kieffer construction

I returned home from work on Tuesday evening (2nd day of project) to find my aluminum siding ripped from the back of my house which was totally unnecessary and caused damage to the siding. I had outlined the opening for the patio door before work which should have been cut out and the base plate could have been attached directly on the siding. (Aluminum siding goes on from the bottom up which means it must be removed from the top down to avoid damage. Any qualified contractor would have known this. The patio door was installed with no header and when I insisted he remove the door and do it right, he walked off the job and never returned. I had two independent contractors check the workmanship and the both agreed, the door needs not only a header but also a bottom plate and jack studs on both sides of the door, non of which was installed. Just nail the door in the opening and try to cover it over before somebody sees the shoddy work. The deck looked like it was build by amateurs, improper deck screws were used and the balusters and top rails were nailed on with a nail gun. The angle cuts weren't true and were filled with saw dust and dirt to cover the bad cuts.
Mr. Kieffer left the job (unfinished) on Monday morning, after showing up 3.5 hours late (3 days past his promised finished date), I thought to get more lumber to redo the patio door right, but he never came back.
I hired a qualified contractor Mark Kunkel (who really does have over 30 years of experience) to repair the damages to the aluminum siding plus remove and reinstall the patio door proper
Now I get a phone message earlier today from Stan K. claiming I broke the contract and he is calling his attorney in the morning.
I had issued another check for an additional 25% (against my better judgment) when he asked to for the unpaid balance in full promising I could trust him to finish the job and when Stan stopped work on Monday, I stopped payment on the second check the following day. (after it was clear he had no intention of returning). Guess we will have to let the Judge decide... ( a picture is worth a thousand words and I took lots of pictures). Plus there are plenty of eye witnesses!
