The cost of living in Seattle, WA, is one of the highest in the country, which tends to increase costs for home services of all kinds—including installing flood mitigation in your home. Sump pump installation costs in Seattle, WA, range from $889 to $1,667, or $1,222 on average. Your price will mainly depend on pump type, size, and location, though labor rates also play a role in determining the total cost.
Sump Pump Installation Cost Factors
Pump size and type are the main cost factors of sump pump installation in Seattle, WA.
Size
Understanding the size and scope of your sump pump installation is key to estimating your total cost. The size of the pump—measured in horsepower (HP) and gallons per hour (GPH)—directly impacts the price.
Most residential sump pumps are between one-third and one-half HP, which is sufficient for standard basements. Larger homes or those with high water tables may require more powerful pumps.
A larger pump, or one with higher capacity, costs more to install. If your home needs a sump pump with a deeper or wider pit, excavation costs will increase. In some cases, homes with expansive basements or frequent flooding may require multiple pumps or pits, further raising installation expenses.
| Unit Size (Horsepower) | Capacity (Gallons per Hour) | Average Cost |
|---|---|---|
| 1/3 | 2,000 | $900–$1,400 |
| 1/2 | 3,000 | $1,000–$1,800 |
| 3/4 or higher | 3,000+ | $1,400–$2,500 |
| Dual pumps or multiple pits | Varies | $2,000–$6,500 |
Type
The type of sump pump you choose significantly affects your installation cost. There are several main types: submersible, pedestal, water-powered, and battery backup systems.
Submersible pumps are installed inside the sump pit and are quieter but more expensive.
Pedestal pumps sit above the pit, are easier to service, and cost less.
Water-powered and battery backup pumps offer extra protection during power outages. These systems increase your total cost but can be invaluable in flood-prone areas.
Specialized pumps for crawl spaces or exterior installations may also require additional work and cost.
| Pump Type | Average Cost |
|---|---|
| Submersible | $1,400–$3,500 |
| Pedestal | $500–$1,300 |
| Water-powered | $1,000–$2,000 |
| Battery backup | $1,500–$4,500 (add-on) |
| Crawl space/exterior | $1,200–$3,500 |
Plumber Costs
Another key part of budgeting for a sump pump will be factoring in the labor rates of your Seattle, WA, sump pump installer. It’s always worth the investment to hire an expert who knows how to install sump pumps properly. Their working knowledge of sump pump parts means they can help you extend the system’s lifespan through careful installation and specific guidance for future maintenance. On average, you can expect a Seattle, WA, plumber to charge $150 to $200 per hour for this job.
Does Installing a Sump Pump Increase Home Value?
Seattle, WA, is notorious for its high levels of rainfall year-round. This means that many homes have a sump pump installed. Since flooding is a major concern for homeowners in Seattle, WA, sump pump installation can yield an impressive return on investment (ROI) of 30% to 80%. To maximize your financial return, it’s important that you keep up with proper system maintenance over the sump pump’s lifespan.
How Angi Gets Its Local Cost Data
To help homeowners plan their next project, Angi provides readers with carefully researched cost data and upholds strict editorial standards. We start with national average project costs, which we collect by analyzing competitor information, retailer material costs, and input from professional contractors. We then apply local price index data to calculate location-specific estimates that reflect what homeowners typically pay in their local area. To do that, we use data from the U.S. Bureau of Economic Analysis (BEA), including its Regional Price Parities (RPPs), which measure price differences across cities. This helps us account for differences in labor, materials, and overall cost of living, so estimates in higher- or lower-cost areas better reflect real-world local pricing.
Every estimate undergoes a thorough editorial review to verify accuracy, consistency, and alignment with observed market conditions.

Hired Chris Pluming and paid 3000 for a motor replacement for my septic tank, the work is 2 hours.... but never fixed my alarm. I kept calling them and no response.

Plumber called and was able to come earlier than expected. He pointed out that faucet was one that could be expected to fail repeatedly in the future due to a defective part and so I decided to get it replaced. After doing that I asked him to look at toilet which seems to take a long time to...

I spoke with Scott over the phone and we talked about replacing the hot water tank. My husband followed up with his thoughts. We had tentative plan a and plan b. He gave me a verbal quote to replace the tank and suggested I compare prices with other companies. I already had 2 sources and knew...

Kevin came out to give me a quote on a tankless water heater. He was so helpful explaining all the differences between tank and tankless and different tankless models. I was considering a tankless because the space (attic) is so difficult to access but after Kevin told me I could set up a...
