Need Bathroom Sink Installation? Princeton Air Is in Your Neighborhood

Bathroom sink installs in older New Jersey homes usually reveal plumbing older than the sink.

Supply lines with a decade or more of corrosion, shutoff valves that seized years ago, and drain assemblies that no longer meet code are common findings when an old sink comes out. Homeowners in Edison, New Brunswick, Lawrence Township, and Princeton Junction have worked with us to update the plumbing beneath the sink at the same time as the fixture itself.

What to Expect From Your Bathroom Sink Installation

You should know what the work looks like before any fixture comes out.

Here’s the experience from your side.

Your licensed plumber reviews the existing sink, the counter or vanity it sits in, and the plumbing underneath. Anything worn, corroded, or out of code gets flagged before work begins so the installation goes cleanly.

Your vanity, counter, and floor are protected throughout the work. The old sink and fixtures come out, the plumbing is updated where needed, and the new sink is set with clean connections and secure mounting.

Every connection is pressure-tested and visually checked for leaks before the job closes. You get a walkthrough of the shutoffs, the drain, and what to watch for as the new sink settles in.

Your relationship with Princeton Air doesn’t end at the install. You have a local team with more than 50 years of experience servicing homes across the region, and we’re the ones you call when anything comes up.

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

Installation of water heater hvac and furnace – very professional and process oriented –

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.

Signs You May Need a New Bathroom Sink

Sinks rarely fail all at once.

They show their age in a handful of recognizable ways before replacement becomes urgent.

Hairline cracks in porcelain or composite basins let water seep beneath the sink, damaging the vanity and the floor over time. Once cracks appear, they grow with daily use. A new sink stops the slow damage and gives the bathroom a clean, intact surface again.

Water in the cabinet beneath the sink signals a leak somewhere in the plumbing. Drain connections, supply lines, and shutoff valves all have finite lives, and older installs often reach end-of-life together. Replacing the sink is the natural moment to update the plumbing beneath it, which prevents the next leak from being worse than this one.

Rust rings, hard water buildup, and permanent discoloration that no cleaner touches are a sign the surface has broken down. The basin isn’t just dirty, it’s degraded. A new sink restores the look of the bathroom and makes daily cleaning fast again.

Small basins, awkward heights, and pedestal styles that offer no storage underneath don’t match how most households use the bathroom today. Families with kids, older residents, or multi-user bathrooms outgrow these sinks quickly. Replacing the sink to match current household use is one of the highest-return small bathroom updates available.

When the cabinet or vanity beneath the sink shows warping, staining, or corrosion, the sink above it is usually contributing. A new sink with proper plumbing connections stops the moisture source and gives the vanity a chance to dry out or be replaced. Addressing the sink and the plumbing together prevents the damage from spreading.

Complete Home Services For Your Home

A sink project often connects to other bathroom plumbing work.

A bathroom sink is one part of the larger bathroom plumbing system. Supply lines, drains, and the other fixtures around it all affect how the space performs.

When your existing plumbing system needs diagnostic work or a repair, our team handles it with the same care we bring to installation. Catching a small issue early keeps it small.

Annual service is how a plumbing system hits its rated efficiency and lifespan. Routine attention turns a system that might have lasted 10 years into one that lasts 15.

New Jersey hard water shortens the life of every water-using fixture in the house. A whole-home water softener protects everything from the water heater to the kitchen faucet.

Full bathroom plumbing projects often pull multiple fixtures together, from tubs and showers to sinks and toilets. We handle the scope with one licensed plumber and one schedule.



Schedule Your Bathroom Sink Installation

A new bathroom sink is a quick project with daily returns.

If yours is cracked, leaking, or simply no longer right for the household, our licensed plumbers will install a replacement with clean work and attention to what’s beneath the surface.

Call Princeton Air to schedule your installation.

Bathroom Sink Installation FAQs

How long does a bathroom sink installation take?

Most bathroom sink installations take between two and four hours. If plumbing updates beneath the sink are needed, or if counter or vanity work is part of the project, the timeline extends. Your plumber will give you a clear estimate before the work starts.

What styles of bathroom sinks can you install?

We install every major style including drop-in, under-mount, vessel, pedestal, and wall-mounted sinks. Each style has different plumbing and support requirements, and we walk you through the right choice for your vanity and household.

Do I need to replace the faucet at the same time?

You don’t have to, but it’s often the easiest moment to do it. New supply lines and clean connections go in during the sink install, and adding a new faucet at the same time saves a second visit later.

Can you install a sink where none currently exists?

Yes, though the scope depends on whether supply and drain lines can be reasonably extended to the new location. Our plumber evaluates feasibility during the visit and walks you through what the project would involve.

What should I do if water is pooling in the cabinet below my sink?

That’s a call to make now rather than later. Water in the cabinet means something is leaking, and the damage below gets worse fast. We respond quickly to water issues and can often address the leak and the replacement together.
