Review of Suffolk Lock & Security Professionals, INC.

I appreciated that Joe and his team determined what we needed to put our security plan together and worked with our Security vendor to bring this all together. The material was delivered on time, the installation crew was organized and able to work under very strict conditions of safety and concern for our residents, an over all very good experience. I will continue to use this company in the future ,and would recommend others to give them a look.
