Basement Finishing Costs

How much does it cost to finish a basement? Use this guide to find out, then decide which route is best for your home and budget.

By: Caroline Shannon-Karasik

There are some options when it comes to finishing a basement, and they all come with a cost.

If you choose a basic do-it-yourself makeover, including adding moisture control, framing in walls and adding decor and furnishings, your cost will run between $10,000 and $27,000. Waterproofing sealants and additional insulation are just a few of the considerations that will be factored into the final finished basement cost. The price will, of course, also be affected by how much renovating is being done.

If your renovation is extensive, requiring plumbing or electrical work (such as building a bathroom or installing HVAC), we recommend hiring a contractor. Expect this type of basement to cost more at least $65,000.

A basement finishing system is another option, running $45,000 to $55,000. These out-of-the-box systems include everything from moisture-proof, insulated wall panels to ceilings to lighting. You'll need to hire a professional to install them, but you can have a finished basement in as little as two weeks.
