Q: What are the disadvantages of a walkout basement?

• <div><p>Walkout basements cost more than other kinds of basements, and can also increase your risk of leaks as well as a loss of insulation, leading to higher heating and cooling costs. Improperly installed walkout basements may lead to structural issues with your foundation, so ensure you&rsquo;re working with a contractor who has extensive experience with this kind of basement. </p></div>

Q: How do I plan for a basement remodel?

• <div><p>Create a checklist, reimagine the space use, set a realistic budget, choose materials and aesthetic details, and get professional support for guidelines and troubleshooting.</p></div>

Q: Does a finished basement need ventilation?

• <div><p>Although it&rsquo;s not required, air ventilation in a finished basement can help improve the air quality, prevent moisture and mold issues, keep musty odors away, and also maintain the air quality throughout the rest of your home. Proper ventilation will help maintain the value of your investment in finishing your basement. Try <a href="https://www.angi.com/articles/how-improve-ventilation-basement-remodeling-project.htm">basement ventilation methods</a> like installing vents or a dehumidifier for best results.</p></div>

Q: Is finishing a basement worth it, and how much value does it add?

• <div><p>Yes, in most cases, finishing a basement is worth the cost. The project adds valuable, usable square footage to your home and typically provides a return on investment (ROI) of 70% to 75%. For example, an average basement refinishing project costing $32,000 could add between $22,400 and $24,000 to your property's value. The final value added depends on factors like your location, the quality of materials and workmanship, and the features you include, such as a living space, bedroom, or bathroom. To be officially counted in your home's total square footage, the finished space must comply with all local building codes, including requirements for points of egress. However, in areas prone to flooding, a finished basement might be seen as a liability by potential buyers and could potentially decrease your home's value.</p></div>

"Amanda was really very good! At first I was very skeptical, thinking why did I pay money to just speak with someone on the phone about my kitchen remodel project... but after just a few minutes of her addressing some of the issues/questions I emailed to her earlier, I knew it was worth it. It was very clear that she knew her business and she gave me several ideas that I had not even thought about. I told her that I would definitely recommend her to friends and I will very likely use her again myself for my next home project!
