Basement Remodel questions, answered by experts

There are several small, inexpensive upgrades you can make to upgrade your basement. Although you still need to adhere to building codes and obtain permits when necessary, you can complete small but mighty tasks like painting the masonry walls and installing entertainment devices to make the space more usable. 

In most cases, a contractor will ask you for a deposit that is a percentage of the total cost of your job, but you should never pay in full before work has begun. The up-front cost could be as much as 50%, or you might give a contractor as little as 10% up front. Discuss payment terms with your contractor before they begin the job to avoid surprises.

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. 

Common mistakes when finishing basement walls include neglecting proper insulation, insufficient moisture management, and poor ventilation. Not addressing these issues can lead to mold growth, water damage, and discomfort. Additionally, inadequate planning, improper framing, and rushing the project can result in subpar outcomes. 

It's essential to follow best practices, seek professional guidance if needed, and prioritize thoroughness and attention to detail.

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.
