Store-bought drain cleaners dissolve soap and light grease. They do nothing for root intrusion, grease buildup 40 feet in, or a collapsed pipe segment. Masters Plumbing Service's Drain Cleaning team in Woonsocket arrives with professional-grade augers and hydro-jetting units that actually resolve the blockage.

Retail drain products and inexperienced plumbers share one problem: they treat the symptom, not the cause. Our approach combines the right equipment with the right diagnostic process.
Our truck-mounted hydro-jetting units propel water at up to 4,000 PSI through a rotating nozzle that scours pipe walls clean — removing grease buildup, scale, and soft root intrusions in a single pass. Unlike augers, jetting leaves the pipe interior clean rather than just piercing a hole through the clog.
A camera inspection saves you money by showing us exactly what we're dealing with. It also protects you from paying to clear a blockage that's actually hiding a structural pipe failure that will recur immediately.
Whether it's a backed-up bathroom sink or a full house sewer drain stoppage, our team carries the right nozzle sizes and cable diameters for the specific pipe we're clearing.
Our written service report notes the blockage type, location, method used, and any structural observations from the camera run. You walk away knowing the state of your drain system, not just that the water is flowing again.
From a slow bathroom sink to a full main-line stoppage affecting every fixture in the house, our drain techs in Woonsocket, RI have the equipment and training to clear it.
Kitchen drains accumulate FOG — fats, oils, and grease — that solidifies on pipe walls and progressively narrows the line. We use a combination of a cable auger to break the initial plug and a hot-water hydro-jet pass to scour the residual grease film. For commercial kitchens, we also service grease interceptors and document cleaning for inspection records.
Hair and soap scum are the most common bathroom drain blockages. They bond to the pipe walls inside the p-trap and in the drain arm, forming a mat that progressively constricts flow. Our techs remove the drain cover, clear the p-trap obstruction with a hand snake or drum auger, and flush the line.
When multiple fixtures are draining slowly or backing up simultaneously, the blockage is typically in the main sewer line — the 4" or 6" pipe that carries all household waste to the municipal main or septic system. We access the main line through the cleanout, run a CCTV camera to identify the obstruction type, then clear with a sectional cable machine or hydro-jetter depending on what we find.
Basement floor drains and laundry room drains often go years without cleaning and can develop sediment, lint, and mineral scale blockages. We clear these drains with an electric snake and flush thoroughly to confirm full flow before closing out the job.
A preventive jetting program documented over multiple visits gives you both clean pipes and a camera record of pipe condition over time — useful for catching structural deterioration before it causes an emergency.
Our inspection reports are accepted by real estate attorneys, home buyers, and insurers as documented evidence of drain system condition. If you're buying or selling a home in Woonsocket, a pre-purchase drain scope is one of the best $300 you can spend.
We don't show up and start snaking blind. Our approach uses a camera-first diagnostic protocol to confirm what we're clearing before selecting the method.
Tell our dispatcher which fixtures are affected — one slow drain vs. multiple backed-up fixtures tells us whether we're likely dealing with a localized clog or a main line blockage. We schedule same-day when slots are available.
The camera also gives us the distance to the blockage and confirms the pipe diameter — both factors in selecting the right clearing method and nozzle size.
If the camera reveals a structural problem that will require repair rather than just clearing, we tell you that now rather than letting you pay for a clearing that won't last.
After clearing, we run the camera a second time to confirm the pipe is open to full diameter. You see the before-and-after footage. We provide a written service summary and our drain clearing warranty.

Called about a kitchen drain that three other plumbers had snaked without long-term success. Masters Plumbing Service ran a camera first and found grease buildup 28 feet in, past where any hand snake reaches. Hydro-jetted it, re-scoped to confirm clean, and the drain has run perfectly in the months since.
All three bathrooms drained slowly and the lowest floor toilet gurgled every time an upstairs fixture ran — classic main line partial blockage. Masters Plumbing Service's tech accessed the cleanout, ran the camera, and found root intrusion at a clay tile joint about 40 feet from the house. He cut the roots with the root cutter attachment and re-scoped to confirm clear flow. Also noted a joint offset at 68 feet that we'll need to line eventually — good to know before it becomes a full backup.
Had a pre-purchase drain scope done on a home we were buying. Masters Plumbing Service's tech ran every accessible drain and the main sewer line with the camera, gave us a written report with timestamps and footage. Found a small bellied section in the main line that the seller agreed to repair before closing. Worth every penny for the negotiating power alone.
