At American Construction, Plumbing and Electric, we’re a full-service remodeling and construction company proudly licensed in General Contracting, Plumbing, Electrical, and HVAC. With all trades handled in-house, we provide streamlined project execution from start to finish—eliminating the delays and miscommunication that come with outsourcing. Backed by over 30 years of combined experience between our business partners, we deliver professional, code-compliant work across all phases of residential and light commercial construction. From kitchen remodels to full home renovations, we’re your one-stop solution for quality craftsmanship and reliable service.

"We originally wanted to wait until our spa was fully finished to leave a review, but we just had to rave about Gabe and his team. They have been SO easy to work with—and when you’re opening a second spa location in San Diego, easy is everything. Gabe moved fast (he’ll be done by Monday—EEK!), and for business owners, time is money, so having a contractor who’s in and out efficiently is HUGE. During the project, he discovered some mold in the building. Not only did he notify the property owners immediately, but he also took care of the remediation, followed all proper protocols, and handled it all on his own. We’re forever grateful for how quickly and professionally he resolved it. Honestly, our favorite thing about working with Gabe is how he consistently goes above and beyond—especially in ways we didn’t expect, which meant a lot to us as two female business owners. We never once felt taken advantage of, which sadly can be a rare experience in this industry. To give you an idea of how fast he worked: our space includes five treatment rooms, two storage rooms, a kitchen, an office, and a lobby. He redesigned and completed the whole buildout in just over a month. He’s also a great communicator—sending us frequent updates, photos, and videos of the progress, which gave us so much peace of mind since we couldn’t always be on-site. His pricing is incredibly fair and, in our opinion, makes him unmatched in this industry. His work is impeccable, and it doesn’t break the bank. We truly could not recommend Gabe and his team more!"

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