Semi-Inground Pools in Western PA

Get the look of an inground pool with the versatility of an above ground model.

For homeowners in Western Pennsylvania facing rugged terrain, getting the look of an inground pool with the versatility of an above ground model is finally possible. What do you do if your yard is too sloped for a traditional above ground pool but an inground pool is out of your budget? You choose a Semi-Inground Pool.

These innovative pools are structurally engineered to be buried partially or fully in the ground. This allows you to integrate them seamlessly into hillsides, wrap them in custom decking, and create a multi-level backyard resort that looks like a million bucks, for a lot less.

Why Go Semi-Inground?

Conquer the Slope:

Turn a hilly "unusable" backyard into a stunning poolscape without expensive retaining walls.

Budget Friendly:

Achieve the high-end "sunken" look of an inground pool for about half the cost.

Durability:

Built with thick, insulated walls (aluminum or steel) that resist corrosion and ground pressure.

Extended Season:

Our semi-inground models feature R-10 insulated walls, keeping your water warmer longer than standard steel wall pools.

Why Choose Seven Seas for Your Installation?

Installing a semi-inground pool is more complex than a standard above ground build. It requires precise excavation and grading.

In-House Installation:

We don't hire random subcontractors to dig up your yard. Our own experienced crews handle the excavation and backfill to ensure the pool is structurally sound.

Site Evaluation:

We will visit your home to shoot the grade of your yard and determine exactly how deep we can bury the pool to match your deck or patio.
