Our 24/7 emergency team is available day and night, ready to respond to calls across Hillsboro, from the neighborhoods around Reedville Creek to homes near Shute Park.

Expertise in Residential Sewer Systems
Plumbing systems in Hillsboro vary widely depending on the home’s age and neighborhood. MTDunn Plumbing has worked on everything from older clay sewer lines to modern PVC installations, giving us the expertise to handle any situation.
We understand how shifting soil conditions, seasonal rainfalls, and tree root intrusions often lead to sewer gas problems in Hillsboro homes. That’s why our team provides professional sewer gas detection, plumbing repair, and odor removal services designed to keep your home safe and comfortable.
Homes in rural Hillsboro that use septic systems and those in Tanasbourne connected to city sewers can all face sewer gas issues. Our licensed team has the expertise to diagnose and fix problems correctly. We repair broken traps, reseal toilets, unclog vents, and replace deteriorated piping to keep your system working properly.
Advanced Diagnostic and Repair Tools
Our process begins with a thorough inspection. We use smoke testing, video camera inspections, and pressure testing to identify hidden leaks or blocked vents. These advanced tools allow us to find the precise location of the problem, minimizing unnecessary digging or demolition.
Once the issue is identified, we repair or replace the faulty components, whether it’s a dried‑out trap, a cracked pipe, or a malfunctioning vent stack. Our goal is to provide solutions that not only eliminate current odors but also prevent future issues.
COMMON SEWER GAS PROBLEMS IN HILLSBORO HOMES
Persistent Odors in Bathrooms or Kitchens
A common complaint from Hillsboro homeowners is a sewer smell near sinks, tubs, or floor drains. This often occurs when water evaporates from P-traps, leaving an open pathway for gases to enter your home. In older Hillsboro homes, corroded pipes, worn gaskets, or loose connections may worsen the issue over time.
Our technicians at MTDunn Plumbing inspect, refill, and check traps for leaks or cracks. We also verify that venting systems are working properly, ensuring that gases exit through the roof rather than into living spaces.
Sewer Gas Smell in Basements and Crawl Spaces
Basements and crawl spaces are particularly vulnerable to sewer gas infiltration. Hillsboro’s frequent rains and high groundwater levels can stress underground pipes, causing small leaks that release odors. In homes with sump pumps or floor drains, dried‑out traps are another common culprit.
MT Dunn Plumbing inspects underground lines using video cameras, repairs cracks or separations, and restores trap seals. By addressing both the plumbing system and the environmental conditions, we ensure odors are eliminated at the source.
Odors After Heavy Rain or Storms
Hillsboro’s rainy climate often highlights sewer system weaknesses. After a storm, you may notice odors caused by overloaded sewer lines, backflow, or blocked vents. Tree roots seeking water during rainy seasons can also infiltrate sewer pipes, leading to hidden leaks.
MTDunn Plumbing specializes in storm‑related sewer gas issues. We clear blockages, repair infiltration damage, and install backflow prevention devices to protect your home from recurring problems.
Seasonal and Long-Term Issues
In addition to day-to-day odors, some homeowners experience seasonal problems linked to changes in temperature and humidity. Dry summer weather can cause traps to evaporate faster, while cold winters may stress old vent pipes and seals. Left unaddressed, these issues often resurface year after year.
Our team at MTDunn Plumbing provides proactive maintenance and customized repair solutions that consider for Hillsboro’s climate and soil conditions. By combining inspections, vent cleaning, and system upgrades, we ensure your plumbing remains reliable in every season.
PROFESSIONAL SOLUTIONS FOR SEWER GAS ODORS
Trap and Seal Repairs
Traps and seals are the frontline defense against sewer gas entering your home. When they dry out, crack, or loosen, odors quickly find their way inside.
At MTDunn Plumbing, we repair or replace defective traps, reseal loose toilets, and install proper floor drain covers to keep gases contained. Even small adjustments, like making sure unused drains are filled with water or installing trap primers, can prevent recurring odors before they become major issues.
For older Hillsboro homes, we often recommend upgraded trap systems that better withstand daily use, ensuring long-term protection against unpleasant smells.
Pipe and Vent Replacement
Cracked pipes, deteriorating joints, or blocked vents are some of the most common culprits behind sewer gas leaks. Over time, these problems not only create foul odors but can also weaken your plumbing system.
MTDunn Plumbing uses advanced diagnostic tools such as smoke testing and video inspections to locate hidden damage quickly and accurately. Once identified, we replace problem sections with durable, modern materials designed to last for decades. For venting issues, we clear debris, remove obstructions caused by pests or tree debris, and ensure every stack vents properly above the roofline for safe air circulation.
Odor Prevention Maintenance
Beyond repairs, MTDunn Plumbing helps Hillsboro homeowners prevent future problems before they start. Our team provides scheduled inspections, trap maintenance, and thorough vent cleaning to keep your plumbing system operating safely year-round. We also educate homeowners on simple steps, such as occasionally running water through little-used drains, that help keep traps filled.
For properties outside city sewer lines, we provide clear guidance on septic tank pumping schedules to avoid costly backups. By focusing on prevention as well as repair, we give homeowners peace of mind and protect both property value and indoor air quality.
Comprehensive System Upgrades
Sometimes sewer gas issues are the result of an aging plumbing system that needs more than simple repairs. In these cases, MTDunn Plumbing offers full-system upgrades designed for the unique needs of your home. This may include replacing outdated cast iron pipes with PVC, upgrading venting systems to current building codes, or installing backflow prevention devices for added protection.
We also recommend eco-friendly solutions when possible, giving homeowners reliable performance while reducing environmental impact. These comprehensive upgrades not only solve immediate odor problems but also ensure your plumbing system is prepared for decades of safe, efficient use.

Health and Air Quality Concerns from Sewer Gas
Sewer gas is not just an unpleasant smell, it directly impacts your indoor air quality. The mixture of methane, ammonia, and hydrogen sulfide can cause headaches, fatigue, nausea, and breathing difficulties when exposure continues over time. In higher concentrations, these gases may even become flammable, creating serious safety risks.
Many Hillsboro homeowners first notice sewer gas odors in closed spaces like bathrooms, basements, or laundry rooms where air circulation is limited. That’s why professional response isn’t just about comfort, it’s about protecting your family’s health. At MTDunn Plumbing, we prioritize fast detection and removal to restore a safe living environment before the problem escalates.

MAINTENANCE TIPS FOR HILLSBORO HOMEOWNERS
Keeping up with small maintenance habits goes a long way in protecting your home from sewer gas problems. Follow these proven tips:
- Pour water into seldom-used drains monthly to keep trap seals intact and prevent gases from entering your home.
- Test sump pumps before heavy rains to ensure they can handle Hillsboro’s wet climate and protect basements from odor issues.
- Check toilets for movement or loose seals since even minor gaps can release sewer gas into living spaces.
- Keep roof vent stacks clear of debris like leaves or nests so gases are properly vented outdoors.
- Schedule plumbing inspections for older homes to detect cracked pipes, corroded lines, or hidden leaks early.
- Consider preventative root-control treatments if large trees grow near your sewer line to avoid blockages and pipe damage.
Seasonal Maintenance Tips for Hillsboro Homes
Each season brings different challenges to local plumbing systems:
- Summer: Traps dry out faster in unused drains, allowing odors to escape. Running water monthly prevents this.
- Winter: Freezing temperatures can affect vent stacks, restricting airflow and trapping gases indoors. Insulation and vent checks help.
- Rainy Season: Heavy storms raise groundwater levels and add pressure to underground pipes, making cracks and root intrusions more likely. Preventive drain clearing and pipe inspections reduce the risk.
By combining seasonal awareness with professional inspections, MTDunn Plumbing helps Hillsboro homeowners maintain safe, odor-free homes year-round.
How Much Does It Cost to Fix a Sewer Gas Smell in Hillsboro?
The cost of fixing a sewer gas smell in Hillsboro varies depending on the source of the problem and the scope of repairs needed. For minor issues, such as refilling a dry trap or resealing a loose toilet, the cost may be on the lower end, around $1,000. If the problem involves a blocked vent stack, corroded pipes, or damaged seals that require replacement, homeowners can expect costs closer to $2,000.
In more complex cases such as repairing underground sewer lines, replacing cracked pipes, or performing extensive diagnostic camera inspections the price can increase beyond that range. The overall cost is also influenced by the age of your plumbing system, the location of the issue, and how quickly it is addressed.
At MTDunn Plumbing, we provide upfront pricing, detailed assessments, and cost-effective repair strategies designed to restore comfort and safety to your home. By catching issues early, many homeowners avoid expensive emergency repairs and enjoy long-term peace of mind.
Why Are Preventive Sewer System Inspections Important for Hillsboro Homes?
While emergency repairs fix immediate issues, preventive inspections are the foundation of long-term plumbing health. Sewer systems in Hillsboro often face stress from shifting soils, heavy seasonal rains, and intrusive tree roots. Regular inspections help detect small cracks, worn seals, or partial blockages before they escalate into foul odors or major leaks.
Our plumbers recommend video camera inspections and vent testing every few years, especially in older homes with original clay or cast-iron pipes. By identifying early signs of deterioration, homeowners can avoid expensive emergencies and extend the lifespan of their plumbing system.
FREQUENTLY ASKED QUESTIONS
What are the health risks of sewer gas in my home?
Sewer gas contains methane and hydrogen sulfide, which can cause headaches, nausea, dizziness, and long‑term respiratory problems. High concentrations may even be flammable. Prompt professional attention is essential.
Can I handle sewer gas problems on my own?
Yes, homeowners can sometimes refill a dried trap or clear a minor clog, but no, deeper issues like cracked pipes, blocked vents, or faulty seals should be left to professionals.
Do sewer odors often appear after heavy rain?
Yes, rain can overwhelm sewer systems or cause groundwater to infiltrate pipes, forcing gases indoors. Blocked vents and tree root intrusions can also make odors worse during storms.
Does it take long to repair sewer gas problems?
No, most small jobs, such as resealing a toilet or clearing a vent, take just one to three hours. Larger repairs like pipe replacements may require a full day or more.
Should I replace pipes instead of repairing them?
Yes, if your home has aging clay or cast-iron pipes, recurring leaks, or major cracks, replacement is often the best long-term solution. Modern PVC and ABS pipes are more durable and resistant to Hillsboro’s soil conditions.
How Does MT Dunn Plumbing Detects Hidden Sewer Gas Leaks?
Our team uses smoke testing, video camera inspections, and pressure testing to pinpoint the source of sewer gas. These advanced diagnostic tools help identify cracks, blocked vents, or failing seals without unnecessary digging or demolition.
Can cold weather in Hillsboro make sewer gas odors worse?
Yes. In winter, frozen vents or reduced air circulation can trap gases inside your home. Proper venting and insulation help prevent seasonal odor issues.
