How to Install an RV Access Door Hatch
RV hatch doors can be very different from each other, so it is important to find the right model and fit for your new door. Since RV doors are rarely made to a standard size, replacing them can unfortunately be very expensive. A new door can run between $400 and $500 depending on which features are included. In order to do the job properly, be sure to have the right tools and to follow the directions in the correct order.
Step 1 - Remove the Old Door
Remove all screws and/or bolts from the old door, and pull it out. Remove the frame as well. Clean all remaining caulk and putty tape from the area.
Step 2 - Order a New Door
Now that there is a hole where your old RV door was, measure it. These will be the dimensions for your new door. Remember that your new door will come with a frame, so do not keep the old one in there. Decide which kind of new door you want with regard to your own preference for color and texture, what type of lock it should have, etc. Do not leave the new wrapped door in direct sunlight as this may be damaging.
Step 3 - Apply Putty To the Door Frame
Now that you ordered your door and it has arrived, it is now time to install it. First, put at least one layer of putty tape around the door frame. In addition to providing insulation, the putty will prevent damage to the frame. A damaged door frame might give you problems with the proper fit of the door.
Step 4 - Install the New Door
Place the new door on the hole and secure it with nuts and bolts with your socket wrench. The nuts and bolts go in holes in the new door. You might need to make new holes in your RV if the new holes do not match up with the old ones. With a plastic scraper or screwdriver, scrape away any excess putty tape sticking out from the door.
Step 5 - Maintain Your New Door Properly
You have now finished installing your new RV hatch. In order to get the most mileage out of your new door, remember to take care of it properly: adjust the striker plate and bolt so that the door opens and closes as smoothly as possible. Lubricate the key cylinder on your lock at least annually. Also lubricate the hinges on your door, and wash and clean the fiberglass skin periodically. If too much dust and dirt accumulates on the skin, and the door is exposed to sunlight and wind, this may physically and chemically damage the door. Remember that replacing just the skin of the door can be nearly as expensive as replacing the entire thing.
