Greg was very responsive and came within a day to see what we needed. They scheduled to come out a week later, but ended up coming sooner. They were able to tie our current irrigation into our well and did a fantastic job. They were very friendly, took their time and fixed the yard back just as it was!! They are very knowledgeable! I’d highly recommend them and will use them if we have future issues with our irrigation!!

These guys were top notch! They were timely with their response time to get our initial appointment scheduled & able to repair quickly. We are so excited to have our sprinkler system working again after looking for a variety of other companies to actually show up to look at them for over 3 years! Luckily, my Google search found GMG irrigation this time.
