Get matched with top sump pump installation pros in Seattle, WA

"Had them pump my septic. Quoted me $550 before tax. Charged me an extra $100 to break up the top solid layer, which is a little deceptive since that layer is always there. Will go with FloHawks again next time, they didn't charge me an additional fee to break up the top layer last time I had my septic pumped."

"Diagnostician/Estimator and Plumbing team were just excellent. Sewer work and team very good, but also very pricey. Repairs on system were well done - crawlspace access area was damaged to extract the old sewage tank. Damage is still being repaired by homeowner. Harts rebated some cost to cover access damage. All Harts team members were fully vaccinated, wore masks, and were great to work with. Harts completed work within 1 day within quoted costs. New sewer pump alarm system system malfunctioned right after the install was finished - Harts sent a repair tech out to fix it on next day - excellent service - fixed the twisted tank float problem - no charge. Building inspector noticed new sump pump was tilted and alarm wiring was not properly affixed to the house - minor issues, I would hire Harts again but negotiate hours and pricing ."

"Water had always been a problem for my crawlspace, especially during raining and snowing season. Asking around, installing a French drain and a sump pump appeared to be the solution. I searched around and picked Insulation Co. Estimation without inspection seemed weird at first, but it made totally sense since the foundation layout is all there in the files. Jo had always been responsive, detailed and nice whenever I had questions. Scheduling was easy and Rafael and the team did a great and efficient job onsite. 2 months after the installation, we noticed that there was still standing water and they came back to install more pipes and gravels. We really appreciate the effort."

"Brian has saved us a few times from house leaks. The first time the main was cracked somewhere, pouring water into our driveway. Brian responded to our call for help very quickly, came out the same day and gave us a very reasonable bid (unlike the few other companies we called which asked for large emergency fees before coming out and didn't even have time to come out immediately - 24 - 48 hours out for a main leak!). Brian found where the leak was coming from after digging for a few hours, patched the main line, and installed a new main shut off (previously a wrench was required to toggle the water to the house), all for much less than other companies quoted over the phone. The second and most recent time Brian came out was to assess and fix a downstairs can light leaking water. Brian responded quickly and came out the same day we called. He quickly found the upstairs toilet seal was no longer viable, resealed the toilet, and cleaned out the leaky can light, again for a very reasonable price. Brian is a great plumber and I highly recommend him and his team. Thanks so much, Brian!"

"Harts corrected the location of the crawlspace sump pump discharge line to the location in the foundation which I originally wanted it to be located. However, we did not hear the sump pump operate under the floor when first installed. When the Harts crew changed the location of the pump discharge line, we can now hear the pump very distinctly when it operates, under the floor. I am requesting that Harts come back and listen to see if it is normal for the sump pump to make this much noise."

"The installer was a true professional. In addition, thy were great to work with form the estimate, financing, scheduling. front to back, great service."

"They came out the next day and was able to install a new water heater for me. They even matched the other bid I had received. Very friendly and professional installers."

"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!"
