Methods: How to Fix a Metal Door That Rubs at the Bottom

Method 1: Using Insulation

This is perhaps the most common method for fixing a metal door that rubs at the bottom. Insulating your door will protect it against cold and hot temperatures, as well as moisture from rain, snow, and other harsh weather conditions.

To begin with this repair process, you will need to purchase wood shims or 4 to 6 inches of wood. Next, you need to find a way to hang the insulation on the door to stay in place. After this, get out your keyhole saw and cut some small holes in between the metal slats. Once this is done, then slide the wood shims or 4 to 6 inches of wood through each hole and then install the insulation on top of it.

Shimming is a quick and inexpensive method for fixing metal doors, and you can choose to use this method or one of the other methods mentioned here. If shimming doesn’t work, then try out some of the others!

Method 2: Adding Weather Stripping

There are many different types of weather stripping that you can use to fix a metal door that rubs at the bottom. Each one serves a different purpose and comes in many different materials. The first type of weatherstripping is called U-channel, which is very thin but durable enough to serve its purpose! This material often comes in pre-cut pieces and is a good choice for fixing a metal door.

Another option is weatherstripping made out of cork, also known as Cork bark. This type of weatherstripping is quite durable but may need an extra layer added on top of it to be more effective. If you want to find the best weather stripping for your door, do some research and read online reviews. You can even test them out yourself if you’d like!

A good rule of thumb when installing weather stripping to fix a metal door that rubs at the bottom is to measure how long it will be in advance. This will help minimize any mistakes made and will also make the actual installation process much easier.

Method 3: Adding Spacing Pieces

Another excellent method for fixing a metal door is by adding spacing pieces. These pieces help separate and support both the top and bottom of your door at all times, which prevents it from rubbing against or damaging your door frame.

These spacing pieces can be purchased at any home improvement store and are very simple to install. To do this, you will need your metal lubricant! Put the lubricant on just the bottom of your door and then slide in the spacing pieces like you would a shelf. The thickness of these pieces needs to be equal to or greater than the space between the frame and your door.

If you don’t want to purchase spacing pieces, there are other options available to you. For example, you can create your own spacers out of wood or metal and use these in place of the pre-made ones for sale. Another option is to shim up your door by adding extra pieces of wood, metal, or nails to elevate the bottom of it slightly above your door frame.

Method 4: Installing a Threshold

Installing a threshold is another excellent method for how to fix a metal door that rubs at the bottom. A good threshold will be durable, sturdy, and long-lasting, so make sure you choose one of these qualities when shopping for your threshold.

Once the threshold is installed, then you won’t have to worry about your door rubbing against the bottom of your door frame. This method also provides some extra protection against mice and other pests that may otherwise damage your home.

Method 5: Applying Caulk Around the Edge of the Door’s Frame

Another excellent option for fixing a metal door is applying caulk around the edge of your door’s frame. This will fill in any gaps between your doorway and the floor or ground below, thereby preventing the door from rubbing against it and causing damage!

However, if you would like to use caulk to fix a metal door that rubs at the bottom, then make sure you choose a mildew-resistant type of caulking. This will prevent any mold from forming in the future and ensure that your repairs stay firm for as long as possible!  This option is simple yet effective and is another great method for fixing a metal door that rubs at the bottom.

If you are having trouble applying caulk around the edges, consult your local hardware store or home improvement center! They will be more than happy to tell you what’s best and help you narrow down your options.

Method 6: Adding Rubber-like Strips

A straightforward method for fixing the metal door is by adding rubber-like strips. These can be purchased from your local hardware store or home improvement center and come in many different colors, so you can find one that matches your door!  

These rubber-like strips are easy to install and do not require any tools to be put in place. Also, if your door rubs against the ground or flooring below it often, this method may help you fix the problem!  This option is one of the easiest methods for fixing a metal door that rubs at the bottom.

The information above should be enough to help you out when fixing a metal door that rubs at the bottom. Each of the methods mentioned above is relatively easy to complete, and you should be able to get your door fixed in no time!

Things To Consider Before Using Lubricant on Metal Door

  • Do not use waxes, oils, or petroleum jelly to lubricate your door hinges. These are sticky and may attract dust or dirt, which causes them to become clogged. If your home has a lot of dust, you may need to occasionally apply a light coat of silicone lubricant (like WD-40) to the hinges. The oil in the lubricant helps attract and hold dust away from the hinge.
  • Always clean your door off thoroughly before applying any metal lubricant. If there is dust or grime on the frame or hinges, then this can negatively affect the life expectancy of the oil you’re using. Always make sure that you’re using the right lubricant for your door.
    This is a very important point and can be very confusing as there are many different types of lubricants. You should only use a lubricant made specifically for steel doors or aluminum doors; if you don’t, you’ll end up with a sticky mess on your hands.
  • Be sure to purchase metal lubricants made specifically for door hinges and not some other metal object or machine; otherwise, they may be harmful and actually cause more damage than good! If you’re finding your door hinges are wearing out quickly, or if they have become loose, get them fixed immediately.
  • Rubbish metal products will not work with door hinges. As a result, they may fall out or cause harm to the structure of your door or frame. The long-term use of these products is also not recommended.
  • Metal lubricants are typically clear, so they blend well into most doors and frames. However, if you want a colored option available for you, then be sure to choose one that is clear but has a tint similar to the color of your door. Many people also like to use a colored lubricant in their high-traffic areas, like the doorknob.
  • Always allow metal lubricant to dry before using your door again. If you don’t, then it will cause a buildup on your hinges and other hardware that may deter or even prevent them from properly functioning in the future!
Always Allow Metal Lubricant
  • You can use any metal lubricant on your hinges, but be sure to follow the directions that come with the product you choose. If you do not properly apply metal lubricant to a set of door hinges, then it will not work and may actually cause more harm than good! If you are using a metal lubricant, then you have to apply it in small amounts and rub it into the hinge with your fingers. Otherwise, you can cause the hinge to rust!
  • If you have difficulty opening or closing your door after applying metal lubricant, then consult your local hardware store or home improvement center. They will be able to tell you what type of lubricant is best and help you apply it properly so that your door works well again!
