Customers say: Super punctual

"The crew from Albert Nahman did a great job from start to finish. The project was to replace the original ductwork in our 60 year old house. Tom provided excellent advice for the estimate then Bryan’s crew did the job, 2 days, within a week of my acceptance of the proposal. Great work."

Founded in 1989 by Dean Henninger, D.W. Henninger Construction has been recognized as a leading builder of custom homes and remodeling projects. Acting as a General Contractor, the entire Henninger team is known to exceed client expectations, leading to a steady stream of testimonials and referral clients.\n\nOver the past two decades, Henninger has managed projects in California: kitchens, bathrooms, room additions, entire home renovation, even complete construction of homes. Regardless of scope, Henninger approaches each project with the same foundation of principals: strong design aesthetics, comprehensive product options, sound project management, and a commitment to craftsmanship.\n\nDesign Aesthetics: With 20+ years of Bay Area experience, Henninger understands the many architectural quirks unique to Bay Area communities, making it easy to elaborate and integrate with established design aesthetics.\nProduct Options: Henninger is truly unique in being a single-source stop for design, remodeling, and product resources. Cabinetry, countertops, appliances, and plumbing fixtures are all available options for your project, and Henninger assists with selection, delivery, even vendor communication if there’s a problem.\nProject Management: Project management is essential to delivering a good customer experience. Henninger prioritizes project management to the same degree as design and crafting. Henninger is unique in using progress billing — a system that only charges for services following completion rather than pre-paying weeks or months before it starts.\nCraftsmanship: Henninger’s team of carpenters bring the best combination of experience and expertise to the table, but they offer much more than technical proficiency — by working with true craftsmen, Henninger projects balance design and functionality for maximum results on each and every project, regardless of scope.\nOur service areas: Oakland, Pleasanton, Livermore, Walnut Creek, Fremont, and surrounding cities. Projects in San Francisco and San Jose are also feasible — contact us for more information.

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.
