EXCELLENT Based on 95 reviews Posted on Google RubenTrustindex verifies that the original source of the review is Google. Late Sunday night we had an emergency leak, where we were forced to shut off water to entire house. I reach out MT Dunn plumbing and in a short notice and within 35 mins Irich was able to come over and fixed our leak. Truly appreciate the quick response especially being late Sunday night around 9-10pm!!!Posted on Google Matt CorradoTrustindex verifies that the original source of the review is Google. We inadvertently discovered our kitchen and washing machine drains were disconnected and dumping water underneath the house, in the crawlspace. We may never know why or for how long but Irich responded to my call personally and set a date within a single business day knowing we'd couldn't use the kitchen until it was fixed. He was here on time and had it repaired in a half day. Proper invoicing and estimates based on labor and parts always makes me happy. So glad to have a plumber now. I won't go anywhere else.Posted on Google Nick A.Trustindex verifies that the original source of the review is Google. I have used MT Dunn many times, mostly smaller projects.

This is the 3rd time we've used M T Dunn Plumbing, and the 3rd time we've have a 5-star experience. I would recommend them to everyone!Posted on Google Rie JacobsTrustindex verifies that the original source of the review is Google. Irich is very easy to work with and always shows up on time. He’s honest, professional, and very efficient. His work is fast but never rushed. He does things the right way and never cuts corners. Over the past three years, he has helped us three times: installing a water heater, replacing some toilet parts, and installing a new toilet. Every job was done quickly and professionally. He’s also very respectful of our home and keeps things clean while working. On top of that, he’s a genuinely kind person—even great with our dog 🐶 His pricing is fair and he never overcharges. It’s hard to find someone this trustworthy. I highly recommend him. Thank you Irich!Posted on Google Brian SecrestTrustindex verifies that the original source of the review is Google. I've had MT Dunn plumbing handle a couple of plumbing issues we've had over the last few years. Our most recent visit was due to a leaking valve going to our guest bathroom toilet. It was stripped and Irich was able to fix it in short order. Friendly, transparent, punctual, and knowledgeable. We highly recommend Dunn plumbing and Mikes son Irich.Posted on Google Cooper HowardTrustindex verifies that the original source of the review is Google. This is the second time I’ve used M T Dunn Plumbing and both experiences have been great. I recently discovered I had a leaky pipe underneath my cement driveway. M T Dunn came out and assessed the situation and gave me multiple ways get it fixed with varying costs. I decided what I wanted to do and they came out a few days later and took care of it. They cut a hole in the cement, found the leak, fixed it and patched the driveway in a single day which will end up saving me a ton of money. They’re very fair and have gotten things done quickly and easily both times I’ve needed them.Posted on Google philip salvadorTrustindex verifies that the original source of the review is Google. Very upfront on pricing, finished the work as expected.Posted on Google Daniel CruzTrustindex verifies that the original source of the review is Google. Irich is great and excellent work and did same day service..I would highly recommend mt plumbing for anyone

When your sink isn’t working right, MT Dunn Plumbing gets it fixed properly, without unnecessary parts or repeat visits.
A methodical process helps us catch the actual cause, whether it’s the faucet, the drain, or something underneath.
Technicians ask about symptoms, whether it’s dripping, slow drainage, low water pressure, or a bad smell, to focus the inspection efficiently.
The faucet body, handles, and spout are checked for drips, wobble, or difficulty turning, which often point to worn internal parts.
Shutoff valves and supply lines beneath the sink are examined for corrosion, loose fittings, or slow leaks at the connection points.
Technicians run the faucet to check for reduced flow, which can indicate a clogged aerator, mineral buildup, or a valve issue.
The drain, P-trap, and stopper mechanism are checked for clogs, corrosion, or loose slip joints that could be causing leaks or slow draining.
If present, the disposal unit is tested for jamming, leaking, unusual noise, or complete failure to power on.
The basin itself is inspected for cracks, chips, or loosening from the countertop, especially in drop-in or undermount installations.
Once inspection is complete, technicians pinpoint the specific failed component, whether it’s a cartridge, O-ring, trap seal, or disposal motor.
Worn parts are replaced, connections are tightened or resealed, and clogs are cleared using appropriate tools for the situation.
The faucet, drain, and disposal (if applicable) are run through a full cycle to confirm the repair holds under normal use.
Technicians clean the work area and walk you through what was repaired and any maintenance tips specific to your fixtures.
Most sink repairs are completed within thirty to ninety minutes, depending on the number of issues and parts availability.
Small sink issues rarely stay small for long. Call us if you notice:

From what we’ve seen, the answer is absolutely yes. At MT Dunn Plumbing, we’ve seen how even a small dripping sink can quietly waste thousands of gallons of water over time and lead to higher utility bills. What seems like a minor annoyance today can become an expensive habit if it’s left unresolved.
Many homeowners assume a slow drip isn’t worth worrying about because the amount of water seems insignificant. In reality, those steady drips add up every hour of every day. Over weeks and months, that wasted water can noticeably increase your monthly water bill, especially when multiple fixtures in the home have small leaks.
We’ve visited homes where customers were surprised by unexpectedly high water bills, only to discover that a dripping faucet had been running continuously for months. In many cases, the issue was something simple, like a worn washer, damaged cartridge, loose connection, or aging faucet component. Addressing the problem early would have cost far less than paying for months of wasted water.
We also remind homeowners that a drip is often a symptom rather than the actual problem. Excessive water pressure, deteriorating seals, corrosion, or internal faucet damage may all contribute to the leak. Identifying the real cause helps prevent the issue from returning and protects the rest of your plumbing system.
If your sink is dripping, don’t wait for the problem to grow. A timely repair can reduce unnecessary water waste, help keep your utility bills under control, extend the life of your plumbing fixtures, and give you confidence that a small leak won’t turn into a much larger expense later.
At MT Dunn Plumbing, we repair a wide variety of residential and light commercial sinks. Whether the issue is a leak, clog, damaged fixture, or poor drainage, our technicians diagnose the problem and provide the appropriate repair.
