Speaking of cost, you might be wondering how we ended up going from $23,000 to $27,000. Well, let me break it down for you. The original estimate covered the cost of the turf, which is relatively inexpensive per square foot, and the labor involved in creating and laying the turf. That also went towards the gravel, drain pipe, fabric, and some other minor improvements we made on-site. The additional cost was added to cover the last-minute addition of the gator base. The material itself cost us roughly $2,800, which we charged directly to the client. We also asked if they would be okay paying an additional $600 for labor to install the gator base, which they had no problem with.
