How much does drain cleaning cost in Massachusetts?
A standard residential drain cleaning typically runs $150–$350 in the Greater Boston area. Main sewer line clearing is usually $300–$650, and hydro jetting is $450–$900 depending on length and severity. We give you a written, flat-rate price before any work starts.
Will drain cleaning damage my pipes?
No — when done with the right equipment for your pipe type. We always inspect first and match the method (cabling, hydro jetting, or descaling) to the pipe material and condition.
Why do my drains keep clogging?
Recurring clogs almost always point to a deeper issue: grease buildup, scale on cast iron walls, tree-root intrusion, or a partial collapse. A camera inspection identifies the root cause so we fix it once instead of clearing it monthly.
Do you guarantee the work?
Yes. We stand behind every drain cleaning. If the same line clogs again under normal use within our service window, we come back at no charge.

Learn more about commercial drain cleaning →Can you work after hours?
Yes. We schedule commercial work around your business — including nights, weekends, and emergencies.
Sewer Line Cleaning
Learn more about sewer line cleaning →Do you inspect the line after cleaning?
Yes — we use video inspection to confirm the line is clear and identify any underlying issues.
How much does sewer line cleaning cost in Massachusetts?
Main sewer line cabling typically runs $325–$650 in Greater Boston. Hydro jetting a residential main is $450–$900. Heavy root infestation or a long line can push it higher — we always quote a flat price upfront.
How do I know if it's the main sewer line?
Telltale signs: multiple fixtures back up at once, the toilet bubbles when the washer drains, sewage shows up in the basement floor drain, or you smell sewer gas in the lowest level. Any of those — call us.
Will tree roots come back after cleaning?
Cabling clears roots but doesn't kill them, so they typically grow back in 12–24 months. Hydro jetting is more thorough. For long-term fixes we'll recommend annual maintenance, root-foaming, or a spot repair.
Main Sewer Line Cleaning
Learn more about main sewer line cleaning →What causes main sewer line clogs?
Tree roots, grease buildup, collapsed pipe sections, and foreign objects are the most common causes.
Clogged Drain Repair
Learn more about clogged drain repair →Why does my drain keep clogging?
Recurring clogs usually indicate buildup, pipe damage, or a partial blockage further down the line. A camera inspection will tell us exactly what's happening.
Toilet Drain Cleaning
Learn more about toilet drain cleaning →Should I keep flushing if my toilet is slow?
No — stop flushing and call us. Repeated flushing can cause overflows and damage.
Sink Drain Cleaning
Learn more about sink drain cleaning →Are chemical drain cleaners safe?
We don't recommend them — they can damage pipes and rarely solve the underlying issue. Mechanical cleaning is safer and more effective.
Floor Drain Cleaning
Learn more about floor drain cleaning →Why does my basement floor drain back up?
Usually it's a clog further down the main sewer line. Camera inspection will pinpoint the exact location.
Storm Drain Cleaning
Learn more about storm drain cleaning →How often should storm drains be cleaned?
At least once a year, ideally before fall and spring rain seasons.
Grease Trap Cleaning
Learn more about grease trap cleaning →How often should a grease trap be cleaned?
There is no single schedule that fits every kitchen: service frequency and paperwork requirements are set locally, so confirm yours with your local sewer authority or board of health. In practice many Greater Boston restaurants end up on a 30–90 day cycle depending on trap size, volume, and menu, and we can measure how fast your trap fills to help you set an interval.
How much does grease trap cleaning cost in Boston?
A standard under-sink grease trap (20–50 gallon) pump-and-clean typically runs $175–$375. Larger in-ground interceptors (500–2,000 gallon) run $325–$750+ depending on capacity and access. Hydro jetting the grease line downstream is $300–$600. All flat-priced in writing before any work begins.
What's the difference between grease trap cleaning and pumping?
Pumping removes the liquid grease and waste. A full cleaning also scrapes the walls and baffles, washes down the trap, and inspects the inlet/outlet tees so the trap actually works for the next interval. We always do both — a trap that is only pumped keeps its coated walls and any damaged tees.
Do you handle the grease waste disposal manifest?
Yes. We haul the waste off-site and provide you a manifest for every pump-out. Ask your local sewer authority or board of health which records they require you to keep.
Can you work after hours so we don't lose service?
Yes. Most of our restaurant clients are on a late-night or early-morning schedule so the dining room never sees us. We work overnights, weekends, and around your prep schedule.
My grease line keeps clogging — what's the fix?
If the line downstream of the trap is clogging on a regular cycle, the trap is either undersized, overdue, or the line itself is coated in FOG. The right answer is almost always a hydro jet of the entire grease line plus a tightened pumping schedule. We'll camera the line, jet it once, and get you on a maintenance interval that keeps it clear.
Sewer Camera Inspection & Video Pipe Inspection
Learn more about sewer camera inspection & video pipe inspection →What's the difference between a sewer camera inspection and a video pipe inspection?
Same thing. 'Sewer camera inspection,' 'video pipe inspection,' 'sewer scope,' 'drain camera' — all describe running a waterproof HD camera through a pipe so you can see the inside. We use the same equipment for residential laterals, commercial drains, and pre-purchase home inspections.
How much does a sewer camera inspection cost in Boston?
A standalone HD sewer camera inspection in Greater Boston runs $295–$495 and includes line locate, depth marking, and inspection footage. We often discount it when bundled with cleaning. Branch line / fixture push-camera work is $195–$345.
What does a sewer camera show?
It shows the interior condition of the pipe — cracks, root intrusion, bellies (sags), separated joints, scale buildup, foreign objects, and the exact pipe material (cast iron, clay, PVC, Orangeburg). With a sonde locator we also mark the exact location and depth of any defect above ground.
Do I need a camera inspection before buying a home?
Yes if the home is older than 25 years, has any large trees near the sewer line, or is in a neighborhood with known clay or Orangeburg pipe (most of older Boston, Dorchester, Brookline, Cambridge, and the inner suburbs). Hidden sewer line damage is one of the most expensive surprises in a home purchase — a $295 inspection has saved many of our clients $15,000+ repair bills.
Do you provide a video of the inspection?
Yes — we share the footage and a written summary so you have a complete record. Real estate clients use it for negotiation; property managers use it for capital planning; insurance clients use it for claims.
Can you locate the depth and exact spot of a problem?
Yes. The camera has a 512 Hz sonde transmitter built into the head. We bring a locator above ground, walk the line, and mark the exact location and depth of any defect with paint. No guessing where to dig.
High-Pressure Water Jetting
Learn more about high-pressure water jetting →Is hydro jetting safe for older pipes?
Yes, when done by experienced technicians who adjust pressure to the pipe condition. We always inspect before jetting.
Hydro jetting vs snaking — which is better?
Snaking (cabling) punches a hole through a clog quickly and is great for soft blockages. Hydro jetting scours the entire pipe wall — clearing grease, scale, and roots — and leaves the line near-original-diameter clean. For grease lines, restaurants, and recurring clogs, jetting is the right call. For a one-off soft clog, cabling is faster and cheaper.
How much does hydro jetting cost in Massachusetts?
Residential main line hydro jetting typically runs $450–$900 in Greater Boston. Commercial grease lines and longer runs are quoted on-site. Always includes pre-camera inspection and post-camera verification.
Can hydro jetting damage pipes?
Not when done correctly. We always camera first, identify the pipe material and condition, and adjust pressure accordingly. We won't jet a pipe that's structurally compromised.
Pipe Descaling
Learn more about pipe descaling →Does descaling damage the pipe?
No — descaling removes buildup, not pipe material. It restores the original interior diameter.
Preventative Maintenance
Learn more about preventative maintenance →How often should drains be maintained?
It depends on use — restaurants and commercial kitchens often need monthly service, while homes typically benefit from annual main line cleaning.
Sewer Rodding
Learn more about sewer rodding →What's the difference between sewer rodding and snaking?
They're the same thing — different regions use different words. Both refer to running a powered cable (the 'rod') with a cutting or auger head through the pipe to clear a blockage. Rodding is the older term used by drain companies; snaking is more common in residential conversation.
Rodding vs hydro jetting — which is right for me?
Rodding punches through a clog and cuts roots; it's fast, cheap, and great for emergency clearing. Hydro jetting scours the entire pipe wall and removes grease, scale, and soft root mats; it's the right tool for grease lines, restaurants, recurring clogs, and any pipe that needs to be restored to true diameter. We diagnose first and recommend the method that solves the cause — not just the symptom.
How much does sewer rodding cost in Massachusetts?
Main sewer line rodding typically runs $325–$650 in Greater Boston through an accessible cleanout. We give you a flat written price before any work begins.
Will rodding fix tree roots permanently?
Rodding cuts roots and restores flow, but the roots regrow — typically in 12–24 months. For long-term control we recommend an annual maintenance plan or pairing rodding with hydro jetting and root-foaming.
Catch Basin Cleaning
Learn more about catch basin cleaning →How often should catch basins be cleaned?
Most commercial properties in Massachusetts clean catch basins once or twice a year — typically in spring after snowmelt and in fall after leaf-drop. Sites with heavy tree cover, parking-lot traffic, or DEP/MS4 stormwater requirements often need quarterly service.
What does catch basin cleaning include?
We vacuum out accumulated sediment, leaves, and debris from the basin sump, jet the outlet pipe to confirm clear flow, and document the work with before/after notes for your records.
Do you provide documentation for MS4 compliance?
Yes. We provide written service records showing what was cleaned, when, and the condition of the basin — which property managers use for stormwater permit compliance.
Can you handle large commercial properties on a schedule?
Yes. We set up recurring schedules for property managers across Greater Boston — most clients are on a spring/fall cadence, with optional storm-season add-ons.
Sewer Scope Inspection
Learn more about sewer scope inspection →What is a sewer scope inspection?
A sewer scope is a video inspection of the main sewer line that runs from your house to the street or septic tank. A waterproof HD camera on a flexible rod is fed through the line so you can see the inside of the pipe — cracks, root intrusion, bellies (sags), pipe material, and any blockages.
Why isn't a sewer scope part of a standard home inspection?
Standard home inspectors aren't trained or equipped for it and don't carry the equipment. The general inspector tests fixtures and visible plumbing, but the buried sewer line — often the most expensive thing to repair in a house — is invisible to them. That's why a separate sewer scope is recommended on any home older than 25 years or with mature trees near the line.
How much does a sewer scope inspection cost in Boston?
A standalone HD sewer scope in Greater Boston runs $295–$495 and includes the inspection footage, written summary, and depth/location marking of any defects we find. That's a tiny fraction of what a sewer line repair costs, which is why buyers, sellers, and agents request them.
Should I get a sewer scope before buying an older home?
Yes — especially on any home built before 1980, any home with large trees near the lateral, and any property with a clay, cast iron, or Orangeburg sewer pipe. Hidden sewer line damage is one of the most expensive surprises in a home purchase, and a scope catches it before you're the owner.
What do you do if you find a problem?
We document the defect on camera, mark its exact location and depth above ground with a sonde locator, and give you a written summary so you (and your agent) can negotiate with the seller. We never pressure you toward repair work — the inspection is the deliverable.
