How to Look

at a House

A blog with answers
to your questions about

Welcome to our blog!
We want you to be an informed homebuyer, and each blog post is a question that we have answered for our friends and customers over the years. Hope they help you make a good choice for your next home.

  1. 2)Steel frame - Corrosion of the steel frame is a common defect and can be problematic when it becomes severe. Heavy corrosion is usually an indicator of a high moisture content in the crawlspace. Many times the detached tow bar is stored in the crawlspace and can be welded back on for moving the unit to a new site in the future.

  2. 3)Piers - Over time the stacked concrete block foundation piers can move out of plumb because of settlement or soil movement. The plastic foundation pads, pier block and wood shims are examined for any cracks, loose areas or other defects. Secondary piers are required to support large openings in the wall framing such as sliding glass doors, at "marriage joints", where sections of the mobile home connect and at exterior walls where the frame is cantilevered. Any temporary piers added by the homeowner or a handyman indicate defects in the support structure of that area and are explored.

  3. 4)Straps and cross bracing - The metal straps, anchors and connectors play an important safety role for the home during high wind situations. The numerous components and installation details are inspected, spacing measured, and documented. The depth of the anchor in the ground, the angle of the strap and how the straps attach to the frame are a few of the details of the tie downs that are examined. Straps that have been cut or damaged, like in the photo at the top of the page, are noted also. For more about the tie-down requirements for mobile homes, see our blog post ”What are the tie-down requirements for a mobile home?”

  4. 5)Belly Wrap - We commonly document damaged openings in the "belly wrap” (vapor barrier) that seals the underside of the floor framing—usually where a plumbing repair has been made. The belly wrap is an important component because it blocks water vapor from entering and damaging the floor framing and sheathing over time. Occasionally we find large areas of damage to the vapor barrier and insulation because there was an opening in the skirting that gave an animal access to the area and an opportunity to pull down the insulation.

  5. 6)Visible a/c and plumbing components - Most of the the electrical wiring, plumbing piping and a/c ducts are not readily visible in the crawlspace because of the insulation and vapor barrier, however we examine what is visible for defects such as open electrical boxes, open electrical splices, leaking or poorly supported drain and supply piping and a/c return lines that are sitting on the grade instead of being properly hung from the framing. Any bulges in the vapor barrier are carefully explored because they usually indicate a plumbing leak that is not visible. And of course, we are always on the look out for evidence and damage caused by termites and other wood destroying organisms.

    For an overview of the ten most common defects found during an inspection of a mobile/manufactured home, see our blog post “What are the most common problems with older mobile homes?”

While we hope you find this series of articles about home inspection helpful, they should not be considered an alternative to an actual home inspection by a local inspector. Also, construction standards vary in different parts of the country and it is possible that important issues related to your area may not be covered here.
