"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."

"Look, you're not calling a company like FWDR because something happy has happened... Our refrigerator flooded our kitchen - exposing a small, long-term leak that had slowly destroyed our cabinets, drywall, and floors without for years our knowledge. We now had ourselves a water damage AND a mold problem and had no idea where to start. We were lost and stressed and didn't know who to call. I did a quick search and found FWDR because of all of their amazing Yelp reviews. One call to FWDR turned a stressful situation into a manageable project with knowledgeable support all along the way. Javier was always able to quickly and patiently answer my questions (and I had a lot of questions), he referred us to several companies to deal with prerequisite issues (asbestos and lead testing and removal), and it felt like he was there to walk us through the whole process. I can't tell you how much I appreciate the patience and consideration Javier, Santos, and Margarita showed every step of the way. They worked with the other vendors and my insurance directly to make sure that no time was wasted between services from different companies, the work was quick and thorough (proof received through testing), and every consideration was given to my family with two toddlers and small home during a pandemic - they did their very best to work around us and our day to day needs. I can't thank them or recommend them enough. Attentive, detailed, courteous, patient, thorough, and going well above and beyond in customer service - you really can't ask for more from a company you never really want to have to call in the first place!"

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.
