"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."

"Elsy ( I believe she was the plumber from your company via Angi) arrived as scheduled, on Saturday, 09/28/2024. She attempted to repair my garbage disposal unit but was unable to do so as the unit's wiring was worn out. I advised the unit is 40 yrs old. She recommended to purchase a new one. We made a trip together to the local Home Depot store and I purchased the same brand s she recommended. She installed it in record time (within the 2.5 hrs) and completed the job. She also cleaned the work space and carried the old one to my recycling bin. Very satisfied with her work. Also, I want to know if I will receive a billing statement for my records? Thank you for your time & assistance."

"These guys are the best. Did a partial home repipe of both the water and drain pipes. Other plumbers tried to upsell us by replacing newer pipes and the water heater. Ray and Alex just did the repiping that was necessary. Excellent communication, friendly and on time. Even worked in tough, rainy conditions. Ray owns his own business and takes pride in his work. Recommended him to all my neighbors."

"He finished the two jobs more efficiently and economically than I had hoped for, explaining all my options and his pricing ahead of time. This was very reassuring, so I didn't have to worry how things would turn out. I couldn't be happier, thank you for recommending him!"

"Service plumber arrived on site, on time and was ready to begin. He was friendly and professional. He was fully aware of the problem and what needed to be done. He acquired the necessary parts and changed them accordingly as proficient as possible. Our bathroom sink drain issue was completely resolved and ready. Thank you Eric for a great job!"

"Overall they did NOT do what they were paid to do. 1) They were paid $25,000 to document and remove the contents and on numerous occasions they opened a drawer and took one picture, or they missed an area entirely. I would say about 30% of the contents were documented in this way. Their job was to document everything so we could file a comprehensive claim. I personally spent over 150 hours working on the contents inventory to make up for their shortcomings. 2) They were paid an additional $5,691.95 to clean some of the contents that could be salvaged. Numerous items, we can only document 14 of them, are missing from the cleaned contents totaling a value of over $7,000. WDR's response was oh we made a mistake and disposed of those items and you will be reimbursed by the insurance company for their value (of course depreciated) so no harm was done. Of course there is harm!! These items had not only material but sentimental value! We lost everything in my parents home of 50+ years and they just threw the things away. Very Very unprofessional. 3) In the boxes of items that were cleaned and returned we have found items that were never ours, how many people have they switched or lost items on??"

"A great and very professional experience from start to finish. Nato and his crew from the first day to the last arrived on time, worked very hard, cleaned up every day after themselves, knew what they were doing, worked with us on design changes, provided suggestions that were value added and always respectful of the original design. It was a real pleasure to work with people that are very respectful and professional. Even thought we had a lot more rain than is expected for this time of the year, they continued to work and finished on time!! I cannot stress how easy it was to work with these people! I would not think of hiring anyone else and intend to hiring them again for our next project!"

FAQs for sump pump or interior foundation drains installation projects in Lagunitas-Forest Knolls, 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.
