We've Been Protecting Lehigh Valley Families and Businesses
for Over 80 Years

Four Seasons Security is a division of Deiter Brothers - a family-owned, Lehigh Valley based company that has been serving local families and businesses with complete heating and cooling services since 1929.

Because we have been protecting thousands of customers from winter's cold and summer's blistering heat for more than seven decades, it's a natural outgrowth for this to extend to the protection of property as well.

Unlike the large corporate security firms based elsewhere in the U.S., Four Seasons Security is headquartered here in the Lehigh Valley. Your community is our community. We know every town, every street, every neighborhood.

The Deiter family built Four Seasons Security with the finest security professionals and technology available in the industry. And every installation and service we deliver is backed by a local company with a long history of caring for customers. For Security You Can Trust...Trust Four Seasons Security and Deiter Brothers.
