Sewer Line Replacement in Alpharetta, GA
When repair isn't enough. Full sewer line replacement using trenchless pipe bursting where the route allows, traditional trenching where it doesn't. Permits pulled with Fulton County, utility tap coordination included.
Full sewer line replacement is the right answer when sectional repairs would just delay the inevitable — a deteriorated cast iron line with multiple failing sections, an Orangeburg line that's deflating across its length, a collapsed line where repair access isn't feasible. The cost is significant but the work is durable: a new PVC sewer line outlasts the homeowner.

When replacement beats repair
The replacement-vs-repair decision usually comes down to four factors:
Material. Orangeburg gets replaced — it can't be reliably repaired. Severely deteriorated cast iron gets replaced when wall thickness is gone across long sections. Aging clay with multiple joint failures usually warrants replacement rather than repairing one joint at a time.
Structural condition. Collapsed sections, severe bellies, or pipes that have separated at joints can sometimes be repaired sectionally, but if multiple sections are involved, replacement is more cost-effective.
Age. A line approaching or past its expected service life with active problems is generally a replacement candidate, even if the immediate symptom could be addressed with a sectional repair.
Recurrence history. If we're at the second or third repair on the same line in a few years, you're paying installments on what will eventually be a replacement anyway.
The camera inspection results, photographed and documented, are what supports the replacement decision. We do not push replacement when repair is the right call.
Trenchless pipe bursting vs traditional trenching
Trenchless pipe bursting is our default when the line conditions allow it. The process: dig a pit at each end of the line (one near the foundation cleanout, one near the municipal connection), thread a steel cable through the existing pipe, attach a bursting head with a new PVC pipe trailing behind, hydraulically pull the bursting head through the line. The head fragments the old pipe outward into the surrounding soil while the new pipe seats into the cleared cavity.
Benefits: no full-length trench, minimal disruption to lawn and landscaping, much faster surface restoration, typically completed in one day for residential lines.
Required conditions: the existing pipe route must be substantially intact (no severe collapses that would prevent the head from pulling through), pipe diameter must be standard, no obstacles in the path that can't be worked around.
Traditional open trench is the answer when trenchless doesn't fit. Lines that are too deep, too shallow, run under structures that can't be excavated under, or have failed routes are open-trench candidates. The work is more disruptive but the result is the same — a new PVC line installed to current code.
Permits, utility coordination, and what's included
Sewer line replacement requires a Fulton County plumbing permit. We pull the permit. We also coordinate with the utility on the tap connection if the work goes to or includes the curb stop or the municipal main connection.
Standard replacement scope includes: site survey, locate-call for buried utilities (gas, electric, fiber), excavation, pipe installation, all fittings and cleanouts, tap connection coordination, backfill to grade, basic surface restoration (dirt to grade, grass seed where it was disturbed).
Not included by default: landscape restoration beyond grass seed, driveway or hardscape replacement if we had to cut through it, retaining walls or grade work, sidewalk or street restoration if the tap connection required municipal work. These are scoped and quoted separately based on what the specific site requires.
Most residential replacements complete in 1–3 working days for trenchless and 3–7 days for traditional trenching.
Older Alpharetta neighborhoods and replacement timing
If your home is in Crabapple, Old Alpharetta, Old Milton, or older sections of Brookwood and your sewer line hasn't been documented or replaced, plan for it eventually. Cast iron from before the 1970s and Orangeburg from anywhere up to the late 1970s are at or past end of service life.
Best timing for replacement: when you're already opening the yard for other work (landscaping, foundation work, irrigation install), or proactively before a sale to remove the issue from buyer inspection. Worst timing: when the line has fully failed and you're dealing with sewage in the basement on a holiday weekend.
If you're considering buying an older Alpharetta home, a pre-purchase sewer camera inspection is one of the highest-ROI inspections you can request. The cost is modest; the information protects you from a potentially major surprise.

Frequently asked
How much does sewer line replacement cost in Alpharetta?
Wide range based on length, depth, method (trenchless vs trenched), and what's at the surface (lawn vs driveway vs landscaping). We give a fixed quote after the camera inspection and site survey. Financing is available for larger jobs through an outside provider.
Will I be without sewer service during the work?
Briefly. On most residential jobs the line is offline for several hours during the pull or trench, then restored. We schedule around your household needs where possible and let you know in advance when you'll need to limit water use.
Can my lawn be saved?
Trenchless replacement preserves most of the lawn — just the pit areas need restoration. Traditional trenching is more disruptive, but we can plan the route to minimize impact and restore with grass seed at grade. Mature landscaping (large shrubs, established trees) is harder to restore than turf.
Does my homeowners insurance cover this?
Almost never. Sewer line replacement is generally treated as deferred maintenance and excluded from standard policies. Some carriers offer a separate sewer-and-water-line endorsement for an additional premium — check your policy or call your agent.
How long does a new sewer line last?
PVC sewer lines installed to current code typically last 50–100 years. The new line outlasts the homeowner in most cases.
