Here is how we handle every drain cleaning project in Londonderry.
Our Londonderry plumber inspects the clogged drain — checking the cleanout access, running a camera for main line blockages, or assessing the drain type and flow to determine whether snaking or hydro-jetting is the appropriate approach.
We clear the blockage using the appropriate method — a drain snake for localized clogs, or high-pressure hydro-jetting for grease buildup, scale, or root intrusion in main lines.
Magnet Plumbing verifies that all drains are flowing freely at your Londonderry, NH property after clearing — running extended flow tests and checking downstream connections to confirm the blockage is completely eliminated.
Our Londonderry plumber explains what caused the blockage and recommends specific prevention measures — whether that is a grease trap for the kitchen, a hair catcher for the bathroom, or annual hydro-jetting for the main sewer line.
Common questions about drain cleaning in Londonderry.
Most Londonderry homeowners benefit from professional drain cleaning every 1 to 2 years as preventive maintenance. Kitchen drains in households that cook frequently may need annual service. Homes with large trees near the sewer line should have the main line inspected and cleared annually to prevent root buildup from causing backups.
Chemical drain cleaners are generally not recommended for Londonderry homes with older plumbing. The caustic chemicals can accelerate corrosion in metal pipes and degrade older PVC joints over time. They also rarely clear blockages completely and can make the problem worse by causing debris to compact. Professional drain cleaning by Magnet Plumbing is safer and more effective.
Drain snaking uses a rotating cable to break through or pull out blockages. It is effective for hair clogs and localized obstructions but leaves residue on pipe walls. Hydro-jetting uses high-pressure water to scour the full pipe interior, removing grease, scale, and root intrusion completely. For main sewer lines and recurring clogs, hydro-jetting provides more thorough and longer-lasting results.
Drain cleaning in Londonderry typically costs $150 to $350 for standard drain snaking and $300 to $600 for hydro-jetting depending on the line size and length. Main sewer line cleaning costs more than individual fixture drains. Magnet Plumbing provides transparent pricing before starting any drain cleaning work in Londonderry.

"Once again Magnet Plumbing came to save the day. I manage a building of 49 units and we had a gas leak somewhere. The city shut the gas for the whole building. They showed up right away and got to work. They found the problem, fixed it, and were able to turn the gas back on so people could have dinner. Saul is amazing — right on time, very professional."
"Fixed a hidden leak behind the drywall without tearing apart the whole wall. Impressed with how precise they were and how quickly they found it."
"We noticed our water bill doubling month over month and could not find anything visible. These guys came out with the leak detection equipment and located a slab leak under the living room in about thirty minutes. The repair was minimally invasive — small access cut, patched afterward, and the bill is back to normal. Really impressed with the professionalism."
