We are the water heater and sewer experts of Santa Clara County offering free estimates, fair rates, and superior workmanship. Our team has been servicing the Bay Area for over 20 years. Our company is licensed, bonded, and insured. Our specialists are equipped, experienced, and provides a full range of services. We guarantee our work and can beat any quote by 10%.

"Chandlers Plumbing responded to my 'cry for help' during a weekend emergency; and not only showed up on time, with a courteous and knowledgeable crew; they also gave me a VERY reasonable fixed price quote - 75% under those others (that I suspect were price-gauging my "elderly lady in an emergency" status). They were able to start the work right away, and made sure I approved of the work before closing the trench the same day. They left the area like it looked before, with the mulch intact and not mixed up with soil - and my problem is fixed for the next 40 years or so. Definitely recommend !"

"So far so good. Snaking of kitchen sink with very old pipes. Hopefully snake did not poke pipes. Only time will tell. Keeping fingers crossed. They did a good job explaining and triple checked for leaks before they left. Of course they tried to upsell and gave us a metal trap they did not quote us upfront for. We would have chosen it over plastic, but price difference would need to be cleared upfront. That's the only negative. Otherwise, thus far we are very happy with the result. Thank you for coming on such short notice and on time! Super appreciated. 4.5-5 stars."

FAQs for drain clog or blockage clearing projects in San Mateo, CA

Snaking a simple clog near a tub, toilet, or sink often takes about five minutes. Deeper blockages along the main line can stretch the job to a few hours because the pro must feed extra cable and may need a camera to confirm the pipe is clear. Either way, specialized tools help pros work quickly and keep your drains running for the long haul.

Aggressive snaking can scratch pipes, push debris deeper, or even crack older lines. That risk is low with an experienced plumber who matches the cable size to the pipe and eases the snake through bends instead of forcing it. If you’re unsure of your technique—or your pipes are already fragile—calling a licensed pro is the safest, and often cheapest, move.

Start with simple barriers: mesh screens on every tub, shower, and sink keep hair, food bits, and jewelry out of the pipes. Skip harsh chemicals; a monthly flush with hot (not boiling) water clears light buildup without damaging plastic lines. Finally, practice smart disposal—no grease, wipes, or kitty litter down the drain—and schedule routine cleanings if you have older plumbing.

Roto‑Rooter typically charges a flat $160 to $450 for standard snaking, which may include a quick sewer inspection and basic clean‑out. Exact pricing depends on the clog’s location and complexity. Repairs or part replacements fall outside that flat fee, so ask for a line‑item estimate if your tech spots broken pipe sections or recommends additional work.

Most liquid cleaners rely on caustic chemicals that eat through hair and grime—but they also erode metal and even some plastics over time. Repeated use strips protective pipe coatings and can leave you with leaks or premature failures. If hot water or a plunger doesn’t help, call a plumber for mechanical removal instead of pouring more chemicals down the line.
