Basement Remodel questions, answered by experts

When considering finishing your basement, take into account a few pros and cons:

Pros

  • Can increase the value of your home

  • Separate space from the rest of the house 

  • Customize and personalize the basement to suit your needs and style

  • Increase the amount of living space in your home

Cons

  • May not regain enough value to cover the cost of finishing

  • Lack of natural light if it’s below ground level

  • Moisture or flooding can cause costly damage

  • Installing plumbing and electrical can be messy and costly

Joists and beams 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.

Finishing a basement normally takes four to eight weeks, but the timeline depends on the size of your basement, your contractor's availability, and the extent of finishing work. Framing the basement will take three to five days, while adding electrical and rough-in plumbing can be another three to five days. Adding drywall can take five days, and floor installation can take two to three days. Final touches, like painting and adding trim, will take another week.

Key trends include home gyms, theatre rooms, additional rooms (bedroom/office), and more, with personalized styles reflecting individual preferences.

Assuming you are going for a full remodel for an average-sized basement with a reputable contractor, the process can take up to two weeks or more. Remember that basements have many stairs and often difficult access—it’s not like working in the entryway. The shuttling of materials, increased need for ventilation and safety precautions, and making sure everything can be removed through a doorway all increase time and cost.
