A typical basement remodel costs around $90 a square foot, assuming moderate decor and finishes.

Unfinished Basement vs. Remodel

An unfinished basement isn’t a very usable space. At most, homeowners with unfinished basements may use the area for storage. Unfortunately, unless steps have been taken to waterproof the area, even storage can sometimes fail as belongings absorb the humidity and moisture of the basement.

A remodeled basement gives you additional living space without changing the footprint 1 of your home. Basements can be remodeled to become in home theaters, children’s playrooms, entertainment areas, and family game rooms. Because the steps to finish the basement are similar for most of these purposes, you can gain a lot of additional space and use from your home simply by finishing this area.

Things to Bear in Mind

Before beginning on your basement remodel, you’ll need to keep several things in mind that will pertain to the space.

Future Use

Simply finishing the floors, walls, and ceilings of the basement can help increase the value of your home. But putting extra thought into what you want to use the space for now, will save you on fees later. For example, if you intend to use this as a children’s playroom, then building shelves into the walls, adding egress windows, and putting down carpeting can all be done at the time of the remodel, rather than added later.

Square Footage

The size of your basement may impact what you plan on doing there. Measure the usable space carefully to determine whether or not you have the room for what you would like to do there.

Water Issues

Basements are known for being damp. As part of the renovation, you will need to address this, either through sump pumps 2 ($550), French drains 3 ($1,000 - $1,500), vapor barriers 4 ($50), or other methods. Waterproofing your basement costs around $5,000 on average.


Your basement will only be as sound as your current foundation. A remodel is the best time to deal with issues such as cracks or settling, before more invasive work is undertaken. If necessary, foundation repair costs between $5,000 and $7,000.

Permits and Codes

Most cities and towns will require a permit for basement remodels. In addition, there are several codes that dictate what can be done in this area. For example, a basement must have a ceiling height of a minimum of 7-feet. If your basement has a ceiling height lower than this, it may not pass code if remodeled. In addition, plan the cost of the building permits, around $430 on average, into your budget.

Vapor Barrier

Simply putting up drywall 5 isn’t always an option in the basement, because of the moisture in the walls. Vapor barriers 4, or plastic sheeting that helps seal out moisture, are required behind any framing that you put into your basement to help protect the finished walls. Vapor barrier 4 costs around $50 a roll.


Framing will shrink the space of your finished basement room slightly, but about 4-6 inches on all sides. Plan this into your calculations for the space, particularly in small rooms. New framing typically costs around $5,300, while the drywall 5 will cost about $200 per room.


If you plan on using your basement during the winter months, you will need to invest in insulation as well. Insulating the walls of your basement will keep the rooms warmer, and your utility bills down. Insulating one room of your basement will cost around $1,200 to $1,800.


Most basements are poorly lit, having little natural sunlight making their way in. For this reason, you should expect to add recessed lighting 6 or another type of lighting to your basement remodel to evenly illuminate the rooms. New recessed lighting 6 runs around $780.


In most cases, your HVAC system should already extend to the basement. If not, however, plan on running additional ducts or vents to ensure the finished rooms are adequately heated. Running new ductwork through your basement will cost around $2,000. Radiant heat is another option for basements, as it can be controlled separately and used only when the basement is. Radiant heat costs around $6,000 - $14,000 depending on the method used.

Basements can be finished in nearly countless ways. The costs don’t vary too much from project to project, as the bulk of the costs are within the finishing materials and labor. However, there are some variations based on what you want to do with the space.

Wall Options

The two most common methods of finishing a basement wall is to frame and drywall 5, like any other room of your home, or to use a basement finishing system, which involves interlocking panels, which go directly over your existing walls.

The cost to frame and drywall 5 a basement is around $5,500, while most basement finishing systems have costs starting at $20,000. The benefit of a finishing system, however, is that it’s fast and provides you with easy, instant access to the walls behind the panels whenever needed without needing to cut into the drywall 5 or repair it later.

Ceiling Options

Finishing the ceiling of a basement can be a tricky proposition. In most basements, important pipes, wires, and ducts already crisscross this area, often lowering the total ceiling height. If you were to install a drywall 5 or standard ceiling, you would be encapsulating these items, making them difficult to find and access in the event of an issue. Therefore, most basement ceilings are finished with some type of drop or suspended ceiling, sometimes known as an acoustical ceiling 9 or a grid ceiling.

Some basement finishing systems will also install the same types of panels on the ceiling as they do on the walls, for a cost of $20,000 to $30,000. A paneled ceiling or suspended tile ceiling costs around $125-$350, and still gives you access to the pipes and wires above.

Keep in mind, that in order to cover your ceiling, you may need to lower its total height to below the lowest item in the basement, often ducts or beams. If this will drop your ceiling below 7-feet, you may want to consider simply painting the existing ductwork and ceiling and leaving it bare to pass code.


Labor is a big percentage of the costs in any basement remodel. Even the most basic basement finishing will likely include:

  • A plumber to install a drain or hook up a bathroom: $45-$65 per hour.
  • An electrician to install new lights or to run network cables: $65-$85 per hour.
  • A carpenter to frame the new walls: $70 per hour.
  • A flooring installer: $5-$10 per sq.ft.

Add to this any custom work that you may want to have done to turn the basement into the type of room you have in mind, and the labor could continue to mount. Most people also find that they need a painter ($20-$35 per hour), and in older homes, asbestos 10 testing and removal ($1,500) is also recommended before the work can begin. For these reasons, many homeowners often choose to use a basement finishing system, which often has one set price for materials and labor (around $50,000 per basement) and decorate later as they choose.

Enhancement and Improvement Costs

  • Most finished basements include the addition of a bathroom in their final costs. Bathroom additions typically cost around $125 a square foot.
  • If your basement is not already waterproof, you will want to have this addressed at a cost of around $5,000.
  • Egress windows should be added to any basement bedrooms, as well as family rooms and playrooms to ensure the safety of occupants. An egress window costs around $4,000.

Additional Considerations and Costs

  • Pay close attention to the size of the space, including ceiling height as you plan your remodel.
  • Set a budget early on; if your basement is too large to afford to remodel all at once consider remodeling part and leaving the rest for storage.
  • Basement finishing kits are available that can allow you to finish the basement DIY for around $20,000.
  • If you can, consider finishing the basement piecemeal; while it may take longer, it may help you keep costs down. A rush job may increase costs.
  • Most people will want to furnish their basement room. The cost of this will depend largely on the purpose you have set up for it. For example, a children’s playroom may require storage bins, while a family room may require new couches and chairs.
