Once fall rolls around, most of us focus on raking, sealing up drafts, and getting the yard ready for winter. But there’s another seasonal task that pays off all year: making sure water can drain away from your house. When drainage is working, you protect your foundation, basement or crawl space, siding, landscaping, and even indoor air quality. When it isn’t, small issues can quietly turn into expensive repairs.
The good news is you don’t need a complicated inspection to catch the most common trouble spots. Before the first leaves drop (and before gutters and drains start clogging), take a walk around your home and check these seven places where water should be moving away—not pooling, backing up, or soaking in.
1) Gutters: clean, intact, and able to move water
Gutters are the front line of drainage. Their job is simple: catch roof runoff and guide it to downspouts. When they’re blocked or damaged, water spills over the edge and lands right next to the foundation, which is exactly where you don’t want it.
What to look for:
• Leaves, seed pods, or roof grit building up in the troughs
• Sagging sections, separated seams, or brackets pulling loose
• Rust spots, cracks, or pinhole leaks (especially in older metal gutters)
• Stains or streaking on fascia boards and siding beneath the gutter line
Quick checks you can do: On a dry day, visually scan for debris and sagging. During a light rain, watch for overflow points—those are your clog locations or pitch problems. If a section holds standing water after the rain ends, the gutter may not be pitched correctly toward the downspout.
Why it matters: Overflowing gutters can saturate soil along the foundation. That moisture can find its way into basements or crawl spaces, contribute to musty odors, and increase the chance of cracking or shifting over time. Keeping gutters clear is one of the simplest ways to reduce water where you least want it.
2) Downspouts: extensions and discharge direction
Even perfectly clean gutters won’t help if the downspouts dump water right at the base of your house. Downspouts should carry water away from the foundation and release it where it can spread out and soak in safely—or flow to a proper drainage area.
What to look for:
• Downspouts that end right at the wall or only a few inches from the foundation
• Splash blocks missing, tilted, or buried
• Extensions that are crushed, disconnected, or aimed back toward the house
• Erosion channels carved into soil or mulch where water rushes out
Quick fixes: Reconnect loose joints and add or replace a downspout extension so water is released farther from the house. If an extension is constantly in the way, consider a hinged extension that flips up for mowing.
Why it matters: Concentrated roof runoff can dump a surprising amount of water in one spot. If that spot is near your foundation, it increases the risk of seepage and soil settlement. Directing discharge outward helps keep the ground around your home drier and more stable.
3) The soil slope along the foundation: grade that sheds water
The ground next to your house should slope away so rainwater naturally runs outward instead of collecting against the foundation. Over time, soil can settle, landscaping beds can be built up incorrectly, and foot traffic can create low spots that hold water.
What to look for:
• Puddles or consistently damp soil right next to the foundation after rain
• Mulch that looks washed out or displaced
• Soil level that has sunk, creating a “trench” along the wall
• Plant beds that are higher than the surrounding yard and trap runoff
What you can do: Fill low areas with soil and re-establish a gentle slope away from the house. Keep soil and mulch below siding and other wall materials so moisture isn’t held against them. If you’re adding soil, compact it lightly in layers so it’s less likely to settle again quickly.
Why it matters: A negative slope (ground tilting toward the house) invites water to press against the foundation. Even without a dramatic “flood,” that constant moisture can contribute to basement dampness, efflorescence, and long-term wear on foundation materials.
4) Window wells and basement egress areas: clear paths for runoff
If your home has basement windows below grade, window wells are another spot where water can collect. They often fill with leaves in the fall, creating a soggy, clogged pocket that holds water right against the window and foundation.
What to look for:
• Leaves, mulch, or soil piled up inside the well
• Standing water after rain
• Rusted or bent well walls pulling away from the foundation
• Cracked window frames or deteriorated seals
Maintenance steps: Remove debris regularly, especially as trees start dropping leaves. If you have well covers, confirm they sit properly and aren’t cracked or missing fasteners. For egress windows, make sure the lid and surrounding grading don’t funnel water into the opening.
Why it matters: Water sitting in a window well can seep through window assemblies or tiny gaps, leading to interior water damage and mold-friendly conditions. Keeping wells clear and discouraging runoff from entering them can prevent a very stressful surprise during a heavy rain.
5) Driveways, walkways, patios, and steps: hard surfaces that can send water the wrong way
Concrete, pavers, asphalt, and stone are great for living space and curb appeal—but they can also act like slides that steer water straight toward your foundation if they’ve settled or were installed with the wrong pitch.
What to look for:
• Cracks or separations where slabs meet the house
• Sections that have sunk, creating a low point near the foundation
• Water lines or algae growth along the base of the wall
• Puddles that form near steps, garage slabs, or patios
What you can do now: Clean out joints and gaps and monitor them during rain to see where water flows. If you spot water running toward the house, you may need to reseal joints, adjust edging, or consult a pro about lifting or re-leveling slabs. For minor issues, improving nearby grading and ensuring downspouts don’t discharge onto the hard surface can reduce the water load.
Why it matters: Hard surfaces can collect large volumes of runoff quickly. If that runoff is directed at your foundation, it can overwhelm the surrounding soil’s ability to absorb water, increasing the chance of seepage and erosion.
6) Yard drains, swales, and low spots: keep the “escape routes” open
Many yards have natural or intentional channels that guide water away—shallow swales, drainage ditches, or grated yard drains. These are easy to forget until they clog with leaves and the yard turns into a sponge.
What to look for:
• Grates covered in leaves or grass clippings
• Mud buildup, standing water, or slow-draining areas after rain
• Swales that have been flattened by mowing patterns or filled with mulch
• Water that now pools in places it didn’t used to
Simple maintenance: Rake and clear grates, and remove debris from swales. If you have a drain inlet, check that it isn’t buried by soil or landscape fabric. After cleaning, test with a garden hose (gently) to see whether water is moving as expected.
Why it matters: A yard drain or swale is only helpful if it stays open. When these routes clog, water spreads out and often finds the easiest path—frequently toward the lowest point near the house, a garage, or a basement entrance.
7) Garage thresholds and exterior door areas: stop water from sneaking inside
Garages and exterior doors are common entry points for water, especially during wind-driven rain or when melting snow refreezes and redirects runoff. Leaves can pile up in corners near doors and create little dams that hold water against thresholds.
What to look for:
• Leaf buildup along garage doors, side doors, and porch edges
• Worn door sweeps, cracked seals, or gaps at the bottom corners
• Settled concrete at the garage apron that pitches water inward
• Damp spots or staining on the garage floor near the door
What you can do: Keep the area swept and clear before and during leaf season. Replace worn weather stripping and door sweeps. If water consistently flows toward the garage, look at the surrounding grading, downspout discharge, and the slope of the driveway apron to identify what’s feeding the problem.
Why it matters: Even small amounts of repeated water intrusion can damage stored items, promote rust and mildew, and create slippery conditions. Addressing the flow and sealing gaps is usually cheaper than repairing water-damaged framing or finishing.
A quick rainy-day test (and what to write down)
If you want the fastest way to spot drainage issues, walk around your home during a steady rain (or right after). Bring an umbrella, keep a safe distance from slippery surfaces, and note where water is doing anything other than moving away.
Write down:
• Any spot where water overflows a gutter seam or corner
• Where each downspout discharges and whether water spreads out or trenches a channel
• Puddles that last more than an hour after rainfall ends
• Water flowing toward the house from a hard surface or landscaping bed
This short list becomes your to-do plan for the weekend, and it helps you prioritize what to fix first.
When it’s time to call in help
Some drainage improvements are straightforward, like cleaning gutters, extending downspouts, or regrading a small low spot. But consider getting professional input if you notice repeated basement seepage, large areas of standing water, significant slab settlement, or signs of foundation movement (such as widening cracks or sticking doors). A qualified contractor can help identify the source of the water and recommend solutions appropriate for your property.
One last fall reminder
Leaves are beautiful right up until they’re plastered over a drain grate or packed into a gutter elbow. If you take care of drainage before the first big drop, you’ll spend less time reacting to problems and more time enjoying the season. A little prevention now can keep your home drier, safer, and more comfortable through the wet months ahead.
