Daylight Basements on Hillside Lots
Why the lower level of a hillside house takes the water.
AUBURN NEIGHBORHOOD · WEST HILL
Water coming in along the uphill wall, or a lower-level room with wet carpet? Wet ceiling, wet floor, wet crawlspace: one number.
West Hill homes sit on a slope, and water on a slope moves downhill through the soil. After a long rain, that water reaches the uphill side of a house first. On a home with a daylight basement or a lower floor dug into the hill, it presses on the wall and finds the joint at the floor. Lots here range from older one-story homes on larger parcels to newer builds near Peasley Canyon Road, and the lower level is where water tends to show up. On the downhill side, a slider or a window well at grade can let surface water straight in during a heavy storm.

Tell the company whether the water came in at the floor along a wall, through a window well or door, or from a fixture. Each points to a different source.
Calls from here usually involve ceiling water damage, wet drywall and floors, basement and crawlspace water, water removal, flood cleanup or the whole restoration and mitigation job. One number covers all of it.
Gutters that overflow onto a hillside lot send water straight to the lower level; clear them before the rainy season.
