Can you sue a home improvement contractor in Pennsylvania?

You can sue just about anyone for just about anything. But you need to make a decision as to the "value" of the case. At last check, the jurisdictional limit for this kind of action in Pennsylvania was $10,000. If your wish to do battle for this amount or less, you can make your own case without an attorney, and your contractor will have to defend him self in person. In any case, it is up to you to pull together all the photos, documents and whatever else you'll need, either to hand it over to a lawyer or to present to the judge in a small claims action. You may wish to contact an attorney. They usually are free or modestly priced for a consult. You will be apprised of their rates when you go for your consult. If you really feel you got shafted, you may want to check out arbitration before forging ahead with litigation. There are professional arbitrators who help folks sort this stuff out. Find one and talk to him. Good luck.
