"The need for a footing drain was a surprise to me during my basement remodel due to water leaking in through the blocks. Raman and his team got me on the schedule fairly quickly, did a great job. They also set up new plumbing for 2 bathrooms and a kitchen in the basement, and removed my old water heater and installed a tankless water heater. Any issues that came up, they were very quick to resolve (including an old copper pipe that they didn't install which welding came loose, and they were there same day to fix.) great honest service, reliable service. Pricing, well, plumbing is not cheap, but I think they are comparable to anyone in the business. I would definitely use them again. Thanks Drain Pro!"

"I had my sump pump replaced. Blaine explained all my options. I decided to have him replace the pump, install a deeper pit, replace and pipe the discharge line and tie it into my gutter downspout. He and his co-worker arrived right on time. They were friendly, polite and made sure to explain all the work that they were doing. He made sure that the pump operation could not be heard from inside the house. I highly recommend Seatown and plumber Blaine in particular"

"The three Techs did a great job of removing all the old bat insulation. Cleaned the attic, then sprayed the Intier attic space with mold neutralizer, before installing the new insulation. Arrived at 8:45, completed the installation cleaned the Intier area, and left by 2:30. Great group of Guys. Money well spent!"

"We had a tricky leak that needed tracking down. We could hear it, but not see it. Our usual plumber was not available, so found Schmitty's on AngiesList and called. Thankfully, he was available to come out that afternoon, and after some detective work we finally narrowed down the area. It was evening by then, so he brought Trace out first thing in the morning to dig under the foundation and expose the leak. Between the two of them, they solved the issue... which turned out to be not one, but four pinholes in the copper pipe underneath the cement slab foundation. Brian said it might be the trickiest soldering job on the least amount of available pipe (1/4") in a very tight area in 20 years. Their pricing was reasonable and fair for an emergency service. Would definitely call them again. Thanks Schmitty!"

"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 Greenwood, 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.
