Seal It Solutions No Longer In Business

I hired this company to seal windows at our office. 6 months later their work is leaking. I call Natalie and she tells me Robert will come by to take a look, he never showed up. I called again and again, finally he came, took a look and said he would come back to do the job. He never came back! I called and called, and finally I got through to Natalie who told me that the leak is not their problem, I explained this is not right because its the window they sealed and guaranteed. Robert calls me, yells racial slurs and profanities and hangs up. I don't recommend this company, even if they offer to do work for free or cheap. Bad management and work ethic.
