The cost to replace a kitchen faucet cartridge will also depend on whether you hire a professional plumber or do it yourself.
In some regions, the labor cost for a simple faucet cartridge replacement may be a fixed hourly rate, while others may charge a flat fee for the entire job. On average, you might expect labor costs for a kitchen faucet cartridge replacement to be in the range of $50 to $150.
If you want a more accurate estimate, I recommend contacting local plumbers or handyman services in your area to get quotes. Make sure to describe the details of the job and ask for a breakdown of the costs involved. Additionally, you might want to inquire about any potential additional fees or charges to avoid surprises later on.
