Insulation will help to control the temperature and moisture, and it can act as an additional soundproofing agent. Spray-applied closed-cell foam insulation prices range from $700 to $4,000 or $32 – $80.50 per cubic square foot, per 1” of thickness sprayed. Foam is recommended for basement insulation because it is not air permeable—it won’t cause condensation to build up between the insulation and concrete walls.
Increasing numbers of homeowners decide to enhance the existing concrete in their basement instead of covering it up. Stained and painted concrete floors offer many benefits, including their suitability for people with allergies. Skilled contractors can reproduce the look of slate, tile and marble, or they can apply dyes, paints and stencils in a variety of designs.

When it comes to basement remodels, the most costly way is to start with bare bones. If all you have is concrete walls and floors, you need to add framing, electrical, plumbing, flooring and trim. Basement finishing in a newer home that already has plumbing and electrical roughed in, a watertight foundation and some insulation installed—but no final finishes (like drywall or paint or carpet)—usually costs less than remodeling an already finished basement. This is because when you already have a finished basement, the pros will need to do demolition at the beginning of the project, which can add $500–$1,500 to overall costs.
According to real estate agents and appraisers, a bedroom must have a door, window and closet. Adding a closet to your basement bedroom is crucial to adding value to your basement addition. There are a few components that will affect the cost, the size of the closet being the biggest. The average cost to install a closet is $1,779, with most homeowners spending between $1,272 and $1,917. More than likely, your closet cost will be lower seeing that the size of the closet won’t be nearly as large as your master bedroom or other main bedrooms.
Because basements are usually below ground level, water seepage and moisture issues have to be resolved before construction can start. Prior to creating a project bid, most contractors will inspect the area to check the interior floor and walls for dampness and make sure the exterior of the foundation is in good shape. Depending on how watertight the basement and foundation are, it may be necessary to protect the basement from future water damage after it’s finished, often through the installation of sump pumps. This work can cost anywhere from $700-$3,000, depending on what needs to be done. Learn more about basement waterproofing. To help prevent moisture problems, homeowners can clear downspouts and gutters of debris to ensure that they help keep moisture away from the foundation.
You can fit a full bathroom with tub/shower combination in a room that measures 40-square feet. However, on average, a smaller bath (with just a stand-up shower) or a half-bath usually needs to be about 30-square feet for comfort and functionality. Depending on the basement space and layout, you may be able to go with a larger 60-square feet or more bathroom space. Creating bathroom with a separate water closet may require 100-square feet or more.
Basement remodeling adds value to your home, increases your useable living space, can protect your foundation from moisture damage, and looks great. Many people remodel a basement to create space for an aging parent or to make room for more children. Another reason for basement remodeling is to create a rentable space that is separate from the rest of your home for a long-term renter or for short-term renting.
Basements can be daunting spaces for remodeling. Cluttered, dark, and chilly, basements often convince homeowners to turn their attention to other projects in the home. But basements don't have to stay that way. They can be remodeled and finished so that they not only integrate with the rest of the home, but become a beautiful and valuable asset to the property.
