Garages are integral parts of homes and many commercial properties, constructed with varying garage door types. If you are concerned about weather-stripping your garage entrance, you should consider fixing a door bottom seal.
Garage door bottom seals come in various shapes and sizes made from different materials. Each type of garage door bottom seal has its advantages and disadvantages, which homeowners should consider to ensure that they select the right one for their parking space.
While some are quite simple, you may find others pretty complex. But, only the right one can help keep out water, bugs, grass, and dirt from entering your garage. This article discusses the different types of garage door seals and their features. So, read on to reach the right one for your garage set up.
Different Types of Garage Door Bottom Seals
Some homeowners tend to underestimate the importance of garage seals to cut costs. Nevertheless, it is crucial to weather-seal your parking space against damaging elements such as heavy rain, wind, hail, and snow.
Weatherstripping is an excellent way to save you the stress of regular cleaning and likely damages that could ruin or leave awful stains on garage floors. These products are attached to the bottom edge of garage doors.
It emerges as a long flexible strip of vinyl or rubber that compresses when you shut the door, closing the gap between the door and floor.
Some common types of garage door bottom seals include:
The circular-shaped bottom is a peculiar feature of this door bottom seal, and it has a sizable T-shape at its top. It is one of the best garage door bottom seals useful for single-channel retainers. Hence, it allows the seal to spread out and push upwards on uneven cemented floors.
Beaded garage door bottom seals come in handy for double channel retainers, having circular grooves. The two sides of the strip are bent, facing upwards, and fit into the circular grooves. You can find the beads averting water flow into the garage from beneath the seal.
T-type garage door bottom seals seem pretty simple, having an inverted “T,” and are used alongside single-channel retainers.
The J-Type Bottom Seal
The J-type garage door bottom seal appears similar to the T-shaped type but creates two letters (J and S) on both sides when the garage door closes.
A less complex slanted-edged seal with a “strip” design that conceals the door front and the floor is commonly employed for wooden garage doors – roofing nails (usually galvanized or aluminum) are employed for their installation.
At the bottom of most garage doors made from metal is an aluminum channel with a U-shaped rubber gasket, also known as an astragal or T-style seal. You would find the gasket slotting in two small tracks on the channel during installation.
The best thing about U-shaped gaskets, aside from their ease of installation, is that they come in various sizes to close spaces of varying measurements.
Irrespective of the material used for constructing the garage door bottom seal, you can find it degrading over time and becoming less effective. If you already have one installed, you can start planning for a “garage door bottom seal replacement” when daylight is visible from the door’s bottom while shut closed.
Other Options for Weather-Sealing Garage Door
Garage Door Threshold Seal
The threshold seal is installed in many garages, attached to the parking space floor. You can find these thresholds standing alone or used alongside another door seal. If you find your property sited in a manner that lets in surface water into the garage, then you should consider fixing the threshold seal.
This piece helps prevent surface water flow into the garage from a steep driveway. One downside to thresholds is that they also prevent water from flowing out of the garage; hence, cleaning processes may seem challenging.
Since it helps fill the space between the door’s bottom and the floor, you may find it tasking to hose out the garage or sweep out dirt. Nevertheless, you can find a way out of such inconvenience and install a durable vinyl threshold for the garage.
Garage Door Stop Weather-stripping
If the sides and top of the garage door have spaces, it would be a sure entry for rain and wind damaging items stored inside the garage. Not to worry, you can prevent this problem, using either a vinyl or rubber weather-stripping material on the door to stop molding.
While most properties have such items in place to prevent external elements from gaining entry into garages, you may find some others lacking. So, if your garage door lacks weather-stripping or the one present is old/damaged that it no longer seals against the door, you need to get one right away.
New weatherstrips are available in rolls; cut to length using a scissor or utility knife. You can fasten them in place using nails or screws. You can create a good seal by pushing the weather-strip door-side rim against the door.
Garage Door Panel Weatherstripping
There are often garage door panels with spaces that expose the parking space to several elements. Thus, most homeowners try to install garage door panel weatherstrips. This piece has a V-shape design and helps conceal those exposed gaps lying between each door panel when installed.
You can check any hardware store if you want to get one for your garage door. These items are sold in rolls and have adhesives that make them easy to fix in place. The simple trick is to stick it to the edges of each panel, either at the bottom or top.
Decrepit wooden doors with flat-edged panels would often have spaces that allow air intrusion. With this weatherstrip, you can create an effective seal as the panels compress it when the door closes.
Vinyl Door Stop
For doors that have old, rotten, or damaged door stops, it is best to consider installing a new door stop molding featured with weatherstripping. This specialty is a fantastic solution normally constructed of vinyl material.
It consists of a single piece with a wood-look molding strip and a flexible weather-seal flange. You can mount it with stainless steel or galvanized siding nails. Since this piece cuts readily with a saw, you can install it with much ease.
It’s usually better to place the top molding first and then overlap its ends with the side stops. Start by placing each piece parallel to the door face. Then, push in the molding in the direction of the door.
Doing so would make the weatherstrip flange to get squashed against the door. Move further to nail the molding to the door jamb.
