INTERIOR DEFECTS Defects in Mobile Homes

Mobile home wall opened for insulation (C) Daniel Friedman

Our page top photo shows a badly-sagging mobile home roof and a makeshift repair that the occupant has provided to protect against mobile home roof collapse during heavy snow loads. Ver.3.5 - 04/25/07, updated through 2012 - Steve Vermilye, New Paltz NY and Daniel Friedman, Poughkeepsie NY, Hudson Valley ASHI Chapter Seminar, Newburgh NY, January 4, 2000, NY Metro ASHI Fall 99 Seminar, Holiday Inn Crowne Plaza, White Plains NY, October 2, 1999.

  • 32% of mobile homes report problems with windows or doors (C. r. survey)
  • Hardboard floors - get wet, toilet falls through; plywood preferred; check especially floors at baths, kitchens, and below windows and doors
  • Walls: paneling or drywall, typically over furring or 2x3 or smaller studs in older mobile homes; often insulation has become wet from leaks at the roof edges and around windows. See MOBILE HOME INSULATION
  • Windows: often single-glazed, glued or screwed frames (leaky); welded vinyl perform better; caulking often missing between window frames and sheathing (water damage) - same at doors; Caulk at door and window gaps (from factory) may break during transport;
  • We often find floor rot below leaky windows
  • We often find windows that are not operable, including unsafe egress in case of fire - windows in sleeping rooms must be operable to open for fire escape in emergency
  • Be sure to check flooring in outside water heater closets - prolonged leakage often leads to rotted, collapsing floors and can bring insects in to attack the structure. See MOBILE HOME STRUCTURAL DEFECTS

In the past few decades (to 2006), "trailer" manufacturers have considerably improved the quality of construction of such homes. The national manufacturing and building code standards for these structures have also been improved. Perhaps in part to escape the less than wholesome image of "trailer", manufacturers use the term "mobile home" to describe what is usually larger and better made home than "trailers" of old, though perhaps with similar materials.

Mobile homes are built in a factory and are designed to be moved (once and uncommonly, perhaps once again) on its own wheels attached to its own frame to a site where a foundation is prepared and connections to utilities are made. In the U.S., states have regulations about the siting, foundation, steps and entry, wiring, plumbing, tie-downs for wind and storm safety that apply to these homes. Some examples of mobile home regulations for New York State are this website. Individual state regulations will vary - you'll want to see what your state requires. Even within states regulations vary as wind and weather conditions do also.

Examples of mobile home improvements include stronger overall wall and roof construction, less leaky roof covering, and windows that are less notoriously leaky. In addition newer mobile homes have, for fire safety, bedroom windows that can be pushed out to a wide opening for emergency exit in case of fire - an important safety improvement.

Usually building departments grandfather in older structures, but sometimes they will insist that certain life-safety improvements be made, for example if an older mobile home is being brought to a new site in a new community. If this is the case one or two windows may need to be replaced to provide this important safety improvement.
