Hi,
My deck is almost 5 years old and i've maintained it very well. Recently, I noticed that it started sagging from one corner and it is becoming too obvious as once the flat horizontal surfact now is somewhat slanted.
What are my options here ? What can be done to avoid sagging further ?
Thanks for your answers and hints.

Look at the footing under the corner that is sagging. That is probably where the problem begins. Other possibilities would include that you left a gap between the footing and the post, the post and the beam, or the beam and the joists in that area.

Can you tell us a few more details?
How is the deck supported? How many beams are holding up the joist? Are there concrete footings, or just posts sunk into the ground? How many footings or support posts are there? Is it just one end or one support that has sunk? How far has it sunk? How deep in the ground do you think these footings are? I don't know if there is an easy solution or not, but some of the experts on this forum will be better able to help if they know the answers to the above, and a few more questions after that.

Thanks a lot.
The post is sunk into the ground. It doesn't have concrete footings. There are three support posts (two in corners and one in middle) and the one of the side one has sunk about 10inches.

You probably can block up a car jack and jack the deck back level.
Dig out the bottom of the post, and put a pressure-treated or concrete block under it.
Good luck!

Hi,
It sounds like you might live in a cold climate and perhaps when they built the deck, they did not dig below the frostline??? Possibility??
If you use a car jack, please make sure that it is a hydraulic one meant for the old cars ...not the small car ones. Also, make sure everything is secure and very veyr very important:
Make sure you have a solid wide surface underneath the carjack. In other words, do not use grass. Once the support post is cut, the jack will sink unless it is on a solid footing as well.
