The answer to 'how long does leak repair last' is that the longevity of a leak repair can vary significantly depending on the type and location of the leak, the materials and methods used for the repair, and how well the repair was executed. Generally, a well-done leak repair using quality materials can last anywhere from 5 to 15 years or more before needing to be addressed again. However, some repairs may only last a few years, especially if the underlying issue that caused the leak is not properly addressed.
It's important to have a professional plumber diagnose the root cause of the leak and perform a thorough, high-quality repair to ensure it lasts as long as possible. Factors like the age and condition of the plumbing system, water pressure, and environmental conditions can also impact the longevity of a leak repair. Proper maintenance and prompt attention to any new leaks can help maximize the lifespan of a leak repair.
