1.Seattle Security Services

Many Seattle security companies are happy to provide the best service when you first hire them. But gradually over time, you notice that the service starts to slide. Less dependable security officers are sent your way. You find it harder to contact management. You begin to start looking for a new security service provider. At Seattle Security Services, it is our goal to never let this happen. If you have been with us for a while, you are even more deserving of getting 100% from us. Our long-term clients have made us what we are, and we value them.

Because customer service is so important to us at Seattle Security Services, we provide direct phone access to management every day, all day, 365 days a year. We are always “on call.” Because providing premium service is core to our values, we supervise our security officers in the field. Our random checks include both physical checks and cell-phone checks.
