Have a customer that thinks we must be dumb or something? Job was to dig out lawn and level it to make it level so they can put a boat on the lawn... we did so. Well about 4 hours into the job, we hit a retaining wall that was 3 feet into the ground. In order to make the lawn level, we had to remove the lawn. We always put in the contract how many hours it will be to do the work, and also if we are to go over the hours, then we will be paid more. Well we went over 16 hours because of the new slope/level of the lawn that we were installing. Also it took 9.5 hours to take the wall out. (hauling, labor, bobcat etc) We then needed 4 tons of topsoil because the existing earth was all clay. So we have 16 HRS extra labor, plus 9.5 with bobcat, 2 laborers and hauling. Extra cost was $750.... plus 310 from previous balance. So $1060 total. Well she wrote a check out for $400 and said that is it until Tuesday until we talk more. I was at her house for 1.5 hours trying to figure out what was going on. Our bobcat operator hit a second wall, showing the customer this she said do not take it out because of the extra work involved. Before we knew about the wall, he hit the wall and the bobcat must have went under the rock and knocked him back up and he hit the deck that is like 2 in away from the wall. Of course we can not help this. He chipped a 2x8 and a 6x6 what that is about $30 IF that? We offered to repair the boards and stain them, she said fine. Now she changes her mind. Anyways, like saying before I was at her house for 1.5 hrs explaining the bill and due to the overages. She was just like so pissed at me! I told her AND showed her in our contract it states that if we hit any hard rock, stone, walls etc that additional costs will be added to the final bill. OK where does it state that you do not have to pay it lol. So her husband called and said we will send a check out for $38.25 and thats it and we are filing a lawsuit for hitting our deck. Dude it is $40 I mean the most if a deck installer would charge if he came out it would be $300! Plus our insurance would pay for it anyways. We are sending a certified letter given 10 days to pay the bill, then we are filing a lien and taking her to the District Magistrate. In our state, that is the procedure. I NEVER filed a lien, only went to magistrate. SO where do I go to file a lien? What info do I need for the state of PA.....? In 05 we had 25k of unpaid invoices from customers, we never filed liens, just took them to the DJ. My ? is how do we file a lien, of course they will sue us for the deck, but really does not matter since we have insurance.
