Hi there, I’m looking for a reliable tradesperson to diagnose and repair a leaking faucet under the kitchen sink. The issue started recently and seems to worsen after use. I’d like a professional who can identify whether it’s a worn O-ring, cartridge, or valve and replace the faulty part. Please include parts and labor in your quote, and let me know any preparation I should do (e.g., turning off main water, clearing the area). I’m hoping to have the repair completed this week between 9:00 and 17:00. If possible, please bring standard replacement parts and tools. Thanks!
