Sewage & Biohazard Cleanup questions
What should I do if pipes freeze in my New Hampshire home?
Shut off the main water, open faucets, and warm the area gradually with a space heater or hair dryer, never an open flame. If a pipe has split, call for extraction before thawing finishes.
Do New Hampshire restoration contractors need a license?
There's no statewide general contractor license, so check insurance, references and reviews, and get a written scope and contract.
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.
