tree removal

If you got a tree growing next to your shop, house or driveway, pay attention to it and its roots. My neighbor asked me to cut a tree down growing on my property adjacent to our common block wall (that has a crack) we had built and his property line. He said that it was raising his driveway slab and cracking his garage floor as well as the wall. I said Ok and he agreed to pay half, that was very nice of him. So he gets a few quotes from his contacts (he is Latino so I asked him to negotiate a price with his contacts) We agree on a $500 quote given by a guy who was sent a pic of it, and turned down a $650 and a $1500 quote. The $500 guy blew us off so we called the $650 guy and he got him down to $550. That was the good news: The bad news was he was strapped for cash after school supplies and could only give me $200 for the job. OK, so Im in for $350, still lower than my homeowners deductible. The crew shows up 3 hours late and starts digging and chopping this mass of trunks coming out of this root that was cut clean off 5 years ago. 4 hours later the 3 are still digging out this stump and they have not even gotten to the bottom yet. This stump is literally 3 feet wide, they are 3 feet deep and looks like a solid rock after they chopped and chainsawed many root offshoots. Now the guy is telling me that its going to cost more as they didnt expect this much root. Im OK paying them $100 more but now I'm out of cash. They are coming back monday to chop the rest down and grind the stump, but there is damage to my foundation as this monster was growing right next to my foundation wall. It has broken a 10 foot section and pushed one end in 4 inches! The wood frame doesnt look like it was moved, my neighbor thinks the lag bolts may have broke between the foundation and the wood frame, preventing the frame from buckling. Im afraid Ill have to get the insurance involved so they can underwrite the foundation damage and repair or tell me that it is not structural. Im thinking this "tree" has been cut down many times (once by me 5 years ago) but never killed as I cant believe the size of this root, no way this is a 5 year old root, Im thinking like 50....IMGP2812.JPG IMGP2806.JPG
