1. Service Plus Plumbing

Website: serviceplusplumbingpdx.com 

Address: 12009 NE Marx St

Contact: (503) 927-4482

Hours: Monday-Friday, 8:00 AM – 4:00 PM

Booking an assessment with Service Plus Plumbing won’t cost a dime just to get them through the door. They offer free in-home estimates and waive all trip fees, giving you an honest diagnosis without financial pressure.

Our neighbor actually hired them recently for a nasty kitchen clog, and their upfront, flat-rate pricing was a massive relief.

Their crew brings nearly two decades of local experience to navigate unique residential plumbing setups. They also use targeted leak detection to find hidden issues before tearing up any walls.

We love that emergency calls typically receive same-day service, which is fantastic when disaster strikes.

However, scheduling a standard visit might be tough if you work normal office hours. They close up shop at 4:00 PM on weekdays, potentially forcing you to take time off. Plus, same-day service isn’t always guaranteed if they’re completely slammed.

Responsive and punctual faucet repair

Very responsive company and perfectly on time. My old faucet drain broke. Well, old faucet plus old house turned out to be a larger  project than anticipated.  They had all the parts needed to fix the problem and all works great. Perfect clean up job too. Recommended.

Prompt and efficient drain service

They had a man at my house the same day I called (later that evening) and started and completed the job  that evening. It included pulling out a leaking garbage grinder and replacing it with a new one and using high pressure water through a special hose fitting to clean the drain all the way to the connection with the sewer.

I was very pleased with their prompt service and good work.

2. Plumbing and Sewer Renewal Specialists

Website: plumbingrenewal.com 

Address: 9350 SW Tigard Street, Tigard

Contact: (971) 803-2042

Hours: Monday-Friday, 8:00 AM – 6:30 PM | Saturday-Sunday, 8:00 AM – 5:00 PM

Plumbing and Sewer Renewal Specialists fixes damaged sewer lines from the inside using cured-in-place pipe lining, so your yard never has to get torn up in the process.

A resin-coated liner gets threaded through the existing pipe and cured in place, essentially building a new pipe inside the old one.

Their crew has served for more than two decades, and backs its CIPP work with a strong warranty rather than a generic guarantee.

Estimates are free, 0% financing is available to soften a big repair bill, and a 24/7 emergency team is on call if something goes wrong overnight.

That said, non-emergency jobs may take a couple of business days to get a technician out for a standard quote. If your issue isn’t an active disaster, that short wait is worth planning around rather than expecting same-day service.

Thorough assessment of drainage obstruction

Adam, was unable to clear the drain because of an obstruction. He identified the location for me so I could dig and find out what the problem is. He was very thorough, but unfortunately this time the drain wasn’t just clogged but a root or some other obstruction.

3. Clog Pro Plumbing & Drain

Website: clogpro.com 

Address: 833 SE Main St. Suite 313

Contact: (503) 479-8168

Hours: Available 24/7

Clog Pro Plumbing & Drain reaches for hydro jetting when a standard drain snake can’t cut through years of built-up sludge, grease, or tree roots. The pressurized water scours the entire pipe wall rather than just punching a hole through the clog.

We once observed their crew clear a completely solid basement pipe, and the sheer force of the equipment was honestly impressive to see up close. 

The company has served since 1993, with 24/7 emergency availability if a backup hits outside normal hours.

Here’s the catch: the 12-month same-as-cash loan comes with strings attached. Miss the 365-day repayment window and a steep 17.99% interest kicks in retroactively, and minimum loan amounts mean this option isn’t available for smaller, cheaper jobs.

Friendly and professional plumbing assessment

Daniel was friendly, professional and courteous. A pleasure to work with. He came in to the home assessed the issue and provided me with options for resolving our plumbing issue; including his recommended solution given the age of our drains. He quickly cleared the drain and left the area clean. He also gave me pointers to prevent future clogs and advised that we may benefit from replacing some of the plumbing given the age. I appreciated the added advice.

4. AAA Drain Cleaning LLC

Website: aaadraincleaningportland.com 

Address: 3064 SE 24th Terrace, Gresham

Contact: (503) 766-5422

Hours: Monday-Friday, 7:30 AM – 5:00 PM

AAA Drain Cleaning LLC keeps things refreshingly simple: free, no-obligation estimates over the phone, no in-person visit required just to get a ballpark figure. They’re a genuinely small, family-run operation, handling most of the actual work.

Their video drain inspections pinpoint exactly where a blockage sits before anyone starts digging or snaking blind. On the other hand, the hydro jetting handles the tougher buildup that a standard auger can’t cut through.

Their clients consistently mention quick turnaround too, and several customers got a technician out the same day or the following morning after calling.

One caveat here: this is very much a residential and small commercial operation, not a crew built for large industrial jobs. If you need enterprise-scale drain work, a bigger outfit with heavier equipment would likely be a better fit.

Quick main drain line clearing

These guys are great, we had a basement main drain issue, where the drain was backfilling our utility sink when the washing machine would pump the was water out. I talked with Steve on the phone and he said it was likely just the line needed to be cleared. Austin came out the next day and sure enough, cleared the line and no more back filling of utility sink. Austin also had some great tips on keeping the lines clean long term.

Thanks guys!

Excellent service for steel drains

Very responsive, called ahead of time and luckily Steve was able to accommodate our schedule. Very quick and clean, I feel he went above and beyond expectations. Definitely I will have them out to maintain our drains! It’s difficult to find someone who can unclog the old steel drain lines some companies won’t.

Also they are a local family owned company, I like to support local businesses whenever possible.

Thank you AAA

5. Cornel’s Plumbing, Heating & Air Conditioning

Website: cornelsplumbing.com 

Address: 14271 NW Science Park Dr

Contact: (503) 558-2045

Hours: Monday-Friday, 7:00 AM – 6:00 PM | 24/7 Live Scheduling

Cornel’s Plumbing, Heating & Air Conditioning has been in the business for over 40 years. Today it’s grown into a full plumbing, heating, and cooling operation, backed by a 100% workmanship guarantee and a 90-minute rapid response promise.

They waive the diagnostic fee entirely if you move forward with the repair. So, paying just to find out what’s wrong doesn’t sting as much.

We also love that their upfront pricing means the cost gets locked in before any wrench touches your sink.

Unfortunately, their seasonal promotions can’t be stacked together, so pick whichever one saves the most rather than expecting to combine deals. Their 90-minute response window is also framed as a goal, not a strict guarantee.

Fast and efficient drain unclogging

Eric was super quick in unclogging our drain, showed me the issue, and was super personable. He was also great about putting boot covers on to keep our floor nice and clean while he worked. Fast, friendly, efficient…I would definitely have him back to fix any future plumbing problems. Thanks Cornell’s!

Professional laundry drain assessment

I always have great experiences with Cornel’s and today was no different. Taylor and Nathan did a great job assessing a slow draining laundry drain, offered multiple options, talked me through each step of the process and delivered as promised. Professional, thorough, clean and considerate! What more could you ask for? Thanks, guys!

Update: Had Brenden out to replace our water heater after the old unit malfunctioned. He was super efficient and had a new unit installed and running in no time flat. Thanks, Brenden!
