The right solution depends on the location and extent of the damage, the condition of the existing pipe and access to the sewer line. ImproveSource evaluates those factors before recommending a repair, trenchless solution or traditional replacement.

You shouldn’t have to become a sewer expert to make a good decision. If you’ve been told your line needs replacement, we’ll review the problem, evaluate the available options, and explain what makes sense for your property.
Sometimes replacement is the right answer. Sometimes a different repair method may solve the problem. Our job is to help you understand the difference before the work begins.


Sewer line projects can involve inspection, excavation, specialized equipment, permitting and property restoration. ImproveSource coordinates the work from evaluation through completion so you have one team responsible for the scope, schedule and finished project.

ImproveSource provides residential sewer line repair and replacement throughout Denver and surrounding Front Range communities. We help property owners evaluate sewer line problems, understand repair and replacement options, and determine the appropriate approach based on the condition of the line and the property.
Our service area includes Denver, Lakewood, Littleton, Englewood, Centennial, Highlands Ranch, Aurora, Arvada, Wheat Ridge, Golden, Westminster, Thornton, Northglenn, Broomfield, Commerce City, Parker, Castle Rock, Brighton, Louisville, Lafayette, Erie, and surrounding communities.
Properties throughout the Denver metro area vary significantly in age, sewer pipe materials, soil conditions, tree coverage, and access. Older homes may have clay or cast-iron sewer lines, while the location and condition of the line can affect whether traditional excavation, trenchless replacement, or a localized repair is appropriate.
Not every sewer line problem requires the same approach. Depending on the condition of the pipe, location of the damage, access and other site conditions, your options may include a localized repair, a trenchless solution or traditional excavation.
Trenchless methods can reduce the amount of excavation required and may help preserve landscaping, driveways and other areas above the sewer line. Whether trenchless repair or replacement is appropriate depends on what is actually wrong with the existing line.
Some sewer problems require direct access to the pipe. Significant damage, collapsed or misaligned sections, access conditions and other factors can make traditional excavation the more appropriate solution.
ImproveSource does not start with a preferred method. We evaluate the sewer line problem first, then explain which repair or replacement approach makes sense for your property and why.
Sewer line costs can vary significantly because the right repair depends on what is wrong with the line and what it takes to access and correct the problem. A localized repair may be very different in scope and cost from replacing a longer section of damaged pipe.
Factors that can affect the cost of sewer line repair or replacement include:
Ask what evidence supports the recommended work. You should understand where the problem is, how much of the line is affected, whether repair is a reasonable option, why replacement may be necessary and what the quoted scope includes.
ImproveSource helps you evaluate those questions before the work begins so you can make the decision based on the condition of your sewer line—not simply the first solution proposed.
Tell us what you’ve noticed or what you’ve already been told. If you have a sewer scope, camera footage, inspection report, photos or another contractor’s estimate, we can review those too.
We review the available information and determine what additional inspection or evaluation may be needed to understand the condition of your sewer line.
We explain whether repair or replacement makes sense and discuss trenchless or traditional excavation options when appropriate.
You’ll know what we recommend, why we recommend it, what the work includes and what it will cost before you approve the project.
Once you approve the scope, experienced sewer professionals complete the repair or replacement using the appropriate method for your property.
A sewer line problem does not automatically mean the entire line needs to be replaced. The right solution depends on the location and extent of the damage, the condition and material of the pipe, and whether the problem is isolated or affects a larger section of the line. A sewer scope or camera inspection can help identify the problem so repair and replacement options can be evaluated.
The cost of sewer line replacement varies based on the length and depth of the line, pipe condition, access, excavation requirements, whether trenchless methods are appropriate, and the amount of property restoration required. ImproveSource provides a clear scope and price after evaluating the specific conditions of your property.
Trenchless sewer replacement uses methods designed to repair or replace a sewer line while reducing the amount of open excavation required. It can help minimize disruption to yards, landscaping, driveways and other surfaces, but it is not appropriate for every sewer problem. The condition and configuration of the existing line determine whether a trenchless approach makes sense.
If you've been told you need an expensive sewer line replacement and you're uncertain about the recommendation, a second evaluation can be worthwhile. Ask to see the evidence supporting the proposed work, including where the problem is located, how much of the line is affected and why repair or a less extensive solution is not appropriate.
Yes. Tree roots can enter sewer lines through cracks, failed joints and other openings, where they can restrict flow and contribute to recurring backups. Root intrusion does not necessarily mean the entire sewer line needs replacement. The condition of the pipe and extent of the damage should be evaluated before determining the appropriate solution.
Clay sewer pipe can remain functional for many decades, but age alone does not determine whether it needs replacement. Joint separation, cracks, root intrusion, shifting soil and other conditions can affect an older clay line. A sewer scope can help determine its current condition and whether repair or replacement is warranted.
That depends largely on the replacement method and where the sewer line runs.
The amount of disruption depends on the location of the sewer line and the replacement method. Traditional excavation requires access to the pipe from above, while some trenchless methods can reduce the amount of digging required. Before work begins, the scope should identify where excavation is expected and what restoration is included.
Sewer line work can often be completed during Colorado winters, but weather, frozen ground, site access and the type of work required can affect the project. The conditions at the property should be evaluated to determine the appropriate method and timing.
Sometimes, but standard homeowners insurance often does not cover deterioration or routine failure of the sewer service line itself. Some homeowners have separate service-line coverage that may cover certain underground utility-line failures. Sewer or water-backup coverage is different: it generally addresses damage caused by sewage or water backing up into the home rather than automatically paying to replace the failed sewer line.
Coverage depends on the cause of the damage and the specific policy and endorsements. Before assuming a project is or isn’t covered, homeowners should contact their insurance carrier and review their policy.
The timeline depends on the length and depth of the sewer line, access, replacement method, permitting, site conditions and any restoration required. Once the problem and scope are established, ImproveSource can explain the expected project schedule before work begins.
Responsibility can vary by property and local utility rules. In many cases, the property owner is responsible for at least some portion of the sewer service line connecting the home to the public sewer main. Before approving work, confirm where the problem is located and which portion of the line is the property owner's responsibility.
Coverage depends on your insurance policy and what caused the sewer line damage. Standard homeowners policies may exclude some sewer line failures, while certain policies or endorsements may provide service-line coverage. Review your specific policy or ask your insurance carrier whether the cause and location of the damage are covered.
