Concrete block wall assemblies Typical costs for standard natural gray medium weight masonry block walls including blocks, mortar, typical reinforcing and normal waste. Foundations (footings) are not included. See also individual component material and labor costs for blocks, mortar and reinforcing on the pages that follow. For more detailed coverage of concrete block see the National Concrete and Masonry Estimator at http://CraftsmanSiteLicense.com.

The figures above are from a time and money saving construction cost manuals from Craftsman Book Company. Over 50 cost estimating databases are available and all come with the popular National Estimator program.

National Estimator helps you compile estimates and bids for any construction project

National Estimator lets you use these costs to create estimates for new construction, repair and remodeling, commercial and industrial projects. Copy and paste and anything you see here into your estimate. Then add overhead and profit and print the bid – or turn your bid into an invoice that goes out in a window envelope. It’s quick, easy and flexible.
