Things You'll Need:
- 3-1/2 inch galvanized screws
- rubber washers
- J-Channel
- Wood stakes
- Pressure treated 2X4's
- Self tapping screws
- corner channel
- vents
- Drill
- Steel Ribbed Sheets
-
Step 1
Measure 4 inches above the bottom of the mobile home. Screw the J-channel along this straight line. You can use the bottom trim as your guide. Go all the way around your mobile home. This will be the top track of the skirting.
-
Step 2
Hang a plumb-bob from one of the corners of the mobile home. Pound a piece of rebar in the ground where the weight hangs. Repeat this step for each corner of the mobile home.
-
Step 3
Tie string around one of the pieces of rebar. Walk around the trailer, making sure the string goes around each piece of rebar at every corner. Pull the string tight. The string marks where the bottom track will lie.
-
Step 4
Lay your treated lumber all around the perimeter of the mobile home. Make sure the lumber sits on it's edge directly behind the string line. Every 5 feet, pound in wooden stakes behind the 2X4's.
-
Step 5
Lift the lumber with a partner about an inch off the ground. Secure the 2X4's to the stakes with the galvanized screws. Make sure not to screw too tightly.
-
Step 6
Measure the distance between the bottom of the 2X4 and the top track every 3 feet. Elevations can change quickly, so you will need to measure often. Cut the ribbed steel to fit these measurements and screw to the outside of the lumber. Also, make sure to add 1 self tapping screw to the middle of each seam. Once you get to a corner, add the corner channel for a more pleasing appearance.
-
Step 7
Decide how many air vents your skirting will need. For every 150 square feet of floor, you will need 1 square foot of air vent in the skirting. Once you have determined how much venting you need, cut your determined amount of 1 foot squares around the skirting. Screw your vents over the holes.
