Emergency Drain Cleaning & Unclogging in Boulder, CO
A slow kitchen sink is annoying. A backed-up main line is an emergency. Boulder Express Plumbing clears both, from a single stubborn drain to a fully backed-up sewer main, using cabling for routine clogs and hydro jetting when a line needs a full clean-out rather than a quick poke-through.
The Boulder Factor.
Older Boulder homes, particularly in the Mapleton Hill and University Hill areas, sometimes still run on original clay sewer laterals. Tree roots find their way into the joints of these older lines over decades, and what looks like a simple clog is often root intrusion that keeps coming back until the root growth itself is cleared.
Kitchen drains are the other recurring culprit, especially in homes with garbage disposals handling more grease and food waste than the line was designed for. Grease cools and hardens against the inside of the pipe long before it reaches the street, narrowing the line gradually until a clog finally forms.
What to Look For.
Water draining slower than normal in one or more fixtures.
Gurgling sounds from a drain when another fixture is used.
Multiple drains backing up at the same time (a main-line symptom).
A recurring clog that comes back a few weeks after snaking.
Sewage smell near a floor drain or basement fixture.

Getting to the Root Cause.
For a single slow drain, cabling usually clears it in one visit. When a clog keeps recurring at the same spot, or multiple fixtures back up together, we run a video sewer camera down the line first to see whether it's a simple blockage or root intrusion in an aging clay lateral.
The camera also tells us the pipe's actual material and condition, which matters for older Boulder homes where a previous owner may have done a partial repair with a different pipe type. Mixed materials in one line is common enough in older housing stock that we check rather than assume.
Fixing It the Right Way.
Drain Snaking / Cabling.
- Standard fix for a single slow or clogged drain.
- Fast, usually same-visit.
- Doesn't remove root growth from the pipe walls.
Hydro Jetting.
- High-pressure water clears grease buildup and root intrusion the cable can't reach.
- Better fit for a clog that keeps coming back.
- Recommended after a camera inspection confirms it's the right tool for the pipe's condition.
Understanding the Price.
We don't publish flat prices because the factors above genuinely change the number. Free on-site estimates cover non-emergency work, and for active emergencies we give you an upfront price before any repair begins. Call (303) 552-3896 for your real number.
What Homeowners Ask.
A drain that clogs at the same spot repeatedly, weeks or months apart, usually means something structural in the pipe itself, most often root intrusion in an older clay lateral. Cabling clears the immediate blockage but not the roots growing into the joint. That's when hydro jetting or a camera inspection makes sense.
For most pipe materials, yes, when the pressure is matched to the pipe's actual condition, which is exactly why we camera-inspect first on older lines rather than jetting blind.
We'd rather you didn't. Chemical drain cleaners can damage older pipe materials and make it harder and more hazardous for a technician to cable or camera the line afterward. A plunger is fine for a single fixture. Beyond that, call us.
Often Booked Together
A clog that keeps returning despite cabling is usually a sign hydro jetting is the better tool, and we'll often confirm that with a camera inspection first. If a specific fixture like a toilet or garbage disposal is the actual source, those get handled as their own repair rather than just a drain clearing.
Whether it's one slow drain or a backed-up main line, call Boulder Express Plumbing and we'll get it moving again the same day. If the camera finds root intrusion or aging pipe material, we'll show you exactly what we found before recommending anything beyond a standard cleaning.
