Securing Pergola Posts to a Stone Patio

On the topic of planning where to build a pergola, this question very frequently comes up:

“We have a newly landscaped yard with a beautiful stone paver patio/sitting area. We would really love to build a pergola over the site but our neighbor said that you can’t secure posts to stone – is that true?”

Unfortunately yes, that is true – BUT – there is a very easy work around. Carefully mark out on the patio site exactly where you would place the posts for your desired pergola design. Measure out all angles and distances to make sure your lines are true and level. We suggest marking out the diagonals to the center for a four post square or rectangle design to make sure they are equal.

Once you have the exact placement set, you would need to remove the stone pavers at those spots. Dig holes in the ground to the depth necessary to go below the frost line in your area (if that applies). Typically that is at least 2 feet, but could be more to account for potential frost heave. Pour cement footings and then set in place Simpson Strong Tie bracket mounts. When dry, secure posts into the bracket mounts and return the pavers to surround the posts.

Or like this?

Post secured into concrete footing with stone surrounding.

The concrete footings will provide the stability that the stone pavers could not and will ensure that the pergola would meet any city building codes and, more importantly, that it will stand solidly in place for years.
