How to Laser Level a Ceiling


When installing a ceiling, particularly a drop ceiling, there is no easier way to make sure you have a level product than to use a laser level. When it comes to ceilings, a laser level can cut hours off installation for those who still use the old traditional levels. However, where can you benefit from a laser level in a ceiling installation?

Where to Place the Laser Level When Installing a Ceiling

  • Wall Angles – For drop ceilings, installing the wall angles is often the most frustrating bit. However, the fastest way to install a wall angle is to mount the laser so that it runs below the angle, and then fasten it. You get a level angle, every time.
  • Main Runners – Mount the laser level at one end of the main runner and adjust the beam so that runs just below the grid of a drop ceiling. On any type of ceiling, this will help check for any slopes created during the installation and make sure everything is all nice and level.
  • Building Ceiling Drops – By installing the laser at the bottom of the drop, you can install your lower angle pieces and cut all your tees to the beam of the laser which will create a perfect ceiling drop.
  • Installing Support Wires – When it comes to supporting your grid system, if you measure off the walls of both ends of the room and set the laser level on the floor, the beam will project on the floor joints so you won’t have to measure every single wire, every single time, opening up room for error.

Rotary Laser or Continuous Line Laser

While rotary lasers are pretty standard for outdoor jobs, do you need them for installing ceilings or can you switch out for your line laser? Honestly, the type of laser you want to use depends on the size of the room. If you are installing a ceiling in a 1,000 or more square feet room, you will need the power of a rotary laser. It is not so much that you will need its rotating beam function, though it does help, you need its power. Line laser levels may go a couple of hundred feet, but rotary lasers pack the power to be seen at 1,000+ feet, making them necessary when doing large ceiling jobs.

However, if you are working in a small room and installing a ceiling, your standard line laser level will do the job just fine. It is a less bulky, lighter weight, and more affordable alternative to a rotary laser, However, if you are trying to make the choice between one or the other, it is best to think not just about your current job installing a ceiling, but any future jobs that you may need it for as well.
