Customers say: Super punctual

"The plumbing technicians came out as promised to assess the leak. They were both very courteous and kind and assessed the damage. I am giving three stars because they estimated the cost to be almost 250% higher than what the actual cost was to fix the issue. I am sure there are customers out there that would just accept any bid however, please get multiple beds for these projects, especially when working with this company as they will inflate the cost to take advantage of the situation. I ended up only paying for the $79 estimate."

"We needed a building cleanout installed as a requirement for our remodeling project. Cornelio was very thorough in investigating what were the requirements for the inspection. He installed a dual cleanout following all the requirements which will help us in case of any backups in the future. He was very transparent about the cost, and finished the installation on the following day. Highly recommend him for any plumbing issues."

"Isaac and team were incredible in getting a bunch of updating old and out-of-code plumbing work done on our tricky 100-year-old house. They took time to really dig in and assess the right game plan to make sure not only that all the plumbing and vents were done properly, but that they looked great given some would still be exposed / visible under our porch. The team was communicative and courteous. Our new plumbing is working like a charm. The tankless heater and smart shutoff are cranking. And everything passed on first inspection. The inspector even commented how clean and detailed it all looked. Would recommend SplashFix for any project, big or small."

"Me and my wife decided recently to get our kitchen remolded. After some time searching for the right guys to do the job we settled on RG Construction. Richard, who is the owner, is a great guy and super informative. He never left any question unanswered or left us uncertain about anything. His crew works quick, and they pay attention to the tiniest detail. They absolutely are worth every dollar and I would recommend RG Construction to any homeowner, and I for sure will be giving them a call back for any work I need done in the future. Me and my wife are absolutely in love with our remodel."

"Great experience with In & Out Plumbing. Jose was incredibly helpful and knowledgeable while providing maintenance service on our water heater—he took the time to explain everything and made sure it was running smoothly. Alec was also fantastic in helping get everything set up and coordinated. Professional, efficient, and easy to work with. Highly recommend!"

FAQs for drain clog or blockage clearing projects in San Francisco, 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.
