Get a company to come out and do lead testing. They will give you the results, recommend abatement contractors, and maybe give you some tips and recommendations. Where I live the people that do the testing are required to be different from the people doing abatement. (And once the abatement is done you can get the people that did the testing to come back out again and officially verify that the housing unit meets lead safe standards.) But US states differ in some of the details here.
