According to Craftsman, construction costs are beginning to move up. Here's what they had to say in the "about this book" section of the 2015 "National Renovation & Insurance Repair Estimator":
"Since 2008, overhead and profit margins for many restoration and repair contractors have been slipping. Material cost increases - primarily pushed higher by rising fuel costs - have often been partially absorbed by contractors working to remain competitive. Contractors have also offered small labor increases to keep skilled workers and many have absorbed some of those costs as well. Last year, as the economy and the construction landscape improved, this trend began to change, and in the second half of 2014 contractors started to recover some of the costs they absorbed in the previous seven years. We expect this trend to continue in 2015, and to see larger wage increases offered to key employees."
