Basements are common, often finished, and older brick bungalows and Denver Squares have original plumbing. Newer neighborhoods like Central Park (formerly Stapleton) are mostly modern construction with finished basements and sump pumps. Denver's older homes often have unfinished basements with original drain lines, and some have converted basement apartments.
Licensing in Colorado: Colorado doesn't license general contractors statewide. Cities and counties, including Denver, license contractors locally, while plumbers and electricians are licensed by the state.

Sewage & Biohazard Cleanup questions
Does homeowners insurance cover hail damage in Denver?
Generally yes, though many Colorado policies have separate wind and hail deductibles.
Do Denver contractors need a license?
Yes. Denver licenses contractors locally through Community Planning and Development.
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.
