Easy Gable Vent Install in a Shed

Hi guys! I’m back with another DIY project from that big Kids Playhouse Build I’ve been working on.

Last week, I shared how to build a small step ladder from 2x4’s. This week, I have the easy steps for a DIY Gable Vent Installation in a shed wall.

Gable Vents are great. They allow air to flow through your shed or playhouse without letting rain in.

I am putting 2 vinyl gable vents on opposite walls of the playhouse. This will let the air flow across the playhouse, helping it stay cooler in our hot Texas summers.

Since this is a playhouse and not just a shed, I also have a few big windows and doors that will always be open so that my kids aren’t at risk of being in a hot, closed building.

How to Install a Shed Gable Vent

Keep scrolling for the written steps. But, I always think it’s easier to understand a project if I can see someone doing it.

Here’s a quick step by step video walk through of how to install a Gable Vent in a shed wall, barn, playhouse, or tiny house.

Easy DIY Gable Vent Installation Steps

Please Note: The Royal brand Vinyl Gable Vent I bought at Lowe’s has a front and back piece that snaps together. It is designed for a 1 1/4″ thick wall. The 1x4 trim I used is 3/4″ thick and the siding on my shed is 1/2″ thick.

Step One

Use your vinyl gable vent and a pencil to mark out the hole for your gable vent in the shed wall. Make sure it’s square and level before cutting.

Also, make sure that there aren’t any framing studs behind the hole you just marked. If you cut into the framing, you will need to add more framing around the vent to support the roof.

After marking my opening with a pencil, I used a saw to cut out the siding.

Step Two

Cut your opening. I started with my Circular Saw, cutting the 4 sides. Then I used my jigsaw to cut the corners.

BUT, if you can’t safely hold your circular saw, you can use your jigsaw to cut the whole opening. Then, test that the vent fits into the opening before adding the trim.

Step Three

Cut your pressure-treated 1x4, or similar trim, to frame the new opening. I used exterior-grade heavy duty construction adhesive to install the trim.

Again, make sure everything is square and level. Then let the adhesive dry before moving on to the next step in your to install a Shed Gable Vent.

Step Four

Once the adhesive is dry, use an exterior grade caulk and exterior paint to finish off the trim.

It’s easier to caulk and paint the opening before installing the front of the vent. Make sure the caulk dries before painting it.

Here’s what the back of the gable vent looks like from inside the playhouse.

Step Five

While the caulk or the paint is drying, you can install the back or inside of the gable vent, from inside the shed or barn.

I used 1″ – #8 self tapping screws to screw the back of the vent into place. I will say that the instructions say to use nails, but they don’t mention where to put them or how many to use.

So, I decided to use screws to avoid hammering hard against the inside of my siding.

Step Six

Once the trim is caulked, painted, and dry; press the front of the vent into the back until it’s attached.

Then, to finish off your Barn or Shed Wall Gable Vent Installation, use the caulk again to seal around the outside of the gable vent. You can see me doing each of these steps in the how-to video above.
