Beware of contractor scams when rebuilding from wildfire damage


Sept. 18, 2023

#23-24

TUMWATER — Disasters like our state’s recent wildfires often bring out scam artists itching to make a buck from homeowners desperate to quickly rebuild or repair their homes.

That’s why the Washington State Department of Labor & Industries (L&I) is urging people recovering from the devastating fires to be sure to hire contractors registered with the department.

L&I requires construction contractors to be registered and have liability insurance, a business license, and a bond to provide some financial protection if something goes wrong with the project.

It’s easy to verify contractor registration at ProtectMyHome.net or by calling L&I at 1-800-647-0982 and pressing 2.

Introduction

The work I do for Building Science Corporation (Joe Lstiburek’s company, for those who don’t know) involves forensic investigations of moisture-related (or similar) building failures—i.e., sleuthing out problem buildings. Despite the fancy name, this typically involves crawling around the bowels of commercial and residential buildings to look at the problem areas and figure them out. They range from sleuthing out strange odors that seem to emanate out of nowhere, windows that leak water during rainstorms, indoor swimming pools with rotting walls, freezer warehouse buildings with icicles growing out of the ceiling, mega-mansions with out-of-control humidity levels that are damaging the art collection, and moldy and wet crawl spaces.

As a requirement of the building codes, Simpson Strong-Tie® joist and truss hangers are tested in accordance with approved
standards which define how to construct the test setup, how to load the assembly, and how to interpret the results. The test
standards and Acceptance Criteria for these hangers, ASTM D7147 and ICC-ES AC13, require that they be tested with a 1⁄8"
gap between the end of the carried member and the carrying member. Therefore, for hangers to achieve the full published
allowable loads, the same conditions must be met in the field, i.e., that gaps between the carried member and carrying
member not exceed 1⁄8".
Testing performed by Simpson Strong-Tie has indicated that joist and truss hanger allowable loads are decreased when larger
gaps are present. The amount of decrease in allowable load depends on the size of the gap, the type of hanger used and the
type and location of fasteners. Figures 1 and 2 below illustrate two ways in which gaps affect performance.
