Q: Can I remodel a basement myself?

• <div><p>Unless you have extensive experience in construction work, remodeling a basement is best left to a professional. There are several tasks associated with this project that require exact precision, including:</p><ul><li><p>Replacing insulation </p></li><li><p>Replacing carpet or other flooring </p></li><li><p>Adding heating and cooling</p></li><li><p>Adjusting or adding walls and doors</p></li><li><p>Altering or adding plumbing elements</p></li></ul><p>If any of these elements is done incorrectly, it could severely impact the quality of your basement remodel and be dangerous. Changing a basement often comes with <a href="https://www.angi.com/articles/finished-basement-code-requirements.htm">code safety requirements</a>, like egress windows and proper ventilation. Therefore, leaving it up to a professional is often the best decision.</p></div>

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: How much basement wall bowing is acceptable?

• <div><p>Any bowing in a basement wall indicates a problem that needs to be addressed by a professional. If your basement wall bows more than 1 inch, it's time for an inspection. Generally, a wall can bow up to 30% of its thickness (around 2.5 inches for an 8-inch-thick wall) before it becomes an urgent situation. Bowing of 2 to 4 inches is more straightforward to fix than bowing of more than 4 inches, which will require significant repairs. If the bowing is more than 6 inches, the wall will likely need to be replaced. The sooner you address the problem, the easier and less expensive the repair will be.</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: Would the newly raised basement ceiling need to be finished?

• <div><p>You can <a href="https://www.angi.com/articles/how-paint-walls-ceiling-and-trim.htm">paint your ceiling</a> or install a drywall ceiling if the ceiling is unfinished, as they take up less headroom than drop ceilings. </p><p>If there are pipes in the way of ceiling installation, you can do one of two things: reroute the pipes or adjust the installation to fit, which will cost extra.</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!

Basement Remodel questions, answered by experts

Unless you have extensive experience in construction work, remodeling a basement is best left to a professional. There are several tasks associated with this project that require exact precision, including:

Replacing insulation
Replacing carpet or other flooring
Adding heating and cooling
Adjusting or adding walls and doors
Altering or adding plumbing elements

If any of these elements is done incorrectly, it could severely impact the quality of your basement remodel and be dangerous. Changing a basement often comes with code safety requirements, like egress windows and proper ventilation. Therefore, leaving it up to a professional is often the best decision.
