"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."

"Schmitty's Plumbing responded to my Angi's service request almost as soon as I submitted it, and they beat out three other Angi plumbing companies in terms of pricing and transparency. I hired Schmitty's to remove an old double bowl kitchen sink and faucet with a new single bowl sink and upgraded faucet. There was no upselling or attempts to convince us to replace our garbage disposal which two of the other plumbers recommended we do. We saw no reason to replace our disposal which functions well and is not that old. Partners Drake and Gage came out to our home as scheduled, and they got to work immediately working efficiently and thoroughly. We appreciated their no-nonsense, honest, prompt service, and very fair pricing. I chose Schmitty's based on the positive customer reviews, and would hire them again. I told them I would recommend them to all my friends who have plumbing needs!"

"They did a great job, we had some sewer replacement work done and a tankless installed. We love the tankless and haven’t had a single issue with our sewer since. It was so worth it, and they were quick and efficient!"

"Tyler, Danny, & Juan were friendly, professional, and very efficient. They cleared out all the old insulation and rodent leavings under our house Friday in 4-5 hours. Monday they installed insulation, thick white plastic and sealed up the crawl space with a de humidifier and were done by 3:30pm"

"Had a great experience with WA Evergreen Insulation from start to end. Rob came to my house, quoted me an insulation install, made absolutely sure that they would not cover any existing knob and tube with insulation and prevent a fire. The crew showed up and completed the job in one day. Once they got started it was clear they knew exactly what they were doing - and they managed to shimmy into the extremely small attic access and cleaned up my rat jerky in the crawlspace! I'm very happy with this job and with this company!"

"Determined sump pump failure was not due to electrical issues. They kept me posted by text prior to arrival. Showed up on time. And even made phone calls to a plumbing group to get them out as soon as possible. The tech went out of his way to get us the help we needed."

"Everything went well and smooth with their help. I got the proposal with all details at the same day when they came to do the estimate. Our old furnace was built on 1971, and it was in a closet next to the water heater tank. When one other company came to estimate, they wanted to cut a furnace size hole on the wall facing the hallway to fit the machine and we have to find a constructor or handy man to finish, like to build a door or make it look good, but G&S figured out an easy way, which is to turn the machine toward another direction and eventually only cut a vent on the wall. It took two days for all the installation, and they cleaned up when they left and everything looked clean and nice. They also listened to customers. We didn't want the heat pump to be right next to the stairs of our deck, so they chose a spot which was few feet away from the closest spot without any question. We appreciate for that, since the wind blows out from heat pump is kind of strong, and we feel comfortable with where it is at now. One thing I really like is they were on time, and they called around 30 minutes ahead before them showed up. They also take care all the paperwork for the PUD rebate, Costco 10% shop card, and city permits, and all we do is waiting their call to arrange the time."

FAQs for sump pump or interior foundation drains installation projects in Sultan, 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.
