"Robert was an amazing plumber to work with. Extremely professional, knowledgeable, responsive and honest. All traits that are hard to come by in this profession. Ever since I found his business, Iâ ve never even bothered to look elsewhere. He never tries to upsell you, gives you options and always cleans up meticulously. Iâ ve recommended him to all my friends and family and they were all happy with his services. So far heâ s fixed my clogged sink, installed and repaired my garbage disposal, came immediately when my storm drain busted, and gave me quotes and advice on a tankless water heater. Hopefully I wonâ t need his services any time soon though!"

"Can not imagine a better response, starting with my call for assistance, response time and how the technician, Tad methodically diagnosed the problem. We have an obscure kitchen fixture that required service in Feb 2019. Under warranty the problem was easily diagnosed by me, a problem possibly caused by me and a replacement part sent and installed by Albert Nahman team. Problem: I broke the faucet cartridge. Current Problem: restricted hot water flow in this kitchen sink only. Turns out the new cartridge part is now malfunctioning. I called and Tad arrived taking a step by step approach ruling out possible causes: a clog here or there, build up of sediment, or blockage in the lines or cartridge. The company that sells the product got on the phone with Tad and they collaborated on the problem and the tech person gave Tad one more thing to try. After the collaboration it is agreed, problem persisted and therefore that new cartridge part is now malfunctioning and will be shipped free of charge in two days. Thanks to all, who made this possible and I trust we will have Tad here again soon to finalize this fix. BTW, cost of service was less than expected given going rates for such a call lasting in excess of one hour. Another comment, spending time with Tad during the repair was a pleasure to have him explain, collaborate, listen and just chat. Questions on who to call next time, no question who I will call next time. I have read criticism of costs: In the Berkeley area "How much does it cost to hire a plumber? Some plumbers have a minimum fee for a service call. They might charge anywhere from $175-250 to come out and give you a consultation. Plumbers may give you a general service rate of $128-148 per hour when there are a lot of unknowns about a project and they aren't sure how long it will take. Some charge a flat rate for their plumbing services. For example, you may get charged $175 for a sink or drain cleaning, while toilet installation costs $500." Today costs are upfront, same as charges in Feb, $69 to arrive and assess the problem. Here in excess of one hour for $129 minus $25 coupon, total charge $173. I am ok and I expected these costs. If I was in Philly, where I grew up, I could call an uncle or cousin and get a better rate, a family rate. This is going rate for our area."

"I was apprehensive about this project because the entire, crumbling sectional clay sewer line from my 95 year old home needed to be replaced. Bracing for some crazy expensive bids, I obtained four of them. One was actually crazy; of the other three, I chose Fito for their very professional proposal and excellent value. On the day of the job, they pulled up fully equipped and ready to roll, and knocked it out in a day. Added to that, the entire crew, to a person, were so courteous I considered it a bonus. Satisfied? So much so I had them replace all the drain lines under the house the next day, again for an excellent price. Don't get upsold, cross-sold or down-sold; I believe you can trust this company to do your job correctly and honestly."

"I highly recommend the company (Costello's Plumbing) as well as the employee who helped us (Miguel). My wife spoke with Mr. Costello this morning, and booked an appointment for Miguel (one of his workers) to come over and look at the situation / prepare an estimate. He did so (arriving iwihin the appointment window), gave us a good quote, and indicated the two parts that needed replacement (the garbage disposal unit and the cold water dual shut-off valve. He indicated that we could purchase those parts through the company, or if I had the parts onhand, he could just install them (saving money). Fortunately, The Home Depot nearby was open, and I was able to get the two pieces fairly quickly. Miguel then: * installed the garbage disposal (and took care of getting rid of the old one), * connected the replacement shut-off valve, * replaced the faucet itself, and made sure that none of it leaked. A job well done!"

FAQs for drain clog or blockage clearing projects in Castro Valley, 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.
