Hired a landscaper to install zoysia sod, and he billed us for 16,000 square feet of sod...both for the sod itself and for the labor to install it. Had some problems with him, and with the sod...and when another landscaper came by to look at the mess, he told me that he didn't think there was anything close to 16,000 square feet. So...after making a bunch of preliminary measurements myself, and doing some math...I hired a surveyor to come by and survey all the sodded areas. The sodded areas total up to 11, 221 square feet. The difference between that figure and the 16,000 square feet we were billed for is 4,779 square feet. That's a difference of 42.5 percent. I know that it always takes extra, for cutting in, etc. But three landscapers have pointed out that our yard is not complicated...mostly square, with one gentle curve along a driveway...and with only a couple of circles around trees. And they all three state that over 40% extra is WAY too much. (One even stated flatly that "ANY landscaper who charged you 40% extra for this yard is a thief, and was just trying to pad the bill.") They all say that, as a general rule, when they order sod for a project, they order about ten percent extra, and figure that they'll have a little of that left over. Does that ten percent figure sound about right? What's your take on someone charging over 40% extra?
