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.

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.

Many plumbing leaks begin as minor issues that seem harmless at first. A small drip beneath a sink, moisture around a pipe connection, or a slight drop in water pressure may not appear urgent, but these warning signs often point to larger problems developing behind walls, beneath flooring, or within aging plumbing systems.
Over time, even a slow leak can create significant structural and financial consequences. Water follows the path of least resistance, allowing moisture to spread into insulation, framing, drywall, and subfloor materials before visible signs appear.
Some of the most common consequences of delaying leak repairs include:
Professional plumbing inspections help identify the exact source of the problem and provide repairs designed to prevent recurring leaks and long-term property damage.
Our repair process focuses on accuracy, communication, and long-term reliability. Every project begins with a thorough evaluation to ensure we understand the full scope of the issue before recommending solutions.

Critical
Property Damage Risk | Emergency service available 24/7
A burst pipe can release significant amounts of water within a short period, damaging flooring, drywall, insulation, cabinetry, and structural materials. Older homes with aging plumbing systems may be particularly vulnerable to pipe failures caused by corrosion, pressure fluctuations, or seasonal temperature changes.
MT Dunn Plumbing locates the damaged section, performs targeted repairs, tests system integrity, and restores water service safely.
Sudden water pressure loss throughout the property, water stains appearing on walls or ceilings, pooling water near fixtures, unusual sounds inside plumbing lines, damp flooring, musty odors, wet spots forming in the yard, visible moisture around pipes, unexplained increases in monthly water bills, or corrosion on exposed plumbing components.
Moderate
Health and Property Concern | Same-day appointments available
Sewer line issues can create serious sanitation concerns while disrupting normal plumbing operation. Tree root intrusion, pipe deterioration, grease accumulation, and underground damage are common causes of sewer backups.
MT Dunn Plumbing uses sewer camera inspections, professional drain cleaning equipment, and targeted repair methods to restore proper drainage system performance.
Multiple drains backing up simultaneously, sewage odors inside the property, toilets gurgling during fixture use, recurring drain clogs, standing wastewater around floor drains, wet areas above sewer lines, slow drainage throughout the home, bubbling fixtures, sink backups, or unusual sounds coming from drain systems.
Moderate
Hot Water Loss | Priority scheduling available
Water heater failures can affect daily comfort and household operations. Common causes include sediment buildup, aging components, thermostat failures, and internal corrosion.
MT Dunn Plumbing provides honest repair recommendations and installs replacement systems according to current plumbing requirements and manufacturer specifications.
Complete loss of hot water, inconsistent water temperatures, rust-colored water, moisture beneath the unit, unusual rumbling sounds, leaking connections, reduced hot water supply, pilot light problems, pressure relief valve discharge, or visible corrosion on water heater components.

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.
Most homes should have a professional plumbing inspection at least once each year. Annual evaluations help identify aging components, hidden leaks, water heater issues, pressure concerns, and developing sewer problems before they become emergencies. Older homes and properties with aging plumbing infrastructure may benefit from more frequent inspections.
Regular maintenance is one of the smartest investments property owners can make in plumbing system reliability. Industry data shows that properties following structured maintenance programs experience 50–65% fewer emergency plumbing incidents while reducing annual water waste through leak detection, fixture efficiency improvements, and proactive system servicing.
Aging Water Pipes
Older water pipes should be inspected regularly for corrosion, mineral buildup, hidden leaks, and declining performance. Early identification of pipe deterioration helps prevent unexpected failures, water damage, and expensive plumbing repairs throughout the property.
Drain Line Maintenance
Grease, soap residue, food particles, and debris gradually accumulate inside drain lines over time. Routine cleaning and inspections help maintain proper drainage flow, reduce blockage risks, prevent backups, and support long-term plumbing system reliability.
Water Heater Care
Routine water heater flushing, inspections, and component testing help improve efficiency, and maintain dependable hot water availability. Preventive maintenance also reduces the likelihood of breakdowns, leaks, and unexpected replacement expenses.
Pressure Regulator Evaluation
Water pressure that remains consistently high can place excessive strain on pipes, fixtures, and plumbing connections. Regular pressure regulator evaluations help maintain safe operating levels and reduce unnecessary wear throughout the system.
Main Shutoff Valve Testing
A properly functioning shutoff valve allows homeowners to quickly stop water flow during emergencies. Periodic testing helps ensure reliable operation when needed, reducing potential water damage, minimizing repair costs, and improving emergency preparedness.
Exterior Plumbing Inspection
Outdoor faucets, irrigation connections, exposed piping, and exterior plumbing fixtures should be inspected periodically for leaks, corrosion, and seasonal damage. Routine evaluations help protect plumbing infrastructure and reduce unnecessary water waste.
Advancements in plumbing technology enable repairs and installations to be completed with greater accuracy and efficiency, with less disruption to the property. MT Dunn Plumbing invests in modern diagnostic tools and equipment that help identify problems quickly while supporting long-term solutions.
Specialized cameras travel through drain and sewer lines to provide a real-time view of pipe conditions. This technology helps identify cracks, root intrusion, pipe offsets, and blockages without unnecessary excavation.
Hidden leaks beneath floors, behind walls, and under concrete slabs can be difficult to locate using traditional methods. Electronic leak detection equipment helps pinpoint the exact source while minimizing disruption.
High-pressure water jetting removes grease buildup, mineral deposits, sludge, and invasive roots from drain and sewer lines. This method restores pipe capacity more effectively than many conventional cleaning techniques.
Trenchless repair and replacement methods reduce the need for extensive excavation. Property owners can often preserve landscaping, driveways, patios, and hardscape features while restoring damaged sewer infrastructure.
Modern leak detection and automatic shutoff systems help homeowners identify abnormal water usage and stop leaks before significant damage occurs.
Many Beaverton homeowners are transitioning to tankless water systems because they provide hot water on demand and improve energy efficiency.
Advanced filtration and conditioning systems improve water quality throughout the property while helping protect plumbing fixtures and appliances.
Customers receive detailed documentation, including photographs, inspection findings, and recommendations that can be useful for maintenance planning, insurance claims, and future property improvements.
Customers should receive detailed information regarding labor, materials, and project scope before work begins. This helps eliminate confusion and supports informed decisions.
Qualified plumbers maintain active licensing and insurance coverage to protect both the contractor and property owner.
Professional plumbers take reasonable measures to protect floors, walls, landscaping, and surrounding work areas during service visits.
We help property owners select plumbing materials based on system age, water usage demands, project objectives, and long-term durability expectations. Because many Beaverton properties contain combinations of copper, galvanized steel, ABS, PVC, and cast iron piping, choosing compatible materials is important for reliable performance, corrosion prevention, and future plumbing upgrades.
We frequently recommend PEX for interior water distribution systems because of its flexibility, freeze resistance, and ability to simplify installations in confined spaces.
We install copper piping for exposed plumbing systems and high-temperature water supply applications where strength, longevity, and dependable performance are important.
For many residential water supply projects, we recommend CPVC because of its corrosion resistance, durability, and compatibility with local water conditions.
We install Schedule 40 ABS and PVC piping for drain, waste, and vent systems to provide reliable operation and extended service life.
When durability, sound reduction, and long-term performance are priorities, we may recommend cast iron drain piping for residential applications.
We ensure all materials meet Oregon Plumbing Specialty Code requirements for permitting, inspections, and warranty protection. During remodels, additions, and plumbing upgrades, we also recommend proper pipe sizing to support future fixture installations without requiring extensive system modifications.
Turn off the main water supply immediately if possible and contact a licensed emergency plumber. Quick action can significantly reduce water damage.
Traditional tank water heaters generally last between 8 and 12 years, while properly maintained tankless systems often provide a longer service life.
Many homeowners find value in the energy efficiency, space savings, and continuous hot water supply provided by tankless systems.
Properties with mature landscaping, older sewer systems, or recurring drainage issues often benefit from periodic camera inspections.
Yes. Even minor leaks can create hidden moisture problems that affect structural materials and contribute to mold growth over time.
