Heavy rain floods basements through foundation walls and window wells. Cloudbursts overwhelm storm sewers and back water into basement drains. Sligo Creek and Rock Creek rise quickly in heavy rain. Remnants of hurricanes bring heavy rain that floods basements and creeks across Montgomery County.
Woodside and Four Corners have 1920s–1950s homes with basements and aging plumbing. Wheaton and Aspen Hill have mostly 1950s–1970s ranch and split-level homes with finished basements. Many 1950s homes in Wheaton and Four Corners have finished basements with carpet and drywall over old block foundations. When a sump pump fails or a sewer backs up, water spreads across the whole lower level quickly, and fast extraction makes the difference between drying and replacing materials.

Sewage & Biohazard Cleanup questions
Do I need a permit for repairs in Silver Spring?
Cleanup and drying don't. Structural, plumbing and electrical repairs need permits from Montgomery County Department of Permitting Services.
Does insurance cover a flooded basement in Silver Spring?
It depends on the source. Burst pipes are often covered, sewer backup needs an endorsement, and groundwater flooding needs flood insurance.
Can I clean up a small sewage backup myself?
A small backup on a hard, non-porous floor sometimes can be with gloves, boots and disinfectant. Anything that reached carpet, drywall or other porous materials needs professional cleanup.
Does homeowners insurance cover sewage backups?
Usually only with a sewer or drain backup endorsement. Flooding from outside needs a flood policy.
