"We had a great experience with Jo & his team! Jo made sure we took advantage of the gas company's energy rebate program & saved us thousands of dollars. His crew was professional, prompt & thorough, finishing the job in one day. They installed insulation in the crawlspace, made sure our ductwork was in good shape & even provided a new door to the crawlspace! We would hire them again in a heartbeat & highly recommend!!!"

"I was aware that we needed to replace our water heater and took advantage of the deal on Angie's List. Because of summer vacation schedules, I pushed off the installation for several weeks. While I was on vacation, they contacted me that they had some vacation schedule issues for the week of our planned appointment so when I returned home, I rescheduled the installation to yesterday with a two hour arrival appointment. The office confirmed our appointment the day before and the technician called before the arrival time to let me know he was running behind and gave me an estimate of when he would arrive, and again called to tell me the exact time he would be here (I appreciated that they kept me informed and he was only an hour later than originally planned). Interestingly, the appointment was fortunate since our water heater had pooped out the night before! The technician arrived, very professional, and we talked about what he was planning to do before he started, made recommendations for replacement of some of attached equipment and the reasoning why replace, and what the cost of those replacements would be before he started, and gave me an estimate of how long the installation would take. When he finished, he went through the completed equipment with me and left a clean worksite. Trace was an excellent representative for the company. I would use this company again if needed."

"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!"

"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."

Sump Pump Installation questions, answered by experts

If you have a self-cleaning washing machine but you’re still seeing lint, your water pump filter might be clogged. To clean it, you should unscrew the drain hose, then remove the water pump filter. From there, you can inspect it and clean it with warm water before replacing it. Check to be sure your washing machine is functioning by running a short cycle. 

Several indicators suggest it's time for a sump pump replacement. A key factor is age; if the pump is over 10 years old, its lifespan is likely ending. Performance issues are also clear signs, such as the pump running constantly, cycling on and off frequently, making unusual noises or vibrations, or failing to function at all. A faulty or burnt-out motor is another definite sign a replacement is needed. Additionally, if you notice any signs of incorrect installation, the pump should be replaced. For a definitive diagnosis, a vetted plumber can assess the pump and confirm whether a replacement is necessary.

Yes, many providers offer warranties for new pumps and labor. Confirm terms before scheduling.

If you notice any new sump pump noises, such as persistent clanging or gurgling, then you likely have a sump pump problem on your hands. Foul odors coming from the pump can also indicate problems. Additionally, if your unit turns on but doesn't pump water, you might have to address electrical problems. In any of these cases, it's a good idea to hire a professional to address the issue.

Yes, it’s normal (and beneficial) to have a small amount of water in the bottom of your sump pit. It shows that your system is collecting groundwater, rain, and excess water from around your property—just like it’s supposed to. However, if the sump pit is always full, you might have a leak or a faulty sump pump.
