So Far So Good!
Len and Keystone was recommended by a neighbor. Len came out to the house and made great practical recommendations to suit my needs without selling me the farm. Made a few adjustments after the onsite visit without any hassle. Jen in the office was helpful and friendly too. Looking forward to the new system.
Very reliable and professional!!
Len and his staff respond almost instantly to inquiries. I’ve had no problem with the system since it was installed 4 years ago. Neighbor has DIY system that always has issues. Tech just installed additional sensors. He was friendly, attentive and professional. Call center responds immediately when alarm activated.

I needed someone to come out quick and install a fire alarm. They worked with me and came out the next day! They also called me when they were on there way which was great!
My mom was feeling sick and forgot she was cooking soup. Her pot melted and house filled with smoke. The alarm Lenny Weiner installed alerted your company and they called fire dept. and saved her life. We are forever grateful for your service and company!
