What is the hardest part of finishing a basement?

• <div><p>The most challenging part of finishing a basement is addressing moisture control. Basement waterproofing is an essential task that requires a professional’s skills and knowledge. If you don’t properly waterproof your finished basement, it’ll be vulnerable to dampness, water damage, and mold growth. Ensuring proper insulation and ventilation to combat these issues while meeting building codes adds complexity to your remodeling project.</p></div>

Q: What are the most expensive parts of finishing a basement?

• <div><p>Anything having to do with the structure of your home, such as raising the ceiling, is usually the most expensive part of finishing a basement. Another project component that could be a surprisingly high expense is adding an exterior entrance. </p><p>The <a href="https://www.angi.com/articles/what-average-cost-add-exitwalk-out-my-finished-basement.htm">cost of a walkout basement</a> can be anywhere from $5,000 to $35,000.</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: What adds the most value to a basement?

• <div><p><a href="https://www.angi.com/articles/finished-vs-unfinished-basement.htm">Finishing an unfinished basement</a> adds the most value, with an average return of 70% or $22,400. A bathroom addition in the basement will provide an ROI of 75%, but the higher cost will leave you with a lower actual return of $9,000, on average. Finishing a basement and adding a kitchen, bathroom, and bedroom to rent the space will leave you with the highest possible ROI, as you could see well over 100% if you rent the space out long-term.</p></div>

Q: Do I need permits for flooded basement cleanup or repairs?

• <div><p>Permits may be required for major repairs, structural work, or electrical and plumbing restoration after a flood. Check with your local building department to determine permit requirements and associated fees for your flooded basement cleanup project. Obtaining the correct permits helps ensure work is done safely and up to code.</p></div>
