No other exterior maintenance contractor can compete with WMS when it comes to large scale civic cleaning & maintenance projects. For more than 30 years we pressure washed and removed graffiti from multiple high-visibility tunnels throughout the city of Los Angeles: LAX/Sepulveda, Van Nuys Airport, 2nd and 3rd Street, Macy Street, Vignes Street and Mulholland Drive. Our skilled employees handled all traffic control, road closures and detours with little disruption and minimal impact on harried Los Angeles commuters.
