Compare financing options for renovating a basement

You have a variety of financing options to finish your basement, including credit cards, personal loans and HELOCs.

Small renovations: Consider a credit card

While you won’t want to use a credit card to finance your entire basement renovation, it can help pay for furniture and other small projects. And if you invest in a credit card with a high cash back percentage, you can recoup some of the money you spend.

What factors do I need to consider when renovating my basement?

Less expensive materials and doing it yourself will reduce the total cost of your basement renovation. Just keep in mind that certain projects — like working with plumbing or electricity — will likely require a professional.


By framing your basement, you’ll be able to shape your space into rooms — or at least have one large, open area that protects against the elements. But keep in mind that framing estimates typically only include the materials needed. Labor and insulation will increase the price you pay.


Drywalling is the next step when finishing your basement. The more walls you need to put up, the more you’ll pay. Although it may seem simple, precise holes need to be cut for egress windows, doors and electric outlets — as well as any plumbing or ventilation systems that need an outlet. While material costs may be relatively low, be prepared for higher labor costs if you have an extensive basement with multiple rooms.


If you’re starting from a blank concrete canvas, the flooring you want in your basement is up to you. Prices can vary greatly depending on the material you choose:

Flooring typeAverage cost per square foot
Laminate$1 to $6
Carpet$1 to $7
Linoleum$2 to $3
Ceramic tile$5 to $15
Hardwood$5 to $15

Labor costs will also vary. Some floors can be installed yourself. Others require precise work that can only a professional can do. As with all things home improvement, be sure to get a few estimates from different contractors before you settle on a price.


If your basement is old and only has a small breaker box, new wiring may be necessary to bring it into the 21st century. Materials could cost you anywhere from $6 to $10 a square foot, and labor can actually be cheaper if everything is already exposed. However, adding in a new breaker can increase the price of the job.


If you want to look up without seeing exposed pipes and ductwork, you’ll have to add in a ceiling. The cost of this step will depend on how low those pipes and ductwork hang. In general, you have three options:

  • Install a drop ceiling
  • Hang drywall paneling
  • Install tongue-and-groove wood

The amount you pay will depend on which material you choose and the cost of labor in your area.

Other materials and projects

Finally, there are smaller updates that can make a big difference in the comfort of your basement:

  • Paint
  • Furniture
  • Fixtures
  • Waterproofing
  • Ventilation
  • Plumbing

For waterproofing, ventilation and plumbing, check with your contractor to get an idea of how much these might cost for your space. Fixtures, furniture and paint are all up to you. If you want to save money, you can make these updates a little at a time once the major work is done.

What other costs should I consider?

Beyond the material costs for your basement, there are three other areas that will eat up your budget:

  • Contractor and subcontractors. Finishing a basement is a time-intensive task that requires the work of multiple professionals, including electricians and plumbers. While you can DIY some of the more basic projects, fully finishing your basement will require you to hire outside help — at an additional cost.
  • Permits. Any changes to the foundation or structure of your home will need to be approved by your local municipality. Permits and an inspector are necessary costs to make sure everything is up to code. If not, you may have to demo your space and start again.
  • Adding other rooms. If you want to add a bathroom, kitchenette or laundry room to your basement, expect your costs to rise significantly. These are expensive renovations on their own, and adding them to your basement can get more complicated when it comes to installing the equipment you’ll need to make things functional.

Bottom line

The cost of finishing your basement will depend on its current condition and the updates you’d like to make. The less finished the space, the more it will cost to turn it into a cozy hideaway.

We’ve compiled a complete list of home renovation costs to help you find tips on sticking to a budget, choosing what parts to DIY and more.
