"I have had two issues since they installed the new sump pump and irrigation. Issue number one was water still getting passed the new concrete. The other issue is that the new concrete was not level at all which has caused issues with the new flooring I installed. However, their customer service is top notch and will work hard to take care of you."

"I called and Schmitty's told me they could have someone there at 8 AM the next day. They called the next morning and confirmed that the repair team was on its way and two members of Schmitty's staff arrived shortly thereafter, showing up a few minutes earlier than the scheduled time. They were courteous and efficient, and soon had the problem valve apart. It was an older design (40 year old house) and not the brand of valve I'd suggested when I'd called them so they had to go out to obtain the necessary replacement part but they were back soon and the installation went very quickly. The valve works fine now and I'm happy."

"Gardner came to do an inspection of my basement and provide a quote. I had received other quotes that only provided for a single sump pump install at outrageous prices. He was very thorough, took two hours to measure, inspect, provided videos and explanations on everything, and the quote was shockingly affordable with so much more work I was ecstatic! I am getting a three sump pump with back up battery, and so much more for basically what the others quoted. And, to have the option to finance through Greensky was the cherry on top! If you are in King County, ask for Gardner @ GROUNDWORKS - you won’t regret it!"

FAQs for sump pump or interior foundation drains installation projects in Maple Valley, WA

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.
