Late-summer storms tracking up the coast bring heavy rain and wind. Shoreline towns can see surge, and inland river valleys can flood.
In Hartford: Hartford is protected by dikes along the Connecticut River, but spring melt and tropical storm rain still raise groundwater and can back water into low-lying basements. In New Haven: Low areas near the harbor and Long Wharf flood during storm surge and heavy rain. In Waterbury: The Naugatuck River and Mad River rise quickly in heavy rain, as in the 1955 flood. In Stamford: Sandy and Irene pushed water into low-lying neighborhoods along Long Island Sound.
Much of the state's housing predates modern insulation and plumbing codes. Galvanized supply lines, cast-iron drains and older oil-fired heating systems are still common, and each can fail in a way that leads to water or soot damage.
Connecticut requires home improvement contractors to register with the Department of Consumer Protection (DCP). Ask for the registration number before work starts.

Other risks in Connecticut
Ice dams and roof leaks
Heat escaping into poorly insulated attics melts roof snow, which refreezes at the eaves and backs water under shingles. The leak often shows up as stained ceilings along exterior walls after a thaw.
Basement water
Heavy rain and spring snowmelt raise groundwater, and older foundations without interior drains or sump pumps take on water. Damp basements are also the most common place for mold.
Signs you need sewage & biohazard cleanup
- Water or waste coming up through floor drains, toilets or tubs

Sewage & Biohazard Cleanup questions
How do I stop ice dams in Connecticut?
Air-seal and insulate the attic so heat doesn't reach the roof deck, keep gutters clear, and rake snow off the lower roof edge after big storms. Ice and water shield under shingles at the eaves limits leaks.
How do I check a restoration contractor in Connecticut?
Look up their home improvement contractor registration with the Connecticut Department of Consumer Protection, and ask for proof of insurance and IICRC certification.
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.
