The CISRS approach

We don't start with a trench. We start with the condition of your sewer.

Before making a replacement recommendation, we look at what the camera shows, where the defects are, and whether an accessible reroute could be practical for your property.

INSPECT • EVALUATE • REPLACE • REROUTE

Built around one specialty

Cast iron sewer lines are what we focus on.

Many older DFW homes still have cast iron drain and sewer piping beneath the slab, garage, or yard. When it deteriorates, clearing the drain may not solve the underlying pipe defect.

Pinpoint damaged or restricted sections with a sewer camera where access permits.
Evaluate under-slab connections and routes through the yard or outside the home.
Explain whether a localized repair, full replacement, or exterior reroute is feasible.
Provide a defined scope so you know what is being replaced and why.

Discuss Your Cast Iron Sewer Line

Signs your pipe deserves a closer look

Recurring sewer problems may point to failing cast iron.

These symptoms can have more than one cause. A camera evaluation helps distinguish a blockage from damage that may require repair or replacement.

Repeated backups and slow drains

Recurring clogs, multiple slow fixtures, or backups that return after cleaning can indicate a larger sewer-line issue.

Corrosion, scaling, or broken pipe

Cast iron can develop interior buildup, deterioration, cracking, or missing pipe sections that affect wastewater flow.

Under-slab and yard defects

Offsets, standing water, separations, or damaged sections may occur beneath floors, garages, driveways, or landscaping.

Important: Not every old cast iron sewer needs complete replacement. The recommendation should follow the documented condition, access, layout, and repair feasibility of the specific property.

How a CISRS project works

Four steps. One clear replacement plan.

A process built to identify the problem first, evaluate practical routes second, and complete the approved work with documented follow-through.

Inspect the sewer line

Use specialized sewer camera equipment to examine accessible piping, identify visible defects, and locate problem sections where conditions allow.

Evaluate repair and reroute options

Consider the existing connections, pipe condition, depth, slope, site access, and whether an exterior reroute could reduce under-slab work.

Prepare your written estimate

Explain the proposed route or replacement sections, expected access points, included work, restoration scope, and projected schedule.

Replace, test, and complete

Perform the approved repair, replacement, or reroute; coordinate required permits and inspections; and verify the finished work as applicable.

We assess where the sewer is failing before choosing between excavation beneath the home and a possible new path outside it.

Start With an Inspection

There is more than one way to solve a sewer problem

Replace the damaged line—or reroute around it when feasible.

Every property is different. We evaluate the condition and layout before proposing how the new sanitary drain or sewer should be installed.

Option A

Cast iron sewer replacement

Replace damaged piping along an appropriate portion of the existing path.

A replacement may be appropriate when the existing route must be retained or the location of fixtures and connections makes rerouting impractical.

Targeted replacement of documented failed sections
Under-slab, garage, or yard access when required
New approved piping and connection details in the project scope

Option B

Sewer line reroute

Establish an alternate route for eligible fixtures or drain branches.

Where grades, access, code requirements, and the building layout allow, a reroute may move portions of the sewer path outside the home.

Evaluate possible exterior routes and accessible tie-ins
Consider fixture locations, slope, utilities, and city requirements
Compare proposed access and restoration with the replacement plan

Which option applies to your house? That depends on what the inspection reveals and whether the proposed work can be installed and inspected under applicable local requirements.

Master plumber-led evaluation

Talk to someone who can explain what the sewer camera actually shows.

CISRS is centered on identifying cast iron sewer defects and matching the proposed work to the property's actual conditions—not recommending the same fix for every house.

From the initial inspection through the approved repair plan, we focus on clear explanations of the problem, the proposed pipe route, anticipated disruption, and what will be included in the estimate.

Frequently asked questions

Questions about cast iron sewer replacement?

Here's what homeowners often want to understand before choosing a repair or replacement approach.

Ask Us About Your Sewer

Does every old cast iron sewer line need to be replaced?

No. Age alone does not establish that the entire line has failed. The appropriate scope depends on the pipe's condition, location, accessibility, and whether localized repairs are practical.

Can you replace cast iron sewer piping under a concrete slab?

Under-slab replacement may require access through the slab, excavation, or another approved approach. The necessary work depends on the location of damaged piping and the home's layout. We evaluate those conditions before preparing an estimate.

Can the sewer be rerouted outside the house instead?

Sometimes. An exterior reroute must have suitable fixture connections, available space and slope, an acceptable tie-in point, and a route that meets applicable local requirements. An inspection and site evaluation determine whether it is an option.

How do you decide what part of the sewer to replace?

We review available camera findings, problem locations, accessible drain connections, and the existing piping. The written proposal identifies the planned replacement sections or proposed reroute.

What does cast iron sewer line replacement cost?

Pricing varies with the length and depth of pipe, access through concrete or soil, number of connections, excavation, permits, and restoration. We prepare a project-specific estimate after evaluating the line and property.

How long does a sewer replacement take?

Timing depends on the route, amount of excavation, permit and inspection scheduling, access, and the extent of restoration. We discuss the anticipated construction schedule with the proposed scope.

Do you work in Plano, Richardson, and Garland?

Yes. Those cities are a primary focus, and we serve additional Dallas–Fort Worth communities. Call with your address to confirm scheduling and service availability.
