Joe & Lisa - excellent!!

Joe was the fourth technician (we had tried two other companies) to come out to fix our problem and he was able to resolve it immediately. We are very grateful! He was professional, did a good job of explaining, and most importantly resolved the problem! Lisa also did a great job of keeping me updated. We will definitely call Guardian again.


Response from Guardian Fire Protection Services:

Amy, thank you so much for such a positive review on our company and the satisfaction you got from Lisa in the office and Joe on-site resolving your problem. We look forward to continuing service on your fire protection systems. Regards, Scott Agge. President

Great service, when they get there.

Technician did not come for the original date of either of my last two appointments. One just never showed up, the other called to cancel that morning. Great service when they finally got here, but its frustrating to constantly have to adjust the schedule, particularly when engineers from the building are involved too.

Thank You for Prompt & Personal Service

Joe Haines took the time to explain our sprinkler head problem in detail so that we would understand. It seems he found a low spot in the dry system branch piping causing water to accumulate at the end of our loading dock line. He recommended installing a drum drip which we are doing as soon as possible. We have been working with Guardian Fire Protection for over 15 years and are always completely satisfied.

Great service, was on time, and hussled to get me back in service.

The Job was done right and he was willing to follow my instructions, It was important to me not to have an alarm after completing the repair, He was able to insure this did not happen, He was very professional at all times.

Great, professional service

Came out to handle several major issues on a Saturday night of a holiday weekend. Did the job right and stayed until it was done. True professionals.
