I subbed out a hydroseeding job this June for a job i was doing. The yard came out nice except for a few large areas. I have tried to contact the other company but he wont return any of my calls. What would you do. the customer keeps asking me to repair the spots. I know that most seeding companies will not guarantee their work for various reasons. Should i just tell the customer to wait a few weeks and I will over seed it for him for just the cost of the seed???
