When snow becomes liquid, make sure it’s flowing away from your house, not into it.
A warming trend may be good for the psyche, but it might not be so great for your house.
Drainage issues, roof problems and maintenance oversights could result in leaks now that the heavy snow is melting.
You may not be able to solve the underlying problems until spring arrives, but you can take some stopgap measures now to prevent or minimize damage, experts say.
Here are their suggestions:
Clear the snow
Once the ground thaws, melting snow acts much like an extended rainfall, said Bruce A. Tschantz, who taught civil and environmental engineering at the University of Tennessee and is now a consultant on water issues. If the melted snow has nowhere to go, it can collect against your house and seep into your basement, he said.
You may be able to prevent a basement leak by shoveling deep snow away from the foundation wall on the uphill side of your house, he said. But don’t just leave the snow there in a pile. You need to remove it to a lower part of the yard, or else it will just melt and run back toward the house.
Check the drainage
Tschantz said it’s a good idea to make sure you have clear, uncrimped outlets for your roof’s downspouts and any foundation drain that runs underground around the perimeter of your house. Those systems usually drain to either the street or someplace on your property. Sometimes the downspouts empty into the foundation drain.
Check that the openings from the gutters to the downspouts are clear, too, he said.
Make sure water from your downspouts is directed well away from your house, Tschantz said. That may require adding a flexible downspout extension that’s long enough to carry the water to a lower part of the yard. Those extensions can be removed to mow the yard.
Check your sump pump
If water does get into your basement, a sump pump is designed to get it out. Now’s a good time to make sure that pump is working, said Mike Mackin, owner of Mackin & Sons Plumbing in Norton, Ohio.
The best approach is to fill the pit with water from a garden hose, perhaps attached to a water heater or laundry hookup. Make sure the pump comes on as the pit fills.
You can also pull up on the float to make sure the pump turns on, he said.
Safeguard your valuables
The contents of your basement are vulnerable during a flood. Take a few minutes to make sure anything valuable is stored in waterproof containers or lifted an inch or more off the floor — perhaps on shelves, pallets or other supports. Tschantz said he puts small blocks under the computer equipment in his basement, just in case.
