A dripping faucet almost always means a worn seal inside it, not a loose handle. Modern faucets use a cartridge, ball, or ceramic disc mechanism to control flow, and any of those wears out over years of use the same way a car part does, letting a small amount of water past even when the handle is fully closed. Tightening the handle harder doesn’t fix a worn internal seal, and can actually strip the mechanism faster, which is why the same drip often returns within days of a DIY tighten.
The fix is replacing the specific worn part, cartridge, washer, or disc, matched to that faucet’s make and mechanism, which is usually a straightforward repair rather than a full faucet replacement. We carry the common cartridge types on the truck, so most repairs are finished in a single visit rather than requiring a return trip once the right part is identified.
