The number of exact materials and amount varies on how big your basement is and the design you wish to achieve. Before you begin, take exact measurements of your basement space, and account for the number of walls you wish to put up, so you can purchase the correct amount.

Factors to Include Into Your Planning (headroom, Waterproofing, Soundproofing, Insulation…)

How Much Headroom Space Is Needed?

The building code requires a basement to have a 7 to 7½ feet clearance. If your current basement does not have this height, one possible solution is that you could dig up the flooring and lower the floor itself. It is a complicated and expensive job and may require professional assistance from a contractor. Another solution is, if it is possible for the ducts and pipes in the ceiling could be moved, creates overhead space that would help you adhere to the building code.

Steps to Finish Your Basement

If the walls in your basement are solely made of concrete, it is best to start here as your first step to finishing your basement. Tending to the walls of the basement will help make the space more comfortable as well as inviting.

Step 1: The Insulation Process

Install polystyrene foam insulation onto your foundation walls to insulate the basement. This is an effective and simple way to insulate the exterior walls of your basement.

  • Cut the foam pieces according to your ceiling height and subtract ¼ inch as a buffer during insulation. During this process wear safety goggles and use a circular saw or utility knife
  • Check to see if you cut it to the right height by placing it against the wall

  • Remove the foam and apply adhesive on it as an “S” shape beneath where you will place the foam. Allow it to sit for 30 seconds
  • Now, place the foam onto the adhesive
  • Repeat this step for the rest of the walls
  • After installing the foam pieces, you should seal all the seams of the foam pieces together with duct tape
  • Lastly, if there are gaps between the ceiling, the foam, corner and floors- seal them too


Step 2: How To Frame Your Walls

Start by cutting your 2×4’s to the right length. In addition to the ¼ inch buffer, further, subtract the thickness of the top and bottom plates for the vertical joists.

  • Your walls that run corresponding to your floor joists have to be installed with blocking in between the wall and the overhead joists. This will be done by placing a fitted 2×4 and nailing it to the joists. These blocks will be utilized to attach the frames and need to be installed every 2 feet.
  • Mark an ‘X’ that is 4 inches from the wall. This will be where the outer edge of the frame will be aligned to.
  • Construct the wall with the bottom plate near the wall on the ground. Using a framing nailer, connect the wall joists every 16 inches to the top and bottom frames. Shift wall joists to allow room for doors and windows as needed.
  • Bring up the wall and connect the bottom plate to the floor. This part will require you to use masonry nails, a masonry drill and a hammer. It is a must to wear protective gear for your safety.
  • Using your framing nailer and a stepladder, connect the top point to the above joists or blocks. As you work your way across the wall, before nailing the plate to the above joists, keep a level vertically to each wall joist to ensure the wall is sitting flat. If the wall is not straight, place a shim in between the top plate at the ceiling joists and then use the framing nailer to connect it.

Step 3: Installing Drywall

You should start by hanging your drywall after assembling your walls.

Using a drywall knife, consider any outlets or valves by measuring their location and cutting entry holes into the drywall board.

  • For your windows, after you have nailed the sheet to the wall, calculate the measurements and cut the required form out of the drywall.
  • Hang your drywall horizontally which will require fewer seams to finish and will make your work a lot easier.
  • Measure to ensure that each piece of drywall ends up on a stud. Trim where appropriate, using your utility knife.
  • Use drywall screws and a drill to attach the drywall to each stud, working to ensure not to tear the surface of the drywall paper. You shouldn’t be able to see plaster over the head of a nail. Using calk to protect the joints and screw the heads. Lastly, seal the seams with drywall tape and then repeat the process of caulking.
