In-ground trampoline installation looks straightforward but has real technical requirements that determine long-term performance. The excavation has to be the right diameter and depth for your specific frame. The bottom of the hole needs a drainage layer — typically 12 to 18 inches of gravel — so rainwater doesn't pool under the mat and accelerate frame corrosion. The frame has to be set perfectly level so the mat sits flush with the ground on all sides, and the surrounding ground needs to be graded so water drains away from the opening rather than into it.
We've done enough of these to move through the process efficiently without cutting corners. The drainage layer is non-negotiable on our end — it's the difference between a trampoline that stays in good shape for years and one that starts rusting at the frame from sitting in standing water.
The finished result blends into the yard. No above-ground frame, no trip hazard, no equipment dominating the yard's appearance. It's safer for kids because the fall distance is eliminated, and it looks like it was designed into the space from the beginning. We don't supply the trampoline — you select the model you want, and we handle everything from the ground down.

Common Questions
Do I need to buy the trampoline first?
Yes. You select and purchase the trampoline model, and we size the excavation to fit that specific frame. We work with most major brands in standard round sizes (12, 14, and 15 foot diameters are most common).
How deep is the excavation?
Typically 3 to 4 feet, depending on the trampoline model's frame height. We excavate deep enough for the mat to sit flush with the surrounding ground when the frame is fully assembled.
What about drainage — won't the hole fill with water?
This is the key detail most DIY installations miss. We install 12 to 18 inches of compacted gravel at the base of the excavation, which provides enough drainage capacity to handle significant rainfall without pooling. We also grade the surrounding area to direct surface water away from the opening.
How long does installation take?
Most installations take one full day. Larger frames or difficult soil conditions (clay, rock) may add time.
Can you install in any yard?
We can handle most residential yards. Installations near buried utility lines, tree roots, or in very high water-table areas require evaluation first. We'll assess during the estimate visit.
