Frequently Asked Questions

What Kind of Wood Should I Use for a Crawl Space Door?

You can’t just use any wood for an external crawl space door. Because the door is functional, it is vital that it can withstand quite a bit of use and force. You don’t want to build a door only to have it break after a few months.

Plus, external doors must withstand the wind and rain. Therefore, the wood has to be weatherproofed and durable. Pressure-treated wood is the best to use on your crawl space door.

What Can I Use for a Crawl Space Door?

Typically, most crawl space doors are made using pressure-treated wood. We highly recommend carefully choosing a wood that can be utilized outside without rotting or getting eaten by bugs.

However, some crawl space doors are made of metal. Of course, metal often lasts longer, but it can be harder to work with. Plus, if the metal isn’t cared for well, it can rust. Therefore, metal isn’t necessarily the better option for all crawl space doors.

Should I Insulate a Crawl Space Door?

An insulated door will keep your house at the correct temperature and reduce energy costs. However, you don’t need to insulate all crawl space doors. If your home’s crawl space isn’t insulated for one reason or another, your crawl space door may not need to be insulated, either.

Typically, this is considered an “extra” step. However, it can help reduce your energy costs. Therefore, we recommend attempting to insulate your crawl space door when possible. It may take a little bit more work, but it is worth it in the end.

What is the Standard Size for a Crawl Space Door?

To ensure that the crawl space is accessible to most people, the door needs to be at least 18×24 inches. However, you’ll need to measure your crawl space to ensure you have the proper measurements.

Building a crawl space door isn’t difficult. However, the materials you use are vital. You don’t want to use wood that will decay or rot after only a year or two. For that reason, take time to choose your materials so that you don’t have to make a new door every few months.

We’ve listed two plans above to help you construct a crawl space door. Luckily, building a door isn’t very difficult in the least.
