Tools Needed for Checking

Before you begin the process of checking for square, level, and plumb on your decking project, it’s important to gather the necessary tools. These tools will help you accurately measure and assess the alignment of various components. Here are the essential tools you will need:

1. Measuring Tape: A measuring tape is crucial for taking accurate measurements of distances between points and ensuring symmetry.
2. Carpenter’s Square: Also known as a framing square, a carpenter’s square is a helpful tool for checking the squareness of corners and angles. It consists of a long arm and a shorter arm that are at a 90-degree angle to each other.
3. Level: A level is used to determine whether a surface or object is perfectly horizontal or vertical. A 2-foot or 4-foot level is recommended for most decking projects.
4. Plumb Bob or Line Level: A plumb bob or line level is used to check vertical alignment. It helps you ensure that posts and railings are perfectly upright.
5. String or Mason’s Line: String or mason’s line is useful for creating guide lines that you can use during the checking process.
6. Pencil or Chalk Line: These tools will allow you to mark your measurements and guidelines on the decking material.
7. Power Drill or Screwdriver: You may need these tools to adjust or secure components as you make adjustments to achieve square, level, and plumb.
8. Safety Gear: Don’t forget to wear safety glasses, gloves, and any other necessary protective equipment while working on your deck.

By having these tools readily available, you will be well-prepared to accurately measure and assess the squareness, levelness, and plumbness of your decking project.

Step 1: Checking for Square

The first step in ensuring that your deck is square involves checking the corners and angles to ensure they are perfectly 90 degrees. Here’s how to do it:

1. Start by marking a reference line along the outside edge of one of the deck boards. This line will serve as a guide for measuring and checking the squareness of the deck.
2. Measure diagonally from one corner of the deck to the opposite corner. Use a measuring tape and take note of the measurement.
3. Next, measure the other diagonal from the opposite corners of the deck and record the measurement.
4. If the two diagonal measurements are equal, your deck is square. If they differ, your deck is not square, and adjustments need to be made.
5. To square the deck, gently tap the corners that need adjustment with a hammer or rubber mallet to align them properly. A carpenter’s square can be used to verify the 90-degree angles.
6. Continue checking for squareness by measuring and adjusting the other corners as necessary. Remember to use the reference line you marked earlier to guide your measurements.
7. Once all corners are square, secure the deck boards and framing materials in place using screws or nails.

Checking for square is a crucial step to ensure the stability and aesthetic appeal of your deck. Taking the time to make adjustments and ensure that all corners are perfectly 90 degrees will result in a well-built and visually pleasing end product.

Use a carpenter’s square to check for square, a level to check for level, and a plumb bob to check for plumb on your decking. This will ensure a sturdy and well-built deck.

Step 2: Checking for Level

Checking for level is an important step in ensuring that your deck surface is flat and even. Here’s how to check for level:

1. Start by selecting a reference point on your deck. This can be a post, a corner, or any fixed point that you can easily measure from.
2. Place a level on top of the reference point and ensure that it is fully in contact with the surface.
3. While keeping the level in place, observe the bubble in the level. If the bubble is centered between the two lines, it means that the surface is level. If the bubble is off-center, adjustments are needed.
4. To adjust for levelness, use shims or adjust the supporting posts or beams until the bubble is centered.
5. Continue checking the levelness of the rest of the deck surface by moving the level to different areas and repeating the process.
6. Make any necessary adjustments to ensure that the entire deck surface is level. This may involve adding or removing shims, adjusting post heights, or sanding down high spots.
7. Once the deck surface is level, secure the decking material in place, ensuring that it remains level during installation.

Checking for level is essential to prevent water pooling, uneven surfaces, and potential tripping hazards on your deck. A level deck will also give a polished and professional appearance to your outdoor space.

Note: If your deck has multiple levels or tiers, it is important to check for levelness on each individual level, as well as the overall deck structure.

Step 3: Checking for Plumb

Checking for plumb ensures that your posts and railings are perfectly vertical, providing stability and a polished look to your deck. Here’s how to check for plumb:

1. Select a reference post or railing to begin the plumb checking process.
2. Hold a plumb bob or line level against the reference post or railing, allowing it to hang freely.
3. Observe the position of the bob or bubble. If it aligns perfectly with the center of the marking on the level, the post or railing is plumb. If not, adjustments are needed.
4. To adjust for plumbness, gently tap or nudge the post or railing until the bob or bubble aligns with the center marking.
5. Continue checking the plumbness of the remaining posts and railings using the same method.
6. Make any necessary adjustments to ensure that all posts and railings are plumb, using a level or plumb bob as a guide.
7. Once all posts and railings are plumb, secure them in place with appropriate brackets, screws, or connectors.

Checking for plumb ensures the overall stability and safety of your deck’s structural components. Properly aligned posts and railings not only enhance the visual appeal but also provide a secure and reliable framework for your deck.

Remember to periodically recheck the plumbness of your deck’s posts and railings, especially after any significant changes or movements.

Common Issues and Troubleshooting

During the process of checking for square, level, and plumb on your decking project, you may encounter some common issues. Here are a few of them, along with suggested troubleshooting solutions:

1. Uneven or warped deck boards: If you notice that your deck boards are uneven or warped, it can impact the overall levelness of the surface. In this case, consider replacing the affected boards or using shims to create a level surface.
2. Inaccurate measurements: It’s important to ensure accurate measurements when checking for squareness, levelness, and plumb. Double-check your measurements and use high-quality measuring tools to avoid any discrepancies or errors.
