ESI Security History
Tacoma area customers are a result of working with ESI Security
When Dave Taylor founded a small locksmith company called Edgewood Security & Lock in 1990, he had no idea it would one day become one of the largest and most reliable security companies in the State of Washington. As his business grew, Dave saw a need for high quality security solutions that could better protect his customers.
He knew that if he could offer world class systems at affordable prices, and combine that with excellent customer service, business would boom. Dave was right, and ESI Security is now known throughout Washington as the company to turn to for high quality security solutions.
Today ESI Security services all of Washington with two offices, one in Eastern Washington and one in Edgewood. ESI currently holds both a General Contractor license as well as an Electrical Contractor license for the State of Washington.
