"We are extremely happy with the installation of a new kitchen sink and disposal. The work was done by Johnathan who was polite and explained everything as he went along. Ours was a little tricky due to some tiles that had to be cut but he did an excellent job and it all came out perfect!"

"Excellent. Two employees did the job. Nice guys. Very polite and they were able to complete a complex job on time. I would definitely hire this company if I ever needed a plumber. The guy who sold us on the job was extremely knowledgeable which is why I selected this company."

"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."

"Great service and quick. Plumber was very knowledgeable. Only negative was the appointment schedule. I was told between 1pm and 2pm but the plumber didn t arrive until 4pm. I think the dispatcher or owner needs to work on how to schedule clients. Plumber for me has no fault in that."

"The work was performed in a timely manner and very professionally. The follow up visit to check the traps left in the crawl space revealed there was still a problem as one trap had a rodent. The technician Said was very thorough and even lifted a plank on the deck to get to the foundation. There he found three entry points that he plugged up. He was extremely careful and replaced all items back where they were before he started. This work had not been done during the initial visit. I am very pleased with the results of this operation, cleaning, replacing damaged vent tubing and wall insulation. A heat shield was also installed. The company has lived up to its promise."

"The team I worked with at BAU was great. I hired them to repair some minor vertical and horizontal foundation cracks that were found in a recent general home inspection. Everyone who came out was upbeat, professional, punctual, thorough, and highly detailed. Hunter came out first to check the entire foundation and give a free estimate. They then split the work up into two dates, and each crew was great. Michael and James came out first for the initial round, and then Alexander and Gabe came out to wrap up the last few areas. The guys were always on time, which is greatly appreciated. Both repair teams also did their own additional checks of the surrounding areas, also greatly appreciated. They were also able to provide before and after pictures, and were respectful of the property."

"Very well, he came out last Friday, they were on time. Armin Rios was very thorough, very confident and very clean and he replaced the pipe. We hadn't asked for him to replace the pipe, but he said this pipe needs to be replaced he was very efficient. He installed a garbage disposal and a faucet."

"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.

"It ended up all that had to be done was plug in the existing sump pump in the new house we bought, but the service person was very nice and professional, and we weren't charge for the visit. They could have told us it wasn't working and we needed a whole new system, if they were dishonest. I can't speak to their actual installation, since we were lucky enough to not need it, but if we did need a new system I would certainly have them back."

FAQs for sump pump or interior foundation drains installation projects in Danville, 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.
