DIY Deck Repair: How to Fix a Sagging Deck
A sagging deck can be a significant safety hazard and an eyesore in your backyard. Fortunately, with the right tools and a bit of know-how, you can restore your deck to its former glory. In this article, we’ll walk you through the steps to fix a sagging deck, ensuring it’s safe and sturdy for years to come.
Why Does a Deck Sag?
Before diving into repairs, it’s essential to understand why your deck may be sagging. Common causes include:
- Poor Construction: Inadequate support beams or joists can lead to sagging.
- Water Damage: Prolonged exposure to moisture can weaken wood.
- Pest Infestation: Termites and other pests can compromise the integrity of the wood.
- Weight Distribution: Heavy furniture or planters placed unevenly can cause sagging.
Tools and Materials Needed
Before starting your repair, gather the following tools and materials:
Tools:
- Circular saw
- Drill
- Level
- Measuring tape
- Hammer
- Pry bar
- Safety goggles
- Work gloves
Materials:
- Replacement wood (2x6 or 2x8 boards)
- Joist hangers
- Lag screws
- Wood glue
- Wood sealant or stain
Step-by-Step Guide to Fixing a Sagging Deck
Step 1: Assess the Damage
Inspect your deck thoroughly to identify the areas that are sagging. Use a level to determine how much the deck is sagging and where the support is lacking.
Step 2: Remove Damaged Boards
Using a pry bar and hammer, carefully remove any damaged or rotting boards. Be cautious not to damage surrounding boards that are still in good condition.
Step 3: Reinforce the Joists
- Add Additional Joists: If the existing joists are too far apart, consider adding more joists to provide better support. Space them no more than 16 inches apart.
- Install Joist Hangers: Use joist hangers to secure the new joists in place. This will help distribute weight evenly across the deck.
Step 4: Replace the Decking
Cut new decking boards to size and secure them in place using screws. Make sure to leave a small gap between boards for drainage.
Step 5: Level the Deck
If the deck is still sagging after replacing boards, you may need to adjust the support posts. Use a level to ensure the deck is even, and make adjustments as necessary.
Step 6: Seal and Protect
Once the repairs are complete, apply a wood sealant or stain to protect the wood from moisture and UV damage. This will help prolong the life of your deck.
Tips for Maintaining Your Deck
- Regular Inspections: Check your deck for signs of wear and tear at least twice a year.
- Clean Debris: Remove leaves, dirt, and debris to prevent moisture buildup.
- Reapply Sealant: Depending on your climate, reapply sealant every 1-3 years.
