Giovanni did a great job for me. Replaced a sprinkler controller and diagnosed other problems to severed cable. Once he completed his work, the sprinkler system is working as expected. Will also add that he was very punctual and responsive I highly recommend him

Details: Residential • System won't turn on • Timer does not work

Giovanni Altamirano is a true perfessional. He received my request for a quote and came quite quickly. He assessed the problems and gave me a reasonable quote regarding the amount of repairs were needed. We set a date. He arrived promptly, started the repairs and completed everything in a timely fashion. After the completion of the repairs, he showed me each repair and explained what was needed. Let me say this, it's been a moment since I had work done on my home where everything that was done was explained to me. Giovanni is an exceptional businessman. I highly recommend using his company. His main goal was to do the job well and make sure that I was pleased with his work. Kudos Giovanni, I will use your company for all of my irrigation issues.

A List Irrigation came over the same day, looked at the leaks, gave a fair quote, and did the work quickly on the same day. Very nice gentleman who talked me through the whole process, what was needed, gave some options, and then immediately completed the requested work. He even gave options for things to consider adding later. Very happy with his work.

Details: Residential • Sprinkler head is broken • No water to one area of sprinkler heads
