If you’re wondering whether door sweeps or door bottoms are better for your home, these terms actually refer to the same door part. Although they’re a small part of your door, the sweep and bottom keep your home sealed against the elements. Here’s a breakdown of the types, pros and cons, and costs to remember when adding this part to your door.
What’s a Door Sweep vs. Door Bottom?
You can use the term door sweep or door bottom to refer to the same part of a door. As the name suggests, it attaches to the bottom of the door to keep elements like wind and rain out of your entryway. One variation of this part has bristles, which is likely where the name “door sweep” comes from.
A door bottom is a key part of your door’s seal against weather, moisture, and insects. Installing a sweep or bottom will prevent cold drafts and increase your home’s energy efficiency.
It’s helpful to note that some manufacturers refer to certain types of door sweeps and bottoms by one of the two names. If you’re shopping for one, it’s better to pay attention to the type of sweep or bottom rather than what it’s called. If you hire a door repair pro to help you install a door sweep, they can also help you choose the best option for your door.
Types of Door Sweeps and Door Bottoms
There are several types of door sweeps and bottoms, with the strip and bristle models being the most common.
Strip: Strip door sweeps and bottoms have a metal or plastic mount with a vinyl strip. Installation for peel-and-stick sweeps and bottoms takes a few minutes, while a more long-lasting screw-on mount only takes ten minutes.
Bristle: Bristle options have a metal or plastic mount with nylon or PVC bristles. They don’t create a seal as tight as the strip types and can allow some moisture and air to enter.
Under-Door: These are U-shaped on the top and snap onto the bottom of the door. They have two to five vinyl fins, which create a better seal at the bottom of the door than the strip and bristle types.
Automatic: Automatic door sweeps and bottoms are also called spring-action sweeps. Automatic ones move up when the door is open and back down when the door is closed. The installation process is more complex for this type, requiring a router and some carpentry skills.
Pros and Cons of Door Sweeps and Bottoms

The pros of door sweeps and bottoms outnumber the cons. The advantages include lower heating and cooling bills and preventing rain from seeping beneath the door during storms. They help keep your home nice and cozy in the winter by preventing unpleasant, cold drafts from blowing in from under the door.
Installing a door sweep and bottom has no disadvantages, although there are some cons for specific types. For example, moisture can get stuck between under-door sweeps and wood doors, potentially causing warping and wood rot in extreme cases. To avoid this, paint the bottom of the door before installing your new door sweep.
Another sweep and bottom type to look out for is the peel-and-stick ones. These are easy to install since you don’t need any tools, but they don’t last as long as screw-on mounts and can fall off unexpectedly. Some models have a powerful adhesive that makes it almost impossible to readjust them if you accidentally install them crooked.

Jeremiah did an awesome job cleaning 28 windows inside and out! He was fast, efficient and now I have a beautiful view again. This was a Groupon for $139 for 20 windows, but I had 28 windows/doors cleaned, so there was an extra $6 per window. Totally worth it.
