Sump Pump Installation Cost Factors 

The main cost factors of sump pump installation in Denver, CO, are pump type and size.

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
1/32,000$800–$1,200
1/23,000$850–$2,600
3/4 or higher3,000+$1,600–$2,500
Dual pumps or multiple pitsVaries$2,000–$4,500

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 TypeAverage Cost
Submersible$1,000–$3,000
Pedestal$800–$1,500
Water-powered$450–$2,600
Battery backup$1,500–$2,600 (add-on)
Crawl space/exterior$1,200–$4,000

Plumber Costs

The other key cost factor of this project is the labor rate charged by your Denver, CO, sump pump installer. Working with a pro plumber who understands sump pumps and their components has many benefits. They understand how to install a sump pump properly and may also offer maintenance tips to help extend the sump pump’s lifespan. On average, these pros charge between $75 and $150 per hour in Denver, CO.

Does Installing a Sump Pump Increase Home Value?

In the Denver Metro area, not all homes have a sump pump installed. This means putting one in your house could increase your home's value, not to mention saving you money in the event of a flood. In Denver, CO, sump pump installation can yield a return on investment (ROI) of between 30% and 50%.

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.
