Winter presents a unique set of challenges for any outdoor equipment, but in-ground trampolines require a completely different maintenance strategy than standard above-ground models.
Because these systems are integrated directly into your landscape, you are not just protecting a metal frame and a jump mat; you must manage a subterranean pit, a retaining wall system, and sub-surface drainage.
While flush-to-ground models are inherently protected from high winds and displacement, freezing temperatures, subterranean moisture, and even local wildlife can cause severe damage if ignored.
Let’s break down the exact steps you need to winterize your in-ground setup. Doing this right means your trampoline will survive the freezing temps and be ready for jumping the second spring rolls around.
Analyze Your Winter Risk
Your winter prep depends heavily on your local climate and soil type. Before we get to the actual steps, figure out which category you fall into so you know exactly what to watch out for:
- Mild winters (rain, no snow)
- Make drainage your top priority and keep the jump mat dry.
- Freeze and thaw cycles
- Watch out for frost heave. You’ll need to monitor the surrounding area in the in-ground trampoline and make sure water isn’t freezing in the pit.
- Deep freezes and heavy snow
- Keep the heavy snow off the mat to save your springs, and double-check your drainage to prevent a frozen, flooded pit.
- High Water Table/Sump Pump Systems
- Ensure your sump pump is functioning and discharge lines are clear of debris.
Different soil types react differently to freezing temperatures. Expansive soils, such as heavy clay, hold onto moisture. When the ground freezes, this trapped water expands, exerting massive hydrostatic pressure against the retaining wall in a process known as frost heave.
If your pit lacks proper drainage, this pressure can warp the steel frame or collapse the wall inward. Conversely, sandy soils drain well and present a lower risk of frost heave, but require a highly stabilized wall to prevent erosion from winter runoff.
The Hidden Winter Threat: Wildlife Intrusions
An often-overlooked aspect of in-ground trampoline ownership is the space beneath the mat. When temperatures drop, the empty space under your trampoline becomes a perfect, wind-proof hideout for neighborhood animals trying to escape the cold.
Snakes, raccoons, and mice love nesting in these pits or digging into the retaining walls. Mice are especially annoying because they’ll gladly chew right through your expensive jump mat or safety pads just to steal material for their nests.
Prevention Strategy: Before you cover everything up, get in the pit and clear out all the dead leaves, twigs, and junk that critters use to build those nests. If you are applying a winter weather cover, ensure it fits tightly around the perimeter. For properties adjacent to wooded areas, homeowners can place natural, non-toxic deterrents around the perimeter of the pit.
Step-By-Step Guide to Winterizing Your System
Prevention is always less expensive than repair. Complete this full inspection and maintenance routine before ambient temperatures consistently drop below freezing.
Step 1: Manage the sump pump and drainage (crucial)
If your installation uses an active sump pump due to a high water table, inspect the basin for debris.
More importantly, inspect your exterior discharge pipe. If water gets trapped in that pipe and turns to ice, your pump will burn out trying to push water against a solid blockage, causing the pit to flood and freeze. Ensure the discharge line directs water at least 20 feet away on a downward slope.
Step 2: Scrub the mat and clear the pit
Don’t leave rotting leaves sitting on your trampoline all winter. Dirt and dead leaves trap moisture directly against the mat and pads, which breeds mold and breaks down the fabric a lot faster than normal wear and tear.
Grab a bucket of warm water and some mild soap (nothing too harsh) and give the mat and pads a good wash. Just make sure everything is 100% dry before you move to the next step.
Step 3: Inspect and grease the springs
Pull back the safety pads to get a good look at your frame and springs. You’re looking for any early signs of rust or springs that look like they’ve lost their bounce.
Next, hit the frame joints and spring hooks with a silicone spray lubricant. This gives the metal a nice waterproof coating to fight off rust, and it keeps the springs from seizing up or getting super squeaky when the weather fluctuates.
Step 4: Secure the vented safety pads and install a cover
Using a high-quality, breathable weather cover prevents snow, rain, and debris from directly resting on the mat, while still allowing vital airflow to prevent condensation buildup underneath.
Because in-ground models sit flush with the earth, standard covers won’t work. Ensure you use a cover designed for your specific system, anchoring it securely to the retaining wall or ground pegs so high winds cannot catch the edges.
Step 5: Manage snow load to prevent metal fatigue
While commercial-grade in-ground trampolines support significant dynamic weight (jumping), static weight (sitting snow) causes a different type of stress.
Leaving hundreds of pounds of wet snow on the mat for weeks places continuous tension on the galvanized steel springs. Over time, this constant static load can cause metal fatigue, forcing the springs to permanently stretch and lose their recoil memory.
Clear snow from the trampoline at least once a week during active storm cycles, and never use a metal shovel. The sharp edges will easily slice through the woven mat fibers. Use a soft-bristled push broom to safely pull the snow off the surface.
Crucial Winter Safety Rule: Protect the Bounce System from Micro-Tears
Polypropylene is highly durable, but the material inherently loses its elasticity and becomes brittle in sub-freezing temperatures.
Never walk or jump on a frozen or slippery mat. The concentrated pressure on the brittle woven fibers will cause microscopic tears that eventually lead to a complete structural failure of the mat. If ice builds up on the surface, allow it to melt naturally.
The Technician’s Notebook
“In our experience servicing hundreds of in-ground pits, winter frame damage almost always traces back to poor drainage. If you take care of the water under the ground, the trampoline above the ground will survive the winter just fine.”
Can You Use An In-Ground Trampoline During Winter?
A well-maintained in-ground trampoline can provide a safe experience in cold weather, provided the conditions are right. However, you must strictly avoid using the trampoline if you observe any of the following:
- Temperatures are at or below freezing (32°F / 0°C).
- Ice or snow is present on the mat.
- The surface is wet or slippery.
Quick-Reference Winter Maintenance Checklist
| Component | Maintenance Action Required | Warning Signs to Look For |
| Jump Mat | Sweep snow weekly; wash with mild soap. | Fraying stitching, micro-tears, stiff texture. |
| Springs & Frame | Inspect and apply silicone lubricant. | Surface rust, squeaking, over-stretched coils. |
| Drainage / Pit | Clear debris from basin; check discharge pipe. | Standing water in the pit, clogged pump screen. |
| Safety Pads | Clean, dry, and secure under a weather cover. | Trapped moisture, mold/mildew, rodent damage. |
Frequently Asked Questions
Do I need to run my pit’s sump pump in freezing weather?
If the ground is completely frozen, water is not actively seeping into your pit. However, during periods of snowmelt or transitional weather, the pump must be active to clear the water before the temperature drops and freezes the pit solid. Ensure your discharge line is clear.
Should I completely remove my trampoline mat for the winter?
If you live in a mild or moderate climate, cleaning the mat and using a tight weather cover is enough. If you live in an environment with harsh, prolonged deep freezes and heavy snowpack, the safest way to protect your investment is to unhook the springs and store the mat indoors until spring.
Can a standard above-ground cover work for my in-ground trampoline?
No. In-ground covers are specifically designed to sit flush, account for vented safety pads, and prevent the pooling of water at ground level. Always use a cover designed for your specific brand and model.
