Installing all of the necessary plumbing and electrical work while walls and floors are unfinished will result in savings.Starting from scratch doesn't require demolition, which can save you around $2,000. Framing may be necessary to define rooms and spaces. System upgrades usually call for minor expansions to the HVAC and electrical systems, but not adding plumbing. The bulk of the cost, however, is in flooring and finishing. After wrapping things up with carpeting, drywall, and ceiling material, you can expect to pay anywhere from $6,500 to $15,500.
This before and after photoset is of a raised ranch basement. In the before picture you can see the outdated and unappealing wood paneling on the walls. The room also looks dark because the window is not allowing natural light to flow in. In the after picture you’ll see that our crew turned this dark and outdated basement into a bright, naturally-lit functional space.
Finishing the ceiling of a basement can be a tricky proposition. In most basements, important pipes, wires, and ducts already crisscross this area, often lowering the total ceiling height. If you were to install a drywall 5 or standard ceiling, you would be encapsulating these items, making them difficult to find and access in the event of an issue. Therefore, most basement ceilings are finished with some type of drop or suspended ceiling, sometimes known as an acoustical ceiling 9 or a grid ceiling.
Plumbing - Check locally for required permits and any zoning law regulations about adding in plumbing, or whenever working with septic and sewer lines. Planning your basement bathroom directly below or close to the pipes of an existing bathroom may help reduce the overall labor and costs. Remember that all drainage lines require a downhill slope to sluice away waste water. If this isn't possible, a sewage injection pump must be installed. An approximate cost of these pumps ranges from $150-$3,000.
But beforehand you’ll want to prep the brick or masonry walls by building a simple wooden framework against them that you will use to attach the paneling or gypsum board (another name for sheetrock).Do that by attaching 2-inch by 2-inch furring strips to the walls. These are inexpensive and lightweight lengths of wood that look kind of like skinny versions of traditional two-by-fours.

Of that amount, $15,000 on the labor cost and the rest on material. all walls demolished, cracks in the wall fixed, then insulated and rebuilt, new windows, new electricity wiring, new floor tiling, new web bar, new stairs build from scratch replacing the old. Also, built two closets, one with shelves and the other for clothe-hanging, two utility rooms, one of them where the burner is fire proofed, all walls plastered and painted, wood stained etc. The contractor worked 10 hours a day and finished the entire project in five weeks! (I cooked lunch and provided cold drinks.) could have build a bathroom for $3000, but I decided to do that another time.
