Pool excavation costs $1,500 to $5,000 on average in soft soil by HomeGuide's national 2026 figures, and $15,000 to $20,000 in rock. Shale and sandstone near the surface are common around Pittsburgh.
Prices on this page are national ranges from HomeGuide, not quotes from us. On Pittsburgh lots, the slope, the rock, the access up the street and the distance to the dump change the real number. Figures checked October 2026.
How much to dig a pool for an inground pool?
To dig a pool in soft soil without obstructions costs $1,500 to $5,000, per HomeGuide's pool section; its table lists $1,000 to $5,000. Rock ledge, hardpan, boulders or hard access raise it to $15,000 to $20,000. The finished pool is $25,000 to $100,000.
Does a pool builder or an excavating contractor dig?
The pool builder usually hires the excavator. You can hire one directly, but the dig must match the pool builder's layout and depths. On a sloped yard, the builder, the wall designer and the excavator should agree on the plan first.
How long does a pool excavation take?
A pool excavation takes one to three days when the soil cooperates. A pool cut into shale or sandstone, or into a slope that needs a wall, can take a week or more. A small dig takes 1 to 3 days by HomeGuide's estimate.
Is hauling the pool dirt included?
Hauling the pool dirt may or may not be included. A pool makes many truckloads, and HomeGuide puts removal at $140 to $230 per cubic yard or $1,400 to $2,300 per load. On a hillside lot, some spoil can sometimes build a level deck area behind a wall.
How much to fill in an old swimming pool?
HomeGuide has no price for filling in a pool. The work is draining it, breaking the floor so water can escape, removing the top of the walls, filling with clean fill in compacted layers (fill dirt is $5 to $25 per cubic yard) and topping with soil and seed. Your municipality may want a permit.
What if the pool site hits rock or soft ground?
If the pool site hits rock, the dig slows and may need a hammer; HomeGuide says rock can add $15,000 to $20,000. Soft clay or old fill at the bottom is dug out and replaced with compacted stone. The contract should say how each is billed before work starts.
What does site prep for a home addition cost?
Site prep for a home addition combines grading and a footing or basement dig. HomeGuide lists grading for new construction or an addition at $1,000 to $5,000 and foundation excavation $1,500 to $10,000; it gives no separate addition figure. On a slope, the addition may also need a wall.
What does a pad for a garage, shed or pole barn cost in Pittsburgh?
A pad for a garage, shed or pole barn costs about $1,000 to $2,500 to dig and prepare, by HomeGuide's pad figures. On a Pittsburgh slope, a garage pad often means cutting into the hill and building a wall at the back, which adds cost.
