How Much Does a Pool Cost in Janesville?
Most fiberglass pool installations in Janesville range from $50,000 to $130,000, depending on pool size, backyard access, soil conditions, and the features you choose. Janesville's favorable soil -- a mix of loam and clay with generally good drainage -- means excavation is straightforward on most residential lots, keeping costs predictable.
One of the biggest advantages of building a pool in Janesville is value. Property costs and contractor rates are lower here than in Dane County, which means more of your budget goes toward the pool, patio, and landscaping you actually want. Lots along the Rock River corridor and on the east side tend to be generous, giving you room for a full-size pool with a deck, fire pit, or outdoor kitchen.
Our pricing follows a simple $1,500 per linear foot rule so you can budget accurately from day one. No hidden fees, no surprise change orders -- just honest pricing from your neighbors down the street.
