Lowering an existing deck can significantly enhance your outdoor living space, making it more accessible, safer, and visually appealing. This process involves several steps, from planning and preparation to the actual construction. Let’s delve into a comprehensive guide on how to lower an existing deck, ensuring you understand each step and its importance.
Before you begin, it’s crucial to check local building codes and obtain any necessary permits. Additionally, consult with a professional if your deck is attached to your home or if you’re unsure about any aspect of the process. Safety should always be your top priority.
Assessing Your Deck’s Current Condition
Before you start any work, assess your deck’s current condition. Check for signs of rot, warping, or structural damage. If the deck is in poor condition, it might be safer and more cost-effective to replace it rather than lower it.
Once you’ve confirmed that your deck is in good enough condition to be lowered, measure its current height. This will help you determine how much you need to lower it and whether you’ll need to adjust the footings or add support posts.
Gathering Materials and Tools
Lowering a deck requires specific tools and materials. You’ll need a circular saw, a drill, a level, a tape measure, concrete, gravel, and new lumber for the supports and footings. You may also need additional hardware like screws, bolts, and brackets.
It’s essential to choose high-quality materials that can withstand the elements and support the weight of your deck. Pressure-treated lumber is a good choice for the supports and footings, while composite or cedar materials can be used for the decking itself.
Planning the Deck’s New Height
Determine the desired height of your lowered deck. A common height for decks is 18 to 24 inches, but this can vary depending on your needs and preferences. Ensure the new height is safe and comfortable for you and your family to use.
Once you’ve decided on the new height, calculate how much you need to lower the deck. This will help you determine how much material you need to remove and whether you need to adjust the footings or add support posts.
Preparing the Deck for Lowering
Before you start cutting and removing material, prepare the deck for the work ahead. Remove any furniture, plants, or other items from the deck. If the deck is attached to your home, you may need to temporarily remove any railings or other obstructions.
Next, secure the deck to prevent it from moving during the lowering process. You can do this by driving stakes into the ground around the perimeter of the deck and attaching them to the deck frame with straps or ropes.
Removing Material from the Deck’s Frame
Using a circular saw, carefully cut away the material from the bottom of the deck’s frame. Start from one corner and work your way around the deck, cutting along the lines you’ve marked. Be sure to wear safety glasses and follow all safety guidelines when using power tools.
As you remove material, you may need to adjust the footings or add support posts to maintain the deck’s stability. If you’re lowering the deck by more than a few inches, you’ll likely need to add new footings or extend existing ones.
Adjusting or Replacing Footings
Footings are the foundation of your deck, providing support and stability. If you need to adjust or replace footings, dig holes at least 8 inches in diameter and 12 inches deep. Fill the holes with gravel to promote drainage, then pour concrete into the holes.
Allow the concrete to cure for at least 72 hours before proceeding with the next steps. Once the concrete is cured, you can attach the new or adjusted footings to the deck frame using bolts or brackets.
Lowering the Deck
With the material removed and the footings adjusted, it’s time to lower the deck. Carefully lift the deck frame and place it on blocks or temporary supports at the desired height. Ensure the deck is level and stable before proceeding.
Once the deck is at the correct height, secure it to the new footings using bolts or brackets. Make sure the connections are tight and secure to prevent the deck from moving or shifting.
Reattaching Railings and Other Features
If you removed railings or other features during the preparation process, now is the time to reattach them. Measure and cut any new railings or other features to fit the lowered deck. Ensure they are secure and meet local building codes.
You may also need to adjust any stairs leading to the deck to match the new height. Measure and cut the new treads and risers, then secure them to the stringers using screws or bolts.
Finishing Touches
With the deck lowered and secured, it’s time to add the finishing touches. Install new decking material, if necessary, and stain or seal the deck to protect it from the elements. Consider adding lighting, plants, or other decorative features to enhance your outdoor living space.
Finally, inspect your work to ensure everything is secure and stable. Check for any signs of stress or movement, and make any necessary adjustments.
Lowering an existing deck can be a rewarding project that adds value and functionality to your home. With careful planning and execution, you can create a safe, accessible, and inviting outdoor space for you and your family to enjoy. Don’t forget to step back and appreciate your hard work once the project is complete!
