well, i had my irrigation system put in and have a few issues with it. my yard here (austin, texas) had a lock of rock underneath so instead of 1 to 1 1/2 days they needed 3 full days to complete it. but now i have rock on top of my grass instead of under it. can i expect them to clean it up? they did remove rocks larger that fist size but there are still a lot of smaller ones laying around. i can just see me or the kids running around and stepping on rocks all the time. also i am worried about futur lawnmaintenance? aren't all these rock going to create a problem with mowers and weedeaters? also the rain sensor was installed on the fence fairly close to the house. will not the run off of my roof mislead the sensor (we have no gutters)? the sales guy told me my yard will look as good if not better once they are done and that is definitley not the case just now. am i expecting too much? i have not had the final inspection and i still owe them the remaining 50% of their money. any suggestions on how to handle this would be appreciated.
