Crawl Space Door Replacement

If you are getting your crawl space encapsulation done by a professional crawl space encapsulation company, you may want to consider investing money on a great crawl space door. A crawl space door is often overlooked during the encapsulation process, so we recommend you have a well-insulated, air sealed door with every crawl space encapsulation system.

Crawl space door systems

Installing a crawl space door can sometimes be an arduous task. One of the things you want to make sure of is that the wood framing of the door or the door itself is not touching the ground. You don't want water running into your newly installed crawl space encapsulation system from the outside ground during a rain storm. We have seen many homeowners and crawl space repair professionals try to build a crawl space door threshold with wood. Most of the time they use pressure treated wood. But we have found this type of install to be ineffective even if caulked properly because over time the water finds a way into the crawl space.

Crawl space door foundation

The best threshold for a crawl space door is always going to be a poured concrete threshold. We recommend the height of the crawlspace door threshold be a minimum of 6 inches above the ground, but 12 to 18 inches is better if possible. The problem with this could be that you already have a small difficult to enter crawl space access. Adding a taller threshold can make your current door even smaller. If this happens you may want to consider making the door wider or taller, so you can access your crawl space more easily.

Crawl space door framing

Make sure when you build a great crawlspace door system that you put the proper framing into place before adding the door we always recommend using pressure treated wood to build the frame. You also want to make sure that you use great weather stripping and long-lasting caulk. This will air seal the door to keep as much humidity out of the crawl space as possible. This will also make it difficult for bugs and critters to enter your crawl space especially if you properly attach the crawl space vapor barrier to the inside door frame.

Crawl space door installation

Our crawl space door installation is always a plastic style door that does not rot and is also paintable. You can use pressure treated plywood to build your own door. There are many ideas on how to build a crawl space door on the internet. Crawl space door diy (Do It Yourself) projects may take a minimum of 2 days if you need to pour a concrete threshold. The concrete must have time to cure before adding the framing.

Crawl space door insulation

Since most of our crawl spaces are insulated with a foam board we also use the same foam board on our crawl space door insulation. Insulated crawl space doors are vital to a crawl space encapsulation system. Depending on your climate and your local building code the R-value of the crawl space door insulation can vary but make sure you choose something that is easy to install and won’t be a nest for bugs and small rodents.

Crawl space door replacement

So, when should you consider replacing your crawl space door? That's easy whenever it looks bad or is rotting or is not well insulated and air sealed. If you are investing money into fixing your crawl space through crawl space encapsulation we recommend you replace the crawl space door. This will ensure the crawl space encapsulation system is done properly and make your home look even nicer with a brand new insulated crawl space door system.
