I just had my cement patio replaced with stamped concrete. I am considering drilling and installing the brass anchors myself. I've read some old threads on this, but am wondering if there is anyone with recent experience or tips? Should I do it or let the pool company install them. I believe there are a total of 35 anchors. Their price was around $550. I do not want to use the flanges to cover the outside of the holes, so will need to be very careful drilling to minimize chipping. Thoughts?
