Bathroom Faucet Repair That Stops the Drip For Good

You shouldn’t have to ignore a slow drip at the sink or work around a handle that’s stopped moving the way it used to.

A faucet that drips with the handle closed, leaks at the deck plate, or has lost pressure to a fraction of what it used to deliver is wear that gets worse if it sits, and it can damage the vanity or subfloor while it does.

Bathroom faucet repair in New Jersey is handled by Princeton Air with licensed plumbers who identify whether the issue is in the cartridge, the ceramic disc, the O-rings, the aerator, the supply lines, or the angle stops, and correct it at the source.

The repair is completed so the faucet runs cleanly without dripping, holds pressure across hot and cold, and doesn’t put the cabinet at risk of slow water damage. Call Princeton Air or schedule online today.


Active Faucet Leaks Are a Plumbing Emergency

A bathroom faucet that won’t shut off or a supply line that’s spraying inside the cabinet falls under emergency plumbing service.

A faucet that won’t close, a supply line that’s failed under pressure, or an angle stop that’s spraying inside the vanity is a plumbing emergency and needs an immediate response, not a scheduled appointment.

Princeton Air’s emergency plumbing line is staffed 24/7 to dispatch a licensed plumber for the underlying repair. Routine faucet wear, like a slow drip or a stiff handle, is scheduled through normal service.

Our Tech Dominic was Awesome!! Thank you so much!!
On time. Completed work on all units … Heater, air conditioner, and hot water heater … Within the time frame.
After a few mishaps, Princeton Air came through and got my AC system running when the temperatures are soaring.

Thanks to Will and my technician, Alberto, for getting everything fixed.
Responsive, knowledgeable, dependable, & honest. Thank you for getting out heat up & running!

Update:10/12/18
Chris S got the heat last year and remembered when he arrived today, asked if it had a problem since. He came back to do a PM on the heater and while he was waiting for me to arrive, he opened up the air conditioner to inspect it and saw the coils were filthy. Took out his hose and cleaned them. Then when done, did the heater PM and then โ€œsaid I just want to verify that ringing noise went away. Your house will cool much faster now!โ€ I really like what Princeton air offers, quality and care, diagnose and fix. Not rushing to get to the next job. Theyโ€™re so good I got the year round service plan.

Update may 2025&2026
Maurice is fantastic.
Prompt and knowledgeable. Great technician.
There was an urgent need for a mold problem to be handled in a bathroom. They quickly identified the problem, tested the seriousness, and took care of it – in a very timely fashion. They communicated with me all along the way so I could fully comprehend what was going on. All the people were very knowledgeable, pleasant and accommodating. My experience with them was excellent, and I would highly recommend them.
Eric M. was prompt, professional, courteous and quite helpful. I become a better consumer when I understand the problem & possible solutions. Eric was willing to answer my questions and made me feel secure that he would follow up to help fix our problem.

New review: 2/6/2018
Notice a problem with the humidity in my home, called and got a service appointment in the same day. Will D came out and sure enough, confirmed there was a problem, explained what exactly was happening, why it was happening and how to check that it was working correctly. His demeanor was pleasant, he was professional and seemed to be quite knowledge!
Great service. Domenic was so helpful and explained everything done.
Jermaine Richmond was very knowledgeable and explained my plumbing issue throughly. Thank you.
Pretty micron air was quick to fix my sewer
Friendly and efficient. Quick response service
Eric did a fantastic job
Installation of water heater hvac and furnace – very professional and process oriented –
The technician who came was Jonathan Redondo. He was very knowledgeable and did an excellent job! I would highly recommend him .
Christian and Mike were professional, thorough, patient, and kind throughout my heating boiler installation.
Always excellent service with McAllister.
Robert came to check my 2 carbon monoxide detectors, which were very old. I decided to have him go ahead and replace them with smoke detector/ carbon monoxide combination units. He was very polite and efficient .
Jihmy and Asterson did an outstanding job and were extremely professional during a recent installation of a mini split and air handler. They communicated well, kept the house clean and did the job with a level of professionalism and expertise that was refreshing.
Good job
Maurice Gaines who cleaned and serviced my air conditioner was fantastic! He was fast, respectful and very fast with the repairs.

He made me feel like I was getting the full respect and honesty I so needed for something so important and really appreciated the time he took to explain every and answer all my millions of questions. Also Princeton Air communications were fast and accurate , leaving no question unanswered as to timing and confirmation of appointment. Iโ€™m so happy with their staff and with Maurice- heโ€™s a gem!
Thank you!
The young man who came out to fulfill our annual service contract was extremely professional and was very thorough. Although he told us we needed a new ac unit I felt confident that he knew what he was talking about and took the right amount of time in order to make his recommendation. I want him back every year. Unfortunately I forgot his name because Iโ€™m old.

He then had Ricky call us with replacement ac unit recommendations. He was just as professional. He then took the time to visit our condo, take measurements himself and then made recommendations on what size unit to purchase. I really feel he saved us money. He was amazing.

We then were contacted by a gentleman named Steve who was a manager in the service and installation department. Itโ€™s hard to believe but he was just as good as the first two representatives and was an absolute pleasure to work with. He was a true professional and a real asset to your organization. I will always use your company if I can work with this team. Keep up the great work. Thanks for allowing me to spend $8,000.its hard to believe I didnโ€™t even get other quotes because I was so happy with your team.
Water purification system
Recently Princeton Air did a routine maintenance check on our HVAC UNIT. The technician was Dominic McGinley. I must say Mr. McGinley was outstanding. After performing the maintenance and evaluation, he sat down with us and explained his findings in precise detail. He has also taken pictures of everything he found. Dominic was a pleasure with whom to interact. He was professional, friendly, and extremely knowledgeable. He explained everything in terms that we could definitely understand. He is one of the finest technicians that has ever performed preventative maintenance on our equipment. In my estimation he has all of attributes of a first rate Service Technician. Hopefully Princeton Air just what a valuable asset he is for the company. I certainly hope to interact with him many times in the future.
We recently used Princeton Air to install a new heater. They gave us lots of options, explained each one thoroughly, they arrived promptly on installation day and did a great job. The price was the lowest of three companies I contacted for estimates. Five stars!
Always professional and informative.

Bathroom Faucet Problems Our Plumbers Handle

Drips, base leaks, and pressure drops are the everyday bathroom faucet calls, each tied to a different fix.

Princeton Air’s licensed plumbers resolve the full range of bathroom faucet failures.

You hear the slow drip even when the handles are fully closed. Drips almost always indicate a worn cartridge, ceramic disc, or rubber washer inside the valve assembly. Your plumber replaces the internal component with the correct part for your faucet model.

You see water accumulating where the faucet meets the sink deck. Base leaks come from a failed O-ring inside the spout assembly or a loose mounting that’s allowing water to work its way underneath. Your plumber disassembles the faucet, replaces the O-rings, and seats the fixture properly.

You notice weak flow that’s different from the pressure in other fixtures. Pressure loss at a bathroom faucet is usually an aerator clogged with mineral buildup, a restricted cartridge, or a damaged supply line. Your plumber diagnoses the specific issue and restores normal flow.

You find a handle that won’t turn, spins freely, or has come apart. Handle failures trace to internal stem wear, missing set screws, or cartridge issues. Your plumber repairs or replaces the failed component.

You see water staining the inside of the vanity or actively dripping from the supply connections. Supply line leaks come from aging braided lines, failed compression fittings, or corroded angle stops. Your plumber replaces the compromised components.

You notice chipping, pitting, or staining on the faucet finish. Finish damage is usually aesthetic, though severe cases may indicate a fixture that’s reaching end of life. Your plumber discusses whether repair or replacement is the better path.

Frequently Asked Questions

Why does my bathroom faucet drip even when I close the handle tightly?

That symptom almost always means the cartridge, ceramic disc, or washer inside the valve has worn and is letting water past the seal. The fix is usually a quick component replacement.

Is it worth repairing a lower-cost bathroom faucet?

It often is, because the repair part is typically inexpensive and the fix is quick. The exception is a faucet that’s lost its finish badly or has multiple failures at once, where replacement starts to make more sense. Your plumber helps you decide.

Why has the water pressure dropped at just my bathroom faucet?

The most common cause is an aerator at the spout that has accumulated mineral deposits and restricted flow. A less common cause is a restricted cartridge or a damaged supply line. A quick inspection tells you which applies.

Can I replace a bathroom faucet myself?

A DIY install is possible if you’re comfortable with the supply line disconnects, the faucet mounting, and the drain reconnection. Failure points are usually in those connections, where a small mistake produces a slow leak that shows up later. Professional installation is often more economical than dealing with a delayed water damage issue.

How long does a typical bathroom faucet repair take?

Most residential bathroom faucet repairs wrap up in 30 to 60 minutes. Cartridge replacements, aerator cleaning, and O-ring service are all quick. More involved repairs like supply line replacement take longer.
