Detailed Description

A shed performs best when it’s built on a solid foundation. With our Backyards Prefab Shed Assembly service, we prepare a level base whether gravel or a custom concrete slab—and follow manufacturer guidelines to secure all panels and hardware. From layout and anchoring to final alignment, we make sure everything is square and weather-ready, delivering a durable, functional shed ready to use in your Toronto & GTA backyard from day one.

Frequently Asked Questions

Do I need a concrete slab?

For larger sheds or heavy equipment storage (like riding mowers), a concrete slab is highly recommended for stability. For smaller tool sheds, a leveled paver or gravel base is often sufficient. We can build both.

Do you assemble metal and plastic sheds?

Yes. We have experience with all major brands (Lifetime, Keter, Arrow) and materials. Metal sheds require precise alignment of hundreds of screws, while plastic sheds need careful snapping of panels to be watertight.

Do I need a building permit?

In many GTA municipalities, sheds under a certain size (typically 108 sq. ft., though this varies) do not require a permit. We can help you check your local bylaws during the planning phase.

Why is a Technical Visit necessary?

The #1 reason prefab sheds fail is a poor foundation. If the ground isn't perfectly level, the pre-drilled screw holes won't line up, and the doors won't close properly. Our Backyards Prefab Shed Assembly assessment evaluates the slope of your yard to determine if you need a simple gravel pad, a timber frame, or a permanent concrete slab to guarantee the shed lasts for years.
