When a Dripping Faucet Becomes a Bigger Problem

Next steps (at a glance)

If you only do 3 things:

  1. Pay attention to how often and how fast the faucet drips.

  2. Check for moisture or staining around the fixture.

  3. Address persistent drips before they worsen or spread.

Urgency level: Low → Medium
(Becomes High if leaks worsen, water damage appears, or dripping is constant.)

Short answer

A dripping faucet isn’t just annoying—it can signal internal wear, hidden leaks, or pressure issues. Over time, even a slow drip can cause fixture damage, cabinet moisture, mold growth, and higher water bills.

Small leaks tend to grow, not stabilize.

Why dripping faucets matter

Faucets rely on seals, cartridges, and internal components that wear down with use. When those parts fail, water escapes even when the handle is “off.”

Because leaks often stay contained at first, damage can happen quietly behind walls or inside cabinets.

Common causes of dripping faucets

  • Worn washers or cartridges

  • Mineral buildup from hard water

  • Loose internal components

  • Corrosion inside the valve

  • Excess water pressure

A drip usually means a part is no longer sealing properly.

What a drip usually looks like over time

Early stage

  • Occasional dripping after shutoff

  • Drips stop and start

Progressing

  • Steady drip or thin stream

  • Water spots around the fixture

  • Faint moisture under the sink

Advanced

  • Constant dripping

  • Cabinet swelling or staining

  • Mold or musty smells

  • Damage to countertops or flooring

The longer a drip continues, the more likely damage spreads beyond the faucet.

Typical lifespan context

  • Faucets: often 15–20 years
    Early failure clues: persistent dripping, stiff handles, corrosion

  • Cartridges and washers: wear sooner
    Early failure clues: drips that worsen over time

Dripping doesn’t always mean full replacement—but it shouldn’t be ignored.

Warning signs to take seriously

  • Dripping that becomes constant

  • Water stains or bubbling under sinks

  • Musty or damp odors

  • Handle movement that feels loose or gritty

  • Moisture spreading beyond the fixture

These signs suggest more than a cosmetic issue.

DIY-safe checks you can do

These checks are generally safe for homeowners:

  • Confirm the drip continues when fully shut off

  • Look under the sink for moisture or staining

  • Dry the area and check again after use

  • Note whether pressure feels unusually high

Avoid disassembling valves if you’re unsure of shutoffs.

Maintenance that actually helps

  • Address drips early before parts degrade further

  • Clean aerators periodically to reduce mineral buildup

  • Pay attention to pressure changes

  • Keep cabinet areas dry and visible

Early fixes are usually simpler than repairs after damage.

If you don’t want to call a professional yet but want to stay safe

Prioritize these:

  • Stop ignoring persistent drips

  • Monitor surrounding moisture carefully

  • Avoid overtightening handles, which can worsen wear

If the drip continues or worsens, professional repair is the safest next step.

Common mistakes

  • Assuming a slow drip is harmless

  • Waiting until water damage appears

  • Overtightening the handle to stop leaks

  • Treating recurring drips as “normal”

Drips are early warnings, not background noise.

When to call a professional

Contact a licensed plumber if:

  • The drip is constant or worsening

  • Water damage is visible

  • You’re unsure how to shut off water safely

  • Multiple fixtures develop leaks

What to ask:

  • Whether repair or replacement makes sense

  • If water pressure could be contributing

What to expect:
Most faucet repairs are straightforward when handled early. Delays increase cost and disruption.
