The short answer

Clean Gutters and Downspouts

Clogged gutters cause water to spill over the edge and pool around your foundation. That standing water can seep into basements or crawl spaces over time. Clear leaves, twigs, and other debris at least once a year, ideally in late fall after the leaves drop.

Check the downspouts for blockages by running a hose through them. Make sure they direct water at least a few feet away from the foundation. If you live in Arlington, keep a note of where your main shutoff valve is located in case you ever need to stop water flow quickly.

Inspect Your Roof and Flashing

Roof leaks often start as tiny cracks or loose shingles that let water sneak in. Once a year, look for missing or damaged shingles, rusted flashing, and gaps around vents or chimneys. Use binoculars from the ground if you are not comfortable walking on the roof.

If you see any issues, a roofer can handle repairs. Also check the attic for stains, damp insulation, or daylight coming through the roof boards. Catching a small leak early prevents rot and mold from spreading through your home's structure.

  • Look for curled or cracked shingles
  • Check vent and chimney flashing for gaps
  • Inspect attic for water stains or damp wood
  • Trim overhanging branches that can damage shingles
  • Verify gutters are securely attached to the roofline

Test Your Sump Pump

If your home has a sump pump in the basement or crawl space, test it once a year. Pour a bucket of water into the pit and confirm the pump turns on and drains the water. A stuck float switch or a burned-out motor can leave you with a flooded basement during a heavy rain.

If the pump does not work, an electrician or a plumber can help with repairs or replacement. Keep the pit clean of debris that might jam the float. Also check the discharge line for cracks or loose connections that could let water leak back in.

Check Plumbing and Water Heater

Inspect visible pipes under sinks, around toilets, and near the water heater for small drips or corrosion. Tighten loose fittings, but be careful not to overtighten. A slow leak can waste water and damage cabinets or flooring without you noticing for weeks.

Drain a few gallons from your water heater each year to remove sediment that can cause rust and early failure. Look at the base for pooling water or rust spots. If the heater is more than a decade old, consider having a plumber check the tank and connections.

Seal Windows, Doors, and Foundation

Cracks around window frames, door thresholds, and the foundation let rainwater enter your home. Once a year, walk the exterior and check for gaps in caulk or mortar. Reapply exterior-grade caulk where it is cracked or missing, and repair any foundation cracks you find.

Pay special attention to the basement walls and the sill plate where the house meets the foundation. If you notice water seepage after heavy rain, a water damage inspection can help you understand the source. Sealing these gaps is a simple task you can do yourself with a caulking gun.

  • Inspect caulk around all exterior windows
  • Check door thresholds for gaps or rot
  • Look for cracks in the foundation walls
  • Ensure exterior grade caulk is used for outdoor sealing
  • Test your shutoff valve to make sure it turns easily

Frequently asked questions

How often should I clean my gutters?

At least once a year, but twice is better if you have many trees nearby. Clean them in late fall after leaves drop and again in early spring after winter storms. If you notice water spilling over during rain, clean them sooner.

What is the most common cause of home water damage?

Plumbing leaks, such as a burst pipe or a worn-out water heater, are common causes. Roof leaks and foundation seepage also rank high. Regular inspections of these areas can catch problems early before they spread.

Can I do these maintenance tasks myself?

Yes, many tasks like cleaning gutters, sealing gaps, and checking pipes are DIY-friendly. For roof work, sump pump repair, or water heater issues, you may need a professional. If you are unsure, a water damage inspection can point out hidden risks.
