4 Steps to Fix A Sinking Deck

There are a few things you can do to fix a sinking deck. First, you need to find the source of the problem. If the deck is sinking because of poor drainage, you need to improve the drainage. This can be done by adding more drainage holes or by installing a drainage system. If the deck is sinking because of rot, you need to replace the affected boards. Finally, if the deck is sinking because of settling, you need to add more support to the deck. This can be done by adding more posts or by installing deck piers.

If your deck is sinking, it is important to learn how to fix it. A sinking deck can be dangerous, and it can also be a sign that your deck is not structurally sound. By learning how to fix a sinking deck, you can avoid these dangers and keep your deck in good condition.

Step 1: Check The Deck For Visible Damage And Repair If Necessary

Check the deck for visible damage and repair if necessary. Look for any cracks or splits in the wood, and use a hammer and nails to repair them. Also, check the posts and beams for damage, and replace any that are cracked or split.

Step 2: Add More Support Beams To The Underside Of The Deck

This step is necessary if the deck is sinking in more than one place. Support beams should be placed at or near the joists that are sinking. The support beams will help to distribute the weight more evenly and prevent further sinking.

Step 3: Repair Or Replace Any Damaged Boards

If your deck is starting to sag or show signs of wear and tear, you may need to replace some of the boards. Inspect the boards for damage and if any are cracked, warped, or otherwise damaged, replace them with new boards. Be sure to check the joists and support beams for any damage as well.

Step 4: Paint Or Seal The Deck To Protect It From Further Damage

Assuming the deck is already sinking, the first step is to lift the deck up and support it with jacks. Then, dig around the deck’s perimeter to expose the footing. Once the footing is exposed, pour concrete into the hole and around the footing. Finally, lower the deck back down onto the new concrete footing and screw or nail it into place.
