The short answer

Clear Gutters and Downspouts

Leaves and twigs pile up fast in fall, and clogged gutters send water spilling over the edges. That overflow pools around your foundation and can seep into a basement or crawl space. Before the heavy rains start, climb up and remove debris from every gutter and downspout. Use a trowel or gloved hands to pull out the muck, then flush the system with a garden hose to check for blockages.

Extend downspouts so water discharges at least six feet from your foundation. If a downspout is short, attach a flexible extension or a splash block to direct flow away from the house. Check that the ground slopes away from the foundation by at least six inches over ten feet. This simple grading fix prevents water from pooling against walls and finding a way inside.

  • Clean gutters twice in fall, once early and once after leaf drop.
  • Use a hose to test downspout flow and spot clogs.
  • Install gutter guards to reduce debris buildup.
  • Check for low spots near the foundation and fill them with soil.
  • Make sure downspout extensions are secure and not disconnected.

Test Sump Pumps and Drains

A sump pump is your first defense against basement flooding, but it only helps if it works when needed. Pour a bucket of water into the sump pit and watch the pump turn on and drain. If it runs slowly or not at all, clean the intake screen and check the float switch. Replace a failing pump before a storm hits, not during one.

Also check floor drains in your basement or garage for clogs. Remove any debris or covers and pour water down to confirm it flows away. If you have a backwater valve, inspect it and make sure it operates freely. These small checks take under an hour and can save you from standing water and costly cleanup.

Know Your Shutoff Valve

If a pipe bursts during a flood, the first step is to stop the water flow. Find the main water shutoff valve for your home, usually near the water meter or where the supply line enters. Test it once a year to make sure it turns easily. If you live in Kirkland, keep the valve location written down and share it with everyone in the household.

Also know where your gas shutoff valve is, in case flooding damages appliances. Do not turn off gas unless you smell a leak or are told to do so by the utility. For electrical safety, learn how to switch off power at the main breaker. This knowledge helps you act quickly when water is rising.

Protect Vulnerable Areas

Basement windows and door thresholds are common entry points for floodwater. Apply caulk around window frames and install covers or shields if you expect heavy rain. For doors, check the seals and replace worn weatherstripping. If you have a sump pump discharge line, make sure it is not blocked and that it directs water away from the house.

Store valuables and electronics off the floor in basements and garages. Use plastic bins instead of cardboard boxes, and raise them on shelves or pallets. Move hazardous materials like paint or fuel to a high shelf to prevent spills. These steps reduce damage and make post-flood cleanup simpler.

Make a Flood Response Plan

Flooding can happen fast, and a clear plan helps you act without panic. Decide who is responsible for shutting off water and gas, and where everyone will go if water enters the home. Keep important documents in a waterproof container and store it in an accessible spot. Charge your phone and keep a flashlight with fresh batteries near the shutoff valves.

If water does enter, do not wade into it if there is any chance of electrical hazards. Turn off power at the breaker only if it is safe to do so. For significant flooding, contact local water damage pros to handle extraction and drying. Acting quickly reduces the chance of mold and structural issues.

Water damage does not wait

Water keeps spreading into floors and walls, so it is worth acting early. Calls are answered 24/7.

Frequently asked questions

How do I know if my sump pump works?

Pour a bucket of water into the sump pit and watch the pump activate and drain. If it does not turn on, check the power supply and float switch. A failing pump should be repaired or replaced before heavy rain.

What should I do if water enters my basement?

Turn off power at the breaker if safe, and shut off the main water valve. Move valuables to higher ground. For deep water or if you are unsure, contact local water damage pros for extraction and drying.

Will my insurance cover flood damage?

Policies vary, and your insurer decides what is covered. Standard homeowners policies often exclude flooding from rising water, but some cover water from burst pipes. Review your policy and ask your agent about flood coverage before fall storms.
