I have a couple of customers with some dead spots in their lawn. They've asked me to replace it and I'm struggling with how much to charge. Mostly, they have another company fertilize and pest protect and excess chemicals have left certain spots dead. For one customer, I pulled up about a 4ft by 4ft section of St. Augustine and replaced it. The sod cost me under $7. I told her I'd bill her when I bill for monthly lawn service. It took me a total of 15 minutes to pull up the old and put down the new and about 30 - 45 minutes of driving time to go pick up the sod. If I'm looking at billings for hours and cost of supplies, I like to make at least $20 - $25 an hour so I would bill $27 - $32. Does this sound too high? Too low? I have more customers with the same problem and pass by houses all the time with dry/dead spots and it's really easy to fix. I'm just trying to get an idea what I should charge her so in the future I can just measure the area and spit out an estimate based on square footage for the next person that asks me for a quote. What do you guys think. Thanks in advance.
