"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."

"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 ."

"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

The cost to repair a sump pump ranges from $400 to $550, depending on the extent of the repair and your location. Minor repairs, like fixing a switch or replacing a float, can cost just a few hundred dollars. However, more significant issues, such as motor replacement or addressing electrical problems, may cost closer to $550. Keep in mind that regular maintenance can help prevent costly repairs, and if a sump pump is beyond repair, a full system replacement ranges between $650 and $1,400.

Costs range from $300 to $1,200, depending on the pump type, issue, and installation complexity.

There are a couple of similar alternatives you may consider for a sewage ejector pump, including a grinder pump or a submersible sump pump. Submersible sump pumps protect your home from flooding from outside water, though, rather than handling wastewater from inside. A grinder pump macerates, or shreds, solid waste before pumping it onward to the sewer line.

Start by calling a plumber if you want to install a sump pump battery backup. Talk to them about your situation and needs. Sometimes, electricians or waterproofing contractors will install a battery backup, and in that case, the plumber you call should be able to point you in the right direction.

A small sump pump running infrequently uses an average of 10 kilowatt-hours (kWh) of electricity per month. The average cost for electricity is $0.171 per kWh. The size and use frequency affect how much electricity it uses. Sump pumps average one-third to one horsepower (hp) motors. One hp is equal to 745.7 watts. Watts multiplied by the time your pump is running divided by 1,000 equals your average kWh. Multiply kWh by your average cost of electricity. In areas with high rain or a marsh basin, the average cost can be as high as $15-$25 a month.
