"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.

The difficulty of adding a basement to an existing house can vary depending on the house’s location, the size of the basement, and the type and condition of the existing foundation. Adding a basement is a job best handled by the pros, so you’ll need to enlist professional help for this project.

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.

Professional remodelers streamline the process, manage permits, and handle renovations efficiently—significantly mitigating risk while maintaining standards.

The average cost of remodeling a basement is $30 to $75 per square foot. If your space is unfinished and looks like it may need more help, use the higher number when calculating your estimated basement remodeling costs. A good rule of thumb is to add an additional 20% to the top of your estimate to cover any “what if” situations.
