The sweeps can be further expanded into specific types available on the market today including automatic, L-shaped, wrap-around, self-adhesive, slide-on door sweeps.

Let’s discuss each of these models to help you decide which one will work for you.

Strip door sweep

This is one of the most preferred door sweeps by homeowners due to its high effectiveness and convenience score. It is incredibly easy to store and takes up less floor space.

Replacing it is also hassle-free when you want to switch to a new, more effective model.

You’ll find some of the strip door sweeps featuring an adhesive backing. This simply enables them to stick to any side of the door, ensuring a hassle-free installation.

Other strip sweeps come equipped with rigid plastic or metal installation guides that you fasten to the bottom end of your door.

Also known as a self-stick, this door comes with an adhesive mechanism, so you don’t need to drill any holes to set it in place. Instead, you simply peel off the paper on its back and then press it in place.

This type of door sweep is best suited for homeowners and renters who don’t want to install permanent door sweeps to their doors.

The sweeps are usually made of flexible plastic strips and you can install them on wood as well as metal doors.

This door sweep has a U-shape design which enables it to wrap around your door to form tight seal against outside elements that you want to block from entering your home.

Wrap-around door sweep

Wrap-around door sweeps are also easy to install but you’ll need to drill new holes into your door for you to correctly set it in place. Most of these sweep models are also paintable to help you match them to the color of the door you attach them to.

Automatic door sweep

As its name suggests, this type of door sweep is automatic—meaning the seal automatically drops to form a barrier whenever you close the door. It automatically rises when you open the door and drops when you close to form a seal against those outside elements.

The advantage of choosing an automatic door bottom over a standard one is that it assures you of a tight seal.

The rubber pushes down onto the floor, preventing the seal from dragging along the floor when closing. This way, it protects the floor surface and prevents the seal from quickly wearing out.

Unlike a regular sweep, the automatic model also features a larger width which allows for a thicker seal and better protection against the undesired elements.

Installing it is also easy as you simply need to attach it to your door using screws.

Snap-In door sweep

You’ll find this type of sweep in varying designs and even heights to help you choose the most suitable one for your unique needs. Most of them feature a single or double kerf cut in the door bottom to allow the sweep to easily and securely lock into place.

Which side of the door do you install a door sweep? Inside or outside?

The side on which you install your door sweep will mainly depend on the type of door you’re dealing with.

You should install a door sweep on the inside of the door if your door is designed to swing into the house. If your door swings outside, you should install your door sweep on the outside bottom edge of the door.

Whatever type of door you’re dealing with, you should keep in mind that a door sweep is intended for installation at the bottom of the door to create a seal between the threshold of the bottom of your door and the rubber of the sweep.

Should a door sweep touch the floor?

No. The sweep should be installed such that it comes into contact with a bevel on your door threshold without touching the flooring material, whether it’s carpet, tile, etc.

If you let your door sweep touch the floor, it will end up making the door difficult to use. That is, it will create friction with the floor which will give you a dragging effect when opening or closing your door.

Besides making your door hard to work with, this friction might also cause your door sweep to catch your carpet, laminate, hardwood flooring, or ceramic tiles and cause damage or scratches to it. In the long run, it will wear down your flooring and force you to replace it.

Should a door sweep touch the floor

Also, the sweep itself will wear faster due to the friction effect and force you to replace it with a new one before its expected lifespan is over.

But you shouldn’t place the sweep too high above the floor or it’ll create a gap that easily lets in the very elements that you’re trying to keep out and it will not be serving its purpose.
