"This is the third time I have used Albert Nahman. This time was for a water leak with an unclear origin. They did a great job diagnosing the problem and took the time to explain what they found and offer options on potential fixes. I really appreciate the care their plumber took in tracking down the problem and providing a realistic quote for the cost and time to fix the problem. They also arrive on time and do a great job cleaning up after the work is done. A+++ company. Will definitely use them again the in future."

"I highly recommend Groundworks for foundation concerns. They were very prompt with returning my call and providing a free inspection. I had concerns for my 103 year old home, especially a section of the foundation. Their Inspector, Bob Bloom, arrived on time, was professional and experienced, took time to answer all my questions (thank you for not rushing), and provided me with useful feedback on my foundation and options for repair. Bob gave an honest assessment with no sales pressure. Although I decided to defer foundation work at this time, I will definitely use them in the future."

"Superior plumbing has saved the day for me on countless occasions. I hit a sewer pipe with a lawnmower because it was sticking out of the ground and hidden by overgrown grass. I didn't know what it was, and sewage started coming out a few days later. I had another plumbing company come out and quote me $30k for a sewer lateral. I then had Superior Plumbing come out since they had recently installed a sewer lateral for my parents' house for much less. They said a piece of the pipe fell into the pipe, causing it to clog. They pulled out the piece, then cut the pipe to the ground and put a concrete cap that said "sewer," so I wouldn't hit it with the lawn mower again. It cost $1700 instead of $30k! Last week, the landscapers hit the cast iron sewer pipe coming from the bathroom outside. I immediately called Superior Plumbing, and they came out in 30minutes, as luckily they were close by. They addressed the issue and returned a few days later to replace the pipe with PVS, which proved to be very affordable. I then had them return to strap pipes under the house and install a water pressure regulator, as the water pressure was 95 when it should be 60. This could cause major problems with too high water pressure down the road with burst or leaking pipes. Look no further than Superior Plumbing for your plumbing needs!"

"The job finally got done, but it was a painful process. We called WDR around 9am and were told someone would be at our house between 12pm and 2pm to extract the water. Someone showed up at 2pm and did not have a large enough extractor to do the job. He called for another truck to come with a larger extractor. The 2nd truck showed up with two people in it shortly after 4pm and their extractor was also not large enough to do the job. They estimated that it would take them 5 hours to extract all of the water in our basement with their 100 gallon extractor. They sent the first truck to San Leandro to pick up a sump pump to pump the water out onto the street (fortunately, it was clean water). While the first truck driver was picking up the sump pump, the 2 men in the 2nd truck refused to continue to pump out the water with their truck until we signed their contracts. They provided us an estimate of $1140 when they had been at our house for almost 4 hours without having done very much work. We finally settled on an agreement just as the 1st driver showed up with the sump pump. An hour and a half later, the job was done and the final quote we were given was very fair, almost half of the original estimate. Toward the end of the job, the team was accommodating and worked to reduce cost by sending home everyone but the lead tech.
Having a flooded basement is traumatic and having a water extraction team that wasted so much of our time and energy was not at all helpful. Fortunately, everyone was nice and cordial and we worked out a satisfactory deal in the end, but unfortunately, I can't say that I would use this service again.

"I am re-landscaping my yard and had used Nato before for a small project and he did a good job for me so I asked him to bid this project. His price was competitive. He and his crew arrived promptly, completed the job on time and did quality work. I installed some irrigation lines and landscape lighting conduit during their job and I was pretty slow and it delayed them from filling in their trenches. Nato and his crew were very patient and Nato actually helped me at one point since I was such rookie. My landscape architect wanted the drains to be done a certain way and while it was not the usual way Nato did drains he was fine doing it the way that was requested. I would definitely use him again and told him to use me as a reference."

"Anthony was awesome. He was early. He was fast. He didn't try to get over on me and charge me for anything that I didn't need. I would hire this company again, and probably will when I change out some other sinks. Great experience."

FAQs for sump pump or interior foundation drains installation projects in Knightsen, CA

Most residential pumps draw approximately 1,300 to 2,900 watts when they first start, then settle at roughly 800 to 1,050 watts during normal operation. The exact number depends on the motor’s horsepower and how often the float switch tells the pump to run. Even at the high end, the electricity cost is minor compared with the expense of cleaning up a flooded basement.

Grab a ruler and an empty 18‑inch‑wide pit. During a steady rain, time how much the water rises in one minute. Multiply that depth (in inches) by 60 to calculate gallons per hour, then add 50% for safety. If the result tops 2,100 gallons per hour—about 35 gallons a minute—you’ll need a 3/4‑horsepower unit. Anything lower, and a 1/3- or 1/2-horsepower pump should do the trick.

Loud rattling, constant cycling, or shuddering vibrations are the pump’s way of telling you it’s on its last legs. Musty smells, higher electric bills, and visible rust are other red flags. If the unit is 10 years old or older and exhibits any of these symptoms, replace it before the next heavy rain turns your basement into a wading pool.

You don’t have to hire a licensed plumber, but you should still bring in someone who installs sump pumps for a living—whether that’s a plumber, basement‑waterproofing specialist, or experienced handyman. They know the local codes, can wire the pump safely, and will test the system before they leave. Skipping professional help might void the warranty and could leave you with a pump that fails when you need it most.

Not every basement needs a pump, but if your home sits in a floodplain, has a high water table, or has ever taken on water during a storm, a sump pump is inexpensive insurance. For basements that only struggle with condensation or the occasional damp spot, sealing cracks and improving drainage may be all that is needed.
