Estimate the overall cost to install drywall in the basement at approximately $1.50 per square foot. The basic drywall panel measures 8-feet tall and 4-feet wide and is available in thicknesses that range from 1/4" to 5/8". This standard panel usually costs between $10 and $20. Price will vary depending on the brand, panel's thickness, and if it has any special features like mold resistance which may be beneficial for a basement space. Other material costs when adding drywall include the hardware to secure it to the framing, joint tape, and drywall mud.
Assumptions: The flooring in this calculator is carpet. For hardbood flooring or tile your cost will be higher. The costs estimated here are from finishing your basement using typical materials. If you want high end bathroom fixtures, flooring, etc add another 20% to the bottom line. This estimate includes adding one new full bathroom with rough-in plumbing in place.
Bedrooms – A common strategy is to set up a couple of extra bedrooms in the basement for guests. This is especially beneficial for families that love to entertain on a regular basis. You can easily have guests stay over without disrupting the family space above. Basement bedrooms can also come in handy if you have older kids that cannot share bedrooms any more. Plus, you could also add a small kitchenette and bathroom for convenience.
With a level, smooth surface you also have tons of other flooring options, based on your decorative scheme and your budget. A relatively inexpensive and easy option is carpet, with a carpet pad beneath it for added comfort and to keep your feet warmer in winter. Peel and stick vinyl tiles are another option, and they come in various styles, colors, and price ranges for any budget.
But if the moisture is due to a lack of ventilation and inadequate drying on the inside of your basement, that should be an issue that you can address as a DIY project. A dehumidifier can remove lots of water from the atmosphere of your basement to dry it out, and running a dehumidifier in your basement is probably a good investment. You can buy a heavy-duty one for around $200-$250 that can literally remove 3-4 gallons of moisture from the air each day, if necessary.
"I have found many of my ideas reading your magazine. I cut out pages and put them in a folder. When I first moved in, I didn't even have a TV, so I would just sit, read, and picture the house and basement finished. It now looks just as I pictured it. I saved by using recycled material: The rusty tin was from an old building that was being demolished; barn boards were from an old barn near my parents' farm. The barn door came off another old barn of a friend who said it was from an old boxcar they cut up in the 1940s. My grandfather built the house in 1927 and hand-dug the basement with my grandmother. Now my kids will have great memories of the house—and my grandparents, I know, would be happy."
Determine your budget and costs to finish a basement will help get bids before you make a final decision. For example, you may find a cheaper drywaller than you expected, and can use that extra money to add a bedroom. Or you may find that carpet was more expensive than planned, and you will have to make a dry bar with no sink instead of a wet bar. The budget is a guideline for what goes into your basement, and is really the major factor in determining what your space will be. The costs of labor and material will begin to shape your basement within your budget. One final note on your budget. Unless you plan to spend a long time in the home, you will want your budget to be lower than the value it will add to your home. You can determine the general value added by talking to realtors or appraisers and using comparable sales in your area. This is very important because you don't want to spend $25,000 on your basement and only add $15,000 to the value of your home.
In addition to floors and walls, upgrading your basement ceiling is another option to consider. Finishing your basement creates a new room in your home and a part of any room is the ceiling. While it’s cheaper to leave the ceiling the way it is, many basements have exposed wiring and duct work that service the home above. In certain cases, leaving all this exposed may be the better option, but for others, upgrading the ceiling could be the right choice. Understand that any addition to the room will up the overall price, so be sure to make the right choice for the space and your wallet.
How fast the job needs to be completed has a significant impact on the final price. A professional team can take a basement from framing to complete in about 45 days. A DIYer typically needs more time. If things need to be inspected, inspectors work on their own schedule, and if concrete needs to be poured, time must be allotted for it to properly set.
