"The project was complicated because we found after demolishing the old bathroom that our plumbing and water heater needed to be replaced which increased scope and timeline. Future Vision was quick to help us problem solve and adjust the plan, and did high quality work so we are very happy with the results."

Basement Remodel questions, answered by experts

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.

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.

A finished basement must have a heat and electrical supply with an entrance that meets building code requirements, such as a stairwell to the home's main living space. It often must include finished walls, ceilings, and floors. If the finished basement includes a bedroom, it should have a heat source, an egress window, and a closet.

Remodeling, as opposed to finishing, means altering an already finished basement by adding a bathroom, bedroom, or living area.

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 most challenging part of finishing a basement is addressing moisture control. Basement waterproofing is an essential task that requires a professional’s skills and knowledge. If you don’t properly waterproof your finished basement, it’ll be vulnerable to dampness, water damage, and mold growth. Ensuring proper insulation and ventilation to combat these issues while meeting building codes adds complexity to your remodeling project.
