What Under-Slab Sewer Line Repair Involves in Alpharetta, GA

A repair beneath a slab is mostly detective work followed by a small, planned amount of construction. Depending on what the recording shows in an Alpharetta house, the job can include any of these pieces:

Locating the fault starts with a camera that reports the distance to each crack, root mass or offset joint.
A surface locator pins that distance to a spot on your floor, so any opening stays as small as possible.
Root cutting and cleaning prepare the pipe wall, since a liner bonds only to a cleaned surface.
Lining from a cleanout seals cracks under the house with a resin sleeve and leaves the concrete uncut.
A narrow slab opening is saved for breaks, offsets or collapsed pipe that a liner cannot cross.
New PVC in the gap replaces the failed length once the soil beneath the floor is exposed.
Water testing proves the line holds before anyone mixes a patch.
A concrete patch seals the opening after the water test.
Permit filing follows a question to the City of Alpharetta about whether your repair needs one.

When You Need Under-Slab Sewer Line Repair in Alpharetta

Alpharetta owners seldom see the pipe that fails. They notice what it does to the house, and a few changes in the floor, the air or the drains justify booking a camera. A sewer line break under foundation concrete only gets worse while water travels further.

Signs of a Sewer Pipe Leaking Under Your Alpharetta Slab

A patch of floor that feels warm or damp can mean wastewater is soaking the concrete from below.
Sewer odor even though every trap is full points to a crack venting gas up through the slab.
Several drains slowing together suggests a restriction on the main run, which may pass beneath the house.
New hairline cracks in tile or concrete can follow soil washed away by a leaking pipe.
A stoppage that returns after snaking deserves a camera before anyone considers cutting the floor.

Alpharetta Sewer Lines and Under-Slab Sewer Line Repair: Pipe Age, Settling, Ownership

Three Alpharetta facts shape how a repair under a floor is planned, from the age of the pipe to who owns which stretch of it.

Pipes From the 1980s and 1990s

Census figures show 56.6% of Alpharetta homes went up in the 1980s and 1990s, so most drain lines there have spent 25 to 45 years underground. Joints draw roots by that age, and PVC may split where it was stressed. Under a slab the first warning is often indirect, like a damp corner or a slow tub, so the whole line gets scoped before anyone decides concrete must come up.

Newer Slabs and Settling

Another 16.1% of Alpharetta homes have been built since 2010. A drain laid on loosely packed fill can sink into a belly, and waste then collects there years after closing. Lining cannot raise a sagging pipe, so a belly under the floor is quoted as a dig that restores the grade, with the slab work shown as its own line.

Public Main, Private Lateral and the Permit

A 2017 City of Alpharetta notice says Fulton County hires private companies to clear grease, roots and debris from sewer lines city-wide, which covers the public side. A Fulton County laterals flyer puts the owner in charge of repairing the lateral that connects the house with the property boundary. Before opening a floor, we ask the City of Alpharetta whether a permit applies and file it. Your estimate lists that step, so the paperwork never surprises you midway through the job.

How Much Does Under-Slab Sewer Line Repair Cost in Alpharetta, GA?

The sewer line repair under concrete slab cost in Alpharetta starts with a scope of $200 to $500, because no one can price a pipe they have not seen. The ranges below cover the pieces of a typical job. Breaking and patching concrete is added only when lining will not work, and the final under-slab figure is quoted after the camera inspection.

Job or size band	Typical price	Key variables
Camera run beneath the floor	$200 to $500	line length, cleanout access
Spot repair of one failed section	$800 to $3,000	depth, cover above the pipe
Lining without cutting concrete	$2,500 to $7,000	pipe material, length, roots
Camera run plus lining	$2,700 to $7,500	pipe condition, bends
Slab opening and excavation add-on	$400 to $1,200 or more	depth, floor surface to cut
Camera run plus full replacement	$4,200 to $12,500	method, cover above the pipe

Compare these ranges with trenchless sewer repair when the floor can stay intact. Read about sewer line replacement when the pipe has failed along its length. The sewer camera inspection page explains how the scope is run. Our sewer line repair cost guide covers every method side by side.

Our Under-Slab Sewer Line Repair Process in Alpharetta, GA

Five steps carry an Alpharetta under-slab job from your first call to a patched floor, and the camera result decides how much concrete is touched.

1. Call and Site Visit

A call or a quote form request gets your Alpharetta visit on the calendar. We ask where the drains run slow, where the floor feels wrong and when the trouble began. A tech then walks the house, finds the cleanout, looks at the plumbing layout and explains the plan before touching a tool. The free written estimate that follows prices each step separately.

2. Camera Run Beneath the House

A waterproof camera travels down the pipe from the cleanout and records every crack, root mass and offset along the way. The footage shows whether the fault sits under the slab or out in the yard, and you can watch it with the technician. A locator then marks the break on your floor, so any opening is cut where the problem is and nowhere else.

3. Floor Marking and Written Options

With the break located, we write the choices side by side. A liner from the cleanout leaves the floor alone. A narrow opening and new PVC suit a collapsed or offset section. Each option shows its price, its repair time and the concrete work it needs, so you can pick with the numbers in front of you.

4. Lining or a Small Opening

If the pipe can be lined, the crew cleans it, pulls in the resin sleeve and lets it cure in about two hours. If it cannot, we cut a small opening over the mark, replace the failed length with new PVC and keep the dust contained. Replacing the line by trenchless means takes one to three days in most cases, and an opening adds some curing time.

5. Water Test, Patch and Paperwork

Before closing anything, we run a water test through the line and watch it carry. Once it passes, the crew pours the patch and cleans the work area. When the City of Alpharetta requires a permit, we file it and meet the inspector. Guarantee terms in writing arrive with the estimate, so you learn what backs the repair before work starts.

Under-Slab Sewer Line Repair FAQs: Alpharetta, GA

What happens if a sewer line breaks under your house?

A sewer line break under foundation floors lets wastewater soak the soil and concrete, and it can back up into the home. Under-slab sewer line repair starts with a camera to locate the break, then lining or a narrow opening fixes it.

How much does sewer line repair under a concrete slab cost in Alpharetta?

Alpharetta homeowners pay $200 to $500 for the camera run, and lining runs $2,500 to $7,000. Breaking concrete adds $400 to $1,200 or more, so the final under-slab figure is quoted after the camera inspection.

Can a pipe under the floor be repaired without breaking the concrete?

Many cracked or root-invaded pipes can be lined from a cleanout, which leaves the slab alone. A collapsed or sagging pipe cannot be lined, and then under-slab sewer line repair needs a small opening.

What is a slab sewer leak?

A slab sewer leak is a crack or open joint in a drain pipe buried beneath a concrete floor. Slab sewer leak repair begins with a camera, since water, odor and cracks in the floor can point to the wrong place.

Does homeowners insurance cover sewer repair under the house?

A standard homeowners policy excludes wear, age and roots from a sewer repair claim. A service line endorsement may help, with limits of $10,000 to $20,000, so ask your insurer before work begins.

Do I need a City of Alpharetta permit for work under my floor?

We ask the City of Alpharetta whether a permit applies to your under-slab sewer line repair and file it when one does. The step appears in your written estimate.

How long does an under-slab sewer repair take?

A liner cures in about two hours once the pipe is cleaned. Most trenchless replacements finish within one to three days, and opening and patching a slab adds time for the concrete to set.
