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

Most under-slab work is detective work, and the construction at the end stays small. Depending on what the footage shows, some of the pieces below belong to your Dunwoody job and some do not, and your technician walks through them before the crew starts:

Camera mapping gives a distance for every crack, root mass and offset joint.
A floor locator moves that distance onto your flooring, so any opening stays small.
Root removal and cleaning bare the pipe wall, since resin bonds only to a cleaned surface.
Lining through a cleanout seals a cracked stretch from inside, so the concrete above stays whole.
A narrow slab opening is held for breaks, offsets or collapses that no liner can span.
New PVC pipe replaces the failed length after the soil under the floor has been opened.
A flow test runs water through the repair, and the patch waits until it passes.
Slab patching closes the floor after the test passes.
Permit check starts with a call to the City of Dunwoody ahead of any cutting.

When You Need Under-Slab Sewer Line Repair in Dunwoody

If your house sits on a slab, the failing pipe is usually hidden, so the house itself gives the warning. Once a floor feels different, an odor appears or drains misbehave, book a camera, since a broken pipe beneath the foundation only gets worse.

Signs of a Sewer Pipe Leaking Under Your Dunwoody Slab

A warm, damp or spongy spot on the floor may point to wastewater seeping into the concrete from below.
Sewer smell with every trap full hints that a crack is letting gas rise through the slab.
Every drain slowing at once points to a restriction on the main run, part of which may sit under the floor.
Fine new cracks in tile or concrete may follow soil carried off by a leaking pipe.
Backups that keep returning call for a camera well before anyone talks about cutting the floor.

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

Dunwoody has many older houses and a large band of 1980s and 1990s builds. Three local facts, from pipe age to permit, shape a repair below the floor.

Houses From Before 1980

Census figures put 44.1% of Dunwoody homes before 1980, so a large share of drain lines is past 45 years. Orangeburg, clay and cast iron were all common then, and any of them under the floor eventually cracks, corrodes or loses shape. Early warnings stay hidden by a slab, which is why the entire line is scoped before concrete is even discussed. The connection at the house gets checked too.

The 1980s and 1990s Lines

Another 30.2% of Dunwoody homes were built from 1980 through 1999, so their drains are about 25 to 45 years old. Roots favor joints and small cracks at that age, and PVC can crack too. Lining cannot raise a pipe, so a sag under the floor means a dig to rebuild the grade, quoted with the slab work on a line of its own. A scope costs $200 to $500 and shows how far the damage reaches.

Property Lines and the Permit

The line inside the property boundary usually falls to the owner, and 56.2% of Dunwoody homes are owner-occupied. DeKalb County Watershed Management lists a 24-hour emergency line, 770-270-6243, for sewer backup reports. Before a floor is opened, the office asks the City of Dunwoody about a permit and files one when it applies, and the estimate lists that step. The estimate also names the stretch of pipe the work covers.

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

Quoting a Dunwoody floor repair starts with a $200 to $500 scope, because no one can price a pipe that has not been seen. Footage then sets your sewer line repair under concrete slab cost. Lining is the lighter path, a slab opening adds excavation, and concrete is broken only when a liner will not do the job. The final figure arrives with the inspection results.

Job or size band	Typical price	Key variables
Camera run beneath the floor	$200 to $500	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	material, length, roots
Camera run plus lining	$2,700 to $7,500	bends, wall condition
Slab opening and excavation add-on	$400 to $1,200 or more	depth, floor surface
Camera run plus full replacement	$4,200 to $12,500	method, cover above the pipe

Pipe that can be lined keeps the floor intact, which is covered under trenchless sewer repair. A run that failed along its length belongs with sewer line replacement. The sewer camera inspection page covers the scope in detail, while the sewer line repair cost guide puts every method side by side.

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

A Dunwoody under-slab repair runs five steps, from the first phone call to a patched floor, and the footage decides how much concrete the crew handles.

1. Call and Site Visit

Use the phone or the quote form, and a visit gets booked at your Dunwoody home. The estimator listens for slow drains, soft spots in the floor and the date it all started, then locates the cleanout and studies the layout. Before any equipment appears, the plan is laid out and a free written estimate puts a separate price on every step.

2. Camera Run Beneath the House

A waterproof camera travels from the cleanout and records each crack, root mass and offset along the pipe, with you at the monitor. Playback reveals whether the fault sits beneath the house or out in the yard. Next a surface locator paints the break on your floor, which keeps any opening right on top of the damage.

3. Floor Marking and Written Options

With the break located, the choices are written out side by side. A liner threaded in from the cleanout keeps the floor intact. A narrow opening plus new PVC suits a collapsed or offset section. Each option lists its price, its working time and the concrete work involved, so the decision rests on numbers you can read. Nothing proceeds without your signature.

4. Lining or a Small Opening

A pipe that can take a liner is cleaned and fitted with a resin sleeve, which cures in about two hours. A pipe that cannot is reached through a small cut over the mark, and the failed length is replaced with new PVC while dust stays contained. Trenchless replacement as a whole usually takes one to three days, and opening the floor adds curing time.

5. Water Test, Patch and Paperwork

Water is run through the line before anything is covered, and the crew watches it carry. After a pass, the patch is poured and the area cleaned. If the City of Dunwoody requires a permit, the filing and the inspector’s visit are handled for you. Attached to the estimate are the written guarantee terms, which spell out what backs the repair.

Under-Slab Sewer Line Repair FAQs: Dunwoody, GA

What happens if a sewer line breaks under your house?

Wastewater soaks the soil and concrete and can back up into the home. A camera locates the break first, and lining or a narrow opening follows.

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

The camera run is $200 to $500, and lining runs $2,500 to $7,000. Concrete work adds $400 to $1,200 or more on top, and the under-slab total is set once the inspection is done.

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

Often, when the pipe is cracked or invaded by roots but still follows its route, because a liner can go in from the cleanout. A collapsed or sagging section needs a small opening.

What is a slab sewer leak?

A crack or open joint in a drain buried under a concrete floor. Water, odor and floor cracks can point to the wrong place, so slab sewer leak repair starts with a camera.

Does homeowners insurance cover sewer repair under the house?

Roots, age and wear fall outside most standard homeowners policies. A service line endorsement may help, with limits that often run $10,000 to $20,000, so ask before work begins.

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

The office asks the City of Dunwoody whether a permit applies and files one when it does, and the step shows up in the written estimate.

How long does an under-slab sewer repair take?

Resin cures in about two hours after the pipe is cleaned. Most trenchless replacements are done within one to three days, and an opening and patch add time for the concrete to set.
