Sewage & Biohazard Cleanup in Maine
Sewage backups, contaminated floodwater and other biohazards are Category 3 losses. They need protective equipment, removal of porous materials that were touched, cleaning and disinfection of everything else, and careful drying.

In Portland: Strong nor'easters push storm surge onto the waterfront and Commercial Street, and the January 2024 storms brought record tides to Portland. In Augusta: The river floods downtown, as in 1987 and 2023.
Older Maine homes often have limited insulation, oil-fired boilers that can puff back soot, and private wells and septic systems. All of these affect water, smoke and sewage cleanup.

Other risks in Maine
Frozen and burst pipes
Extended sub-zero spells freeze pipes in exterior walls, crawlspaces and unheated additions. Seasonal camps and second homes are especially at risk if the heat fails while nobody is there.
Ice dams
Heavy snow loads and heat loss through older roofs create ice dams that force meltwater under shingles and into walls and ceilings.
Basement moisture
Fieldstone and older poured foundations let groundwater in during spring melt, and damp basements grow 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 protect a Maine camp or second home from frozen pipes?
Winterize it: drain the lines, shut off the water, and add plumbing antifreeze to traps. If you keep the heat on, install a low-temperature alarm or a remote sensor and have someone check after storms.
What is an oil burner puffback?
A malfunctioning oil burner can release a burst of soot through the house. The soot is oily and smears, so professional soot cleanup is usually needed.
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.
