Fall Waterproofing Maintenance: Preparing Your Home for Winter

Leaves are part of fall, but they do not belong in your gutters.

Clogged gutters can overflow during rain, sending water directly alongside your home instead of carrying it away. When water repeatedly collects near the foundation, it can contribute to difficult soil and moisture conditions around your basement.



After most of the leaves have fallen:

• Remove leaves and debris from gutters.
• Check that water can move freely through each downspout.
• Look for loose, damaged, or disconnected sections.
• Make sure downspouts direct water away from the foundation.
• Watch where the water goes after it leaves the downspout.

The last point is easy to miss.

A downspout may technically carry water away from the roof while still depositing it in a low area where the water flows back toward the foundation. Look at the entire drainage path, not just the gutter itself.

Look at the Grading Around Your Foundation

Walk around your home after a rainfall and pay attention to where water collects.

Ideally, the ground surrounding your home should encourage water to move away from the foundation rather than toward it.

Look for:

• Low spots next to the foundation
• Areas of standing water
• Soil that has settled near foundation walls
• Landscaping that traps water against the home
• Downspouts emptying into poorly drained areas
• Erosion that may have changed the grade

If you regularly notice puddles near your foundation after storms, there may be a drainage issue worth addressing before winter.

For properties where surface drainage alone cannot adequately manage water, a professionally designed drainage solution may be appropriate.

Inspect Your Foundation for Cracks

Fall is also a useful time to walk around your foundation and look for changes.

Pay attention to both the outside of the foundation and accessible foundation walls inside your basement.

Look for:

• New cracks
• Existing cracks that appear larger
• Horizontal cracks
• Stair-step cracks in masonry
• Cracks showing signs of moisture
• Bowing or leaning basement walls
• Areas where previous repairs appear to have changed

A crack does not automatically mean your home has a serious structural problem. Concrete and masonry can crack for several reasons.

What matters is why the crack formed and whether movement is continuing.

If a crack is changing, accompanied by wall movement, or allowing water into your basement, having it evaluated can help you understand whether you are dealing with a waterproofing concern, a structural concern, or both. You may be interested in foundation crack repair.

Check Your Basement for Signs of Moisture

Do not limit your fall inspection to obvious puddles.

Basement moisture can show up in several ways, and some signs are much easier to miss than standing water.

Walk around your basement and check for:

• Damp foundation walls
• Water stains
• Musty odors
• Recurring wet spots
• White, powdery deposits on masonry
• Moisture around cracks
• Dampness near the wall and floor joint
• Condensation
• Unusually humid conditions
• Signs of water around basement windows

Pay particular attention to areas where you have experienced leaks in the past.

If your basement only becomes wet during heavy rainfall, it can be helpful to inspect it during or shortly after the next substantial rain. That can make it easier to identify where moisture is appearing.

Test Your Sump Pump Before Winter

If your home depends on a sump pump, do not wait for the next major storm or snowmelt to find out whether it is working.

Fall is a good time to test it.

Check the sump basin and make sure it is not filled with debris that could interfere with operation. Test the system according to the manufacturer's instructions and confirm that the pump activates and removes water as expected.

You should also check where the discharge line exits your home.

Look for:

• Blockages
• Visible damage
• Loose connections
• Water discharging too close to the foundation
• Sections where water may remain trapped
• An outlet that could become blocked by leaves, snow, or ice

Cold weather introduces an additional concern because water remaining inside exposed discharge piping can freeze. A blocked discharge can prevent a functioning pump from moving water out of the basin.

If you are unsure whether your existing sump system is ready for winter, Foundation King can help evaluate it.

Keep Sump Pump Discharge Areas Clear

Testing the pump itself is only half the job. The water also needs somewhere to go.

Inspect the outdoor portion of the discharge system before freezing weather arrives. Make sure leaves, landscaping, debris, or other obstructions are not blocking the outlet.

During winter, keep an eye on this area after snow and ice accumulate.

You want discharged water to move away from the home without immediately collecting alongside the foundation. You also want to reduce the chance of the discharge becoming obstructed when temperatures drop.

If you notice that your sump pump is running but the water level is not dropping as expected, turn your attention to both the pump and its discharge path.

Inspect Basement Window Wells

Window wells can collect leaves, sticks, soil, and other debris throughout the year.

When drainage around a window well becomes restricted, water may collect against the basement window instead of draining properly.

During your fall maintenance:

• Remove leaves and debris.
• Check for standing water.
• Inspect the window for visible gaps or damage.
• Look for evidence of previous leaks.
• Make sure any existing drain is not visibly obstructed.
• Check the condition of window well covers, if present.

If you notice water staining or recurring moisture around a basement window, do not assume the window itself is the only problem. Drainage conditions around the well may also need attention.

heck Your Crawl Space for Moisture

If your home has a crawl space instead of a full basement, it should be part of your fall waterproofing routine too.

Crawl spaces are easy to ignore because you may rarely enter them. That can allow moisture problems to develop unnoticed.

Look for signs such as:

• Damp soil
• Standing water
• Condensation
• Musty odors
• High humidity
• Moisture on building materials
• Deteriorated or displaced moisture barriers

A damp crawl space can be difficult to manage with small maintenance changes alone, especially when moisture is consistently entering from the ground or surrounding environment.

Crawl space encapsulation is one option designed to help separate the space beneath your home from surrounding moisture.

Do Not Ignore Signs of Previous Water Intrusion or basement humidity

A basement or crawl space can feel damp and develop musty conditions even when there is no obvious leak. Cold surfaces can also contribute to condensation as indoor and outdoor conditions change.

If your lower level consistently feels damp, consider monitoring the humidity rather than relying only on how the room feels.

A dehumidifier may be useful when excess humidity is part of the problem. However, it should not be used as a substitute for repairing an active water leak or drainage problem.

A dry basement today does not necessarily mean last spring's leak has resolved itself.

If you had water in your basement earlier in the year, fall gives you an opportunity to investigate before another season of rain, snow, freezing temperatures, and eventual thawing.

Look at the area where the water previously appeared.

Fall Waterproofing Checklist

Before winter arrives, walk through this checklist:

• Clean leaves and debris from gutters.
• Check downspouts and where they discharge.
• Look for low spots near the foundation.
• Inspect foundation walls for new or changing cracks.
• Check the basement for dampness, stains, or musty odors.
• Test the sump pump.
• Inspect the sump discharge path.
• Clean debris from basement window wells.
• Inspect the crawl space for moisture.
• Pay attention to basement humidity and condensation.
• Check patios and other concrete for drainage toward the house.
• Revisit areas where water entered earlier in the year.
• Schedule an evaluation for recurring or unexplained moisture.

Prepare Your Basement this fall with Foundation King

Fall maintenance cannot prevent every basement water problem, but it can help you catch concerns while you still have time to address them before winter.
