Cement Masons & Concrete Finishers Salary in District of Columbia

Cement masons and concrete finishers in District of Columbia earn a median salary of $60,860 annually ($29.26 per hour), which is $6,200 above the national median of $54,660. Entry-level workers (10th percentile) start around $42,950, while experienced professionals (90th percentile) can earn up to $71,130. The pay difference of $28,180 between top and bottom earners reflects variations in experience, union membership, and project types. DC's high cost of living (17.2% above national average) means the adjusted purchasing power equals about $51,928 nationally. Union membership through OPCMIA (Operative Plasterers' and Cement Masons' International Association) typically provides better wages and benefits. Federal construction projects in DC often pay prevailing wages, boosting earning potential. Specializing in decorative concrete, structural work, or industrial flooring can command premium rates. The job market remains strong due to ongoing infrastructure projects and urban development throughout the Washington metro area.

In District of Columbia, most cement masons enter through apprenticeships or on-the-job training, with over 51% having no formal education beyond high school. The typical path involves a 2-4 year apprenticeship program through OPCMIA Local 891, which covers the DC metro area. Apprentices start at 40-50% of journeyman wages ($11.70-$14.63 per hour) and receive raises every 6 months, reaching full wage upon completion. The program combines 144 hours of classroom instruction annually with 2,000 hours of hands-on training covering concrete mixing, finishing techniques, form setting, and safety protocols. DC requires contractors to be licensed, but individual masons typically don't need separate licensing. However, workers must complete 10-hour OSHA safety training for most commercial projects. The DC Department of Employment Services partners with local unions to provide pre-apprenticeship programs for those without construction experience. Many apprentices find placement through the Washington Building Trades Council. Alternative entry involves starting as a concrete laborer and learning through mentorship, though this path typically takes longer to reach full wages and may lack comprehensive technical training.

The $28,180 gap between the 10th percentile ($42,950) and 90th percentile ($71,130) primarily reflects experience and union status. Entry-level workers and those in non-union positions typically earn in the lower range, while experienced union members command top wages. The 75th percentile at $63,280 shows a smaller jump from the median ($60,860), suggesting most experienced workers cluster in this range. Top earners often work on federal projects paying prevailing wages, have specialized skills in decorative concrete or industrial applications, or hold supervisory roles. Union membership through OPCMIA Local 891 significantly impacts earnings, with union workers typically earning 20-30% more than non-union counterparts. The compressed range between 25th ($51,600) and 75th percentiles indicates relatively standardized pay scales, likely influenced by prevailing wage requirements on government projects common in DC.
