Should Pergola Wobble?

A pergola is a garden structure with a trelliswork roof that is supported by posts or columns and they are often used to create an outdoor room or space. Many people wonder if a pergola should wobble or not but what happens when your pergola starts to wobble? Is this something you should be concerned about?

Should A Pergola Wobble?

A pergola is a garden structure that many homeowners choose to add to their property but should a pergola wobble?

There are a few things to consider when answering this question.

First, the material that the pergola is made of can affect its stability as if the pergola is made of wood, it is more likely to wobble than one made of stone or metal as wood is a material that can expand as well as contract with changes in temperature and humidity.

Second, the size of the pergola can also impact its stability as a larger pergola is more likely to wobble than a smaller one.

Finally, the location of the pergola can also play a role in its stability so if the pergola is placed on uneven ground, it is more likely to wobble than one that is placed on level ground. In general, it is not advisable to have a wobbling pergola.

Why Does A Pergola Wobble?

Not Properly Anchored Into The Ground:

The best way to avoid this problem is to make sure the ground is level before you install your pergola and if you already have one but is wobbling then it might be due to this reason.

Beams Are Not Properly Attached:

One sign that your pergola is not installed properly is if it begins to wobble and this can be caused by beams that are not properly attached to the posts. If you notice your pergola wobbling, check the beam-to-post attachments.

The beams should be securely fastened to the posts and if they're not then tighten them up and see if that solves the problem. If the wobbling persists, it's likely that the posts are not installed deep enough in the ground.
