After an attempt to break into my house I needed to change the front door locks, so I called these guys and was able to set up an appointment for the same day. Michael arrived exactly at 2PM as it was scheduled and he installed high security Mul-T-Lock deadbolt, this outstanding lock is graded with ANSI 1 grade level which poses anti pick or bump qualities. Michael was very professional, answered all my questions patiently and did an excellent job. I am very satisfied and grateful for their service, highly recommended!
