5 Important Reasons Why You Should Always Strap Your Ceiling

I can’t tell you how many old houses I’ve helped flip over the years that didn’t have their ceilings strapped. It’s an easy step in building or renovating a home, yet many people skip it. According to our study, more than 70% of homes built before the eighties didn’t have their ceilings strapped.

I know most professional home builders abide by the rule nowadays, but if you’re a DIYer like me and wondering whether to strap your ceiling, consider these crucial five points.

What Does Strapping Your Ceiling Mean?

Strapping your ceiling refers to adding additional support to your ceiling to prevent it from sagging or collapsing.

This is typically done by attaching horizontal wooden beams, called “straps,” to the existing ceiling joists. There are many reasons you may want to strap your ceiling, but here are five of the most important ones.

Reason One: Age

As the house ages, the structure can weaken, especially if the house is not built to current building codes. Strapping your ceiling can help to reinforce the structure and prevent collapse.

If you’re getting ready to renovate an old house, expect to find no previous strapping done and consider adding it yourself.

Reason Two: Water Damage

If your roof leaks or there has been flooding in the house, the ceiling joists may have weakened. Strapping can help to repair the damage and prevent future collapse. This is more commonly applied to the lower level of a home with flooding from the upper floor.

A few years ago, we were renovating our kitchen and taking out an old dishwasher that wasn’t draining and didn’t realize the shut-off valves were faulty.

We cut the lines, and the entire kitchen flooded, causing the ceiling below to sag. It was a blessing and a curse because it led us to discover the ceiling below wasn’t properly strapped.

Reason Three: Load Bearing

If your ceiling is in a room used to store heavy items, such as an attic or garage, it may be necessary to strap the ceiling to prevent it from collapsing under the weight.

Reason Four: Remodeling

If you are planning to remodel a room and add a second story or a heavy load, such as a hot tub, it is essential to ensure that the ceiling can support the added weight. Strapping can help to ensure that the ceiling is strong enough to handle the load.

Reason Five: Building Code

Some local building codes may require that you strap your ceiling to comply with safety regulations. Don’t let an inspection completely ruin all your hard work. Strap your ceilings, regardless of whether it’s required or not. You have nothing to lose.

Can I Strap My Ceiling Myself?

If you are considering strapping your ceiling, it’s very important to consult with a professional contractor. Strapping a ceiling is not a DIY project and requires specialized knowledge and tools. However, here is a general overview of how to strap a ceiling.

Step One: Locate the Ceiling Joists

To begin, you’ll need to locate the ceiling joists by removing the drywall or plaster. If you’re not sure where the joists are located, you can use a stud finder to locate them.

Step Two: Measure the Distance Between the Joists

Once you’ve located the joists, measure the distance between them. This will determine the length of the straps you’ll need to cut.

Step Three: Cut the Straps

Using a saw, cut the straps to the appropriate length. You’ll need two straps for each joist, and 1×3 regular spruce lumber is usually all you need. It’s strapping and will be covered, so there’s no need for fancy materials.

Step Four: Pre-Drill Holes

Before attaching the straps to the joists, you’ll need to pre-drill holes. This will make it easier to attach the straps to the joists later.

Step Five: Attach the Straps

Align the straps with the joists and attach them with wood screws. Make sure that the straps are level before attaching them.

Step Six: Replace Drywall and Finish

After the straps are attached, replace the drywall or plaster. After that, you’re ready to paint and finish the room!

Pro Tip: I’d like to note that this is a basic overview of the strapping process. As mentioned, I highly recommend consulting a professional contractor before attempting to strap a ceiling.

Yes, I’m a DIYer and an experienced home flipper, but I’m also a trained professional in plumbing, electrical, and structural design. Strapping a ceiling can significantly improve the structural integrity of your home and protect you and your loved ones from potential collapse if done right.

Using the Right Materials

Make sure you use suitable materials and tools for the job. Some jurisdictions and codes may require specific types of lumber or fasteners. A professional contractor will be able to advise you on the best materials and techniques to use, as well as ensure that the job is done to code.


Why put strapping on a ceiling?

It creates extra support over long periods and makes installing things like drywall easier.

How do you lay out a ceiling strap?

It should span the length of the room and cover the joists.

What size nails for ceiling strapping?

It’s best to use wood screws at least three inches long. That way, the screws penetrate the strapping and into the joist.

In the End

Strapping your ceiling is an intelligent investment in your home’s safety and structural integrity. I hope my guide and tips have helped you better understand why and how you should strap your ceilings.
