How to Use a Laser Level for Deck Posts

How to Use a Laser Level for Deck Posts

Laser level is an essential tool for building a deck. It is vital to ensure all deck posts are perfectly leveled and aligned. In this step-by-step guide, we will specifically demonstrate how to use a laser level for deck post-leveling, from the initial setup to the final checks.

Step 1: Gather Your Tools and Materials

Before you begin using a laser level for deck post-leveling, make sure you have all the necessary tools and materials at hand. Here's what you'll need:

A laser level (A 360-degree laser level is recommended)
A sturdy tripod for the laser level
A carpenter's pencil or marker
Deck post brackets or connectors
Deck posts
Concrete footings (if required for your deck)
Ensuring you have all the tools and materials ready will help streamline the process.

Step 2: Marking Post Holes with Laser Level

1. Place the laser level on a stable surface.
2. Turn on the laser level and allow it to self-level.
3. Open the vertical laser line to project a straight line on the ground to position the post holes. Mark the posthole position according to the straight line. Then adjust the tripod and laser level to get all markings for the post holes.
4. Use a post-hole digger to dig all the holes for the posts, insert the posts in the holes, and fill the holes with concrete. During the process, use a level to make sure the posts are leveled.

Step 3: Establish a Reference Line

Now it's time to establish a reference line for your deck posts. This reference line will be the baseline for determining the height at which each post should be cut.
1. Place the laser level where the horizontal laser line can reach all posts.
2. Turn on the laser level to project a self-leveling horizontal line. Adjust the laser line height to the correct height you need.
3. Mark the laser line on all the posts. This mark represents the height at which the post should be cut.

Step 4: Cut the Post at The Marked Height

1. Use a saw to cut the post at the marked height. Ensure that the cut is clean and straight.
2. Recheck the post level using a level to ensure it remains perfectly level after cutting.
3. With all the deck posts cut to the correct heights, you are ready to install the joist.


In conclusion, using a laser level for deck post-leveling will improve the efficiency and provide more precise measurements. With step-by-step instructions, you can align and level all the posts easily and accurately, ensuring the stability and safety of the deck.
