Hydro jetting uses streams of water at 3,500 to 4,000 psi to scour pipe walls clean instead of simply punching a hole through a clog. In Portland's pre-1950 housing stock found on Munjoy Hill and in the East End, cast iron and clay lines often carry decades of grease and mineral scale that cable machines leave behind. The method restores full diameter flow without chemicals that could harm Casco Bay.
Winter freezes in Cumberland County push more calls after pipes contract and joints shift under snow load. Jetting reaches root intrusions common where Eastern Promenade maples send roots toward sewer laterals. Operators adjust pressure on the fly when they encounter the thinner walls of 1920s terra cotta that still serve many Parkside homes.
Unlike snaking, hydro jetting removes the film that lets grease reattach quickly. It works on 3-inch kitchen lines in Old Port restaurants and 6-inch mains serving multi-family buildings in Deering. Crews always camera-inspect before and after because a single cracked joint can turn a routine job into an excavation in Westbrook or South Portland.
Technician insight
In Portland, the thing that catches most people out with Hydro Jetting is how many East End and Munjoy Hill homes still have 100-year-old clay laterals that can fracture if the operator does not start at low pressure and watch the camera the whole time.
East End Lateral After Heavy Snow
A Parkside homeowner called after slow drains returned following January thaw. Camera showed roots and compacted grease 60 feet out in a clay lateral. We jetted at graduated pressure, removed the buildup, and verified full flow with a final inspection. The line has stayed clear through the following winter.

How it works
- 1
Camera Inspection
We run a camera through the line to locate the clog and note pipe material and condition before any water is introduced.
- 2
Access Point Setup
Technicians select the safest entry point, often a cleanout in the basement or yard, to avoid damaging older Portland fixtures.
- 3
Controlled Jetting Pass
High-pressure water is applied in measured passes, starting low and increasing to cut through roots or grease without stressing fragile clay sections.
- 4
Final Verification
A second camera run confirms the pipe is clear and free of damage before we restore access points and clean the work area.
Pricing
Most hydro jetting jobs in Portland fall between a few hundred and low four figures depending on access and pipe condition.
