Hello, my contractor went over allowances and estimates; for example, he put in 5K for counters, and is charging me 10K; estimated electrical to 1.6K, and is charging 8K. Put allowances for shower doors at 2.8K, and charging 4.2 K (on stuff he ordered). Also, he claims a lot of small adjustment made during the work added to the expenses, but did not provide me with a change in order. He did provide change in order in writing for certain items (eg upgrading to metal beam) and I have no problem with that, because I approved them. But his final bill came at 30K over the contract, and only about 12K were approved by me. What is my recourse here? He also took 6 mo for a 2 mo project, 2 mo based on his estimate and on similar projects in the neighborhood...
