Verify license and insurance
Ask for proof of license and proof of insurance, and check it independently. LeakFix Oak Park is an information and connection service. All contractors are independent, and it is the homeowner's responsibility to verify that the contractor has the license and insurance required for the work.
Ask about methods and tools
- Do they use non-invasive tools such as acoustic listening, thermal imaging and moisture meters?
- Will they start with a meter test and isolation testing?
- Will they open walls only after pinpointing?
Permits and Village rules
