Marcia: You might first contact your HOA to determine if the rail is HOA responsibility or yours. If your responsibility then a fencing contractor would be the appropriate pro. Concrete cleaning would be a different pro, possibly a handyman or concrete restoration pro. You can call us to get started with a local fencing pro at 855-494-5972. Or you can search for local pros here: https://porch.com/walled-lake-mi/contractors Thank you.
