Questions homeowners ask
How much does it cost to finish a basement of 2,000 square feet?
At mid-range finishes, roughly $72,000 to $108,000. Adding a full bathroom is about $14,000 more, and a bathroom below the sewer line needs an ejector pump.
What's the most expensive part of finishing a basement?
Framing and insulation, then drywall — together about 35% of the budget. But the costliest surprise is water: existing moisture has to be fixed before finishing, which adds around $9,000.
How much does it cost to finish a 12x12 room in a basement?
A 144 square foot room is below what most contractors will mobilise for on its own. Expect to pay close to the job minimum of around $12,000 rather than a per-square-foot rate.
How long does it take to finish a 1,000 sq ft basement?
Six to ten weeks for a standard finish once permits are issued. Adding a bathroom or an egress window extends it, since both require their own inspections.
