We use appropriate diagnostic equipment, cameras, pressure gauges, acoustic leak detectors, to confirm the actual source of the problem before recommending any repair.
You receive a clear, itemized written estimate covering all labor, materials, and permit costs before any repair work is authorized.
Licensed technicians complete repairs using code-compliant materials and methods, obtaining required permits and scheduling inspections as needed.
Repaired systems are pressure-tested, flow-tested, and visually inspected before we consider the job finished.
We remove all debris, protect finished surfaces throughout the job, and restore the work area fully before leaving the property.
We review what was repaired, explain the root cause, and give you straightforward guidance on what to watch for going forward.

Yes. MT Dunn Plumbing maintains around-the-clock emergency availability for Wilsonville residential and commercial customers. When a pipe fails, a sewer line backs up, a water heater floods the utility room, or a gas appliance connection begins leaking, immediate professional response limits the scope of damage and protects occupant safety. Our emergency technicians are dispatched with the diagnostic tools and repair materials necessary to resolve the most common critical plumbing failures on the first visit.
Critical
Immediate Property Damage Risk | Emergency Dispatch Available 24/7
A failed water line inside a wall or ceiling can release hundreds of gallons before the main shutoff is reached. Older Wilsonville homes with galvanized or aging copper pipes face higher rupture risks, especially in winter. Mold can begin developing within 24 to 48 hours.
MT Dunn Plumbing isolates the affected line, replaces the damaged section using code-approved materials, performs a written pressure certification, and documents the repair before restoring service, all in compliance with Oregon Plumbing Specialty Code.
Water staining appearing on a ceiling or wall with no obvious cause, sound of water movement inside a wall when no fixture is running, a sudden unexplained spike in the monthly water bill, or visible wet patches on exterior walls or the foundation perimeter.
Moderate to High Risk
Health Hazard | Same-Day Service Available
Tree roots often invade older Wilsonville sewer lines through cracked joints, especially in aging clay tile or Orangeburg pipes. A blocked sewer can force sewage back into the home, creating serious health hazards and property damage that worsens the longer the line remains clogged.
MT Dunn Plumbing performs video-documented sewer line inspections to confirm the scope of blockage or damage before recommending any repair approach. We use commercial hydro-jetting equipment to restore full pipe capacity and provide a written sewer condition report suitable for insurance carriers and real estate transactions.
Multiple fixtures, toilets, tub drains, floor drains, backing up at the same time; gurgling sounds from the toilet when the washing machine drains; sewage odor near interior floor drains or exterior cleanout caps; soft or unusually green areas of the yard directly above the sewer line path.
Moderate Risk
Hot Water Disruption | Priority Scheduling Available
Tank water heaters over 10 years old are more prone to sediment buildup, corrosion, and anode rod failure, increasing the risk of leaks or tank failure. Wilsonville’s moderately mineralized water speeds sediment accumulation, reducing efficiency and shortening the system’s lifespan without regular maintenance.
MT Dunn Plumbing provides honest, equipment-condition-based guidance on whether repair or replacement is the right decision, rather than defaulting to replacement when a repair is appropriate. All new installations, whether standard tank, tankless, or heat pump water heater, are completed with full permit compliance and Washington County or Clackamas County inspection coordination.
Water at fixtures running warm rather than hot; rust-colored or metallic-tasting hot water; pooling or moisture near the base of the tank; popping or kettling sounds during the heating cycle; the pressure relief valve discharging water repeatedly.
High Risk
Immediate Safety Concern | Emergency Dispatch Available 24/7
Gas leaks at appliance connections or worn flexible gas lines require immediate professional attention. Wilsonville homes with gas ranges, dryers, fireplaces, or water heaters have multiple connection points that should be inspected regularly, especially if original connectors have never been replaced.
If a gas leak is suspected, evacuate the structure, avoid operating any electrical switches, and call 911 and your gas utility before contacting a plumber. MT Dunn Plumbing responds to confirmed and suspected gas line issues around the clock and performs all repairs to Oregon gas code specifications.
Sulfur or rotten egg odor near any gas appliance or along the gas line path; pilot lights that won't stay lit or extinguish unexpectedly; hissing sounds near gas connections; dead vegetation in a line along the gas service route in the yard.
Moderate Risk
Property Damage and Mold Risk | Same-Day Response Available
Wilsonville homes in lower-lying areas often rely on sump pumps to prevent groundwater flooding during wet seasons. A failed sump pump can quickly allow water into crawl spaces or basements, increasing the risk of mold growth, wood rot, and structural damage.
MT Dunn Plumbing diagnoses sump pump failures, replaces failed units with appropriately sized systems, and evaluates the discharge line and check valve to ensure the entire system is functioning as intended before leaving the property.
Sump pump running continuously without cycling off; pump motor running but no water discharging; water staining on crawl space vapor barrier or foundation walls; musty odor in the lower level of the structure; the pump failing to activate when water rises in the pit.

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.
Once per year is the minimum recommended interval for a comprehensive plumbing inspection. An annual evaluation by a licensed Wilsonville plumber identifies corroding pipe sections, sediment-loaded water heaters, sluggish sewer lines, and pressure reducing valves that are no longer maintaining consistent pressure, before any of these conditions produces an emergency.
Regular plumbing maintenance helps Wilsonville homeowners prevent leaks, improve water efficiency, and extend the lifespan of pipes and fixtures. Routine inspections, water heater servicing, drain cleaning, and leak detection reduce the risk of unexpected breakdowns and costly emergency plumbing repairs.
Original Galvanized or Polybutylene Pipe
Older Wilsonville homes may contain galvanized steel or polybutylene water lines prone to corrosion or sudden failure. Professional inspection helps identify risks and plan timely pipe replacement before major leaks occur.
Water Heater Sediment and Anode Rod Condition
Annual water heater flushing removes sediment that reduces efficiency. Regular anode rod inspections help prevent tank corrosion, extend equipment lifespan, and lower the risk of unexpected water heater failure.
Sewer Lateral Condition
Tree roots commonly damage sewer lines in established Wilsonville neighborhoods. A video sewer inspection every two to three years helps detect root intrusion and pipe defects before they cause costly backups.
Pressure Reducing Valve Performance
A properly functioning pressure reducing valve (PRV) protects household plumbing from excessive water pressure. Regular inspection and timely replacement help prevent pipe damage, leaking fixtures, and unnecessary wear on water heaters and appliances.
Crawl Space Moisture and Vapor Barrier Integrity
Wilsonville’s wet climate makes crawl space moisture control essential. Annual inspections of vapor barriers, drainage, and exposed plumbing help prevent water damage, mold growth, and structural issues before they become costly repairs.
Backflow Prevention Device Testing
Oregon requires annual testing of backflow prevention assemblies on irrigation systems and many commercial water services. MT Dunn Plumbing provides certified backflow testing and reporting to maintain regulatory compliance.
We invest in modern plumbing technologies that improve diagnostic accuracy, reduce property disruption, and deliver more reliable long-term solutions for Wilsonville homeowners and businesses.
Articulating sewer cameras inspect interior pipes in real time, identifying root intrusion, corrosion, offsets, and collapse points. We provide recorded video documentation for insurance claims, property sales, and repair verification.
Infrared cameras detect temperature changes behind walls, floors, and ceilings to locate hidden moisture intrusion. This allows precise leak detection without unnecessary demolition of finished surfaces.
Acoustic equipment amplifies underground leak sounds, helping pinpoint pressurized water leaks beneath soil or slabs within inches, minimizing excavation and reducing property disruption.
High-pressure water jets remove grease, scale, and root buildup from pipe interiors, fully restoring flow capacity and improving long-term drainage performance compared to traditional snaking methods.
Cured-in-place pipe lining and pipe bursting techniques repair or replace damaged sewer lines without major excavation, preserving landscaping, driveways, and hardscaped areas.
Energy-efficient heat pump water heaters reduce electricity usage while providing reliable hot water. We install and commission systems according to manufacturer specifications and Oregon code requirements.
Smart shutoff systems detect abnormal continuous flow and automatically stop water supply to prevent major flooding damage. Ideal for travel, rental properties, and water damage prevention.
We provide complete service records including photos, diagnostics, test results, materials used, and permits. This documentation supports insurance claims, resale transactions, and long-term maintenance planning.
Oregon consumer protection standards support your right to a fully itemized written estimate before any work begins. The estimate should specify labor rates, material costs, permit fees, and any anticipated variable costs. No additional charges should appear on the final invoice without your prior written authorization.
Oregon law requires active licensure for all residential and commercial plumbing work. Before authorizing any contractor to begin, verify their Oregon Construction Contractors Board registration, confirm their active plumbing license, and request proof of current general liability and workers’ compensation insurance.
Permitted plumbing work is inspected by the Authority Having Jurisdiction, which means an independent authority verifies that the work was completed correctly. Unpermitted work does not receive that verification, creates liability at property sale, and may void your homeowner’s insurance coverage for related damage claims.
Material selection for plumbing repairs and replacements in Wilsonville requires matching the new material to the existing system, accounting for local water chemistry, and complying with the current edition of the Oregon Plumbing Specialty Code. Because Wilsonville properties span a wide range of construction eras, from 1960s ranch homes to recently completed new construction, our technicians assess each system individually before recommending materials.
PEX-A is our preferred material for whole-house repiping and interior supply line replacements. Its expansion-fit connection method produces leak-resistant joints, its flexibility allows routing through finished walls with fewer fittings, and its freeze tolerance reduces the risk of catastrophic pipe failure during Oregon’s occasional hard freezes.
For exposed plumbing, high-temperature applications, and situations where clients prefer a traditional material with a long performance history, Type L copper remains an excellent choice. We use press-fit and sweat-soldered connections depending on the application and access conditions.
In properties where chemical compatibility with existing CPVC runs is a priority, or where budget constraints favor a cost-effective alternative to copper, CPVC provides reliable corrosion resistance and strong code acceptance in Oregon.
Drain, waste, and vent systems in Wilsonville properties are most commonly completed in Schedule 40 PVC or ABS depending on the application. Both materials provide long service life, broad parts availability, and straightforward compliance with Oregon code requirements for residential and commercial DWV systems.
In multi-unit residential buildings, shared-wall construction, or master bedrooms where drain line noise is a concern, cast iron drain pipe provides substantially better sound attenuation than plastic alternatives. We recommend and install cast iron DWV where noise control is a design priority.
For new construction and whole-house repiping projects, home run manifold systems route individual PEX supply lines from a central manifold to each fixture location, eliminating shared supply branches and providing independent shutoff control for every fixture without affecting the rest of the household.
