If you have an attached garage, pests may even find an entry point to the rest of your home. Wind and water are leaking through: Gaps in your garage door can let the elements inside. Moisture from rain and snow may reach your storage area and damage the structure of your garage over time.
Light coming through the top and sides is normal if you have light colored vinyl stops (or weather trim in laymens terms). If your concrete is level, and the close travel limit on your opener is set correctly, there should not be light coming through the bottom.
Exterior garage doors shall resist the intrusion of embers from entering by preventing gaps between doors and door openings, at the bottom, sides and tops of doors, from exceeding 1/8 inch (3.2 mm).
How to fix a door frame gap without removing the door? Use aluminum strips with a rubber seal. Cut them to size and put around the door. Use Frost King foam stripping. Peel it off, cut it to size and run it along the gap. Use a backer rod to fill gaps. Use wood filler to fill in the gaps.
Deeper bottom weatherstripping can add the extra space necessary to seal gaps from the door to the floor. While you can keep some cold air out with 2-to-3-inch bottom weatherstripping, 3.5 inches or more can help truly resolve the troublesome uneven gap at the bottom of your garage door.
What causes gaps in doors? The most likely reason for the gap is that they were probably prehung in their frames at the factory and installed as a unit. The installer should have adjusted the frame with shims to leave about a 1/8-in. gap along the latch side, about the thickness of two coins when hanging the doors.
Check the Stops
Stops are the rubber trimmings that run the length of your garage door. If the gap in your garage doors runs along the top, sides or bottom edges, your stops may be the culprit. You may need to adjust or replace them. You can also fill small cracks in your stops with caulk.
There should be a 2mm or 3mm gap between the door and the frame on both sides and the top. If you do need to cut the door down to size, keep in mind that you need to cut all four sides of the door equally whenever possible to retain an accurate shape or pattern if the door is panelled.

Garage doors come with weatherstripping on the bottom that should create an airtight seal against your garage floor. The seal helps keep your garage cool in the summer and warm in the winter, while preventing water and pests from entering your home.
The answer is yes if your next question is “Do garage door sensors go bad?” First, take a look at the sensors at the base of your garage door using an infrared beam. If the lenses are dirty or obstructed, the signal won't be received properly, leading to a malfunction.
If you can see light and gaps around your outside door, it is a good indication that your weatherstripping needs to be replaced.
A gap of around 1/8th of an inch is recommended for standard doors to keep the elements out, protect the paint on the trim, and ensure that the door closes and opens smoothly. The right amount of space is equal to the thickness of your door with a little extra room for clearance while opening or closing.
If you can see light streaming through the spaces around your door or feel a draft, there's clearly too much space between the door, floor, ceiling, and walls. What do you do when you suspect these gaps are too big? You reseal your garage door and check for other problems.
Standard Headroom Clearance
At a minimum, the top of the door needs some extra room to make the roll possible. As a standard, garage doors should have a minimum of 10 inches of headroom if they possess extension springs. Or, at least 12 inches for those with torsion springs.
the gap between the underside of the door and unfinished floor should be between 10mm and 22mm, with the ventilation requirements for the building taken into account when determining the gap beneath internal doors.
Concrete Stem Walls
You must have at least 1.5 inches of clearance on each side of the doorIf the stem wall does not provide at least 3 inches of clearance, you will need to consider either cutting the concrete back or adding casing that is flush with the concrete.
The amount of space between each frame will vary depending on the size of your frames, but a good rule of thumb is to leave between 1-1/2” to 2” of space between each frame. My preference is 1-1/2” but whether you go with 1-1/2” or 2”, you'll want to keep that number consistent throughout your entire gallery.

One recommended solution for filling the gaps under a garage door is to use a wider seal than the standard size. The standard seal typically measures 2.5 inches wide, but opting for a wider seal that is 4.5 inches wide, approximately 80% bigger, can do a better job of filling the gaps.
In many cases, an interior door frame pulling away from the wall is a sign of foundation problems. Doorways are built plumb. When a foundation settles, the door frame falls out of plumb which can cause the frame to twist and the door to stick. There are no lasting superficial fixes to this problem.
Apply Flood Paste (cartridge) directly into the gap between the threshold and the bottom of the doors, between the doors, around the lock sets or door handles, and all seams.
