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.

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.

Critical
Property Damage Hazard | Emergency response available 24/7

Sudden drop in water pressure, water stains forming on ceilings or walls, sounds of flowing water behind surfaces, unexplained increases in water bills, wet flooring, standing water near plumbing fixtures, saturated areas in the yard, musty odors indoors, visible moisture around plumbing connections, or corrosion on exposed pipes.
Moderate
Health and Safety Concern | Same-day appointments available
Sewer backups create sanitation risks and can disrupt multiple plumbing fixtures throughout a property. Common causes include root intrusion, collapsed pipes, grease accumulation, and aging sewer infrastructure.
MT Dunn Plumbing performs video inspections, drain cleaning services, and sewer repairs designed to restore proper wastewater flow.
Multiple drains backing up together, sewer odors inside the home, gurgling toilets during use, slow draining fixtures, wastewater near floor drains, soggy areas above sewer lines, recurring drain issues, bubbling drains, sink backups, or unusual drainage sounds throughout the plumbing system.
Moderate
Hot Water Disruption | Priority scheduling available
A failed water heater can affect daily activities and comfort. Sediment buildup, worn components, and aging equipment often contribute to breakdowns.
MT Dunn Plumbing evaluates equipment condition, provides repair recommendations, and installs replacement units according to applicable plumbing requirements.
Lack of hot water, fluctuating temperatures, rusty water, water collecting beneath the tank, unusual operating noises, leaking fittings, insufficient hot water supply, ignition issues, pressure valve discharge, or visible signs of corrosion on equipment surfaces.
High Priority
Water Supply Risk | Emergency service available
Many properties in and around Gaston depend on private water systems. Problems involving pressure tanks, pumps, or water supply components can affect the entire property.
MT Dunn Plumbing diagnoses pressure system problems, repairs damaged components, and restores reliable water delivery throughout the property.
Loss of water service, fluctuating water pressure, unusual pump cycling, reduced fixture flow, air in water lines, pressure tank issues, inconsistent water delivery, pump noises, water discoloration, or higher-than-normal energy consumption.

MT Dunn Plumbing provides reliable plumbing services with transparent pricing. We deliver high-quality repairs and installations, ensuring your plumbing problems are resolved efficiently and affordably.
Annual plumbing inspections are recommended for most properties. Routine evaluations help identify hidden leaks, aging pipes, water heater concerns, and drainage issues before they become costly emergencies. Rural properties and older homes often benefit from more frequent inspections.
Regular maintenance is one of the most cost-effective ways to improve plumbing reliability. Industry studies show that properties enrolled in routine maintenance programs experience significantly fewer emergency plumbing failures while reducing water waste through early leak detection, fixture optimization, and proactive equipment servicing.
Aging Plumbing Systems
Older plumbing systems should be inspected regularly for corrosion, weakened pipe walls, hidden leaks, mineral buildup, and joint deterioration. Early detection helps prevent unexpected pipe failures, water damage, costly emergency repairs, and disruptions to normal household plumbing performance.
Drain System Care
Periodic drain maintenance helps remove grease, soap residue, mineral deposits, and accumulated debris before serious blockages develop. Routine cleaning supports consistent drainage performance, reduces the likelihood of backups, and helps extend the lifespan of drain lines.
Water Heater Maintenance
Routine water heater flushing, component inspections, and performance evaluations help reduce sediment accumulation, improve heating efficiency, and extend equipment lifespan. Preventive maintenance also lowers the risk of unexpected breakdowns, water damage, and hot water interruptions.
Water Pressure Monitoring
Consistent water pressure helps protect plumbing fixtures, household appliances, water heaters, and pipe connections from unnecessary strain. Monitoring pressure levels regularly can identify developing system issues early and help prevent costly plumbing component failures.
Emergency Shutoff Testing
Functional shutoff valves allow property owners to quickly stop water flow during plumbing emergencies. Routine testing helps ensure valves operate properly when needed, reducing potential water damage, limiting repair costs, and improving overall emergency preparedness.
Exterior Plumbing Components
Outdoor plumbing fixtures, hose bibs, and irrigation connections should be inspected regularly for leaks, corrosion, weather-related wear, and freeze damage. Preventive maintenance helps protect exterior plumbing systems and reduce unnecessary water loss.
Modern plumbing technology allows problems to be identified faster and repaired more efficiently than ever before. At MT Dunn Plumbing, we use professional equipment and proven techniques that help minimize disruption while improving long-term plumbing performance.
Rather than relying on guesswork, sewer cameras provide a clear view inside drain and sewer lines. This allows our plumbers to identify root intrusion, pipe collapses, grease buildup, and hidden damage with greater accuracy.
Leaks hidden behind walls, beneath foundations, and underground can be difficult to locate. Electronic leak detection equipment helps pinpoint the source while reducing unnecessary demolition or excavation.
Hydro jetting uses high-pressure water to clear stubborn blockages, grease buildup, sediment accumulation, and invasive tree roots. This process helps restore proper flow throughout drain and sewer systems.
Traditional sewer replacement often requires extensive digging. Trenchless repair methods allow many underground pipe problems to be addressed while preserving landscaping, driveways, and outdoor features.
Modern leak detection technology can monitor water usage and identify abnormal flow patterns before major property damage occurs.
New tankless and energy-efficient water heaters provide reliable hot water while helping reduce utility costs and improve overall performance.
Filtration and conditioning systems improve water quality throughout the property while helping extend the lifespan of plumbing fixtures and appliances.
Inspection reports, photographs, videos, and repair documentation provide valuable records for future maintenance planning, insurance requirements, and property transactions.
Customers should receive a written explanation of the work being performed, including labor, materials, and project scope before repairs begin.
Qualified plumbing work should be completed by properly licensed professionals who understand local codes and industry requirements.
Property owners deserve straightforward answers regarding repair options, expected timelines, and potential costs.
We help property owners choose plumbing materials based on existing infrastructure, water quality characteristics, project requirements, and long-term system reliability goals. Because many Gaston properties include a mixture of older galvanized piping, copper lines, and cast iron drains, selecting appropriate materials helps improve compatibility, reduce corrosion concerns, and support future plumbing improvements.
We commonly recommend PEX for interior water supply installations because it offers flexibility, freeze resistance, and efficient routing through challenging spaces.
We use copper piping for exposed plumbing systems and hot water applications where durability, reliability, and long service life remain priorities.
For many residential plumbing projects, we recommend CPVC due to its resistance to corrosion, dependable performance, and compatibility with local water conditions.
We install Schedule 40 ABS and PVC piping for drain, waste, and vent systems, delivering dependable performance and long-term reliability.
When noise control, strength, and service longevity are important, we may recommend cast iron drain piping for residential properties.
We ensure all materials comply with Oregon Plumbing Specialty Code requirements for inspections, permits, and warranty protection. When planning remodels, additions, or plumbing improvements, we also recommend pipe sizing that supports future fixture expansion without requiring major system redesigns.
