On average, a professional plumber can complete a simple faucet replacement within one to two hours. For more complex or brand-new installations, it may take about seven to eight hours from start to finish. This includes prepping the area to prevent water damage, removing the old faucet, adding new supply lines, and installing the new faucet.
A local handyperson can probably replace an existing faucet. The handyperson cost to replace a kitchen faucet may be less than that of a licensed plumber. However, they may lack the knowledge or experience to modify or work with pipes or other elements of your home's plumbing system.
A typical kitchen faucet can last 15 to 20 years, depending on its quality and maintenance. Proper installation is key to longevity. If you want your kitchen faucet to last longer, hiring a licensed plumber to install it is a good idea.
