Quick Answer
Real hydro jetting needs a truck-mounted pump (4,000+ PSI, 18+ GPM), camera inspection before and after, nozzle selection matched to the job, and a technician willing to tune pressure to the pipe. Ask for the PSI rating, ask if they camera first, ask what nozzles they have on the truck, and ask whether they jet cast iron at full pressure (they shouldn't). The answers separate a real jetting outfit from one that sends a portable jetter and hopes for the best.

Search "hydro jetting near me" in Boston and you'll get dozens of companies that claim to do it. Some of them actually do. Others own a portable jetter, write the keyword on their site, and figure they'll send out the cable machine when they get to your house. Five questions to ask before you book.
1. What's the PSI and GPM rating on your jetter?
Real residential hydro jetting needs 4,000+ PSI at 18+ GPM. That's a truck-mounted pump, not a portable. Below those numbers you're not scouring the pipe wall — you're just wetting the clog. If they hem and haw on this question or say "we'll bring whatever's needed," they probably own one undersized machine.
2. Will you camera the line before jetting?
The right answer is yes, every time. A camera inspection tells the technician three things: pipe material (cast iron vs PVC vs clay vs Orangeburg), pipe condition (intact, scaled, cracked, separated), and what's actually in the line (grease, roots, scale, foreign objects). Jetting blind is how you turn a $700 cleaning into a $7,000 spot repair. We camera first, every time.
3. What nozzles do you have on the truck?
Different jobs need different nozzles:
- Penetrating nozzles — punch through the clog
- Flusher nozzles — scour grease off the pipe wall
- Root-cutting nozzles — chew through soft root mats
- Chain knockers / mechanical descalers — for hardened scale on old cast iron (paired with jetting)
A truck with one nozzle is a truck doing one job badly.

4. Do you tune the pressure to the pipe condition?
Full commercial-grade pressure on a fragile cast iron line, or on Orangeburg, or on a clay lateral with separated joints, will cause damage. A real jetting operator backs the pressure off when the pipe needs it. Ask directly: "Would you jet a cracked Orangeburg lateral at full PSI?" The right answer is no.
5. Will you re-camera after jetting?
Pre-camera confirms the diagnosis. Post-camera confirms the result. Without the post-camera, you have no way to know if the line is actually clean or just temporarily flowing. We re-camera as part of every jetting job — it's how you know you're not going to be calling us back in three weeks.
What this should cost in Greater Boston
- Residential main line hydro jetting: $450–$900
- Commercial grease line: $600–$1,500 typical (quoted on-site)
- Pipe descaling + jet on scaled cast iron: quoted on-site
Quotes much below those ranges are a sign you're not getting a truck-mounted jetter or a pre-camera. Quotes much above are a sign someone's padding. The right answer is a flat written price before any work begins.
