Sewer Inspection, Repair & Replacement
From the first camera inspection to a brand-new sewer line, one local team handles the whole job — and we always show you the problem before we recommend a fix.
Sewer Camera Inspection
We run a camera through your sewer line to find cracks, roots, offsets, sags or collapsed sections — so you know exactly what is wrong before any digging.
- See the problem on video
- Pinpoint the location and depth
- Clear repair or replace recommendation
Sewer Line Repair
When the damage is limited to one section, we excavate and repair just that part of the pipe — restoring proper flow without replacing the whole line.
- Cracked or broken sections
- Offset and separated joints
- Root-damaged sections
Sewer Line Replacement
Collapsed, crushed or badly deteriorated sewer lines are replaced with new pipe, properly bedded and sloped for reliable drainage for years to come.
- Old clay or cast-iron lines
- Collapsed or crushed pipe
- Repeated backups and failures
Sewer Cleaning
We clear roots, grease and debris from your main sewer line by snaking and rodding — and we tell you if a camera inspection shows a bigger problem.
- Root removal by snaking
- Grease and debris clearing
- Recurring clog diagnosis
Sewer Backup & Emergencies
Sewage coming up through a floor drain or toilet is an emergency. We respond fast to get your line flowing and stop further damage to your home.
- Same-day service often available
- Main line clogs cleared
- Root cause found, not just patched
Main Drain Clogs
When every drain in the house is slow or gurgling, the problem is usually the main line. We locate the blockage and clear it properly.
- Multiple slow drains
- Gurgling toilets and drains
- Basement floor drain backups
A Family Built on Honest Plumbing
Imperial Plumbing isn’t a big corporate chain — we’re your neighbors. Founded and operated by a local family with over 20 years of hands-on plumbing experience, we’ve built our reputation one honest job at a time across Centennial, Denver, and the surrounding communities.
Sewer work is a big decision, so we keep it simple: we inspect the line, show you what we found, and give you a clear price before any work begins. If a repair will do the job, we won’t sell you a replacement.
Signs Your Sewer Line Needs Attention
Sewer problems usually start small. If you notice any of these, book a camera inspection before a small issue becomes a backup.
Multiple Slow Drains
Sinks, tubs and showers draining slowly at the same time often point to a problem in the main sewer line.
Gurgling Toilets
Bubbling or gurgling sounds when you flush or run water can mean air is trapped by a blockage or damaged pipe.
Sewage Backups
Water or sewage coming up through a basement floor drain or toilet needs attention right away.
Sewer Odors
A sewage smell inside the house or in the yard can be a sign of a cracked or leaking sewer line.
Soggy or Greener Lawn Patches
Unusually wet or lush spots over the sewer line can mean wastewater is leaking into the soil.
Clogs That Keep Coming Back
If the line keeps clogging after cleaning, roots or pipe damage are usually the real cause.

Sewer Repair Questions Answered
How do I know if my sewer line needs repair or replacement?+
A sewer camera inspection is the only reliable way to know. It shows whether the problem is a single damaged section that can be repaired or a line that is failing along its length and should be replaced. We show you the footage and explain the options.
What causes sewer line damage?+
The most common causes are tree roots growing into joints, older clay or cast-iron pipe deteriorating with age, ground movement that shifts or separates pipe, and grease buildup that leads to repeated clogs.
Can you clear roots from my sewer line?+
Yes. We clear roots by snaking and rodding the line. If roots keep coming back, it usually means the pipe is cracked or separated — a camera inspection will show whether a repair is needed.
How long does a sewer line replacement take?+
It depends on the length and depth of the line and what is above it. After the inspection we give you a clear timeline along with your quote, so you know what to expect before work begins.
Is there a charge for a service visit?+
There’s a $79 service call fee — waived with any approved work. It covers coming out to assess your sewer problem and provide an estimate.
What areas do you serve?+
We serve Centennial, Denver, Aurora, Parker, Greenwood Village, Englewood, Lakewood, Morrison, Golden, Thornton, Westminster, Lone Tree, Castle Pines, Castle Rock, and surrounding areas.
