A slow drain is a warning. By the time it's a complete blockage, you've lost use of your kitchen, bathroom, or laundry room entirely. Masters Plumbing Service's Greenfield drain crew uses professional-grade augers, hydro-jetters, and CCTV cameras to resolve blockages at their source.

Retail drain products treat symptoms. Our approach identifies what type of blockage you're dealing with โ because the method that clears a grease plug efficiently is different from the one that handles root intrusion.
Before recommending any clearing method, we run a push-rod camera into the line to visually confirm blockage type, location, and pipe condition. Grease 30 feet in looks different from a root ball at a joint โ and each needs a different response.
Hydro-jetting is the only method that restores full pipe diameter. A cable clears the blockage; a jetter removes the material that caused the blockage from the pipe wall entirely.
We clear kitchen drains, bathroom sink and shower drains, floor drains, laundry drains, and 4โ6 inch main sewer lines. Our nozzle set and cable sizes scale from a 1.5-inch drain arm to a 6-inch commercial main.
Before-and-after camera footage is available for main line work. Insurance claims and real estate disclosures often require this documentation โ we provide it as a standard part of camera-scope jobs.
Not every blocked drain is the same problem. Here's how our team approaches each type โ with the specific tools and techniques that actually resolve it.
Kitchen drains accumulate FOG โ fats, oils, and grease โ that solidifies on pipe walls and progressively narrows the line over months and years. We use a combination of a cable auger to break the initial plug and a hot-water hydro-jet pass to scour residual grease film from the pipe walls. For commercial kitchens we also service grease interceptors and document the cleaning for health code records.

Chronic slow bathroom drains often point to a partially closed p-trap, a buildup on the overflow plate mechanism, or a drain arm pitched incorrectly. We clear the immediate clog and identify if a mechanical fix is needed to prevent fast recurrence.
Root intrusion at pipe joints is the leading cause of main sewer blockages in homes over 20 years old. Our electric root cutter removes the root mass; we re-scope after clearing to confirm the line is open to full diameter before pulling equipment.
Basement floor drains and laundry room drains often go years without service and develop sediment, lint, and mineral scale blockages. We clear with an electric snake and flush thoroughly. Floor drain traps can also dry out and allow sewer gas into the structure โ we re-water the trap and can install a trap primer if the drain is prone to drying in Greenfield's climate.
Restaurants, multi-family buildings, and homes with chronic grease or root problems benefit from scheduled hydro-jet maintenance on a 12โ24 month cycle. We map the drain system, document baseline camera footage, jet the lines, and re-scope to confirm clean pipe walls โ preventing emergency backups rather than reacting to them.
A standalone camera inspection documents drain system condition for pre-purchase due diligence, insurance claims, or understanding why a drain is performing poorly before committing to a repair approach. We run the camera, record footage with distance markers, and provide a written scope report noting blockage types, root intrusion points, joint offsets, and any visible structural defects.
Here's exactly how a Masters Plumbing Service drain call plays out in Greenfield, NH.
Your description lets us arrive with the right tools. One slow drain vs. multiple backed-up fixtures is a different setup.
Camera footage confirms distance to the blockage and pipe diameter โ both critical for selecting the right clearing method and nozzle size.
If the camera reveals a structural problem requiring repair rather than just clearing, we tell you now rather than charging for a clearing that won't last.
After clearing, we run the camera again to confirm the pipe is open to full diameter. You get a written service summary and our drain clearing warranty before we leave.

Called about a kitchen drain three other plumbers had snaked without lasting results. Masters Plumbing Service ran a camera first and found grease buildup 28 feet in โ past where any hand snake reaches. Hydro-jetted it, re-scoped to confirm clean, and the drain has run perfectly ever since.
Main line backed up on a Sunday. Masters Plumbing Service came within 2 hours, camera found a 3-inch grease plug combined with roots at a joint, cleared both with cable and jetter, and sent me the scope video. Exactly the transparency I wanted.
