Anchoring a pergola to an existing structure is the most secure way to add this garden feature. But what if you want to add a pergola and don’t have an existing structure to attach it to? You can still anchor a pergola without drilling by using heavy-duty hardware. With the right supplies and some elbow grease, you’ll have your new pergola installed in no time.

If you’re looking to add a pergola to your backyard but don’t want to deal with the hassle of drilling into your patio, don’t worry! There are ways to securely anchor your pergola without damaging your outdoor space. With a little bit of planning and the right materials, you can have a beautiful, sturdy pergola that will last for years.
Step One: Find the Right Location
It’s important to find the right location for your pergola before you start drilling any holes. You’ll want to make sure that the pergola is in a spot where it won’t be in the way, and that it will be able to support the weight of the structure. Once you’ve found the perfect location, mark the four corners with stakes.
Step Two: Set the Posts
To set the posts, first dig a hole that is at least two feet deep and wide enough to accommodate the post. Center the post in the hole, making sure that it is level and plumb.
If you are using 4×4 posts, you will need to concrete them in place. To do this, mix some concrete in a wheelbarrow and then fill the hole around the post, using a trowel to pack it in tight. Make sure that you leave about six inches of concrete at the top of the hole. If you are using 6×6 posts, you can either concrete them in place or set them in gravel.
Once the posts are set, allow them to cure for at least 24 hours before moving on to step three.
Step Three: Install the Beams
Now that the posts are set in concrete, it’s time to install the beams. This is a two person job. Have one person hold the beam in place while the other person drills pilot holes and attaches the bolts. Drill one hole near each end of the beam, about 2 inches from the edge. Be sure to drill through both beams at once so the holes line up perfectly. Attach each beam with a washer and nut, using an adjustable wrench to tighten.
Step Four: Add the Lattice
To add the lattice, first measure and cut the panels to size. If you’re using pre-made lattice, be sure to cut it an inch or two shorter on all sides so that it will fit snugly into the pergola frame. To attach the lattice, first predrill some holes along the top and bottom rails. Next, use screws or nails to fasten the lattice panels into place.
Step Five: Finish Up
After the concrete has set for at least 24 hours, you can remove the temporary supports and finish up your pergola. If you’re adding pavers or stones around the base of your pergola, do that now. You may also want to add finishing touches like trim or molding to the top of your pergola posts.
If you’re looking for a fast, easy and relatively inexpensive way to anchor your pergola, the most obvious solution is to use footing blocks. By pouring concrete footings and attaching the pergola to them, you’ll be able to securely anchor your structure without having to drill any holes. This method is also ideal if you’re putting your pergola on an existing patio or deck and don’t want to damage the surface.
