How much does it cost to finish a basement?

• <div><p>It costs an average of $32,000 to finish a basement, and most projects total between $15,000 and $75,000. If you just want to make the space look a bit nicer and don’t need to <a href="https://www.angi.com/articles/how-to-turn-basement-into-living-space.htm">convert the basement to legal living space</a>, you could spend as little as $3,000 to install drywall and flooring. On the other end of the spectrum, your costs could rise to $100,000 if you want to make structural changes to the space, repair existing structural damage, waterproof your basement, or install a kitchen and bathroom along with living space.</p></div>

Should you pay a contractor up front?

• <div><p>In most cases, a contractor will ask you for a deposit that is a percentage of the total cost of your job, but you should never pay in full before work has begun. The <a href="https://www.angi.com/articles/how-much-should-i-pay-general-contractor-prior-starting-job.htm">up-front cost</a> could be as much as 50%, or you might give a contractor as little as 10% up front. Discuss payment terms with your contractor before they begin the job to avoid surprises.</p></div>

Q: How much does it cost to make bigger windows in a basement?

• <div><p>Making a window in a basement larger costs an average of $4,200. You&rsquo;ll need to pay an average of $550 to have a structural engineer plan the project, $500 to $1,500 for the installation labor, and an average of $2,200 for the excavation and window well installation. The remainder will go toward pulling permits, installing trim, and repairing drywall on the interior.</p></div>

Q: Should you refinish your basement?

• <div><p>Finishing a basement can provide a great return on investment, by increasing the market price of your home when you want to sell. Beyond that, there are many reasons to finish your basement. Doing so expands the usable square footage of your home, so you can enjoy it more, even as your family grows. Renovating your basement costs less in terms of time, energy, and money than having to search for and buy a new home.</p></div>

Q: Is it cheaper to build up or add a basement?

• <div><p>Building up by adding square footage to the top of your home is often less expensive than adding a basement, but it depends on the specifics of your house, your property, and supply costs. Because building a basement requires excavation, it can be a more expensive option than building up.</p></div>
