We had our entire backyard drip system re-done on a large lot. They showed up early. They were friendly. The work was well done. They worked through a couple of "curve balls" from an old underlying system, including fixing a cracked pool pipe that was unrelated to their job. The cleaned up all the work and left the yard in great condition. And the final bill was exactly what they quoted. I will not only use IRS again, but I will recommend them to anyone that needs work on a irrigation or lawn lighting project.
