"When Ballard came out to give an estimate, he was very nice and knew his business. We noticed he did not take notes and said we would get the estimate in a week. After 2 weeks I emailed to ask for the estimate, and was told it would come that weekend. Another 2 weeks went by and I finally got it after yet another email. The estimate was missing some items. After all this we felt we were not valued customers and went with another company."

Basement Remodel questions, answered by experts

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.

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.

Yes, most general contractors require a down payment for project completion. A reasonable down payment for a contractor is 10% to 25% of the total project cost, though that will vary based on project size and location. The down payment helps cover the upfront costs of materials and permits and helps ensure payment for the project at hand. 

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.

Some older homes have toilets in the basement to combat sewage backups. This type of toilet, also known as a Pittsburgh potty, acted as a safety valve over the incoming sewer line. If a line backed up, it would back up into the toilet because it was the lowest fixture in the home, keeping it out of sight and away from the finished areas of the house.

Basement toilets were also used by workers with messy jobs, like those who worked in coal mines or steel mills. This way, they could clean up and avoid tracking dirt through their home.
