Yes, this is considered a beginner-level DIY project, especially for common leaks caused by worn washers or O-rings. While the estimated time is 2 hours, it can vary depending on your faucet type, the age of the faucet, and how easily components can be disassembled. Patience is key, but most first-timers find it manageable.

You'll definitely need a flathead screwdriver (like the Milwaukee 8 in. x 3/8 in. Slotted Flat Head) for the decorative cap, a Phillips head or another flathead for the handle screw, and an adjustable wrench for the packing nut on compression faucets. If you don't have the exact brand, ensure you have appropriate sizes to avoid stripping screws or nuts. Having a small cup for removed parts is also helpful.

Turning off the water supply is the most crucial first step to prevent flooding and allow safe work on the faucet. Locate the shut-off valves directly under the sink and turn them clockwise until they are tight. If your sink doesn't have individual shut-off valves, you'll need to turn off the main water supply to your house, usually found near your water meter or main pipe entry.

The most reliable method is to remove the old O-rings and washers and take them to a hardware store to match their size and material. If your faucet has a visible brand and model number, note it down, as this can help you find a specific repair kit. Many stores also sell universal O-ring and washer assortment kits which can be very useful for matching sizes.
