"Excellent! Marty and his partner definitely know septic systems and how to evaluate their functioning level. We were very pleased and impressed with their knowledge, work ethic and the time they spent carefully checking every part of our system and explaining what they found to us. I will definitely use them again and tell neighbors as well. Several folks in my neighborhood tried going with the lowest bids on septic issues and all three had major repercussions! It pays to hire high quality people."

"Our existing septic tank was only a few years old, but the associated drainfield was failing and required replacement. Due to a small lot, our options were limited; but rather than a huge and unsightly bottomless sand filter, we opted for a less obtrusive (but expensive) treatment unit and pumps along with the needed replaced drainfield. Cory was very helpful in explaining complex options and costs."

"My experience was absolutely STELLAR! I had a slow draining sink and toilet. Called around 7:45am, dispatch called me back about an hour late to state someone would be out 10am or later... about 9:55am, Josh(I think that was his name?) and Allison were at my door and got to work. They outlined the steps they were going to take, provided me with options on how to proceed, and then after my acceptance, got to work. 3-hours and at a out-of-pocket cost of $236, both my toilet and sink drain are working perfectly. And as part of that time, they had someone with a camera inspect the sewer line to ensure there wasn't a larger underlying issue (there wasn't). I can't speak to the installation aspects of their business, nor can I speak to issues that aren't ultimately cleared-up with a powered snake and auger, but for me, it was absolute perfection! If I ever have another plumbing issue, this will definitely be the FIRST company I contact."

"The men at Ralston Excavating Inc. Wasted no time finding the cause of my overflowing septic tank (a crushed drain line) and replacing the line with new pipe. The service they provided was swift, professional and cost effective. I am very pleased with their work and highly recommend them to anyone needing help repairing or replacing a septic system."

"I had a clogged drain line near the street that a rooter guy couldn't break through. I thought I was looking at having to replace the entire line. At the risk of throwing good money after bad, I called Grumpy's. I got great advice over the phone including a number to call if I decided to have the line dug up. The rate I was quoted was reasonable. Grumpy came out and cleared the line in less than half an hour. In addition, he put a scope down the line, found the exact location where roots were getting through, and marked the spot with paint at no extra charge. He wrote down the coupling and pipe I would need to make the repair. When I dug, the break was right where he indicated. Grumpy was a real pro. He saved me a bunch of time and money."

"The job was well executed. Compliments to everyone at Speedy Septic. Hayden Buley was very quick to respond to my request for an estimate. I called several other septic system installers on listed on Angie's list who were either booked far into the future, or who did not respond to messages. Hayden made an appointment and came out to inspect the site as agreed and on time. He was very personable and professional. He set up a second meeting involving Mr. Rooter. He then provided an emailed cost estimate. One uncertainty in cost was whether the drain field needed to be replaced. This could not be determined until it was unearthed and inspected. Fortunately the drain field was still functioning well. A new distribution box was needed, and the drain field pipes were cleaned with the "Jetter" and all was well. The job took a little longer than planned due to bad weather. Our only winter snow and ice storms happened while the job was underway. We live on a fairly high hill and the snow and ice conditions were fairly bad, so I can't fault Speedy Septic for having the job take a little bit longer than planned. Then made sure that we had functioning toilets throughout most of the job, always when their work day was done. I'm happy to report that original cost estimate was very accurate. Compliments to all of the Speedy Septic and Mr. Rooter crew. They worked hard in some very cold and nasty weather to get the job done."

"Company answered immediately when called; our water was off for the whole house due to a leak in a supply line inside a wall. We wanted it fixed as soon as possible, so we were quoted the emergency rates, and our job was scheduled for at or after 4:30PM the same day. Thirty minutes after the first call, we got a call back saying one of their technicians was on the way (3 hours ahead of schedule). When the plumber got to the house, he introduced himself and went straight to work. He quickly identified the problem was with a part accessible from outside the wall, replaced the problem part, helped troubleshoot a leak that started when the water was turned back on, and was done. We were not charged the emergency rate, and he apologized profusely that it had taken slightly over an hour so he had to charge for part of the second hour. That didn't bother us at all; cost was still much less than the minimum cost of an emergency call. The plumber was courteous, efficient, and excellent at communicating what he was doing and why. We will call this company with any future plumbing jobs we have. And hopefully they won't be emergencies!"

"Matthew and his crew were very knowledgeable and professional. They were very thorough in their inspection of my pressurized distribution septic system and prompt in their submission of the county-required report. A few weeks after the inspection, a power outage caused my system to quit working. Matthew came right out and had it working in a few minutes. I will definitely be using Scout Septic in the future for my annual inspection and any problems that might occur."

FAQs for septic system installation and replacement projects in Portland, OR

Most septic system replacements require several days to complete, not including permitting and preparation time. The process begins with site assessment and testing, followed by excavation, component installation, and final inspection. Weather conditions, property accessibility, and inspection schedules can all affect your project timeline. Your contractor can provide a more specific estimate based on your property's unique characteristics.

Standard homeowners' insurance policies don't cover septic system replacement due to age or normal deterioration. Coverage may apply if damage results from specific covered events, but routine maintenance and eventual replacement are generally considered homeowner responsibilities. Review your policy details or speak with your insurance agent to understand your specific coverage limitations.

Look for multiple indicators such as slow-draining fixtures, unusual gurgling sounds in plumbing, sewage odors inside or outside your home, or wet spots in your yard. Unusually lush grass over the drain field area, frequent backups, or recurring repair needs might signal system failure. Addressing these warning signs promptly can prevent property damage and health hazards.

DIY septic installation is not recommended and may violate local regulations. Professional installation ensures compliance with health codes, proper design for your specific site conditions, and appropriate safety measures. The specialized equipment, technical knowledge, and permitting requirements make this a job best left to licensed professionals who can guarantee the system's safety and effectiveness.

With proper maintenance, including regular pumping, a drain field lasts 20 years. Various factors influence system longevity, including household size, water usage patterns, and soil conditions. Regular professional inspections can help determine when replacement becomes necessary. If your system requires increasingly frequent repairs, replacement might be more economical than continuing to address individual problems.
