"NWP installed a new furnace in my home, for which they overcharged me by $3,379, based on the contract they wrote. The job was "completed" in early October, when they demanded the final payment. I asked if they had received approval on the final inspection for the permit, and they assured me they had. In February, while at the Permit Office in Vallejo, I was informed that I still had an open permit with them, that they had not had the final inspection. That permit will soon expire, if it has not already. By that time, one of the ducts they had installed had fallen down and torn; the wires leading to the thermostat had also fallen down across the door. I called and asked them to come out to fix, and to schedule the final inspection. They never showed. When I called to ask where they were, they rescheduled. At that later date, they sent out a technician to survey the problems; he promised he would return the following Thursday to fix them, and would schedule the inspection for Friday morning. None of these things occurred. I texted him and received no reply. So, at this point I have a working furnace, drooping and torn ducts, falling wires, no final inspection, and am missing one register because it was taken to match the size by the technician. I am moving to file a complaint with the Contractors State License Board. I would recommend you find someone else for the job. P.S. Just discovered that their license has been suspended by the CSLB for failure to post a bond."

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