essential that you dry out the area thoroughly. Never simply allow the space to air dry. Since wood will soak up moisture at an alarming rate, and cool concrete surfaces retain water much longer than most other materials, a significant amount of moisture will likely remain even after you have removed the puddles of water.

A dehumidifier is extremely effective at removing excess moisture from a damp crawl space. A high-quality machine will eliminate moisture in the air, drastically reducing the chances of mold or mildew development.

How To Stop Water Leaking Through Your Garage Door

  • Using an adhesive, apply threshold seal to your clean concrete garage floor. This will create a ramp that lets the water slide away and prevents it from entering into your garage. You can get a threshold kit from almost any DIY store such as B& Q or online.
  • Replace your garage doors bottom seal with a larger one. However, please do keep in mind that there are a number of different seals out there, and you want to be sure you buy the right one. You will need to know what kind of channel you have usually this will be single or double.
  • If your garage floor has a slope, then you will need to get yourself an adjustable aluminium retainer. This item is u-shaped and will fit at the bottom of your garage door so it can be adjusted to fit the slope of the floor.
  • If you have no luck with the solutions stated above, this could be due to the fact that the rainwater is coming in from elsewhere, such as the roof, windows. If this is the case, you will need to install a drain inside your garage.
  • Can Water Come Up Through A Concrete Garage Floor

    Yes, this is what happens when your garage floor was installed without a vapor barrier or was laid down improperly.

    Because concrete has a porous nature, when moisture underneath it has nowhere else to go, it can seep into the concrete itself and even cause it to crack if there are no cracks there already.

    If you want to check to see if the moisture on your garage floor is due to sweating or water from underneath it, you can try taping down a pad over a wet area after absorbing the moisture.

    • If it is no longer wet the next day, then the moisture likely came from condensation.
    • If it is still wet then the moisture is likely from ground water being pushed up to the surface.

    Water In Garage After Rain

    Gary Ennis Jr. lives in what appears to be suburban Woodhaven, Michigan. But when it rains, he’s got water in his garage. Here’s his story:

    “I have a two-car detached garage that has water come in at the floor when it rains.

    I have installed a drain system around the outside but still have water coming in. I removed the plywood over the walls and found that on top of the cement floor they have stacked red bricks around the perimeter one layer high.

    On top of that is the sill plate. Water is coming into the garage between the bricks and under the bricks. I can actually remove the bricks from the center of the walls. How can I fix this problem?”

    Here’s the outside of Gary’s garage:

    Oh my, look at how high the soil and grass is against the garage. It should be at least 9 inches LOWER! Photo credit: Gary Ennis Jr.

    Well Gary, I can sure see why you have a problem.

    Whoever built your garage put it into the ground about one foot too deep. If I’m to assume the brick and siding I see in your photo starts on top of the garage slab, then I can see why the water seeps into your garage.

    The building code, which is a set of MINIMUM standards, states that the ground around a structure should be 6 inches LOWER than the top of the foundation. Your slab is considered the foundation in this case.

    What To Do When Water Is Seeping Up Through Your Concrete Garage Floor

    Stopping water from seeping up through your garage floor can be fixed depending on whats causing it.

    If the water is coming in through cracks in your floor, then it can be fixed using concrete filler you can find in your closest home improvement store.

    Simply make sure the crack is clean before putting any filler in, smooth out the area with a knife, and leave it to dry over night.

    If the problem is not due to any noticeable cracks, you can use a concrete sealant to keep the water from coming up to the surface. This product can also be purchased either at a local home goods store.

    Before using it you will want to make sure your garage floor is as clear of as many objects as possible.

    Why Is Standing Water So Bad

    Standing water doesnt seem like a big issue at first, but when you think of all the different things that come with standing water, it becomes a serious issue. Standing water becomes a breeding ground for mosquitoes, regardless of where the water may be.

    If the standing water is on soil, mosquitoes wont be your only problem. Standing water can cause muddy spots on your lawn, make soil unstable, and also become the main reason of muddy tracks in your home.

    Floodwater and standing waters can be dangerous and can make you vulnerable to infectious diseases, chemical hazards, and injuries. Protect yourself and your loved ones from the risks brought by floodwater.


    In recent years, the CDC has sent out advisories to homeowners, warning them of the dangers of standing water. Getting rid of standing water is one of the only ways to curb the spread of pests that carry diseases like West Nile, Zika, and malaria.

    Standing water near the foundation of your home is the leading cause of leaks in a basement. The water drains along the side of your basement walls, and when it freezes, the water will expand and could crack your foundation or basement walls.

    Heres a good video that explains how stagnant water breeds mosquitoes to give you a better idea of how that works.

    Garage Floor Sweating And Condensation

    Flooding in residents parking garage, P1 level  115 Hillcrest Ave

    If it does look like your floor is sweating, this is likely due to condensation on your garage floors.

    While you will of course want to get rid of this sweating effect, it is not due to something inherently wrong with your garage floor.

    This sweating phenomenon happens due to the fluctuations in temperature and air moisture in your area.

    When warm, moist air comes into contact with your cool concrete garage floor, the moisture will cool down and begin to condensate, causing it to turn into liquid and gather as water on the floor.

    Though a garage floor sweating is not an all too uncommon problem, it is still one that you will want to take care of as soon as you can.

    The moisture accumulating on your garage floor can cause a number of problems including:

    • Wet and slippery floors
    • Increases humidity of the garage
    • Causes metal items in your garage to rust
    • Can eventually cause a breakdown in your concrete flooring

    Dips In The Garage Floor

    The concrete floor of a garage can drop or settle with use.

    The movement of a heavy vehicle and the settling of the ground underneath can cause an uneven garage floor. This creates low or sloped spots for water to settle into.

    Water may also pool if the garage floor was not poured by a machine and at a graded slope.

    Often, older garages will have a slightly uneven surface with dips and bumps that are small but will hold water in place.
