Ridges or lines showing through the floor.

A flooring contractor should map and sample the floor, and each layer's maker and installer should take any claim.

Customers put it like this

  • I can see the plywood seams through the vinyl
  • ridges in the new floor
  • outline of the patches is showing
  • bumps under the sheet vinyl

Homeowner? These are the questions a good technician will ask you. Having the answers ready makes the first visit count.

  1. What covering is it, and what is under it?
  2. Do the lines make a grid, or follow something else?
  3. Was it laid over an old floor?
  4. Did other trades work on the floor after install?
  5. Who owns the floor, and can a sample be lifted?
