"Lilco was a great company to work with! They are easy to communicate with and answered all of my questions and concerns. They are reliable and trustworthy. My kitchen and bathroom came out better than I could have imagined. I couldn’t be happier and hope to be able to remodel my other bathroom in the near future."

"Sam the Man did several remodels in my home. I had 2 bathrooms, a full kitchen ( with a wall that was removed) and the basement. Every room was brought down to the studs. Sam is very neat, clean and knew exactly what look I was trying to achieve. He even helped me pick out the kitchen cabinets. Sam goes above and beyond my expectations. 5 stars is just not enough."

Basement Remodel FAQs, answered by experts

You should always use high-quality lumber for your framing in order to ensure it will last the test of time and resist moisture. Use 2-foot by 4-foot lumber that is pressure-treated for your framing.

The cost of finishing a basement is about $18,400 on average. As you can see, the framing portion of this project costs less, because you’re essentially just dealing with laying the foundation for a finished basement. The finishing portion of the project involves a lot more intricate work and design, as well as high-end materials.

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.

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.

If you don’t have a crawl space but have a partial basement you want to make deeper, you can expect to spend a little less—between $40,000 and $90,000 on average. However, if you’re not adding new finished square footage, you won’t see much in the way of ROI.
