Reasons To Not Leave Concrete Forms In Place
1. Additional Part To Maintain and Repair
Can you leave concrete forms on for too long?
Yes, you can leave concrete forms on for too long if they are structurally exposed or frail. While these forms offer stability in the short term, they can easily become a liability over the long term.
There is nothing wrong with leaving the concrete forms in place if you feel the structure is safe and they are not going to break down easily.
However, most people aren’t sure of this and that is a risk not worth taking.
You are going to end up with an additional part of the setup that needs to be maintained and/or repaired in the coming years.
This is usually not worth it and it is best to take out the concrete forms whenever you get the chance to do so.

2. Can Start To Break Down
Leaving wood forms in concrete is just not a good idea.
You are going to have a situation where they will look good for a while but then you are going to end up with issues surrounding decay.
This is why anytime you are using concrete forms, you will want to think about breakage. If the material is not going to last, it is not worth it.
These forms serve a purpose in the beginning, but might not be ideal for a long-term setup.
Keep this in mind when you are considering this as an option.
3. Makes Repairs Harder
You never want a situation where you are removing concrete forms too late.
This happens when you realize things are breaking down in a few years and then it becomes difficult to diagnose the issue due to the forms.
You might also have a situation where the repairs are simply harder.
This occurs because you are impatient or didn’t take the time to focus on how you are going to repair the concrete later.

4. Doesn’t Show The Sides Of The Concrete
You are not going to see the sides of the concrete.
This is difficult as you always want to assess the work that has been done along the sides and whether or not it matches what you are hoping for.
Consider this and make sure you are diligent when it comes to ensuring the forms are kept in place only when you are certain about the work that’s been done.
Focus on this when it comes to deciding one way or the other.
