I normally informally tell my customers that we Warranty our hardscapes for two years....and I've never had a problem or even ever had to go back to fix anything but I just finished a paver patio and the customer has been the worst client we have ever dealt with...just real high maintenance and he is now saying he wants a written warranty on the pavers....never had to write anything like this up....anyone got any suggestions on the conditions, number of years, etc??? Thanks in advance for the help!
