Do Pergolas Need to Be Anchored Down?

Why Anchoring Is Essential for Any DIY Pergola Kit

When building a structure like a pergola, one of the most common questions people ask is: “Do pergolas need to be anchored down?” The short answer—yes, absolutely. Whether you're using a DIY pergola kit or constructing one from scratch, anchoring your pergola is essential for long-term safety and stability.

Why Anchoring Matters

Pergolas may look open and airy, but they’re still large, heavy structures. Without proper anchoring, a sudden gust of wind can lift or tip an unanchored pergola—posing a risk not only to your structure but also to anyone underneath or nearby. The risk of damage or injury is simply too great to leave a pergola unsecured.

Anchoring Options for DIY Pergola Kits

At Bjorn Woodworks, we always recommend anchoring your pergola using one of the following methods, depending on your installation environment:

1. Setting Posts in Concrete (Most Stable Option)

For the highest level of durability, your vertical uprights can be set directly into the ground with concrete footings at least 2 feet deep. This is especially ideal for freestanding pergolas placed in yards or gardens without an existing foundation. It creates a permanent, immovable base that resists wind and ground movement.

2. Mounting to an Existing Cement Pad

If you’re installing your pergola on a patio or concrete slab, you can securely anchor it using concrete anchors and Bjorn Woodworks’ pergola foot brackets. These heavy-duty brackets are designed to hold your vertical posts firmly in place and are one of the most common and convenient options for residential builds.

3. Attaching to a Structure (Wall or Roof Mounting)

Pergolas can also be anchored to an existing structure like your home or garage. In these cases, you can use wall-mounted brackets or sky lift brackets to tie the pergola into a wall or roofline. This method not only increases stability but can also help integrate the pergola more seamlessly into your outdoor space.

Are There Cases Where Anchoring Isn’t Necessary?

In our experience—very few. Just about every pergola, no matter how big or small, benefits from being anchored. The only possible exceptions might be temporary or decorative pergolas used indoors or in fully enclosed patios, but even then, it's best to secure the structure for peace of mind.

Final Thoughts

If you’re building with a DIY pergola kit, anchoring your structure is one of the most important steps you can take to ensure it stands the test of time—and weather. At Bjorn Woodworks, our foot brackets, wall mounts, and complete bracket kits are all designed to make this process straightforward and secure.
