Trampoline assembly: what to know

What the job involves, what changes the price, and what to ask a pro.

What trampoline assembly is

Trampoline assembly connects the frame, the springs or bands, the mat and the safety net, then anchors or levels the trampoline so it sits securely on the yard. People hire it when the frame is large, the springs are hard to hook, or the net and enclosure must be set up correctly.

Signs you need it

  • The frame, springs and mat arrive in boxes, and the springs are hard to attach by hand
  • The net poles and enclosure must be fitted and tensioned
  • The yard slopes, and the trampoline must be leveled before it is used
  • The trampoline must be anchored against wind, or moved to a new spot
  • The mat has torn, or the springs have rusted, and the old set needs checking

What the pro does

  • Lay out the frame in a clear area, matching the legs, rails and spring positions to the manual
  • Attach the springs or bands with the tool the kit provides, hooking them evenly around the frame
  • Fit the mat and check that it sits evenly across the frame without wrinkles
  • Set the safety net poles and enclosure, and tension the net at each pole
  • Level the trampoline and anchor it to the ground with the anchor kit
  • Check the springs, the net and the pads for gaps, then show the owner how to inspect them

What changes the price

Every job is different, so we do not publish prices. These are the things that move the quote up or down.

  • Trampoline size and shape, such as round, square or rectangular
  • Number of springs or bands, and whether the kit uses springs or elastic bands
  • Whether a safety net enclosure is included, and how many poles it has
  • Ground type and slope, and the anchor method the surface needs
  • Access to the yard through gates and side paths
  • Whether the old trampoline must be removed and taken away

What a written quote should spell out

  • The trampoline size, shape and type, with the net and enclosure named
  • The number of springs or bands and the spring tool used
  • The anchor kit and ground anchors supplied
  • A safety check of the springs, mat and net, shown as its own line
  • Removal and haul-away of any old trampoline or packaging, listed separately
  • Warranty on the assembly work, and what the manufacturer covers

Questions to ask before you hire

  • Will the trampoline sit level on my yard, and how do you handle a slope?
  • How do you anchor it against wind?
  • Are the springs or bands tensioned evenly, and how do you check?
  • Does the enclosure net close fully, with no gaps near the poles?
  • Where should the trampoline sit for clearance from fences and trees?
  • What do you check during the safety inspection before you leave?
  • What warranty covers the frame, the mat and the springs?

Red flags

  • They skip the anchoring and say the trampoline will stay put without it
  • They set the trampoline on a slope without leveling it
  • They leave gaps in the net near the poles or the springs
  • They finish the set with springs from another kit
  • They do not show you the clearance zone or the rules for use

What you can do yourself

A homeowner can clear the yard, pick a flat spot away from trees, fences and overhead wires, and sort the parts against the list before assembly. Attach the springs with the included tool, and anchor the frame with the kit's anchors once the spot is confirmed level. Call a pro if the frame is large, the spot is sloped, or the net and enclosure need careful tensioning.

Licenses and permits

Trampoline assembly is not commonly a licensed trade. Anchors that go into concrete or a structure can need a permit, and some areas have rules on backyard structures, so check with your state or local licensing agency and your local building office if you need anything beyond the kit.

Trampoline assembly questions

Does a trampoline need an enclosure?

Many owners use one, and a net enclosure can reduce some falls off the mat. It does not stop every injury, so ask the manufacturer what the enclosure is designed for and how to keep it in good repair.

Can more than one child use the trampoline at a time?

Check the manufacturer's rules on the number of users and the age limits. The manual states those limits, and the installer should walk you through them.

How often should the springs be checked?

Check the springs and the mat for wear, rust or tears regularly, and replace any spring that is stretched, cracked or rusted. Ask the installer for a schedule that matches your use.
