How to Fix a Mobile Home Floor

Replacing a bad floor in a mobile home is actually a very quick and simple task. The flooring of a mobile home is ran from floor joists. The joists are the supports that run through the floor and provide the builder with something stable to nail the subfloor to.The bad thing about these floors is the material is not as durable as materials built in a regular stick frame home. You will need to replace rotted pieces of plywood as quick as possible to prevent safety hazards in your home.

Things You'll Need

  • Measuring tape
  • Skill saw
  • Hammer
  • Nails
  • Plywood (1 sheet)
  • Matching flooring

Inspect the bad place in the flooring. You will want to assess the size of the problem area so you will know how much flooring you're going to have to rip up. If you cannot match up the flooring that is already down, you should go ahead and tear the old flooring up entirely and recover the floor.

Remove the flooring around the bad area. You will want to tear enough out to determine how much plywood you're going to cut.

Cut the bad wood out with a skill saw and cut it out to the floor joist. You will want to cover that bad area with a new piece of plywood. The plywood will need to be measured and cut to fit precisely on both floor joists.

Measure the new hole from where the flooring stops and determine the distance to where it picks up again. Measure then from joist to joist.

Cut your plywood to the measurements. The piece should fit snugly into the area you previously cut out.

Nail the piece of plywood to the floor joists. This should provide you with a good and sturdy floor where the bad area was.

Tips & Warnings

  • You can cut out the flooring laminate and lay down in the bad area. The laminate used has an adhesive backing that will lay flat down and stick to the floor. If you don't have matching laminate, you may have to redo the whole floor.
  • If you are replacing a carpeted floor, fold the carpet back to the bad place in the floor. The carpet is actually ran to strips that sit just under the molding at the base of the wall. You can pry up the carpet and roll it back until the bad floor is exposed. Roll the carpet down to the strip when done.
