We rebuild the pipe under your house without taking the house apart.
Reuter & Knapp Trenchless is a small civil-trades shop on Niagara Street in Black Rock. We line, burst, and replace the century-old sanitary laterals, storm leaders, and lead service lines under pre-1940 houses on Buffalo's West Side, Elmwood Village, North Park, Allentown, Riverside, and the South Towns. Where the geometry permits, we don't dig. Where it doesn't, we say so before we quote.
The work, plainly stated
Most of Buffalo's sanitary laterals were laid in terra-cotta between 1895 and 1935, and most of them are now ninety-plus years old.
They've absorbed root intrusion, ground heave from forty Buffalo winters' frost cycles, and decades of cast-iron coupling drift. Some are cracked. Some are belly-sagged. Some have been patched four times by four different crews and are doing the structural work of a damp newspaper. The customer almost never owns the asset until something has already gone wrong with it.
We are a trenchless crew. That means: when we can, we restore the existing pipe — or pull a new one through its path — without trenching across your front yard, your driveway, or the asphalt of a city street under a Buffalo Sewer Authority permit1. We pressure-invert a felt-and-resin sleeve into the host pipe and cure it in place; we crack the host pipe and pull a new HDPE line through the same bore on a hydraulic winch; we cut a single 4′×4′ access pit and replace the bad joint without disturbing the rest. The house remains a house, the lawn remains a lawn, and the trip to the basement remains a trip to the basement.
Where trenchless can't be the answer — a fully collapsed pipe, an offset that exceeds the bursting head's tolerance, a foundation entry whose host wall is unreliable — we say so before we quote, and we explain what an open-cut would look like instead. We are willing to lose the job. We aren't willing to lose the customer's confidence two years on, when the lining we shouldn't have installed begins to fail and they have to pay twice.
This site is built like a public-works project archive. Every method we use is documented under Methods. Every failure mode we read in the camera survey is documented under Failure Atlas. Every job we close is filed under Casebook. The dye-test rules and lateral-jurisdiction questions that govern who pays for what are under Records. If you read no other page on this site, read that one.
What we do, in five categories
Methods
Each method below has its own page with diagrams, a real photograph, the toolchain, the standards we work to, and the conditions under which we'd recommend something else.
CIPP lining (cured-in-place)
A felt-and-resin sleeve is inverted by air or water into the host pipe and cured in place to form a structural liner. Best for hairline-cracked, root-infiltrated, or joint-offset clay laterals where the host bore is still continuous.
RKT-MTH-02Pipe bursting (HDPE replacement)
A pneumatic or hydraulic bursting head is winched through the host pipe, fragmenting it outward and pulling a new HDPE line behind. Best for fully failed, undersized, or material-mismatched lines where you need a brand-new pipe.
RKT-MTH-03Spot repair & cleanout installation
A single 4′×4′ access pit at the failure point: replace the bad joint, install a code-compliant exterior cleanout, and restore. The right answer when one section is bad and the rest of the run is sound.
RKT-MTH-04Lateral locating & CCTV survey
PACP-coded camera inspection from the cleanout to the main, with sonde-traced location, depth, and material at every fitting. The diagnosis that determines every other recommendation we make.
RKT-MTH-05Lead service-line replacement
Full replacement of the ¾-in. or 1-in. lead service from main to meter, by directional bore or pipe-burst, with NYSDOH-compliant flush and post-replacement water-quality verification. Coordinated with Buffalo Water and the LCRR inventory.

The Failure Atlas
Every CCTV survey we run is coded against the NASSCO Pipeline Assessment Certification Program3. The atlas below is our pictorial field guide to the five morphologies we read most often under pre-1940 Buffalo houses. Each entry is a plate: a labeled cross-section diagram, a real-world photograph, the diagnostic key, and what we'd recommend.
Plate A · Root intrusion at the bell-and-spigot joint
RKT-MOR-A · Sample- A, B
- Vitrified-clay pipe sections, 6" nominal ID, original 1895–1935 install
- C
- Lateral root mass — typically silver maple, Norway maple, or American elm
- D
- Circumferential hairline crack at the spigot end, ≤ 0.5 mm
- E
- Original jute-and-bituminous joint fill, deteriorated
Root intrusion
The most common failure mode under Buffalo's tree-lined streets. Root mass enters at the bell joint and progressively occludes flow.
RKT-MOR-BJoint offset
Differential settlement under the foundation step or the curb has shifted one bell relative to the next.
RKT-MOR-CBelly / sag
A vertical low spot where standing water collects between flushes. Symptom: recurring slow drains in a basement-floor cleanout.
RKT-MOR-DLongitudinal crack
A crack running along the pipe's axis, usually under traffic load on a driveway or under a sidewalk slab.
RKT-MOR-ETotal collapse
The pipe wall has failed and a section of bore is missing. Trenchless rehabilitation is no longer an option for that segment.

From the Casebook
Every closed job is filed as a numbered dossier with a CCTV survey, the diagnosis, the method we used, the cost breakdown, and a 12-month follow-up note. We publish a selection. Names are reduced to initials; addresses are reduced to the cross-streets.
Elmwood Village · CIPP, 4× root masses
42-ft 6-in. clay lateral, four root masses keyed to a single mature silver maple. Lined in eight hours. $7,440 turnkey.
RKT-DOS-141 · 2024-11Allentown · pipe burst, 4"→6" upsize
Originally 4-in. cast iron, three offset belled joints and a longitudinal crack at the curb stop. Burst to 6-in. HDPE in a day. $11,200.
RKT-DOS-203 · 2025-12North Park · lead service-line replacement
¾-in. lead service from 1922, replaced with 1-in. K-copper. Coordinated with Buffalo Water under the LCRR inventory program. $6,200, partially reimbursed.
Why the records page matters
The lateral under your house is yours, even where it runs under the city's street.
Under Buffalo Sewer Authority rules, the homeowner is responsible for the sanitary lateral from the building foundation to the connection at the city's main — including the portion that runs beneath the public sidewalk and street.4 The Buffalo Water Board takes the same position on the ¾-in. or 1-in. service line.5 If a sinkhole opens over your lateral on Forest Avenue or your service blows under the curb on Bidwell, the bill is yours, the permit is yours, and the restoration of the street cut is also yours.
This is a real legal regime — not a marketing point. McLaren v Caldwell (1884) established that local infrastructure regulation is squarely within provincial-or-state jurisdiction;6 Buffalo's sewer-use regulations are the descendant of that principle, and Buffalo's Common Council has updated them in the intervening 142 years without disturbing the homeowner-owns-the-lateral premise. Our Records page documents the rules, the dye-test procedure the BSA uses to determine which side of the connection a failure sits on, the LCRR-driven lead-service-line inventory deadline, and the insurance options Buffalo Water has offered since 2018. If you live in a pre-1940 Buffalo house, this is the page to read first.
Where we work
Neighborhoods
We are based on Niagara Street between Hertel and Forest, a six-minute drive from Black Rock and ten minutes from the West Side. Our day-to-day service area is the pre-1940 housing stock north of the Skyway and south of the Tonawanda line, in zip codes 14201 through 14216, plus contract work in Hamburg and Orchard Park.
Elmwood Village
14222. Mature silver-maple canopy, brick driveways, 1900–1925 housing. The single highest density of root-intrusion cases on our books.
North Park
14216. 1915–1935 housing on Hertel and Parkside. High concentration of remaining lead service lines, on track for replacement under LCRR.
Black Rock & Riverside
14207. Our home turf. Mixed industrial and residential, oldest housing stock, frequent CIPP candidates.
The crew
Eight people, two trucks, one shop
No call center. No dispatcher in another state. The person who picks up the phone at 7:14 a.m. is one of three people, all of whom have been in a Buffalo basement at three in the morning. Read the bios — every one of them is signed, and every claim has a year on it.
Al Reuter
Master plumber, Local 22. Founded the shop after eighteen years at Cellino. PACP/MACP/LACP certified. Runs the inversion rig.
Partner · 2014Marie Knapp
CIPP foreman, lead estimator, BSA liaison. Civil engineer (UB '11). Runs the casebook.
Lead operator · 2019Dani Okonkwo
Pipe-bursting specialist. Locator. Master diver-cert (transferable patience for inversion-cure timing).
How to begin
Three ways to get a number on the page.
If you have a backed-up basement and standing water now, call the dispatch line. If you have a slow drain that has been getting slower for a month, request an estimate online and we'll book a CCTV survey. If you are buying a 1908 Allentown duplex and want to know whether you'll have to rebuild the lateral inside three years, request the same survey and we'll write a report your inspector can read.
- Call: (716) 783-4488 · 7 a.m. – 5 p.m. weekdays · 24/7 emergency
- Email: dispatch@reuterknapp.example · 24-hour response
