"The actual onsite plumbing work was top notch. I'm pretty handy and can recognize excellent plumbing work when I see it. Each plumber they sent was very skilled. The reason(s) I did not give them an overall A are: - They're very busy, so getting scheduled in is not quick. - The first visit, the plumber showed up not knowing he was to install a hot water heater. So took a week or so to get them back out. Poor coordination between the sales guy I placed the order with and the service team. - Went thru 2 "advanced tech" recirc pumps before we all gave up and installed the most basic model. Turns out Valley specd this problematic pump but had never worked with it. So probably took a month before the recirc pump issues were resolved. A frustrating process, but am happy with the final result... They did try their best to make things right and to not overcharge me for "debug" time, so kudos to them. So bottom line, these guys are excellent plumbers, though pretty expensive. As always, ask a lot of questions (eg, how many of this model of pump have you installed?) to be sure you're getting what you want. After this experience, I now trust them and would definitely work with them again."

"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."

"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."

"They did a number of things. Braced and restrapped water heater and ran copper line for pressure relief to outside. Unclogged master toilet and reseated. Bolted down second toilet. Reconnected clothes dryer vent. Repaired air gap/garbage disposal and drain line under kitchen sink, crawled under house and remove galvanized pipe straps and replaced with nylon pipe clamps. I was a contractor and used to do this work, o an very critical. They did an outstanding job. Went the extra mile several times. I was expecting a bill for a higher amount but they stuck with their estimate. I recommend them highly and would use them again!!"

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