Since this basement is not entirely underground - it includes a walk-out entrance on one side -- new egress windows bring natural light into the basement. A simple Roman shade in fun fabric softens the space and brings all the colors of the room together. Egress windows provide an emergency exit; most building codes require one in every bedroom and in habitable basements. Adding one will likely increase the value of a home, as it provides safety, natural light, and increased airflow.
The cost of a small basement remodel—changing flooring and moving one wall—can cost a few thousand, whereas a major remodel of adding another bathroom and bedroom or an entire downstairs apartment can cost tens of thousands. You might have to move walls and plumbing, pull up flooring, tear down ceilings; and upgrade the sump pump, HVAC, and electrical amperage.
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.
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.
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.
"It's always easy to save money if you are willing to put in some sweat equity. Tackling the mold and termite damage was so disheartening and disgusting, but we survived, and the room is now safe, livable, and functional for our family. It's a great family recreation room. We keep our toys and games down here, and there is plenty of storage, so everything has a place. Despite not having a ton of natural light, this place still feels cozy and inviting to us."
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.
The average cost to install an HVAC system in the basement is $4,000 to $6,400 with new ductwork costing an additional $1,500 to $3,000. You might not have to install a separate HVAC system for the basement if the existing unit upstairs can handle the extra workload. If it can’t, then either upgrade your existing unit or install a second unit downstairs. You’ll have to install new ductwork and ventilation either way, unless you install a mini-split system.
Concrete will always crack eventually, and any existing foundation must be inspected before a basement finish to see if it’s in good condition. Minor foundation crack repairs cost $620 or more to fix, while major repairs that require hydraulic piers can cost $10,000 to $15,000. If your foundation is sinking, mudjacking costs $3 to $6 per square foot to raise the slab.
Basement waterproofing costs about $1,480 for simple crack filling with an average of $2,000 to $6,000 for drainage improvements. Costs range from a minimum of $250 up to $20,000. Most homeowners waterproof after they discover water in the basement from poor drainage around the foundation and walls. Waterproofing will be a lower cost if it's included in a larger basement finishing project.
For homeowners who are seeking fully remodel a basement, then they will be aiming to spend anywhere from $30,000 to $65,000. The varied range depends on the extent of the renovations that are made to the space. The addition of bedrooms, bathrooms, exterior insulation, electrical wiring, plumbing, flooring, furniture, light fixtures and the help of a contractor will all cause an increase in the price. Of course, the cost to remodel a basement will also depend on the square footage of the space.
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.
