Tim Kapottos deserves more than 5 stars for work “above and beyond” upgrading my Guardian alarm system in the fall of 2025. He is an expert technician, a great problem solver and a genuinely nice person. The upgrades were expected to be relatively simple, but turned out to be more complex. Tim had to solve a number of unexpected problems to complete the work, and he worked methodically to solve each one. He also took the time to explain what was happening. The next time I need a Guardian technician, I hope it’s Tim (or someone he trained).
Kevin H.
Tech was excellent, even cleaned up after he finished.
Response from the owner:Thank you for sharing your experience, Kevin! We're glad everything went smoothly.
