Contractors for Hire
When hiring any contractor, it’s always a good idea to get at least three bids. If there is a large difference between two bids, find out why (look at the labor hours, material etc.). A good rule of thumb: If it looks too good to be true, it probably is.
- Ask for names of past customers and call them for a reference. Find out how long the contractor has been in business. Call the Better Business Bureau to see if there are any complaints filed against the contractor before you hire!
- Call your local health/building department’s plumbing division to see if your job requires a permit and inspection.
- Counties are not permitted to license plumbers, but Hamilton County Public Health does require a $10,000 performance bond for all contractors installing plumbing. This ensures plumbing jobs are completed and installed to code.
- If you want to assure the contractor is a licensed master or journeyman plumber, you must ask to see their journeyman or master license from one of the surrounding cities such as City of Cincinnati, Middletown or Norwood, etc.
- If a contractor does not want to get a permit, that should be a warning sign that something is wrong. An honest contractor should not hesitate to have an inspector see his or her work.
