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.

Critical
Property Damage Risk | Emergency Service Available 24/7
A burst supply pipe can discharge significant volumes of water rapidly, causing damage to framing materials, flooring systems, insulation, drywall, and finished interior surfaces. Aging copper and galvanized piping commonly found in older Tigard properties may be especially vulnerable. Mold development can begin within 24–48 hours after a significant flooding event.
MT Dunn Plumbing shuts down affected supply lines, completes targeted repairs, and provides pressure verification documentation before restoring service while maintaining compliance with Oregon plumbing requirements.
Sudden reduction in water pressure, discoloration on ceilings or walls, sounds of moving water behind surfaces, unusual increases in water bills, or damp areas forming away from plumbing fixtures.
Moderate
Health & Property Risk | Same-day appointments available
Sewer backups expose occupants to potential health hazards while also creating the risk of substantial property damage. Older sewer systems may experience root intrusion, deteriorating joints, pipe collapse, and drainage restrictions that disrupt normal wastewater movement.
MT Dunn Plumbing performs video sewer inspections before recommending solutions, uses professional hydro-jetting equipment to restore flow when necessary, and provides written sewer assessments that support insurance claims and property documentation.
Multiple drains backing up simultaneously, sewer odors inside the building or near exterior cleanouts, toilet gurgling during fixture use, or wet and sunken areas developing above underground sewer routes.
Moderate
System Risk | Priority scheduling for hot water restoration
Failed heating elements, deteriorated tanks, worn pressure relief valves, damaged anode rods, and aging plumbing connections are among the most frequent causes of water heater breakdowns. A professional assessment helps determine whether repairs remain practical or if replacement is the better investment.
MT Dunn Plumbing offers honest repair and replacement guidance based on actual system condition. Replacement installations, including traditional, tankless, and hybrid models, are completed according to applicable permit and inspection requirements.
No hot water available, rust-colored water at fixtures, moisture collecting around the tank, unusual rumbling noises during heating cycles, or a continuously leaking pressure relief valve.
High Risk
Operational & Compliance Hazard | Emergency commercial dispatch available
Commercial plumbing problems can affect daily operations, occupant safety, and regulatory compliance obligations. Restaurants, medical facilities, retail centers, office buildings, and multi-unit properties often require rapid response from professionals equipped to handle larger and more complex plumbing systems.
MT Dunn Plumbing offers emergency commercial service during evenings and weekends to reduce operational disruption while providing repair records and system documentation when required by property owners, insurers, or governing agencies.
Several restrooms malfunctioning simultaneously, grease trap overflow, reduced hot water availability, ceiling damage near supply piping, or plumbing concerns identified during compliance inspections.
Moderate
System Risk | Same-day service available
When low water pressure and water discoloration appear together, they frequently indicate aging supply piping or a deteriorating water service connection instead of a simple fixture issue. Internal pipe corrosion can restrict water movement while releasing sediment and metal particles that contribute to fixture wear and reduced plumbing system efficiency.
MT Dunn Plumbing conducts comprehensive water system testing, from service line pressure evaluation to fixture performance verification, and provides a detailed report with findings and recommendations upon completion.
Rusty or cloudy water from multiple fixtures, decreased water pressure throughout the property, mineral deposits on faucets and showerheads, or visible corrosion around exposed water lines.

At minimum, once per year. A professional plumbing inspection performed by a licensed Tigard plumber can identify deteriorating pipes, aging water heaters, restricted sewer lines, and failing shutoff valves before major problems occur. Homes with older galvanized plumbing, cast iron drain systems, or properties built before 1980 generally benefit from additional inspections and preventative maintenance services.
Preventative maintenance remains one of the smartest investments in long-term plumbing performance. Industry studies show that properties following scheduled maintenance programs experience fewer emergency repairs while lowering annual water costs through leak prevention and improved plumbing efficiency.
Aging Pipes
Older Tigard homes frequently contain original galvanized steel water piping and cast iron drainage systems nearing the end of their service life. Scheduled evaluations help prevent sudden plumbing failures.
Drain Buildup
Mineral deposits, grease accumulation, soap residue, and debris can gradually restrict drainage. Regular cleaning and video inspections help identify problems early.
Aging Water Heaters
Conventional water heaters generally last between 8 and 12 years. Routine flushing, inspections, and replacement planning help avoid sudden hot water interruptions.
Pressure Reducing Valves
Pressure regulator failure can cause inconsistent water pressure that accelerates fixture wear and stresses plumbing connections. Annual inspections support stable system performance.
Seized Shutoff Valves
Non-functioning shutoff valves can worsen plumbing emergencies by delaying water isolation. Regular valve testing helps ensure reliable operation when needed.
Gas Appliance Venting
Yearly inspections of gas appliance venting systems help protect indoor air quality while supporting safe and efficient equipment operation.
We implement modern plumbing technologies that improve operational efficiency, increase diagnostic accuracy, minimize property disruption, and provide lasting value for homeowners and businesses throughout Tigard, OR.
High-definition camera systems inspect drain and sewer lines to identify obstructions, pipe defects, root intrusion, connection failures, and structural damage without destructive excavation. We use this technology to support accurate diagnostics, repair recommendations, and property documentation.
Sensitive leak detection equipment identifies concealed leaks beneath slabs, inside walls, and within underground piping systems by locating the sound of escaping water. This allows accurate diagnosis while reducing unnecessary demolition and surface disruption.
High-pressure water cleaning technology removes grease, scale buildup, roots, and accumulated debris that traditional cleaning methods cannot fully eliminate. We use hydro-jetting to restore optimal flow and improve long-term drainage performance.
Monitoring systems installed near plumbing fixtures and equipment continuously track moisture levels and provide instant alerts when leaks occur. We recommend these devices to help property owners prevent costly water damage.
Advanced trenchless repair and replacement methods restore damaged sewer lines without extensive excavation through landscaping, sidewalks, or paved surfaces. These technologies help lower restoration costs and reduce disruption during repairs.
Energy-efficient tankless systems provide hot water on demand while eliminating standby heat loss associated with traditional storage tanks. We install these systems to improve performance and maximize energy savings.
Installed at the property’s main water entry point, filtration systems reduce contaminants, sediment, and chlorine from incoming water. We use these solutions to improve water quality and protect plumbing components.
Comprehensive inspection records include video evidence, pressure testing results, photographs, and system mapping information. We provide this documentation to support maintenance planning, insurance requirements, and real estate transactions.
Property owners are entitled to a comprehensive written estimate covering labor, materials, permit expenses, and all service-related costs before work begins. No unexpected charges should appear on the final bill without prior authorization and customer approval.
Only individuals with active Oregon plumbing licenses may legally complete residential and commercial plumbing work. Property owners should confirm licensing status, insurance protection, and compliance with relevant safety regulations and local code requirements before proceeding.
Qualified plumbers should take appropriate measures to protect customer property throughout every project. Floors, walls, cabinets, fixtures, and nearby surfaces should remain protected to minimize the risk of accidental damage during plumbing services.
We assist property owners with selecting plumbing materials based on system age, water conditions, project requirements, and long-term performance goals. Because many Tigard properties contain a mix of older and newer piping materials, choosing compatible components helps minimize corrosion concerns, improve system reliability, and support future plumbing upgrades.
PEX is commonly recommended for interior water supply systems because it offers flexibility, freeze resistance, and efficient installation in challenging spaces.
We often use copper piping for exposed plumbing applications and hot water distribution systems where strength and longevity are important.
CPVC remains a practical option for many water supply systems because of its corrosion resistance and compatibility with local water conditions.
Schedule 40 ABS and PVC piping are widely used for drain, waste, and vent applications because they provide dependable long-term performance.
Where durability and quieter drainage operation are important, cast iron drain piping may be recommended for residential plumbing systems.
We verify that all materials comply with Oregon Plumbing Specialty Code requirements to support permit approval and warranty protection. During remodeling projects, bathroom renovations, and accessory dwelling unit additions, we also recommend appropriate pipe sizing that allows future fixture additions without extensive system redesign.
Response times vary based on demand and location, but our emergency plumbers prioritize urgent situations and work to respond as quickly as possible.
Yes, preventative maintenance often identifies small issues before they become major repairs, helping reduce long-term expenses.
Yes, we provide sewer inspections, repairs, trenchless solutions, and complete sewer line replacements.
