surface mounted to the bottom of the door. Ideally, the sweep should be installed so that comes in contact with the bevel on the threshold but

L-Shaped and Surface Mount Sweeps

L-Shaped and Surface Mount Sweeps. Sun Mountain's L-shaped and surface mount sweeps include a drip cap to direct water away from the door. L- shaped sweeps are provided on all 1-3/4″ thick exterior doors. Surface mount sweeps are supplied in all 2-1/4″ thick or thicker exterior doors. If installed on-site, Sun Mountain recommends sealing the top edge of the sweep with a bead of silicone at the time of installation, to prevent moisture from seeping between the sweep and the door.


The U-Shaped door sweeps are usually made out of silicon and aluminum because of their durability. Silicon is the main insulator there, and the aluminum is the carrier for the silicon. Their shape enables them to simply slide underneath the door and can be adjusted so that it covers the gap to the threshold.

U-Shaped door sweeps

Installing a door sweep is relatively straight forward and can be erected using simple tools and less effort.

Select The Right Type

Types of door sweeps

Door sweeps (bottom) can be used in a variety of homes, even rented houses. The most common door sweeps for exterior doors are standard, automatic, selfs-stick, and draft door weatherproofing. Choosing the right door sweeps for exterior doors is relatively easy when you know the specifics and follow the step by step procedure.

Standard Sweep

Select The Right Type door sweeps

Standard door sweeps have weatherstripping attached to a heavy-duty aluminum carrier. The weatherstripping seals gaps from 1/2 to 3/4 inches. It is ideal for sweeping over a tile or hardwood floor. These types of door bottom sweeps are installed by being screwed into a steel or wooden door. The most common size is a 36-inch door sweep, but you may need a 42-inch door sweep. A standard aluminum door sweep comes with vinyl weatherstripping and is easy to install as it typically comes with nails that can be screwed into a wood or metal door.

Automatic door sweep

Automatic door sweep
There are a few styles of automatic door sweep which remove the problem of drag on flooring or carpets. These sweeps are slightly more expensive and can be more challenging to install. They can also require a small pause after unlatching the door so that they are correctly retracted. An automatic door bottom is adjustable and often provides a better seal. An automatic door sweep is bulkier than a door sweep due to what is on the inside. When the door is opened, the activator “button” releases. The seal material is pulled up inside the door bottom, which allows the door to swing open and closed without the seal material dragging along the floor. Suitable for renters or homeowners not interested in making any permanent changes to doors.

Removing Existing Door Sweep

Removing Existing Door Sweep

When you want to remove and replace a door sweep, probably because the existing one has worn out, replacing a bottom seal on a door isn't difficult. You do not have to remove your door off the hinges to install to remove or replace a door sweep. However, if the door sweep is glued or nailed onto the button door, you will have to get the door off the hinges. The door could be weighty, and you might need to employ extra hands to assist you, so you don't hurt yourself.

Step 1:Remove the door

To get to the glued or nailed bottom door sleep, there is no way out of it unless you remove your door off the hinges.

Step 2: Place it on a Stand

Take it to your garage and get a stand to relax your door.

Step 3: Get a Scraper

You don't need a unique tool; a scraper will do just fine. Hold tightly to the edge of the door while using the scraper to remove the glued door sweep.

What you'll need?

You only need essential tools to install a door sweep. These are;  pencil, drill, saw, putty knife, hammer, metal-cutting scissors, and measuring tape.

To install a door sleep, you need to ensure you're purchasing the right door sweep with proper screws for your particular door. It is advisable to buy extra self-tapping screws as not all pre-packaged door sweeps come with them.

Metal Door Bottom Sweep

Metal Door Bottom Sweep

Its a type of door sweep that blocks air and sound with just a single metal strip. It is to be noted that you can only install this particular type on the side that swings inward. To install this door sweep, you can either you screw, glue, or nail to fasten it securely to the door. Below are the steps you should follow to install a metal strip door sweep.

Step 1: Take Measurement of your door bottom

Measure the width of your door then buy a door sweep that is at least as big as your door. With the door closed, measure the bottom of the door and transfer your marks onto the door sweep.

Step 2: Cut the Sweep

Cut the door sweep to the appropriate door bottom size using your heavy-duty tin snips or a hack saw cut the door sweep to fit the bottom of the door.

Step 3: Mark and drill holes

Most door sweeps come with pre-drilled holes, so you just need to line up the sweep with the drilled holes. However, some might not have been pre-drilled, and from time to time, these holes are in the wrong place, and those extra self-tapping screws you bought will come in handy. After cutting the door bottom sweep to the right measured specification, you will have to mark and drill pilot holes through which screw will be inserted to tighten the door sweep to the bottom of the door.

Step 4: Ensure contact  with the floor

Place your door sweep against the bottom of the door, ensuring the rubber seal or nylon brushes come in contact with the threshold or floor.

Step 5: Loosely attach door sweep & adjust as necessary

The trick is to install the door sweep, so it contacts the threshold or floor evenly but is not too tight that it binds the door and prevents it from closing.  This is where the oval slots [adjustment slots] come in handy.

Step 6: Adjust the Door Sweep

Install the screws in the middle of the oval slot, but don't over tighten them. Positioning the screws in the middle of the space allows you to micro-adjust the sweep up or down. Try opening and closing the door a few times to check the fit.

Step 7: Fasten securely to the bottom of your door.

This is the stage where you finish the job by tightening the screws. Once the sweep is secured correctly, then close the door to ensure it is a good fit and that there is no draft coming in underneath the door. If it is not a good fit, make the adjustments to ensure it is a good fit.

Slide-on Door Sweep

Slide-on Door Sweep

Installing a side door sweep is slightly different from how you will install a Metal door sweep. Also called U-Shaped door sweep. It's a type of sweep that extends and covers both sides of the door. Installation of this type is relatively easy as you only have to slide the door sweep under the bottom of your door to install.

Step 1: Measure the Width of Your Door

You need to ensure your door sweep fits the exact width of the bottom of your door. If it's too big, then measure and make the appropriate markups for cutting.

Step 2: Cut to Size

At this stage, you should get a saw to cut your door sweep to the correct size.

Step 3: Slip It On

Now all you need to do is slip underneath your door.  The design of the door sweep uses tension to keep it in place.

Step 4: Adjust Accordingly

You can make the door sweep fit better by hammering it down lightly with a putty knife until it meets the threshold.  This will create the airtight seal needed to prevent air and sound from infiltrating your room.
