A sewer line carries all the waste water out of your home. When it cracks, clogs, or collapses, the trouble shows up fast. You may see sewage in a floor drain, slow drains in every room, or soggy ground in the yard.
Pastgrateful Plumbing is a referral service. We do not do the repair. We connect homeowners in Denver and the Denver area with independent local providers who handle sewer line repair and blocked pipe services. This page tells you what to do first, what to avoid, and what drives the price. Request an estimate, ask for it in writing, and compare your options before you agree to any work. The steps below use plain words and short lists.
Sewage Backing Up? Safe First, Then Quote
Raw sewage can carry germs. Treat any backup as a health risk. Stay calm and follow these steps.
Do these things
- Stop using water. Skip the shower, sinks, dishwasher, and washing machine.
- Keep children and pets out of the wet area.
- Open windows if the smell is strong.
- Take photos of the damage before you clean anything.
- Wear gloves and boots if you must step into the area.
Do not do these things
- Do not flush toilets again and again to "push it through."
- Do not pour harsh chemical cleaners into a backed-up line. They can burn skin and harm pipes.
- Do not touch wet electrical items or outlets near standing sewage.
- Do not dig near the yard line before utilities are marked.

Signs the Main Line Is Failing
Blocked pipe services are often needed for a simple clog. A sewer line problem looks bigger. Watch for these clues:
- More than one drain is slow or gurgling.
- A basement floor drain bubbles or backs up.
- Sewer smells in the house or yard.
- Lush, green patches or soft, sunken ground over the line.
- Cracks in a slab or foundation walls.
One slow sink is usually a local clog. Several slow drains at once point to the main line.
What Harms a Sewer Line
Roots are a common cause. They push into small joints, then grow into a thick mass. Older clay, cast iron, and fiber pipe can crack or sag with age. Grease and wipes build up and form blockages.
Weather matters too. Heavy snow loads and a fast spring melt soak the soil. Shifting, wet ground can pull joints apart. Dry air and hard freezes can also move soil around a pipe. Newer homes can still have trouble if the trench was packed poorly.
How Providers Find the Problem
A good provider looks before they quote. Most use a small camera on a flexible cable. It runs through a cleanout or drain and shows the pipe from inside. They can spot cracks, breaks, roots, and low spots where water pools.
Many also use a locator to mark the depth and path of the pipe above ground. Ask for a copy of the video or photos. That record helps you compare quotes.
Know the Price Drivers
Sewer work varies more than most plumbing jobs. These factors move the price:
- How long the damaged section is.
- How deep the pipe sits.
- What lies above it, such as a driveway, patio, or trees.
- The repair method.
- Permits, inspections, and restoring the surface.
Frozen or very wet ground can add time. Ask the provider to list each item in the quote.
Repair Options
The right fix depends on the camera findings. A fair provider explains why they picked it.
Spot repair
If only one short section is bad, a crew can dig, cut it out, and replace it. It is often the lower-cost path for a single break.
Lining
A resin-soaked liner is pulled into the old pipe and cured in place. It needs little digging. It suits pipes that are still mostly intact.
Pipe bursting
A new pipe is pulled through as the old one is broken apart underground. It fits long runs with few access points.
Full replacement
When the pipe is crushed, badly sagging, or failing in many spots, open trench replacement may be the sound choice. It is the most disruptive but can last for decades.
Permits and Property Lines
Most areas require a permit for sewer work, and many require an inspection before the trench is closed. Ask who pulls the permit. The provider usually does, and the cost shows up in the quote.
Property lines matter. In many places you own the pipe from your house to the street connection or the main. The city or utility may own the rest. Check with your local utility before work begins, because the responsible party can change the plan.
Seasons and Timing
Winter can make digging slow and costly. Frost, snow, and ice limit access. Spring melt can overload lines and expose weak spots. Summer and fall are often easier for planned digging, though busy seasons can fill schedules. Hail and storms can bring debris and runoff into yards and drains.
If the line is leaking or backing up now, do not wait for perfect weather. Ask the provider what can be done safely first and what can be scheduled later.
Questions to Ask the Provider
- Will you run a camera first and share the video?
- Is the quote for the whole job, including permits and surface repair?
- Which repair method do you suggest, and why?
- What could change the price once work starts?
- Is there a warranty on the work, and is it in writing?
- Will my yard, driveway, or landscaping be restored?
Some policies may cover sudden damage. Check your policy, and ask whether the provider can help document the damage for a claim.
Ask for It Written
A verbal number is easy to forget and hard to prove. Get a written quote that names the work, materials, permits, and exclusions. Compare at least two if you can. A calm, clear quote is a good sign.
What's Included
Camera Inspection
A provider runs a camera through the line to find cracks, roots, and low spots.
Spot Repairs
Short broken sections can be cut out and replaced without redoing the whole line.
Trenchless Options
Lining and pipe bursting may reduce digging when the pipe and site suit them.
Full Replacement
Badly damaged or collapsed lines may need a new pipe run from the house outward.

No obligationSewer Line Repair Services FAQ
How do I know if my sewer line is broken?
Look for several slow drains at once, sewage smells, gurgling, or a backup in a basement floor drain. Wet or sunken spots in the yard can also be a sign. A camera inspection by a local provider confirms it.
How much does sewer line repair cost?
In the U.S., spot repairs often run about $1,500 to $5,000, while full replacement can reach $15,000 or more. Length, depth, access, and permits change the price. Ask the provider for a written quote that lists each item.
Does homeowners insurance cover a broken sewer line?
It depends on your policy. Some policies may cover sudden damage, but wear, age, and roots are often excluded. Check your policy, and ask the provider about help documenting damage for a claim.
