"The provided installed two skylights, scraped and retextured the ceilings, made the attic easily accessible with a pull drop-down ladder, installed a fan in the roof of the attic to keep the attic cool (the fan kicks on at 80 degrees), repainted the interior, made wall repairs, and installed new bathroom fixtures. The workers were professional, friendly and usually prompt. Called when they were running late or needed to reschedule."

"Gil is a pleasure to work with. After my initial contact he came by as scheduled to review the job site and meet with me. Work was scheduled that same week and completed in 3 work days. Gil’s crew was skilled and efficient. Gil did note that I had some drainage issues and recommended the addition of drains to the concrete project. His price for the drain was competitive and would insure that my side yard drainage issues that occurred during heavy rains are remedied. Gil and his crew poured/finished a beautiful new walkway. They also did an excellent clean up when finished. I highly recommend GM Pacific Pro (Gil) and plan to use his excellent skills in the future for more projects."

"Ericsen came out and took care of a very troublesome leak. I had multiple companies out trying to find the leak and he was the only one to find, diagnose and provide a detailed list of options for repairs. Ended up getting my home repiped, which was done within a day and he followed it up with drywall and stucco patching. Amazing company and amazing individual. Found my plumber for life!"

"Our technician, Dameyan Jackson, called the night before the day of service to let me know the time that he would be here to service our system. On Friday, he called to let me know that he was available to come earlier than scheduled, if I would like. He arrived shortly after the phone call, came in and quickly recognized that the pump had failed. He was very knowledgeable and professional. I was very pleased with his service and look forward to him returning to install a new pump."

FAQs for sump pump or interior foundation drains installation projects in Mountain-pass, 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.
