So, you've built a deck, but now it's time to level it? Don't worry, you're not alone. Many homeowners face this challenge. Leveling an already built deck might seem daunting, but with the right steps and tools, it's a manageable task. Let's dive into how you can achieve this.

Before we start, remember that safety is paramount. Ensure your deck is secure and stable before you begin any work. Also, consider the weather. It's best to level your deck on a dry, sunny day to prevent any slips or trips.

Understanding the Problem

First, you need to identify why your deck is uneven. It could be due to settling soil, improper construction, or even rotting joists. Understanding the cause will help you determine the best solution.

  • Cement or concrete mix

  • Tape measure
  • Circular saw (optional, for cutting joists)
  • Safety gear: gloves, safety glasses, and ear protection if using power tools

Preparing the Area

Before you start, clear the area under your deck. Remove any debris, plants, or items that could hinder your work. If your deck is attached to your house, ensure you've turned off any power to the area.

Next, check the footings. They should be solid and well-embedded in the ground. If they're rotting or unstable, you might need to replace them before proceeding.

  • If the soil has settled, you'll need to add more soil or use a cement mix to raise the footings.
  • If the joists are rotting or the deck is sagging, you'll need to replace or reinforce them.
  • If the deck is simply sitting too low, you might need to raise the entire structure.

For minor adjustments, you can use shims or wedges under the footings. For larger issues, you might need to use a cement mix to create a new footing or support beam.

Securing the Deck

After you've leveled your deck, it's crucial to secure it. This will prevent it from becoming uneven again and ensure it's safe for use.

Check all the connections between the deck and the house, as well as between the joists and the footings. Tighten any loose screws or bolts, and replace any rotting wood.

Checking the Level

Once you've secured your deck, it's time to check if it's level. Use your level to ensure the bubble is in the center. If it's not, you might need to make further adjustments.

Also, check the slope of your deck. It should have a slight slope away from your house to prevent water from pooling and causing damage.

Finishing Up

After you've confirmed your deck is level, it's time to finish up. Replace any removed deck boards, sweep the area clean, and dispose of any debris properly.

Finally, consider applying a sealant to your deck. This will protect it from the elements and extend its lifespan.

Congratulations! You've successfully leveled your deck. Now, you can enjoy your outdoor space with peace of mind, knowing it's safe and level. Regular maintenance will ensure it stays that way. Happy decking!
