“Housing starts appear to have been constrained by weather, labor and financing issues in the second quarter. We will continue to be agile in our operations as the weather improves and builders address these issues. The consensus projection for housing starts for this year is a 25 percent increase over 2012, with starts projected to increase at least another 25 percent in 2014. We will be ready to respond,” Stevens said.
