Angi and HomeAdvisor are one company, and This Old House says its sewer replacement figures are “based on estimates from Angi,” so matching numbers are one data set, not confirmations.

Job	National figures (publisher, page date)
Sewer spot repair	$600 to $1,050 for a cracked pipe (Angi, Aug. 3, 2026, and HomeAdvisor, June 19, 2026). “General line repairs” $1,000 to $4,000 (Angi clog guide, Oct. 8, 2026).
Full sewer line replacement	Average $3,319; most pay $1,388 to $5,323; $50 to $250 per foot (Angi, Aug. 3, 2026). This Old House rounds this to $3,320 (March 30, 2026) but says “around $5,000” in another guide (April 10, 2026); HomeAdvisor (June 19, 2026) gives two averages, $3,319 and $2,600.
Sewer pipe lining (CIPP)	$1,900 to $6,000 a job, average $2,900, or $135 to $150 per foot (Angi trenchless guide, July 10, 2026). $90 to $250 per foot (Angi, Aug. 3, 2026; HomeAdvisor, June 19, 2026).
Pipe bursting	$60 to $200 per foot (Angi, Aug. 3, 2026; HomeAdvisor, June 19, 2026). $150 to $190 per foot “along with the lining” (Angi trenchless guide, July 10, 2026).
Sewer camera inspection	$250 to $400 for a 50 to 100 foot line (Angi camera guide, July 9, 2026; its $996 headline average sits above most of its own table). $100 to $500 (This Old House, March 30, 2026). No guide we checked prices a pre-purchase sewer scope inspection separately.
Sewer line cleaning (main line clog)	Average $380, most pay $187 to $572; snaking alone $100 to $250 (Angi clog guide, Oct. 8, 2026).
Hydro jetting	Average $475, normally $350 to $600, “as little as $100 or as much as $2,000” (Angi hydro jetting guide, Nov. 24, 2025).
Two-way sewer cleanout	Average $2,700, commonly $1,400 to $3,500 (Angi cleanout guide, Nov. 21, 2025). Any cleanout $500 to $2,000, two-way “up to $3,500” (Angi installation guide, Nov. 27, 2025).
Backwater valve	$135 to $1,000 in new construction; a retrofit costs more, amount not given (This Old House, June 5, 2026).
Grinder pump installation	Average $3,000, normally $2,000 to $4,000 (Angi, Jan. 9, 2025). No national repair price found; see grinder pump repair.

Grand Strand Water and Sewer Authority (GSWSA) sewer fees per unit: $2,735 impact, $1,020 tap, $80 inspection, plus supplemental impact fees in some areas. Georgetown County Water and Sewer District (GCWSD, Murrells Inlet, 2026-27): $1,893 impact plus a $120 administrative fee.
Septic line repair	$1,500 on average (Angi, Nov. 24, 2025). A broken pipe “about $600 on average” (HomeAdvisor, Oct. 29, 2025).
Main water line repair	Average $1,025, most pay $354 to $1,696, though the same page also says $989 (Angi, Nov. 23, 2025). Main water line leak $500 to $4,000 (This Old House, June 6, 2026).
Main water line replacement	Average $1,710, normally $647 to $2,828, $50 to $150 per foot (Angi, Nov. 25, 2025).

Angi’s per-foot lining price, over the 50 to 75 feet it calls typical, tops its own $6,000 per-job figure.

What Grand Strand plumbing websites publish

Grand Strand plumbing websites we checked on Nov. 5, 2026 publish their own figures, and they conflict, even within one site. They are not quotes or our prices.

Job	Lowest figure published	Highest figure published
Camera inspection	$150	$400
Main line cleaning	$250	$500
Hydro jetting	$350	$600
Spot repair	$500	$3,000
Trenchless repair or lining	$2,500	$10,000
Full replacement	$3,000	$18,000
Water line replacement	$1,500	$4,000

One site prices spot repair at $500 to $2,500 on one page and $1,000 to $3,000 on another; a second lists full replacement at $3,000 to $9,000 and $3,000 to $7,500 on two pages. Several long-established local companies publish no prices.

What changes sewer line costs on the Grand Strand

Depth and length. GSWSA’s Sewer System Standards (July 2026) set new laterals 36 inches to 4 feet deep; older lines vary. Length counts too: This Old House (April 10, 2026) prices a 25 to 35 foot line at $1,250 to $8,750 and a 75 to 100 foot line at $3,750 to $25,000.

Groundwater and dewatering. USDA soil survey data puts the water table within 2 feet of the surface, for part of the year, on 79.5% of Horry County’s mapped acreage. A trench that fills with water generally has to be pumped down before pipe can be bedded to grade, which adds equipment and time.

Sand, muck and stone bedding. Where a trench hits “muck, quicksand, soft clay, swampy” or similar ground, GSWSA’s standards require replacing it with gravel or crushed stone no larger than 3/4 inch. Coastal soil ranges from poorly drained Leon fine sand to fast-draining dune sand, depending on the block.

Driveways, slabs, landscaping and restoration. Concrete and plantings over the line can outprice the pipe itself: Angi (updated Aug. 3, 2026) puts excavation at $50 to $200 per foot but work under a slab at $300 to $350 per foot. Two quotes can differ only because one leaves out backfill, sod or concrete patching.

Cleanouts. GSWSA’s standards call for cleanouts at the property line, 5 feet from the building, at bends over 45 degrees and every 75 feet at most on straight runs. An older line may need some added.

Schedule 40 PVC. GSWSA requires Schedule 40 PVC (or DWV), with no rubber couplings, for new laterals on the owner’s side, beyond the right-of-way or property line. It is thicker-walled than the SDR 35 PVC the state code also allows, so check which pipe each quote prices.

Permits and inspection fees. South Carolina’s 2021 residential code makes replacing concealed pipe new work needing a permit and inspection; stopping leaks and clearing stoppages are exempt. Georgetown County (Murrells Inlet) charges $30 on the first $1,000 of value plus $6.50 per added $1,000, so an $8,000 job carries a $75.50 permit before any plan-check fee. We have not confirmed Horry County’s or the cities’ plumbing permit fees. We pull the permits and schedule the inspections.

SC811 locates. We request SC811 locates for public lines, which utilities have 3 full working days to answer; SC811 does not mark private lines, so we trace yours with the camera’s locator.

Condos and shared lines. Condo units often share one building sewer, and 49.2% of North Myrtle Beach homes are in buildings of five or more units (Census ACS 2020-2024). GSWSA’s standards give the shared stretch of a double residential connection to whoever owns the main it ties into, and multi-unit buildings on one service line get GSWSA’s Sewer Service Line Maintenance for a monthly fee. Check the association’s documents.

Sewer line repair vs replacement vs trenchless cost

Option	Fits when the camera shows	Digging	Typical cost drivers
Cleaning only	Roots, grease or sand in pipe that is otherwise sound	None	Cleanout access, root mass, a camera check afterward
Spot repair	One bad section: a crack, offset joint or short belly	One pit	Depth, groundwater in the pit, what sits on top, permit
Lining (CIPP)	Cracks or root entry in pipe that still holds its shape	Little or none	Length, cleaning before lining, access at each end
Pipe bursting	Broken pipe on a route a new HDPE pipe can follow	A pit at each end	Length, pit depth, nearby utilities
Open-trench replacement	Collapse, a deep belly or the wrong slope	The whole run	Depth, dewatering, stone bedding, restoration, cleanouts

A liner follows the old pipe, so it generally cannot correct a belly. See trenchless sewer repair for when lining or bursting works, and sewer line repair in Myrtle Beach for spot repairs.

Who pays for sewer line repair: the utility or the owner?

It depends on whose name is on your water and sewer bill. In GSWSA areas the owner generally pays for the pipe from the property-line connection to the house and GSWSA for its lateral and main; in Murrells Inlet, GCWSD makes owners responsible for the sewer from the home to the property line.

GSWSA’s split is inferred from its standards, so confirm it for your lot, and the cities of Myrtle Beach, North Myrtle Beach, Conway and Loris set their own rules; see who is responsible for sewer line repair.

On a backup, call the utility first. GSWSA’s rule is “Call GSWSA before you call your plumber”: it investigates at any hour at no charge, at (843) 234-8460 or (843) 443-8200 after hours, and fixes problems on its side. In Murrells Inlet, call GCWSD at (843) 546-8408 after hours; in the cities, call the number on your bill.

Does insurance or a utility plan cover sewer line repair?

Homeowners insurance usually does not pay to fix a worn sewer line, and backup damage generally needs an endorsement. GSWSA customers can enroll in its optional Service Line Maintenance plan instead: $2.85 a month for water and sewer on the first unit, covering lines from the right-of-way to the outside of the building.

GSWSA’s plan: sewer only is $2.60. It also pays for damage from a sewer backup in those lines, in an amount a GSWSA-selected adjuster sets before repairs. If the charge is not on your bill, you are not enrolled; call (843) 443-8202.
GCWSD (Murrells Inlet): a similar program; ask for current prices. Members who call a plumber before GCWSD pay that bill themselves.
Homeowners policies: the Insurance Information Institute (undated) says sewer backups are “not covered under a typical homeowners insurance policy” and that the coverage must be bought as a separate product or endorsement, “usually at a nominal cost.” The NAIC (updated Oct. 25, 2025) lists sewer backup among common optional add-ons. For the pipe itself, GCWSD warns that “Most homeowners insurance policies do not cover the cost of repairs.”

See sewer line insurance in Myrtle Beach for the options.

How pipe material and age change the cost

Older pipe tends to need bigger fixes and costs more to inspect: Angi’s camera guide (updated July 9, 2026) lists $175 to $300 for PVC, $250 to $400 for cast iron, $300 to $500 for clay and $400 to $800 for Orangeburg fiber pipe.

Lifespan claims conflict. For cast iron, This Old House (April 10, 2026) says 75 to 100 years, InterNACHI’s chart (undated) 50 to 60 below ground and a city utility in San Luis Obispo, California (undated), 30 to 50. For PVC, This Old House says over 100 years and InterNACHI 50 to 80; for clay, This Old House says up to 100 and San Luis Obispo 50 to 60. Of the sources we checked, only This Old House gives Orangeburg a figure: around 50 years.

Census figures (ACS 2020-2024) show 56.1% of Loris homes and 32.3% of Conway homes built before 1980, against 1.1% in Carolina Forest, so clay, cast iron and Orangeburg lines are likelier in the older towns. The pipe is usually a small share of the bill: This Old House (March 30, 2026) lists materials only at $120 to $320 for PVC and $800 to $3,000 for 40 feet of cast iron. See Orangeburg pipe and cast iron sewer pipe.

How to read a sewer line repair quote

Our process: a camera inspection, written options for each repair that will work, then permits and locates once you approve. A complete written quote lists:

Camera findings and video, with the distance to each defect
The method and why it fits
Length, depth and pipe spec, such as Schedule 40 PVC in GSWSA areas
Permit and inspection
SC811 locates and locating of your private line
Dewatering or stone bedding, if needed
Restoration of yard, driveway or sidewalk
Cleanouts added
Disposal of old pipe
Utility fees, as separate lines
What happens if opening the ground changes the job

Ask why if a quote recommends full replacement without video, or leaves out the permit or restoration. Every job is done by licensed plumbers and covered by liability insurance.

How to keep sewer line repair costs down

Camera first. The video shows whether cleaning, a spot repair or a new line is needed.
Spot repair a sound line. If one joint or crack has failed and the rest is sound, fixing that section usually costs less than replacing the run.
Add a cleanout while the line is open. Cutting one in during another repair usually costs less than a separate dig.
Ask about smoke-test findings. After smoke testing, GSWSA says it “will generally make all repairs found even on the customers service lateral.”
Join GSWSA’s plan early, if GSWSA serves you. At $2.85 a month for water and sewer, it covers the lines from the right-of-way to the building.
