    Castle has been providing excellent coverage at a fantastic price for years. They are over the top helpful with all my multi-unit needs.

  • David M. about 2 years ago

    Long time great service passed down from the elder (Jack Castle) and still handled by the siblings in a fantastic well organised up to date operation!

  • Laurel N. about 2 years ago

    Very helpful. Made sure my small business got the insurance I needed and only what I needed. Great about answering questions and doing research on my behalf. Super easy to work with them. Would recommend to everyone.

  • Steve F. over 2 years ago

    I like the combining 7 units together and receiving a better rate. Insurance costs are important when owning apartments. We also like your easy service.
