I have a sunken patio at a rental property that needs a fence around it for safety purposes.

30′ of fence total, with one 3′ gate.  I hire a fence compancy (in business since 1995, supposedly) to install vinyl coated chain link.  2 guys (one being the owner) come out one day (I meet them there and give them my cell in case there are any issues) and set 3 posts (two end, and one corner).  I notice that the corner post is about 5″ out of line from where I showed him I wanted it.  Try to reach him on his cell phone:  voicemail maxed out with messages.  Comes back a day later to set the two line posts.  I finally get a hold of him and ask him why the corner post is out of position.  Says that there was a piece of concrete and he wasn’t going to chip away at it.  I pull the corner post and one line post myself, take a hammer drill and cold chisel, and break out the offending concrete.  Reset both posts myself, in poisition, plumb, and in line.

Now, he has 5 posts to install on a brand new concrete slab to make up the third side of the fence, and the gate opening.  I snap a line to show him exactly where the posts should be located.  I’m away for a week, come back expecting the work to be completed, and find three posts “installed”.  Each post has a 4″x4″ base plate with four holes.  Each of the posts is fastened with anchor bolts that have been beat into place:  two are bent over like a nail, one is sheared off at the concrete, others are at an angle.  Two of the posts wobble badly, all three are out of plumb.  One is off the line by an inch!  I see this (on my brand new friggen concrete slab, no less!), and I am really pi—ed!!

I call him and leave a message saying that I’m disappointed in the fact that the job isn’t complete, and in the quality of the workmanship.  He doesn’t call me back, so I call him again the next day.  This ignorant shlep has the cojones to tell me that there’s nothing wrong, that I’m too demanding, and that he was nervous working because I didn’t like the fence posts that were out of line.  I tell him that I’ve been in construction for the past 20 years and have never seen or installed anchors that look like those do.  I’m waiting for him to blame his status in life, his realtionship problems, and the weather on me, too.  I ask him if he even used a hammer drill, and he replies that he only does 4 concrete jobs a year.  That’s his excuse for screwing up the job.  I’m not giving him the chance to finish this job (cause he’ll only frig it up more), and I’ll be living with a few extra holes in my brand new patio, too.  I’m meeting him tomorrow at 1:00PM.

I only paid 50% down, so I’m gonna boot him after he leaves me the rest of the material.  Or I’ll be happy to see him in small claims court court if he refuses (I have many digital pics, and a concrete contractor who would be happy to accompany me).  I’ll conduct an anchorbolt installation on a concrete block in the courtroom, if I have to. 

My question:  I have to remove all three posts and 12 anchor bolts (3/8″ dia).  Is it possible to remove RedHead anchors from concrete –_the type with the long sleeve, not the type with the small ring at the base of the bolt?  I don’t know how long these bolts are, but I suspect that they are not embedded deeply into the concrete.  I was hoping if I could remove them, then I could enlarge the hole (straighten it, whatever required) and use 1/2″ redheads.  Any suggestions would be greatly appreciated.
