Premium mobile homes have a netting stretched across underneath the belly wrap as a reinforcement, which prevents the gradual sagging between fastener rows that can occur over time. Large bulges in a belly wrap that is otherwise intact can indicate a plumbing leak under the floor. Cutting a pinhole in the bulge tells all.

   We recommend patching any access hole cut in the belly wrap to make a repair under the floor of the home immediately after completion of the repair. A neat trick to simplify closing up the opening after your repair is to begin by cutting an X-shape centered under where you want to work. You will have four flaps hanging down during your repair that can taped back up when work is completed. Both mechanical fastening and a flexible sealant or tape should be used to secure the repair area. The best repair technique is to install a sheet of lightweight sheathing within the belly opening above the hole, mechanically fasten (staple or nail) the torn area to the sheathing, apply a sealant to the edges (mastic, caulk or adhesive tape), then cover the whole area of the tear with a scrap piece of belly wrap that is also mechanically secured and sealed.
