nice site...as for SEO, I'd transpose your title tag so that X Laundry goes after the | symbol. Didn't look at much else, but that's a common mistake I see with a lot of client sites. Best of luck!
Don't bother disavowing...start a new site. People get hung up on the disavow process, but it is rarely effective in my experience.
I'd also NegSEO them back...why would you just let them wail away on your site without fighting back? A dose of their own medicine will teach them to not mess with you again.
