"Most homeowners take for granted the plumbing services that they receive from their local plumber, but some homeowners actually require more than a plumber's expertise. While some homeowners replace their plumbing systems in specific sections, such as their kitchen and bathroom, others must replace all of the plumbing in their houses at once. First and foremost, a homeowner should hire a licensed plumber who is familiar with all of the house plumbing systems, including where there are leaks and if any repairs need to be done. A licensed plumber should also have the proper tools and equipment to be able to repair the issue. In some cases, the homeowner may be able to perform the necessary plumbing repairs themselves. However, not everyone is comfortable doing this. If you are not comfortable with performing plumbing repairs or replacing piping, then a professional repair company may be able to complete the task for you. Leaking drains and pipes happen more often in older homes were smaller, more cookie cutter types of plumbing were used. Unfortunately, those old systems often did not provide adequate protection from drains and piping leaks. As a result, drains and piping leaks can easily get trapped behind walls and under floorboards, which can create very unsanitary conditions.
