Hi folks. We've got an unfinished basement in Des Plaines, about 800 square feet, just concrete floor and exposed joists. With a second kid on the way, we really need the space: a playroom, maybe a small home office for me, and eventually a guest room. The basement stays dry as far as I can tell, though it gets cold down there in winter. I have no idea where to start or what something like this usually costs. We'd also like to avoid a project that drags on for months with a newborn in the house. Has anyone finished a basement recently, and who did you use?
