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.

The time it takes to finish or remodel a basement can vary significantly, ranging from a few weeks to several months or even up to a year. On average, the construction phase can take four to eight weeks, but the total project time can extend to three or four months when including planning and permits. The timeline depends on several factors, including the basement's size, design complexity, the scope of the work, and your contractor's availability. A more detailed breakdown for an average-sized basement might include: framing (3-5 days), electrical and rough-in plumbing (3-5 days), drywall installation (5 days), flooring (2-3 days), and final touches like painting and trim (about a week). If preliminary work like installing a waterproofing system or addressing structural issues is needed, the timeline could extend to six to twelve months. Factors like difficult access, material transport, and ventilation needs can also add to the project's duration.

Yes, you can add a bathroom to an unfinished basement, but you’ll want to take proper precautions if doing so. As with any bathroom addition, you’ll need to make sure that it’s approved by local building authorities first. With unfinished basements, you especially need to keep an eye on proper ventilation practices.

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. 

The cost of a walkout basement can be anywhere from $5,000 to $35,000.

For most basement remodels, you’ll want to hire a general contractor. This is for a number of reasons, but the main two are that general contractors have dedicated teams they are comfortable with, and hiring one means you only have to deal with one pro. You may also get a better project quote since they can lump all their work and subcontracting into a single quote.
