Q: What is the difference between a joist and a beam in a basement?

• <div><p><a href="https://www.angi.com/articles/joist-vs-beam.htm">Joists and beams</a> are both part of the flooring system above your basement, with the beams spanning the length of your home and getting support from vertical posts underneath, and joists usually spanning half the width of your home with no support posts underneath. The floor joists provide even support to the subflooring and flooring above, and they distribute that load to the beams. The beams then distribute that load down through the support posts to the foundation.</p></div>

Q: Are walkout basements included in square footage?

• <div><p>Walkout basements are not generally included in a home&rsquo;s square footage, although they may be if they meet certain conditions that depend on local regulations. A finished walkout basement used as a living space may be counted toward square footage in some locations as long as all codes for livable space are met.</p></div>

Q: What costs are associated with basement remodeling?

• <div><p>Costs are guided by renovation scope, materials chosen, project duration, structural needs, and labor. Prioritizing tasks prevents unforeseen expenses.</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: 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>

"We found Bielefeld Construction on Home Advisor and was surprised when Ray responded because we hadnâ t previously had a lot of luck on Home Advisor. We hired them for a master bedroom remodel and are very happy with the final outcome. We made a few changes here and there and Ray was very accommodating. All employees and subcontractors were pleasant, considerate and meticulous in what they brought to the project. We would definitely recommend Bielefeld Construction and use them again if the need arises. 5 star organization!"

"Ovation did a great job installing a new tiled shower in our basement bathroom. They were easy to work with on design and executed exactly what I wanted for a competitive price. However, the project took 2x the estimated time they rarely proactively communicated about timelines or who would be on the job site doing what when."
