When to Call
Drain and sewer problems we solve every day
A small drain issue today is a sewage backup tomorrow. Catch these symptoms early and the fix is usually quick and cheap.
-
Slow drains
Standing water in sinks, tubs, or showers means the line is partially blocked — usually grease, hair, or roots.
-
Recurring clogs
If the same drain keeps clogging, a snake won't fix it. You need a camera and a hydrojet.
-
Gurgling toilets or drains
Air trapped behind a partial blockage in the main line — an early warning of a full backup.
-
Sewage smell
A dry trap, a venting issue, or a cracked sewer line. All worth a same-day check.
-
Multiple fixtures backing up
When more than one drain backs up at once, the problem is in the main line — not the fixture.
-
Wet spots in the lawn
Lush green patches or soggy ground over the sewer line is a classic sign of a leaking or broken main.

Phoned mainstream to handle an extremely bad clog, in our septic line. Nolan came out to tackle this problem. From the start, Nolan did an awesome job. He was knowledgeable, polite and, totally professional about the situation. I am beyond satisfied with the job he did. If i need Service in the future, i will be calling Mainstream..!!!!!

Pierce was here within an hour, and got our clogged drain card for very efficiently. He very clearly advised me without pressure on additional needs for my 121 old house's aged plumbing. He offered a reasonable estimate for me to consider. I will use Mainstream for future needs, and request Pierce if he is available. Thank you.

Drains & Sewers — Frequently Asked Questions
How fast can someone get to my house when a drain backs up?
Sewer backups and active flooding get priority dispatch 24/7 — including weekends and holidays. We don’t charge extra for after-hours calls. Most non-emergency drain calls in Spokane and Coeur d’Alene are scheduled same-day or next-day.
Do you camera-inspect every job?
Every sewer job, yes. Drain cleaning calls inside the house often don’t need a camera — but if a drain keeps re-clogging or you suspect a problem with the main line, we’ll run the camera and show you the video. No camera fee on most service calls.
Snake, jet, or replace — how do you decide?
It depends on what we see in the camera. Roots and grease come back fast after a snake — those need hydrojetting. Cracked or offset pipe needs spot repair or trenchless lining. Collapsed pipe needs replacement. We’ll show you the footage and walk through the options.
Is the work warrantied?
Every repair includes a 1-year Mainstream labor warranty plus the full manufacturer parts warranty. Sewer line replacements and CIPP liners come with extended warranties — typically 10–50 years on the liner itself.
Do you offer financing?
Yes. We offer flexible financing — including no-interest plans for qualified customers — so a sewer emergency or planned upgrade doesn’t have to wait. Our team walks you through the options during the visit.
*Offers cannot be combined with other promotions or applied to dispatch fees. No cash value. Must present offer at time of service. Call for details.
