Construction don’ts-Covering Weep Screed Over is a Common Construction Defect Says Expert...

When a homeowner files a complaint about a contractor to the California Contractors License Board, an industry expert is dispatched to the site to assess the issue and determine whether the work was performed up to standard. 

Scott Cohen is an 11-year member of the board's Industry Expert Program and he's filled a book he titled The Candid Contractor with a decade of construction defect files from his notes. "These are not just mistakes I found in the field from other contractors, but mistakes we made in our own business so we can all learn from them," says 
Cohen, president of The Green Scene in Northridge, Calif.  

The complaint files run the gamut, but Cohen sees these three mistakes the most. 

1. Covering weep screed. The purpose of weep screed is to drain moisture from porous walls, such as stone, stucco and wood. When landscapers make the mistake of putting soil directly up to weep screed, they don't allow water to drain away from the walls. "This can sometimes introduce water into the walls," Cohen says. "So that creates moisture that can't get out of the walls, then you have mold issues, and those can be a big deal."
