“My husband and I were concerned about safety for ourselves in our home. I had called and made an appointment for David to come to our home for a consultation. He arrived on time and was very aware of our needs and concerns. He recommended a home security system that we could monitor from our phone while we were away. When the installation date was made, I had another appointment to attend. David stayed with the installers and occasionally sent me pictures of my two dogs, letting me know they were taken care of.

David was sincere, professional and kept his word of keeping me informed of all appointments, following up with additional information. You normally don’t find people staying on time, let alone following up with you when you live in Sussex County.

After an excellent experience , my husband requested his services at our own business, installing surveillance cameras.  Again, the service was superb and David made sure our needs were met.  

I let all my acquaintances that ask about home security alarms about David Mueller and would highly recommend Alarm Engineering.

Sincerely,
Sandy Chandler”
