Strong nor'easters push storm surge onto the waterfront and Commercial Street, and the January 2024 storms brought record tides to Portland.
Older homes often have fieldstone or brick foundations, limited insulation and oil-fired heat. Wood-frame multi-families stack plumbing, so leaks spread down through units.
Licensing in Maine: Maine doesn't license general contractors statewide, though electricians and plumbers are licensed. Ask for insurance, references and a written contract. Maine law requires written contracts for home construction jobs over $3,000.

Other risks in Portland
Frozen pipes and ice dams
Sub-zero cold freezes pipes in exterior walls, and heavy snow creates ice dams on older roofs.
Oil burner puffbacks
Malfunctioning oil burners can coat a house in soot, which needs professional cleaning.
Wood-frame multi-families
Portland's three-story wood-frame apartment houses on Munjoy Hill and in the West End stack bathrooms and kitchens. A frozen or burst pipe on the top floor can travel through every unit below before anyone shuts off the water.
Seasonal rentals
Short-term rentals and second homes around the peninsula can sit empty through cold snaps, so a failed furnace or burst line may run for days before it's found.
Signs you need sewage & biohazard cleanup
- Water or waste coming up through floor drains, toilets or tubs

Sewage & Biohazard Cleanup questions
Do I need a permit for water damage repairs in Portland, Maine?
Cleanup doesn't. Structural, plumbing and electrical repairs need permits from the City of Portland's Permitting and Inspections Department.
How do I prevent ice dams in a Portland home?
Air-seal and insulate the attic, keep gutters clear, and rake snow off the lower roof edge after storms.
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.
