    After contracting with this company the past few years and firing them I leave the following…read morereview. This company just like most companies in the lawn-care business treat customers with strong distain. They promise far more than the customer ever receives. This company began by agreeing to maintain my sprinkler system. I explained that my system "was" installed by a journeyman that broke off from a company he worked for and began a private company. Unfortunately afterwards it was discovered that he hadn't installed my sprinkler system in the acceptable way of their industry. First time I realized there was a problem was when I had a problem with several of the sprinkler heads. When he came to my home, he began grabbing used sprinkler heads out of a small box that was stored in the back of his small minivan. He told me that he had rebuilt the used heads. Then there was a time when I rented a lawn aeration machine. After I was done and I turned on my sprinkler system, there were a dozen areas that had leaks from the plastic tubing which was not installed far enough below the surface of the lawn. Unfortunately the lawn sprinkler installer had fallen terminally ill. When I began researching sprinkler system companies, Greg Tanzer Sprinkler Company was located on the YELP search site. Even though the site only had a three star rating, I had requested that they come and look my system over with the intention of hiring them. After coming out and reviewing my sprinkler system, they agreed to service and maintain my system. Shortly after I had a problems with sprinkler heads reaching the required areas causing my lawn to have growth issues and flooding in other areas as well as timer issues. The company came out and replaced specific sprinkler heads but charged me for a service call that was explained by claiming the heads were covered but the labor to change them out was not. This was after a contract of over three hundred dollars was paid. When I called to protest the contract agreement, the woman on the line was very nasty and unsympathetic. Another instance of my sprinkler heads not retracting below the ground, the woman who had "no" installation experience merely stated that it was due to one of two components that pump the water but she couldn't explain which one and if after changing one of the two, I would also have to pay for the other pump. Each one costing over three hundred dollars. Another time she blamed the old rain sensor that they never changed out when they took over the system. Another three hundred dollar charge. Each year I asked to split my contract payment due to being retired and the woman gave me a problem. The final straw came when I kept having with the Timer Box losing the settings and once again the woman with zero experience with the system claims that I have to buy another Timer Box. I finally found one of their workers that would work on my system on his free time; however when it was apparently discovered the woman sent another technician out that became enraged and obnoxious, claiming that while discussing the issue accused me of spitting on him (I was at least seven feet away) as well as not speaking a reasonable amount of English. I finally asked him to leave my property and not to return. EVER!

    This company has deceitful and misleading business practices like replacing parts that don't need…read morereplacing, upselling, and overcharging.
