Sewage & Biohazard Cleanup in Colorado
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.

Partner coverage for sewage and biohazard cleanup in Colorado includes 283 ZIP codes, with local pages for Denver, Aurora, Boulder, Littleton, Fort Collins, Arvada, Greeley. Call with your ZIP to confirm a company serves your address.
In Colorado Springs: Nearby wildfires bring smoke and ash, and burn scars increase flash flooding. In Aurora: Heavy rain overwhelms sump pumps and floods finished basements. In Pueblo: Summer storms flood arroyos and low streets. In Boulder: Boulder Creek and its tributaries flood quickly in heavy rain, as in 2013.
Basements are common along the Front Range, and mountain homes and cabins face heavy snow loads and freeze risk.

Sewage & Biohazard Cleanup questions
Does homeowners insurance cover hail damage in Colorado?
Generally yes, though many Colorado policies have separate wind and hail deductibles, often a percentage of the home's insured value.
Do Colorado contractors need a license?
Licensing is local. Check with your city or county, such as Denver's contractor licensing, and ask for 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.
